Sweating is your body responding to the rise in your core temperature during a workout. This is your body's attempt to regulate temperature and cool down. People often equate heavy sweating to calorie expenditure. Wearing a sweat suit increases perspiration and helps you lose more weight than wearing shorts. However, the extra weight you lose wearing sweats is not from burning extra calories and there is risk associated with doing so.
Sweating and Burning Calories
When the sweat glands open up and wets the skin during exercise, it then evaporates, which cools the skin. Although sweating is a sign that you are exerting yourself, it is not an accurate indicator of how many calories you are burning. In fact, you burn more calories exercising in cooler temperatures with lighter clothing, such as shorts, because your body needs to work more to get warm, thus burning more calories. According to Wayne Askew, director of nutrition at the University of Utah, temperatures cool enough to make you shiver increases your calorie expenditure, although this is not an effective strategy for those with high body fat.
Shedding Water Weight
Running in sweats helps you lose weight by shedding more water weight when you are performing aerobic exercise. Dropping water weight doesn't impact your calorie burn rate, so if your goal is to lose weight, it doesn't matter what you wear. To burn calories, you should increase your heart rate through intense exercise, such as playing basketball or sprinting and by engaging large muscles with strength training. A sweat suit can be uncomfortable to wear during a workout so wearing shorts and a t-shirt or athletic tights will be more appropriate.
Sweating it Out
Athletes often wear sweats to increase the loss of water weight, which is quickly replaced once you drink water or a sports drink. This is beneficial for athletes, such as boxers or mixed martial artists, who need to вЂњmake weightвЂќ for an event. By losing only water weight, athletes can re-hydrate and be as big as possible for the event. For example, an athlete weighing in at 180 pounds may end up performing at 195 pounds after putting the water weight back on.
Associated Risks and Benefits
Wearing sweats can increase the risk of dehydration or heat stroke when you exercise under hot conditions. To avoid this, stick to a moderately-intense workout when wearing a sweat suit and wear shorts along with a light t-shirt for intense exercise. The sweat producing effect of wearing a sweat suit can help some people work out more often due to the perceived increase in weight loss.
