Everyone says that you should drink eight glasses of water a day to keep your body hydrated but they do not say how hydration can help your body parts. Here are some of the ways staying hydrated can help different parts of your body.
Brain—staying hydrated will help keep your mood stable, your memory sharp, and your motivation intact.
Mouth—it will keep your lips and throat moist and prevent your mouth from feeling dry. If your mouth is dry it can promote cavities, cause unpleasant taste, and bad breath.
Heart—when you are not hydrated your blood volume is lower which in turn makes your heart work harder to pump the lower amount of blood and get enough oxygen to the cells. It makes everyday activities harder to do.
Bloodstream—being hydrated makes your body release heat by expanding blood vessels close to the surface of the skin releasing the heat into the air and better blood flow.
Limbs—being hydrated the water inside and outside of the cells of your contracting muscles will provide adequate nutrients and removes waste more efficiently so you can perform better. Water will also help to lubricate the joints.
Skin—when you are well hydrated your skin has more elasticity.
Kidneys—your kidneys need lots of water to function properly. They need the water to be able to filter waste from the blood and excrete it in urine. It can also help to prevent urinary tract infections if you are well hydrated.
