History of National Hydration Day
National Hydration Day is often linked to sports and efforts to help athletes stay hydrated during intense activity. One commonly repeated story connects the day to a specially designed mouthguard created to make it easier for players to drink water during training and games. After the inventor’s death, the product was commercialized and became available to a wider public. The observance is typically dated to 2016.
