Water is essential for healthy living. Every cell and organ in the body needs water, so it’s important to have enough especially if you feel stiff and tight in your muscles. Despite the controversy about how much liquid is enough to stay hydrated, there is an easy way to tell if you need to drink more water. Simply use the “snap test” on your hand to see how fast your skin returns to its normal shape. If it takes longer than a second then fill your water glass and start drinking. I can use this test throughout the day to gauge my H2O intake.
