Regardless of the time of year, the body can become dehydrated quickly and suddenly. Dehydration is when the body loses too much fluid to function properly. According to the American Academy of Family Physicians, the body normally loses water when we urinate, sweat, and breathe. It can easily become dehydrated when the weather is hot and humid. We sweat more in those conditions.
Why we need water
More than half of the body is made up of water. Water nourishes and assists the body in many ways. A few of its uses are getting rid of waste and regulating body temperature. Water also helps regulate heart rate and blood pressure, protect joints, and moisturize skin.
Be proactive
The body cannot survive without water. The best method of rehydration is prevention. The easiest way to monitor whether or not you are getting enough water is to check your urine color. If your urine is dark, you will need to get more fluids in your body. A clear or light yellow hue is the desired color for urine.
Tips for staying hydrated
Most people can get enough water each day by drinking based on their level of thirst. They can also get enough water by eating plenty of fruits and vegetables. People who exercise heavily or are outdoors in hot weather for long periods of time should drink water more often. This will help to prevent dehydration. The National Athletic Trainer's Association (NATA), an organization for certified athletic trainers, recommends planning outdoor exercises in the early morning or late evening. The NATA suggests that people exercising outdoors drink sports drinks in addition to water.
Sports drinks are popular with athletes because they contain electrolytes. Electrolytes supply the body with sodium that is often lost through heavy sweating. However, most people can be sufficiently hydrated with water. Water is the best beverage choice because it does not have any added calories or sugar.
