Ways to celebrate

National Hydration Day exists because a high school football coach turned his players' worst problem into an invention, and the day itself became his memorial.

The coach who invented a hydrating mouthguard

Victor Hawkins, a high school football coach, kept seeing his players struggle through practices and games because of dehydration. Rather than just telling them to drink more water, he partnered with SafeTGard to design a mouthguard called FuelGard that slowly released electrolytes into a player's mouth during play, keeping them hydrated without needing a water break. When Hawkins died in 2012, SafeTGard established June 23 as National Hydration Day in his honor, and the observance has since grown from an athlete-focused campaign into a general reminder for everyone to drink enough water.

Ways to mark the day

  • Track how much water you actually drink today against how much you think you drink.
  • Swap one sugary or caffeinated drink for water.
  • Set a refill reminder if you tend to forget water during a busy workday, the exact problem Hawkins was trying to solve for athletes.
