Amid "Likes" and "Shares," Facebook Jeopardizes Children's Health and Safety
On February 4, 2004, a 19-year-old Mark Zuckerberg launched “TheFacebook.” Developed in his Harvard University residence hall, it began as a networking service for his roughly 7,000 classmates. Today, it is the most popular social media platform in existence, boasting over three billion monthly active users worldwide. Through two decades of “likes” and “shares,” Facebook has transformed how people connect, interact and think. Driving everything from dinner parties and concert outings to political campaigns and protest movements, it has frequently been celebrated for its ability to convey information, mobilize groups and galvanize change. However, it has also been criticized for its questionable content management choices, its suspect data collection practices and, perhaps most notably, its role in feeding an ever-growing mental health crisis among children and adolescents—a charge Zuckerberg refutes. Elizabeth Burgess Dowdell, PhD, RN, FAAN, is a professor in Villanova University’s M. Louise Fitzpatrick College of Nursing and an expert on the health and safety risks posed by social media. From her perspective, Facebook and platforms like it have undoubtedly played a part in heightening levels of emotional distress and physical harm among youths. “Statistically, it’s well-established in the literature that mental health issues and concerning behaviors among children have escalated tremendously,” said Dr. Dowdell. “They’re becoming sadder, more depressed and lonelier, even though they’re very connected.” To Dr. Dowdell’s point, mental health disorders began rising precipitously among young people in the years following Facebook’s launch. Per the Centers for Disease Control and Prevention (CDC), the percentage of children aged 6 to 17 years “ever having been diagnosed with either anxiety or depression” increased from 5.4% in 2003 to 8% in 2007 and 8.4% in 2011-2012. And just last year, in the era of Instagram and TikTok, Mental Health America found that 11.5% of children in the United States were struggling with severe depression, with 16% of youths aged 12 to 17 years having experienced a major depressive episode in the past 12 months. A contributing factor, according to Dr. Dowdell, is the way social media construes reality. Flooded with images, posts and videos that show hyper-idealized, rose-colored representations of life, impressionable young users can be made to feel isolated, inept or dissatisfied with their appearance. “I think adults understand that a ‘perfect’ picture is often preceded by a dozen other photos,” she said. “Kids don’t always see it like that. They focus on what makes them happy and what makes them sad—and what makes them feel sad about themselves.” Tragically, throughout the social media age, this sadness has been tied to increasing rates of suicide, self-harm and risky behavior among youths. A 2023 CDC study found that the suicide rate for children aged 10 to 14 years tripled from 2007 to 2018 (from 0.9 deaths per 100,000 to 2.9), and in 2021-2022, the National Center for Missing and Exploited Children noted a 35% year-over-year increase in reports of suspected child sexual exploitation. Amid these frightening statistics, Dr. Dowdell emphasizes the importance of caring, compassionate adults’ involvement in young people’s lives. She notes these individuals’ presence can not only shield youths from potentially hazardous situations but give them the tools to cope with traumatic episodes and feelings of despair. “The critical factor that helps children become resilient is having a support system—having family members, parents or trusted adults with whom they can talk,” Dr. Dowdell shared. “They might go down the rabbit hole, but they have someone to pull them out, someone to help them.” For adults concerned about their loved ones’ social media use, Dr. Dowdell stresses that empathy and understanding are key. In turn, she advocates for an approach that reflects the supposed purpose of Facebook and platforms like it: active conversation. “It all comes back to communication,” she said. “Parents and guardians need to role-model responsible behaviors. They need to talk about these things: ‘What did you look at today?’ ‘What was good?’ ‘What was bad?’ ‘What did you think?’ ‘How did you feel about that?’ “It’s much like, when children are little, reading them books. When we read to children, we engage them… Why not read the social media feeds, look at the Facebook posts or go through Instagram? These forms of engagement, the conversations we have, let them know they can come and talk.”
The U.S. House today passed a federal bill to ban TikTok and it now moves to the Senate. President Biden said he would sign a potential bill that bans the social media platform. Goizueta Business School Professor David Schweidel has done extensive research on the impact of social media. He says: The security and privacy issues around TikTok are only one part of the equation. User safety is another concern that all social media companies are now facing. He notes that the algorithms prioritize engagement, which could be showing people content that is harmful to them (mentally and/or physically). Background: TikTok is owned by ByteDance, a private Chinese company that claims all information gathered through the app is secure. Lawmakers do not agree and have plans to remove TikTok from the U.S. by September 30th unless ByteDance sells TikTok. The proposed bill would also put into place allowance for the executive branch to prohibit access to an app owned by a foreign adversary that could impact national security. Expert Source: David A.

The digits of pi are infinite. It’s an irrational number—one whose decimal never ends and never repeats. Over time, with brilliant minds and brilliant technology, humans have been able to calculate its digits further and further, now forming a 100-trillion decimal tail. In many ways, the infinitely long decimal expansion of pi is a metaphor for its limitless applicable value. With new ways of thinking, measuring and computing, the significance of pi has permeated throughout the study and use of mathematics and countless other disciplines. Pi is a mathematical constant by definition and also because of its ubiquity. “To offer an Augustinian-themed analogy, pi is to mathematics as Gregor Mendel’s peas are to biology,” said Katie Haymaker, PhD, associate professor of mathematics and statistics at Villanova University. “At first glance, Mendel’s experiments convey some basic understanding of the function of genetics. However, the way genes are expressed is incredibly complicated, and scientists continue to study genetics and gene therapies today. Similarly, mathematicians today study objects that are historically tied to the development of ideas inspired by explorations of pi. Pi is one gateway to a garden of mathematical possibilities.” Dr. Haymaker currently teaches a course called “Mathematics for Human Flourishing,” inspired by the Francis Su book of the same title. Her class discusses math in everyday life and how engaging in mathematical exploration can develop virtues like studying ethics or other humanities can and also expand quality of life. “I don’t have class this Pi Day, but usually I would share a little something about pi if I did,” she said. So, what exactly is pi? The easy answer is that it’s the ratio of the circumference (the length all the way round) to the diameter (the length across) for any circle. “If you measure across a circle with a piece of rope, how many pieces of the same rope would you need to measure around?” Dr. Haymaker explained. The never-ending answer starts with 3.14, hence the common celebration of Pi Day on March 14. This value has been studied for millennia: The ancient Egyptian Rhind Papyrus, dating to around 1650 BCE, offers a very close estimation for pi as 3.16049. Even the Bible, in 1 Kings 7:23, a circular vessel is described, and the ratio of circumference to diameter calculated to exactly three. “There are interesting explorations by biblical scholars about why this number is not exactly the value that we now know as pi, including that the brim around the vessel accounts for the discrepancy,” Dr. Haymaker said. Over time, novel methods for approximating pi were discovered, advancing humankind’s understanding of its value, and leading to various other paths of mathematical study. The famous Greek mathematician and inventor Archimedes, for instance, discovered a way to approximate pi’s value by use of a regular polygon (a closed geometric figure made of equal straight lines and angles). In those times, measuring a circle was not well defined, according to Dr. Haymaker. By placing the regular polygon inside the circle, the straight lines can be measured, those straight lines can be split to form a regular polygon with more measurable sides, and so forth. The more sides, the closer the measurement is to the true circumference of the circle. “That whole idea of approximating to the actual value is the main idea of calculus,” she said. “This notion by Archimedes predated that entire field.” Later, formulas were developed that surpassed Archimedes’ technique. A better approximation of pi was discovered around the year 450 by Chinese mathematician Tsu Ch’ung-chih, arriving at the easy-to-remember fraction 355/113. “This is one rational approximation to pi, and it’s also a fun Pi Day party trick because it’s the best approximation you can get with a fraction like this whose denominator is less than 10,000,” Dr. Haymaker said. These are just two examples of the many contributions made to advance the understanding of pi. Even the use of the Greek symbol to describe the ratio, which was popularized by 18th-century mathematician Leonhard Euler, was instrumental. Prior to that, there had been no agreed-upon symbol and the concept was often described using only words. In the thousands of years since the first recorded approximation of pi, the methods of its approximation—and pi itself—have been applied to multiple other fields of mathematical study such as trigonometry and calculus. For Dr. Haymaker, pi was important in the development of her own understanding of mathematics as well. “I have learned to expect the unexpected when it comes to pi,” she said. “It shows up in all sorts of places and it inspires us to dig deeper into why.” Today, pi can be calculated to 100-trillion decimal places (though only a dozen or so are needed for even the most accurate applications). On Pi Day 2023, 21-year-old Rajveer Meena memorized the first 70,000 digits, breaking a Guiness World Record in a mind-boggling 10-hour recitation. “I think that pi is fascinating to people because its digits behave in a random way and they go on forever,” Dr. Haymaker said. “If there is a string of numbers that is special to you—take 1842 for example—it exists somewhere in the digits of pi. In exploring pi, it feels like you are exploring the infinite, which naturally inspires mystical feelings about the number.” By the way, the string of numbers 1842 (the year Villanova was founded) appears at position 1738 counting from the first number after the decimal, according to the Pi-Search Page. So, whether it’s on March 14, July 22 (because the fraction 22/7 is a rational approximation of pi) or whenever you might celebrate, look down at that beautiful circular dessert you will cut into and think about “why pi(e)?” “Some people may scoff at Pi Day as being separate from ‘real’ mathematics,” Dr. Haymaker said. “But there is a joyfulness in celebrating this day that represents a deep connection that people have to mathematical discovery. After all, a person wrote the Rhind Papyrus, and it is people who program the computers that searched for the 100 trillionth digit of pi. This quest to understand is a deeply human endeavor. “To quote Francis Su, ‘the pursuit of math can, if grounded in human desires, build aspects of character and habits of mind that will allow you to live a more fully human life and experience the best of what life has to offer.’ So, if eating pie and other round foods on March 14 inspires someone to learn, ask questions, pursue answers and see themselves as an explorer of mathematics, then it is indeed a day to celebrate.”
The countdown is on for the total solar eclipse on April 8 and Adam Frank, professor of astrophysics, science commentator, and popular author, is available to comment on: Earth's eclipses are the result of a cosmic accident! No other world has such a relatively large moon. Our Moon is the result of a titanic collision with a Mars sized planet more than 4 billion years ago. Earth is likely the only planet that experiences a solar corona/ring of fire during a total eclipse. That's because the size of the moon and the size of the sun appear to be roughly the same from Earth. The moon is slowly drifting away from the Earth so the kind of eclipses we experience are also an accident in time. Were not possible before, won't be possible later. Eclipses must have been terrifying for early humans. Learning to predict them helped establish the possibility for science. Today eclipses can be a way to help people understand and appreciate the sciences. The science surrounding the eclipse is the same science that gives us vaccines and helps us understand climate change (science is science). The "devil comet" may be visible during the eclipse. The comet passes by Earth every 71 years. The comet, which glows green and red, gets its nickname from outbursts that take on the shape of horns. Adam Frank is a frequent on-air commentator for live interviews and segments in national media outlets. He also regularly contributes to written publications, including The Washington Post, The Atlantic, The New York Times, and Scientific American. In 2021 he received the Carl Sagan Medal, which recognizes and honors outstanding communication by an active planetary scientist to the general public. It is awarded to scientists whose efforts have significantly contributed to a public understanding of, and enthusiasm for, planetary science. His most recent book is The Little Book of Aliens (Harper Collins, 2023).
What exactly is edge computing and how does it relate to self-driving cars? A University of Delaware expert has been diving deep into the subject through the university's Connected and Autonomous Research Laboratory (CAR Lab). Weisong Shi is a professor and chair of the Department of Computer and Information Sciences at UD, where he leads the CAR Lab. Edge computing is how scientists move computations closer to the user. Self-driving cars have to gather and process big batches of data to work, and in a short amount of time. The time spent sending data to a physically distant server and then back again may cause delay that could impact real-time decisions. Shi's research with edge computing is working to alleviate that issue without turning every car into a supercomputer that consumes a lot of computing power and energy. Shi and his team are building a world-class live research and education infrastructure on the STAR Campus at the University of Delaware. He can be reached by clicking his profile.

The centre is to receive almost £8 million of government money while the remainder will be made up through match funding and support from industry and the four universities. The government has described it as part of the UK’s biggest-ever investment in engineering and physical sciences doctoral skills, totalling more than £1 billion. The Aston University centre will focus on the use of biomass to replace fossil fuels and removal (or capture) of CO2 from the atmosphere, with the potential to create new sources of fuels and chemicals. Integration of these two areas will lead to significant cost and energy savings. Called NET2Zero, the centre will train PhD students across the full range of engineered greenhouse gas removal techniques including direct air capture, CO2 utilisation (including chemical and material synthesis), biomass to energy with carbon capture and storage, and biochar. The students will work in the centre’s laboratories exploring the conversion of feedstock into alternative energy, improving conversion processes and measuring how the new technologies will impact the economy. Supported by a range of relevant industrial, academic and policy partners the centre will equip students to develop the broad range of skills essential for future leaders in decarbonisation. NET2Zero will be led by Professor Patricia Thornley, director of Aston University’s Energy and Bioproducts Research Institute (EBRI). She said: “I am delighted that this centre for doctoral training has been funded. The climate emergency is so stark that we can no longer rely on demand reduction and renewables to meet our decarbonisation targets. “If we are to have greenhouse gas removal options ready in time to be usefully deployed, we need to start now to expand our knowledge and explore the reality of how these can be deployed. This partnership of four leading UK universities with key industrial and policy partners will significantly augment the UK’s ability to deliver on its climate ambitions.” “We are absolutely delighted to be working with our partners to deliver this unique and exciting programme to train the technology leaders of the future. Our students will deliver research outcomes that are urgently needed and only made possible by combining the expertise and resources of all the centre’s academic and industry partners.” Science and technology secretary, Michelle Donelan, said: “As innovators across the world break new ground faster than ever, it is vital that government, business and academia invests in ambitious UK talent, giving them the tools to pioneer new discoveries that benefit all our lives while creating new jobs and growing the economy. “By targeting critical technologies including artificial intelligence and future telecoms, we are supporting world class universities across the UK to build the skills base we need to unleash the potential of future tech and maintain our country’s reputation as a hub of cutting-edge research and development.” Centres for doctoral training have a significant reputation in training future UK academics, industrialists and innovators who have gone on to develop the latest technologies. The University of Nottingham’s Dr Eleanor Binner said: “We are absolutely delighted to be working with our partners to deliver this unique and exciting programme to train the technology leaders of the future. Our students will deliver research outcomes that are urgently needed and only made possible by combining the expertise and resources of all the Centre’s academic and industry partners.” Her colleague Professor Hao Liu added: “We look forward to providing our best support to the NET2Zero CDT, including using our past and existing successful experience in leading other centres, to make this an exemplar.” Overall, there will be 65 new Engineering and Physical Sciences Research Council (EPSRC) centres for doctoral training which will support leading research in areas of national importance including the critical technologies AI, quantum technologies, semiconductors, telecoms and engineering biology.

Turning the City Green! Georgia Southern celebrates Savannah's 200th St. Patrick's Day Parade
Savannah’s St. Patrick’s Day Parade is one of the largest in America, right behind New York City and Chicago. Comprised of Irish heritage, marching bands, traditional dancers and elaborate floats, people come to Savannah from all over the world to participate in the local parade. And as the city looks to commemorate the 200th St. Patrick’s Day Celebration this year, Dr. Howard Keeley, the director of Georgia Southern University's Center for Irish Research, is a crucial member of the global Irish community. Notably, he said the fact that St. Patrick’s Day celebrations are still prevalent and evolving come down to several things. Firstly- he says that people with Irish heritage in Savannah have such a hyper-local pride. There were three main neighborhoods the Irish settled in- East Savannah, Yamacraw, and Frogtown - and a lot of local Irish people now can trace their lineage back to one of those neighborhoods. He also says that Irish immigrants were received very well into the Savannah community unlike in some other places, such as the Northeast. That cultural integration has allowed Irish pride to be woven into the fabric of Savannah and he says that Irish people also love to share their heritage with others. So, it’s only natural that St. Patrick’s Day celebrations have continued on for this long. ”It’s the Irish and everybody else. There’s a phrase that has come into being, I think it was coined by the Irish government, but when you think about the phrase it makes so much sense. And that is ‘affinity diaspora’, so diaspora referring to the Irish that live abroad, but affinity meaning anyone can be Irish. That you align with certain values that Ireland wants to stand for, values of inclusion, values of cultural vibrancy, and you know, Ireland is welcoming,” said Keeley. Keeley was recently in the news for receiving the 2023 Presidential Distinguished Service Award for the Irish Abroad from the Government of Ireland. It is the highest honor the country of Ireland can give to a person who is a non-resident. This will be an exciting event, and if you're looking to speak to Howard Keeley simply click on his icon now or contact Georgia Southern's Director of Communications Jennifer Wise at jwise@georgiasouthern.edu to arrange an interview today.
It used to be the go-to place for college students looking to blow off steam, escape winter or just hang out with their friends - Florida was the place to be for spring break. However, it seems parts of Florida are now saying 'thanks but no thanks' to the annual party crowds. Meanwhile, Florida said ‘yes’ to more gambling which may attract more tourists interested in placing bets and vacationing in the state. These topics have received a lot of coverage lately, and there are still outstanding questions and points to consider: What impact will spring break clampdowns and actions have on local businesses? What parts of Florida are poised to benefit the most of expanding gambling tourism? How will these developments affect Florida’s largest employer, the tourism economy? And, what else is changing in Florida’s tourism industry Florida’s tourism industry is one of the largest in the world, and it has a major economic impact for the United States and beyond. If you are a reporter following the tourism industry and how Florida’s is changing - we're here to help. Peter Ricci is the Director of the Hospitality and Tourism Management program in Florida Atlantic University’s College of Business. He is a hospitality industry veteran with more than 20 years of managerial experience in segments including food service, lodging, incentive travel and destination marketing.

Municipalities around the world have invested significant resources to develop connected smart cities that use the Internet of Things (IoT) to improve sustainability, safety and efficiency. With this increased demand for IoT experience, the VCU College of Engineering formed the OpenCyberCity testbed in 2022. The 1:12 scale model city provides a realistic, small-scale cityscape where students and researchers can experiment with new and existing smart city technology. Sherif Abdelwahed, Ph.D., electrical and computer engineering professor, is director of OpenCyberCity. He recently answered some questions about new developments within the testbed. The OpenCyberCity is a smart city testbed, but are there any real-life cities that one could call a smart city? Several real-life locales are considered smart cities due to their extensive use of technology and data-driven initiatives to optimize infrastructure and services. Dubai is one of the most notable. They have implemented smart transportation systems, buildings and artificial intelligence to transform the city’s operations and make them more efficient. Other reputable smart cities include Singapore and Seoul, which utilize smart energy management, smart transportation and comprehensive data analytics for improved urban planning and services. Seoul, in particular, has an initiative with smart grids and connected street lights, which VCU Engineering’s own OpenCyberCity test bed is working to implement. How does the OpenCyberCity address privacy? With so much technology related to monitoring, how are individual citizens protected from these technologies? Privacy is a major concern for smart cities and it is one of the main research directions for VCU Engineering’s OpenCyberCity. We are developing several techniques to prevent unwanted surveillance of personal information. Sensitive data is protected by solid protocols and access restrictions that only allow authorized users to view the data. Our aim is to find a reasonable middle ground between technological progress and privacy rights, staying within legal and ethical bounds. Some techniques to address privacy concerns include: Data Anonymization: This makes it difficult to trace back information to individual identities. Within the testbed, we will evaluate how to protect individual privacy while maintaining data utility and assess the impact on data quality. Secure Data Storage and Transmission: Encrypt data to protect it from unauthorized access. In the smart city testbed, these access control mechanisms will be implemented within the testbed’s infrastructure. We will also test different data handling processes and access control models to determine their ability to safeguard sensitive data. Privacy Impact Assessments: Regularly evaluate potential privacy risks of new smart city projects in order to mitigate them and ensure the ethical handling of data by those with access. Policy and Regulation Development: Data and insights generated from OpenCyberCity experiments can inform the development of cybersecurity policies and regulations for smart cities. How is the College of Engineering’s OpenCyberCity test bed different from similar programs at other institutions? While other universities have similar smart-city-style programs, each has their own specialty. The VCU College of Engineering’s OpenCyberCity test bed focuses on real-world contexts, creating a physical space where new technologies, infrastructure, energy-efficient transportation and other smart city services can be tested in a controlled environment. Our lab monitors real-time data and develops smart buildings, smart hospitals and smart manufacturing buildings to enhance the city’s technologies. Recent additions to the OpenCyberCity allow for expanded research opportunities like: Advanced Manufacturing: Students can apply advanced manufacturing techniques in a controlled environment. They can also test new materials, processes and automation technologies to improve efficiency and product quality. Energy Efficiency Testing: Environmental engineers and sustainability experts can evaluate energy consumption patterns within the smart manufacturing unit to implement energy-saving measures and assess their impact on sustainability. Production Optimization: Manufacturers can use real-time data from the smart manufacturing unit to optimize production schedules, minimize downtime and reduce waste. Predictive maintenance algorithms also help prevent equipment breakdowns. Education and Training: Hands-on experience with state-of-the-art manufacturing technologies helps train the workforce of the future. Integration with Smart City Services: Data generated by the manufacturing unit can be integrated with smart city services. For example, production data can inform supply chain management and energy consumption data can contribute to overall city energy efficiency initiatives. How has the OpenCyberCity changed in the last year? Is the main focus still data security? What started with research examining, analyzing and evaluating the security of next-generation (NextG) applications, smart city operations and medical devices has expanded. Data security is now only one aspect of OpenCyberCity. Its scope has grown to encompass more expansive facets of cybersecurity like automation and data analytics in the domain of smart manufacturing systems. The implementation of a smart manufacturing system in 2023 is something students really enjoy. Thanks to the vendor we used, undergraduate students had the option to develop functionality for various features of the manufacturing plant. Graduate students were also able to research communications protocols and cybersecurity within the smart manufacturing system. What does the smart manufacturing system entail and what kind of work is occurring within that system? An automated system is there for students to work with. Robot arms, microcontrollers, conveyor belts, ramps, cameras and blocks to represent cargo form an environment that emulates a real manufacturing setting. We’re currently brainstorming an expansion of the smart manufacturing system in collaboration with the Commonwealth Cyber Initiative (CCI). We plan to set up two building models, one for manufacturing and one for distribution, linked by a sky bridge conveyor system that moves items between the locations. Students work to leverage convolutional neural networks that use images to facilitate machine learning. When paired with the advanced cameras, it forms a computer vision system that can accurately place blocks in a variety of lighting conditions, which can be a challenge for other systems. By having to optimize the communication protocols that command the smart manufacturing system’s robotic arms, students also get a sense for real-world constraints . The Raspberry Pi that functions as the controller for the system is limited in power, so finding efficiencies that also enable stability and precision with the arms is key. Is there an aspect of cybersecurity for these automated systems? Yes. Devices, sensors and communication networks integral to the IoT found in smart manufacturing systems and smart cities generate and share vast amounts of data. This makes them vulnerable to cybersecurity threats. Some of the issues we look to address include: Data Privacy: Smart systems collect and process vast amounts of data, including personal and sensitive information. Protecting this data from unauthorized access and breaches is a top priority. Device Vulnerabilities: Many IoT devices used in smart systems have limited computational resources and may not receive regular security updates, making them vulnerable to exploitation. Interconnectedness: The interconnected nature of smart city components increases the attack surface. A breach in one system can potentially compromise the entire network. Malware and Ransomware: Smart systems are susceptible to malware and ransomware attacks, which can disrupt services and extort organizations for financial gain. Insider Threats: Employees with malicious intent or negligence can pose significant risks to cybersecurity. Potential solutions to these problems include data encryption, frequent software updates, network segmentation with strict access controls, real-time intrusion detection (with automated responses to detected threats), strong user authentication methods, security training for users and the development of well-designed incident response plans.
Sleep Better, Live Better: Improving Sleep Quality Can Lead to Less Stress and Improved Cognition
Research has demonstrated that increased stress and all-night study sessions can lead to lower cognitive functioning and test scores, adding even more pressure on college students. Baylor sleep expert Michael K. Scullin, Ph.D., director of Baylor University’s Sleep Neuroscience and Cognition Laboratory and associate professor of psychology and neuroscience, studies how cognitive and behavioral processes are affected by sleep. “Sleep deprivation makes life worse. And it makes the person not getting enough sleep worse at life,” Scullin said. “However, if we focus on improving our sleep, life will get better, and we will get better at life.” Poor sleep is particularly common when students are studying for exams or working on major projects for classes. The combination of staying up late, cramming for tests, increased stress and bright light exposure late at night can lead to variable sleep durations and higher stress levels. “We know that as you accumulate sleep debt, whether it's from a single all-nighter or from weeks of variable sleep durations, it can exacerbate any pre-existing vulnerability a person may have to stress,” Scullin said. “For instance, if someone has a predisposition to panic attack disorder, sleep deprivation can increase panic attacks by about 40%. This applies to virtually any clinical or subclinical condition, whether it’s stress-related or not – sleep deprivation makes it worse.” Scullin added that even with a slight sleep deficit, any sort of negative event, such as a bad grade on a test, will feel much worse than it would for someone who is well-rested. “It becomes a cycle, and the individual begins to focus on what is worse instead of calming down at night and getting ready to fall asleep,” Scullin said. So how can a student – or any individual – break this cycle? It all starts with developing healthy sleep habits, which reduce stress and improve academic performance. Scullin suggests students try three Challenges to improve their sleep, mood and stress regulation. 1. Illuminate! Challenge One class activity that Scullin has used with students for years is called the Illuminate! Challenge, which focuses on students adding more natural sunlight to their lives in the morning hours. “About 90% of students do not know that we need natural sunlight daily in the morning to tell our internal biological clock when to start ticking. When our biological clock knows it's time to start ticking, it will make us feel more alert, which helps improve our mood,” Scullin said. Specifically, he suggests: Spending 20 minutes daily outdoors in natural daylight during the morning hours. Be intentional with this time as something aside from walking to class or other daily routines. Take the time when you would normally be inside studying or eating breakfast to go outside instead. “Almost every one of my students who has taken this challenge has said their mood and alertness improved,” Scullin said. 2. Deluminator Challenge The Deluminator Challenge eliminates light in your bedroom for a night of better sleep. Scullin said this challenge works by: Turning off all the lights and counting the number of artificial lights that exist in your environment. How many of your plugs have lights? How much light is coming in through your curtains? Cover up every light source (except fire alarms and other safety devices), including any light coming through windows. Blackout curtains are a good investment, or even using blankets to cover windows will help reduce light at night. It’s easy to adopt this challenge as it is sustainable once it is set. You will find that you can fall asleep easier and enjoy sleeping later in the morning because of the darker environment. “What normally happens is students see their devices are emitting unnatural light, and it is not nearly as dark as it should be,” Scullin said. “A lot of students in my classes report that this is their favorite challenge because it led to the biggest impact on sleep quality.” 3. Anti-Rumination Challenge Lying in bed thinking about everything you need to do the next day can increase stress levels and interrupt sleep. In a recent study, Scullin found that taking five minutes to write a “to-do” list at bedtime helped student participants fall asleep about 10 minutes faster than others who used that time to chronicle completed activities: Take five minutes to write down a to-do list of everything that needs to be done the next day. The to-do list offloads stress, gives you a good action plan for the next day and helps you feel accomplished as you check off the goals. When people get more sleep – even just one more hour of sleep per night – “they literally become happier,” Scullin said. That extra hour of sleep can improve social relationships, emotional reactions and cognitive functioning. With improved cognitive functioning comes improved academic performance. “Adding more sleep to your life makes life better, and it's going to make you better at life. It's going to resolve some of the stress, and you're going to better handle events that are inherently stressful. You're going to enjoy life while you're also taking classes. And you know what? Your grades are probably going to improve.”
