Hydration is an important part of your overall health, and it's recommended that you drink at least half of your body weight in ounces of water every day.
So, for example, if you weigh 180, you should drink 90 ounces of water every day. This keeps your joints lubricated and healthy.
You also need to nourish your body with healthy foods.
When you supply your body with the nutrients it needs to meet its demands on a daily basis, you'll feel better by default.
You'll also have more energy, and all of your bodies functions will improve, including your nervous system.
