Are You Dehydrated? Pinch Your Hand To Tell.

Dr. Kidner recommends a simple test to check your hydration level. Pinch the back of your hand. Healthy, hydrated skin snaps back into place, but if you’re dehydrated, the skin is slow to return to normal.

Don’t Overdo It
Description

It is possible to drink too much water. Hyponatremia is a condition in which water dilutes the blood, resulting in low sodium levels. Long-distance runners and athletes are often at risk, so if you’ve got an intense endurance exercise planned, make sure you replace some of your water with sports drinks to maintain balance.
