Water makes up 60 percent of your body and is essential to every single cell. So it’s no surprise that research suggests that college students who brought water with them into an exam scored higher marks than those who did not.
Hydrations not only impacts your brain, but your entire body. Here are a few ways water benefits us everyday.
1. Water helps prevent dry mouth.
Dry mouth can cause bad breath and/or an unpleasant taste–and can even promote cavities.
2. Water aids cardiovascular health.
Dehydration lowers blood volume, so the heart has to work harder to pump blood and get oxygen to your cells, which makes everyday activities more difficult.
3. Water keeps your body cool.
When you’re dehydrated it takes a higher external temperature to trigger blood vessels to widen, so the body stays at a higher temperature.
4. Water helps muscles and joints function
When well hydrated, water inside and outside the cells of contracting muscles provides nutrients while removing waste so you perform better. Water is also important for lubricating joints.
5. Water keeps skin supple.
When a person is severely dehydrated their skin has less elasticity. This is different than dry skin, which is usually the result of harsh soaps or exposure to extreme environmental conditions.
6. Water helps cleanse your body.
The kidneys need water to filter waste from the blood and excrete it in urine. Staying hydrated can help support the urinary tract and kidney functioning.
