• Rehydrate, of course! Mild dehydration can be easily treated at home by drinking more water.
• Drink water or sports drinks (sports drinks can replace electrolytes, salt lost through sweating and other water loss).
• According to the Institute of Medicine, Men should drink 13 glasses of water a day (about 3 liters) and women should drink about 9 glasses a day (about 2.2 liters)

Many of us have heard the 8×8 rule: drink eight, 8 oz. glasses of water a day to stay hydrated. However, this advice isn’t supported by hard scientific evidence. But it is close to the recommended amount of water we should drink and is easy to remember. That’s why it sticks around, but we should be drinking more water than the 8×8.
