Drinking enough water is one of the best things you can do to improve your health and reduce your risk of minor medical problems.
Adverse effects from not drinking enough water include fatigue, digestive issues, headaches, skin conditions, bladder and kidney problems. The body needs water as much as the air, and keeping your body properly hydrated is extremely important.
Dehydration actually begins just before you start feeling thirsty, and consuming water throughout the day is the best way to maintain proper hydration.
Not having enough water can cause enzymatic activity in the body to slow down, and blood will thicken and impede blood flow resulting in high blood pressure.
