National Hydration Day

Celebrated on 06/23/2026

Quick Fact

National Hydration Day is celebrated on June 23rd, the birthday of football player Korey Stringer, who tragically died from heatstroke in 2001. His mother, Kelci Stringer, founded the Korey Stringer Institute to promote hydration and heat safety. This day reminds us that even mild dehydration can impair cognitive function and physical performance.

Origins and Establishment of National Hydration Day

National Hydration Day was established in 2017 by the Korey Stringer Institute (KSI), a nonprofit organization focused on preventing sudden death in sport and promoting hydration. The date, June 23rd, honors the birthday of Korey Stringer, a Minnesota Vikings offensive tackle who died from heatstroke complications during training camp in 2001. His mother, Kelci Stringer, co-founded KSI with experts from the University of Connecticut to educate athletes and the public about the dangers of dehydration and heat illness.

Evolution and Modern Commemoration

Initially, National Hydration Day was observed primarily through educational campaigns by KSI and partnerships with sports organizations. Over time, it has grown into a broader public health awareness day. Today, it is marked by social media campaigns, hydration challenges, and community events. Companies and schools promote water intake, and many use the day to distribute reusable water bottles or share tips on staying hydrated. The day also serves as a reminder of the importance of hydration in daily life, not just for athletes.
