3.You May Gain an Athletic Edge
Even mild dehydration can make you tired. So it makes sense that athletes who replace the sweat they lose with water and electrolytes (minerals like sodium and potassium) have lower body temperature, more muscle, stronger hearts, more brain power, and more energy. It all adds up to better performance.
4.You Could Lose Weight
People who had just 2 or 3 more cups of water a day seem to have less fat, sugar, salt, and overall calories through the day. That means proper hydration could help you lose weight. Extra water can replace empty, sugary calories many people drink with meals. Water also seems to speed up your metabolism, and it takes up space in your stomach so you feel more full.
