Saunas are available in many gyms and spas with the intention of offering a relaxing activity for patrons. However, some people are questioning whether sitting in a sauna can also provide an easy, exercise-free way of losing weight. Unfortunately, saunas are not recommended as a weight loss tool. Instead, experts suggest using saunas for relaxing and rejuvenating tired muscles.
Features
A sauna is powered by either electricity or burning wood. Traditional saunas typically include a pile of hot rocks. Users throw water on the rocks to release steam into the air and to increase the sauna's interior temperature. Other saunas are heated with infrared energy coming from heat lamps. While conventional saunas are generally heated to between 180 and 220 degrees Fahrenheit, infrared saunas are only heated to between 100 and 130 degrees Fahrenheit, says AltMed, a Creighton University Medical Center website.
Misconceptions
The high temperatures in saunas cause profuse sweating, which many believe will lead to weight loss. Many people may find their weight drops slightly after exiting a sauna. However, this change results from the water weight which is lost from sweating and dehydration. As soon as the individual drinks any fluids, says UAB Medicine, the weight will be regained immediately. The University of Utah also warns that dehydration of the body can actually work against a person's efforts to lose weight because it may slow the body's metabolism.
Warning
Sweating to lose weight can have serious health risks. Military.com warns that using a sauna or sweat suit to lose weight can result in heat stroke, kidney damage, cardiovascular-related emergencies or even death. UAB Medicine advises anyone using a sauna to exit the room immediately if they begin to feel nauseous or dizzy or get hot or cold chills.
Considerations
Only healthy adults should use saunas. Older adults and children under five are advised to avoid saunas. Pregnant women should not use saunas either since elevated body temperatures may cause birth defects, says UAB Medicine. People who take medications regularly and those with heart problems or high blood pressure should consult a physician before using a sauna.
Potential Benefits
Though more evidence is needed to form solid conclusions, studies have linked sauna use to a variety of health benefits. AltMed reports that improvements in blood pressure and heart function may result from sauna use. The heat therapy in a sauna may also provide positive results for those who suffer from chronic pain or depression. In some cases, it may even lessen the risk for heart disease.
