Exercising should be a priority year-round, but summer heat and humidity can challenge that commitment and make it harder to meet your daily step goal. Daniel White, associate professor of physical therapy at the University of Delaware, offers some practical tips for reporters working on stories about staying active and safe during the hottest months of the year.


1. Time it right

Plan to exercise in the early morning or evening hours when temperatures are cooler. Delaware’s scenic beaches and boardwalks can be the perfect spot to catch a summer breeze or stop to enjoy the scenery while getting your steps in.


2. Prioritize hydration

In the heat, people perspire more and need to replenish fluids. Always carry a water bottle with you and sip from it regularly. Dehydration can lead to lightheadedness, balance issues, muscle cramps and even heat stroke. And don’t forget sunscreen — SPF is necessary for any outdoor workout year-round.


3. Reduce the intensity

It may not feel like as much of a workout, but the fact that you’re out there pounding the pavement is the most important thing. According to the U.S. Department of Health and Human Services’ Physical Activity Guidelines for Americans, movement is beneficial, and the more, the better. Performing any physical activity at half intensity far outweighs not doing it at all.


4. Opt for the indoors

Pickleball has become all the rage, so finding an indoor court or other activities you can enjoy in air conditioning is a great alternative. Walking on a treadmill at the gym or getting in laps at the Christiana Mall are good options too during a heatwave.


5. Dive in

Swimming and water aerobics are great ways to stay active and keep cool. Facilities like the YMCA have designated lap-swim-only hours or classes. Simply splashing around can be an easy way for those just starting their fitness journey to incorporate more movement into their days.


6. Walk with purpose

The bottom line is the more you walk, the healthier you’ll be. Just 3,000 steps a day is a solid start, according to White’s studies, especially for older adults. Reaching 6,000 steps has been shown to protect against arthritis complications. But when it comes to steps, the sky’s the limit. Walking at a moderate pace, where you’ve built up a sweat, will strengthen your muscles and bones and lower your risk of cardiovascular disease and cancer.

How Trade Wars Are Reshaping Fashion and Apparel

Trade disputes and tariffs have become an increasingly common part of the global economic landscape, with the fashion and apparel industry often caught in the crossfire. University of Delaware professor Sheng Lu can explain how these disruptions reshape sourcing decisions, supply chains, prices and the products ultimately available to consumers. Lu can discuss: • How new tariffs, including those on Canadian jackets and wool products, could affect consumers, fashion companies and apparel supply chains. • How tariffs can affect apparel prices and product availability for U.S. consumers. • Why fashion and apparel supply chains are particularly vulnerable to trade policy changes. • The impact of trade disputes on fashion companies and retailers in the U.S. and abroad. • What previous trade disputes can tell us about the potential consequences of tariffs.

Epidemiologist Available to Discuss Measles, Vaccination and Infectious Disease Outbreaks

As measles cases continue to rise in the United States, University of Delaware epidemiologist Jennifer Horney is available to discuss measles outbreaks, vaccination, vaccine hesitancy and the challenges of preventing the spread of highly contagious infectious diseases. The deaths of two unvaccinated Pennsylvania residents from measles — the first measles deaths in the state in 35 years — underscore the continuing public health risks posed by the disease. Horney, a former member of the Centers for Disease Control and Prevention’s Board of Scientific Counselors, is an experienced epidemiologist who studies infectious disease outbreaks and public health preparedness. Horney can discuss: • Measles outbreaks and transmission: Why measles is among the most contagious infectious diseases and how outbreaks spread. • Vaccination: The effectiveness of the MMR vaccine and the importance of maintaining high vaccination rates. • Vaccine hesitancy and misinformation: What influences vaccination decisions and how public health messaging affects perceptions of vaccine and infectious disease risks. • Measles prevention and treatment: Why outbreaks can reemerge when vaccination coverage falls, and the role and limitations of vitamin A and other treatments. • Outbreak response and preparedness: How public health officials investigate and respond to measles and other infectious disease outbreaks, and what can be learned from previous outbreaks.

Experts on earthquake response, community recovery and building safety

The shaking from a major earthquake may be over in minutes, but its consequences will last for years. University of Delaware experts can address emergency response, distributing aid, assessing damaged buildings, helping vulnerable communities and planning for long-term recovery. Their expertise is particularly relevant as communities across Latin America respond to major earthquakes, including the deadly magnitude 7.4 earthquake in Colombia. Tricia Wachtendorf, co-director of UD’s Disaster Research Center, offers expertise on how governments, nonprofits, emergency responders and community groups coordinate following a major disaster. Her research examines the role of spontaneous or “emergent” groups, humanitarian aid and donations, and how communities and organizations respond in the aftermath of disasters. Jennifer Trivedi, associate professor of anthropology and Disaster Research Center faculty member, specializes in disaster vulnerability and why some communities are more severely affected than others. She also addresses the long-term recovery needs and planning that emerge after the immediate crisis. Michael Chajes, professor of civil and environmental engineering, provides expertise on the structural damage caused by earthquakes, why some buildings collapse while others withstand the shaking and how engineers assess damaged structures and improve earthquake resilience.
