Water transports nutrients throughout the body and is important for temperature regulation. How much water you should drink a day depends on your age, activity level, diet, medications, and the climate. However, experts recommend the average healthy adult should drink eight, 8-ounce glasses of water a day or around two liters. A great way to tell if you?re drinking enough water is to check the color of your urine, and how often you have to pee. Urinating every two hours is normal, however, only urinating every six hours means you are not drinking enough water. Needing to pee every 30 minutes is a sign that you?re drinking too much water. If your urine is dark yellow you are likely dehydrated and if it?s light yellow or clear you are drinking enough water. Another way to check if you?re drinking the recommended daily intake of water is to check the elasticity of your skin. Pinch the skin of the back of your hand for a few seconds, if the skin quickly snaps back into place you are well hydrated. If it takes a couple of seconds to go back to normal then you're are dehydrated. Other signs of dehydration include dizziness, brain fog, and fatigue
