how water affects body
3. Water Flushes Toxins from Your Body. Staying properly hydrated is the only way we can effectively purge our bodies of toxins. It's like cleaning up a construction site, says Horowitz.
5. Water Helps You Sweat. Sweating may be embarrassing sometimes (such as when it's visible on your clothes), but it's a necessary function, as it regulates and cools your body temperature. It's a huge boon whenever you're exercising, but if you're not properly hydrated, you won't be able to sweat as much as you need to.
6. Water Helps You Exercise. Not only does water keep your internal heat gauge in check when you're running laps or shooting hoops, but it also physically assists you while you do those things (and any other physical activity).
4. Water Keeps You Regular. This is closely related to flushing toxins (it's part of the same process, after all), but there are other benefits to having regular bowel movements than ridding the body of pollutants.
