Does this photo make you thirsty? Staying hydrated is one of the easiest ways to improve your mood & energy level! When our cells become dehydrated, they are sluggish and don’t function quite as well. An easy way to figure out how much water you should be drinking is to take your weight in pounds and divide by 2 – that’s how many ounces of water you should get in a day! It’s easy to remember on a hot summer day, but make sure to drink enough water in the cold, dry winter months as well!
