We sweat more in the summer. Have you ever wondered why? Sweat is your body’s way of cooling itself. You sweat more in the heat, while exercising, when you have a fever or when you are nervous. Your body is trying to get back to 98.6 degrees F.
When your body gets hot, water absorbs the heat. It then travels to the blood and eventually is removed by sweating the heated water. As the sweat evaporates, it cools the skin, adding to the cooling effect.
