Hydrate, Hydrate, Hydrate!
The best thing you can do for your body in heat is to drink a lot of water. However, optimal hydration also depends on how you drink water. According to the Red Cross, the average person should aim for 3/4 gallon daily, but individual needs vary. Check your urine to understand your own needs; darker yellow urine indicates dehydration.
Additionally, aim for water that isn’t too cold and keep sipping it even if you don’t feel thirsty. Avoid sugary, caffeinated and alcoholic drinks, which can dehydrate you faster. If you take any medications or are on a fluid-restrictive diet, talk to your doctor about your specific hydration needs.
