7 Science-Based Health Benefits of Drinking Enough Water (2 of 4)

Regulates brain function

Hydration plays a huge role in brain function and energy levels. Mild dehydration, which is just 1 to 3% of the body’s water content, can have a significant impact on brain function. A study in women revealed that just a 1.4% loss of fluid impaired both mood and concentration levels. Levels as low as 1 to 3% is just about 4.5 pounds of body weight for a person weight 150 pounds. This kind of fluid loss can occur just from simple, everyday activities.

Treats headaches and pains
