Stress helps the body adapt to changes in the environment. Changes in heart rate and blood pressure prepare us to act quickly, whether it's a physical threat or a pending deadline. However, over time, chronic stress can affect sleep, mood, and digestion. Stress seems to increase risks of anxiety, depression, obesity, Alzheimer's disease, and heart disease.

The amount of water you drink affects whether an event is stressful. A study of 52 subjects found that drinking more water leads to significant mood improvement, less fatigue, less confusion, and less sleepiness. The study found that drinking less water reduced feelings of calm, content, and positive emotions. A different study of 120 women found that the amount of water a woman drinks is associated with mood state.
