It's easy to forget to drink enough water during the colder months, but now that summer is here, it's especially important that we keep our bodies hydrated. If you don't drink enough, you can get headaches, feel nauseous, or find it hard to concentrate. The NHS recommends six to eight glasses of water daily, but you may lose track with everything else that goes on in your life. You can easily conduct a simple skin test to determine if you're hydrated enough.
It relies on "skin turgor," which is your skin's elasticity, or how easily it changes shape and returns to normal when pulled or pressed. Skin with normal turgor should be able to snap back very quickly.
You can test your skin turgor if you pinch the skin on the back of your hand for a few seconds. If it immediately returns to normal, you are hydrated enough; if it doesn't, you need to drink more water.
