Doug Casa, PhD and COO of the Korey Stringer Institute

When we went looking for a hydration soulmate, we found him in Dr. Douglas Casa. As passionate about hydration as CamelBak, Doug literally stumbled his way into his field of study. At a 10k championship race in New York state at the age of 16, he collapsed from exertional heat stroke and dehydration. He fully recovered after 5 hours in a coma and intensive medical care. Ever since, he has dedicated his life to the study of hydration, exertional heat stroke, heat-related illnesses and preventing sudden death in sport. He is the COO of the Korey Stringer Institute (KSI) at the University of Connecticut, which he founded with Kelci Stringer.

Watch this short clip to learn more about the incident that propelled Doug into the study of exertional heat stroke and how he became COO of the Korey Stringer Institute.


Doug and his team work with athletes, soldiers and laborers of all levels and abilities, including NFL players to ensure they perform safely on and off the field. But Doug takes most pride in the institute’s efforts to make grassroots changes at the high school sports level, leading his KSI team to make critical health and safety policy changes across the country. He has authored over 140 peer-reviewed research studies and has successfully treated 155 exertional heat stroke victims (with 0 fatalities). Additionally, he regularly works with numerous media outlets, including the NBC Today Show, Good Morning America, ESPN, CNN, PBS, Sports Illustrated, USA Today, Wall Street Journal and the New York Times.

When we asked Doug about why hydration is so important to performance during intense exercise in the heat, he encouraged us to start with the basics: “If you’re hydrated, you’re cooler. When you’re cooler, you perform better.” Share Doug’s passion and learn from his wisdom and research with our regular updates on HydratED.
