It’s final exam season for college students across the country. And final exams often come with all-night study sessions and gallons of coffee. But do such things really help?


In recent years, Baylor University researchers have identified a few practices that could help students get enough sleep and retain information for their exams.

Here are some tips pulled from their research.


Say No to All-Nighters


Poor sleep during finals is common as students sacrifice bedtime for study time. Students are under more stress, use more caffeine to stay awake and are exposed to more bright light. Fewer than 10 percent of undergraduates maintain the recommended average of 8 hours per night of sleep or even the recommended minimum of 7 hours of sleep per night.


Baylor researchers Michael Scullin, Ph.D., assistant professor of psychology and neuroscience in Baylor’s College of Arts & Sciences and director of Baylor’s Sleep Neuroscience and Cognition Laboratory, and Elise King, M.I.D., M.A., assistant professor of interior design in Baylor’s Robbins College of Health and Human Sciences teamed together to find out if more sleep equaled better success.


Their December 2018 study found that students who succeeded in averaging eight hours of sleep for five nights during final exams week did better than those who did not. Sleeping for eight hours was associated with a four-point grade boost.


“Better sleep helped rather than harmed final exam performance, which is contrary to most college students’ perceptions that they have to sacrifice either studying or sleeping. And you don’t have to be an ‘A’ student or have detailed education on sleep for this to work,” Scullin said.


King said students know that sacrificing sleep to complete school work is not a healthy choice, but they assume they don't have a choice, often remarking that there aren't enough hours in the day for coursework, extracurriculars, jobs, etc.

“This removes that excuse,” King said.


Sleep Consistency is Key


In a study of sleep and creativity done in 2017, King and Scullin found that interior design students with highly variable sleep habits — cycling between “all-nighters” and “catch-up” nights — had decreased cognition in attention and creativity, especially with major projects.


“Whether or not they ‘pull an all-nighter,’ when students cut their sleep, the effects are obvious,” King said. “They have trouble paying attention during class, and they aren't as productive during studio time.”


To be successful at the challenge, students need to manage their time better during the day. Getting more sleep at night then allows them to be more efficient the next day.


“By training students in their first year of college, if not earlier, that they can sleep well during finals week without sacrificing performance, we may help to resolve the ‘global sleep epidemic’ that plagues students in America and abroad,” Scullin said.


Looking for Better Recall? Tell a Friend What You Learned


Students who are given information and tell someone about it immediately recall the details better and longer, according to a 2017 study led by Baylor psychologist Melanie Sekeres, Ph.D., assistant professor of psychology and neuroscience in Baylor’s College of Arts & Sciences.


She said this “replaying” method takes a lot of effort but is worth it in the long run.

“A week later, the memory was just as good,” Sekeres said. “Telling someone else about what you’ve learned is a really effective way for students to study instead of just re-reading the textbook or class notes.”


In the study, students were shown 24-second clips from 40 films over a period of about half an hour. The study focused on their retention of both the general plot of the films as well as such details as sounds, colors, gestures, background details and other peripheral information that allow a person to re-experience an event in rich and vivid detail, said Sekeres.


“We tell students to test yourself, force yourself to tell someone about the lecture,” Sekeres said. “Even by writing out some question for yourself about the information, then later answering them yourself, you are more likely to remember the information. Unfortunately, simply re-reading or passively listening to a recording of your lecture in hopes of remembering the information isn’t a great study strategy by comparison.”

Trim the Clutter, Keep the Cheer

The holiday season brings warmth, joy and a touch of magic into our homes, but it also can bring excess clutter, waste and energy consumption, making it hard to feel festive. However, there are simple and creative ways to decorate sustainably without sacrificing the festive spirit. Baylor University human sciences and design professor Elise King, M.I.D., M.A., an expert in interior design and built environments, says embracing sustainable decorations, changing to energy-efficient lights, eliminating clutter and reducing waste can help maintain a tidy, eco-friendly home – and create a holiday atmosphere that resonates with joy and meaning. “The holidays can often feel busy and stressful, so it’s helpful to focus on traditions and decorations that bring joy and add meaning to the season,” King said. By taking simple steps to reuse materials, reduce energy consumption and focus on what matters most, families can celebrate the season with both heart and mindfulness, King said. Decorating sustainably One of the easiest ways to approach sustainable decorating is by reusing or repurposing materials you already have or finding decorations at resale shops. "Upcycling items from thrift stores or turning last year’s Christmas cards into garlands are simple and creative ideas," King said. “Beyond thriftiness, these practices add a personal and nostalgic touch to decorations.” King also said that it is important to consider the lifecycle of a product, beyond just being recyclable. "Also consider elements such as durability/longevity, manufacturing processes, transportation, energy consumption and disposal,” she said. “I recommend people make the best-informed decisions they can, while also remembering not to let it become overwhelming. Switch to LED Christmas lights Changing from incandescent to LED Christmas lights is good for both style and sustainability. LED lights reduce energy usage, are more durable and typically last longer than incandescent. Plus, they have come a long way over the past few years. “The criticism used to be that LEDs had a blue hue and were ‘cold’ compared to incandescent,” King said. “That isn’t really the case anymore. You have to be particular about what you purchase, but several companies offer lights that are virtually indistinguishable from vintage lights.” A clutter-free peaceful mindset While holiday decorations create a festive touch around the house, they can add to the clutter and busyness, which ultimately takes away the joy, King said. Decluttering and organization can help create a peaceful environment. “Most people enjoy Christmas decorations, but over the years we tend to accumulate a lot of them,” King said. “Sadly, for many, the thought of decorating for Christmas no longer brings feelings of excitement and joy. Instead, we dread going into the attic, dragging out the tree and boxes of ornaments, checking strands of lights, fixing broken bulbs, etc., only to know that we’ll have to put it all back in about a month. "Keep decorations that bring joy and let go of what no longer feels fulfilling can make a big difference in decreasing the excess while emphasizing what is important to you and your family," she said. By clearing both physical and mental space, families can better prioritize the activities and moments that truly matter. Reducing paper use It can be difficult to go fully paperless because of gift wrapping, but there are ways to reduce paper in the holidays from reusing materials or gifting experiences. “You can reuse paper shopping bags or even cut up the bags or other paper you have around the house and wrap gifts,” King said. Gifting experiences rather than physical items is another growing trend. “I find that many people are interested in receiving or gifting experiences, which can also reduce wrapping needs,” King said. “Not only does this minimize waste, but it also emphasizes shared moments over material possessions.” King noted that since COVID, there has been a trend to go paperless and people tend to be more comfortable with virtual communication and remote collaboration in general, which can also eliminate the need for Christmas cards and other paper products.

Giving with Purpose This Holiday Season

As the season of giving draws near, many people are searching for meaningful ways to support the causes that matter most. From local food banks to global humanitarian organizations, charitable giving offers an opportunity to make a genuine difference – for the organization and for the donor. Two Baylor University experts in consumer behavior and philanthropy – James A. Roberts, Ph.D., The Ben H. Williams Professor of Marketing in the Hankamer School of Business, and Andrew P. Hogue, Ph.D., associate dean in the Office of Engaged Learning and founder of Philanthropy and the Public Good program – share five practical strategies to help donors give with intention and impact. Five ways to give more thoughtfully and effectively 1. Choose a cause that resonates with you Begin by considering the issues that matter most –education, hunger, health care, the environment or another area close to your heart. Once you identify your passion, take time to research organizations working in that space. Look for transparency, measurable results and a strong record of directing funds to mission-focused programs. “A helpful shortcut is to see whether a nonprofit receives repeat grants from charitable foundations,” Hogue said. “Those grants typically follow a rigorous evaluation process.” 2. Decide what you can comfortably give Giving should feel fulfilling, not stressful. Roberts and Hogue recommend reviewing your household budget and determining an amount that fits comfortably. Even small donations can accumulate into meaningful support over time. 3. Consider how often you want to give Think about whether a single contribution or ongoing support works best for you. Regular giving helps nonprofits plan ahead and maintain steady programming. “Consistent donations allow charities to allocate resources more effectively throughout the year,” Hogue said. 4. Automate your contributions Setting up recurring gifts through your bank or directly with a nonprofit keeps your generosity on track with minimal effort. Automatic withdrawals ensure reliability for the organization and ease for the donor. “It’s a simple way to make sure you don’t forget to give,” Roberts said, “and it provides charities with predictable support.” 5. Offer your time and talent if money is tight Financial support is just one form of generosity. Time, skills and personal networks can be equally valuable. “Donating your time and skills can be just as impactful,” Roberts said. “Whether you’re mentoring, sorting donations or helping at events, your presence matters.” Hogue added that giving enriches both the recipient and the giver: “Charitable giving is about making a difference in others’ lives while adding purpose and connection to your own.” His advice: start small, stay consistent and simply take the first step. “Giving is deeply rewarding,” Hogue said. “And as you grow in your generosity, keep a beginner’s mindset – there is always room to improve how we steward the resources entrusted to us.” Looking to know more or arrange an interview?

Dinosaurs in New Mexico Thrived Until the Very End, Study Shows

For decades, many scientists believed dinosaurs were already dwindling in number and variety long before an asteroid strike sealed their fate 66 million years ago. But new research in the journal Science from Baylor University, New Mexico State University, the Smithsonian Institution and an international team is rewriting that story. The dinosaurs, it turns out, were not fading away. They were flourishing. A final flourish in the San Juan Basin In northwestern New Mexico, layers of rock preserve a hidden chapter of Earth’s history. In the Naashoibito Member of the Kirtland Formation, researchers uncovered evidence of vibrant dinosaur ecosystems that thrived until just before the asteroid impact. High-precision dating techniques revealed that fossils from these rocks are between 66.4 and 66 million years old – placing them in the catastrophic Cretaceous-Paleogene boundary. “The Naashoibito dinosaurs lived at the same time as the famous Hell Creek species in Montana and the Dakotas... They were not in decline – these were vibrant, diverse communities.” – Daniel Peppe, Ph.D. “The Naashoibito dinosaurs lived at the same time as the famous Hell Creek species in Montana and the Dakotas,” said Daniel Peppe, Ph.D., associate professor of geosciences at Baylor University. “They were not in decline – these were vibrant, diverse communities.” Dinosaurs in their prime The New Mexico fossils tell a different story than originally thought. Far from being uniform and weakened, dinosaur communities across North America were regionally distinct and thriving. Using ecological and biogeographic analyses, the researchers discovered that dinosaurs in western North America lived in separate “bioprovinces,” divided not by mountains or rivers, but by temperature differences across regions. “What our new research shows is that dinosaurs are not on their way out going into the mass extinction,” said first author Andrew Flynn, Ph.D., ‘20, assistant professor of geological sciences at New Mexico State University. “They're doing great, they're thriving and that the asteroid impact seems to knock them out. This counters a long-held idea that there was this long-term decline in dinosaur diversity leading up to the mass extinction making them more prone to extinction.” Life after impact The asteroid impact ended the age of dinosaurs in an instant – but the ecosystems they left behind set the stage for what came next, the researchers said. Within 300,000 years of their extinction, mammals began to diversify rapidly, exploring new diets, body sizes and ecological roles. The same temperature-driven patterns that shaped dinosaur communities continued into the Paleocene, showing how climate guided life’s rebound after catastrophe. “The surviving mammals still retain the same north and south bio provinces,” Flynn said. “Mammals in the north and the south are very different from each other, which is different than other mass extinctions where it seems to be much more uniform.” Why the discovery matters today The discovery is more than a window into the past – it’s a reminder of the resilience and vulnerability of life on Earth. Conducted on public lands managed by the U.S. Bureau of Land Management, the research highlights how carefully protected landscapes can yield profound insights into how ecosystems respond to sudden global change. With a clearer understanding of the timeline of the dinosaurs’ final days, the study reveals not a slow fade into extinction but a dramatic ending to a story of flourishing diversity cut short by cosmic chance.
