Water helps the body keep a normal temperature, and water loss can decrease cognitive function, headaches, and fatigue. People lose about 10 cups of fluids a day, so it's important to stay hydrated, especially during these warmer months! Sip water throughout the day to help the body meet its need for ongoing hydration. To know how much water your body needs, try this guideline: take your body weight in pounds divided by two; the result is the number of ounces of water to drink each day. Stay safe and hydrated, everyone!
