TIPS FOR REHYDRATION
If you are mildly dehydrated, drink a cup of water. Wait a few minutes before drinking another. Repeat until symptoms resolve.
Replenish electrolytes with diluted fruit juice, salty soup or broth, sports drinks, or water-filled fruits & veggies.
If also overheated, cool off your feet and back of neck.
A NOTE ABOUT CHRONIC DEHYDRATION
Chronic dehydration can occur when someone is mildly dehydrated for an extended period of time—months, years, or even decades.
In this case, it is best to establish new water intake habits based on your body’s needs, which may require re-training your sense of thirst.
