Grabbing a cup of coffee first thing in the morning may seem like the best move but it is not

After going several hours without a sip, a serving of water first thing can hydrate the body while aiding digestion and metabolism

Over night, the body can become relatively dehydrated, says Dr. Maria Peña, who specializes in obesity medicine at Mount Sinai in New York

Rehydrating first thing in the morning helps build a healthy habit and can build a routine that will allow people in getting enough water for the entire day

Drinking water doesn't cause a significant calorie burn, but "it does ensure that your metabolism is functioning optimally," Alissa Rumsey

By drinking water, a person will urinate more and have more bowel movements, which is the body's natural way of getting rid of waste

Proper hydration also aids our bodies. It keeps skin plump and joints lubricated. Additionally, drinking water can help with fatigue, often felt in the morning.

Drinking water also won't make you gain weight, Peña says. "Our bodies self regulate."
