Your body needs water to function. Because you constantly lose water through breathing, perspiration, urine, and bowel movements, you have to replenish your body's water supply regularly.
Research originally recommended that you drink 8 ounces of water eight times a day. However, newer guidelines suggest that you drink water when you’re thirsty — unless you require extra water due to your activity level, where you live, whether you are pregnant or breastfeeding, and your health. If you let thirst be your guide, you will likely meet your body's hydration needs.
According to the National Academies of Sciences, Engineering, and Medicine, adequately hydrated women consume an average of 2.7 L of water each day, while men consume about 3.7 L daily. These values cover fluids from water, other beverages, and food.

Water is essential to your survival. In your body, water works by:
Regulating your body temperature

If you lose more water than you take in, you can easily become dehydrated. Common causes of dehydration include, vomiting, diarrhea, fever, infections, and not drinking enough water in hot climates or when exercising. The symptoms of dehydration in adults are:
