Blood Pressure Reduction

Only Sunlighten saunas have clinical research showing a reduction in both systolic & diastolic blood pressure from regular use, key factors in maintaining a healthy heart.

Regular use of a Sunlighten infrared sauna is good for your heart! In the U.S. alone, one in three adults suffers from heart disease, stroke or some other form of cardiovascular disease. High blood pressure increases your risk of getting heart disease, kidney disease or serious stroke.

Only Sunlighten saunas have been clinically determined to provide one of the best, natural ways to lower blood pressure. Sunlighten’s Solocarbon heaters were shown in a clinical study with the University of Missouri Kansas City in 2005 to lower blood pressure through 30 minute infrared sauna session three times per week. The study concluded that Sunlighten infrared sauna therapy reduces blood pressure because the heat dilates blood vessels and reduces the volume of their inner lining, thus increasing circulation to promote healthy blood pressure.

Additionally, a Japanese study published in the October 2008 issue of The Journal of Cardiology examined the clinical efficacy and safety of infrared sauna therapy compared to standard therapy for patients with chronic heart failure. The report concluded that far infrared-ray dry sauna therapy is both safe and effective at improving clinical symptoms and cardiac function as well as decreasing cardiac size in chronic heart failure patients. Repeated infrared sauna treatments improved impaired blood vessel functions in patients with high blood pressure, diabetes and high cholesterol. This suggests a preventive role for infrared sauna use for arteriosclerosis.

Improved Circulation

Owning and using a Sunlighten sauna for infrared therapy is like giving yourself a passive cardio workout…whenever you need it!

Heating your muscles with Sunlighten infrared rays produces an increase in blood flow similar to that seen during exercise. In fact, blood flow with infrared sauna use has been reported to rise from a normal rate of 5-7 quarts per minute to as much as 13 quarts per minute.(1)

The elevation in body temperature from Sunlighten sauna use also produces an increase in blood flow for the benefits of a passive cardiovascular workout. Regular infrared sauna use—especially in the mid IR range—has been shown to significantly stimulate blood flow, even after your sauna session is done. A cardio workout has never been so relaxing!

Another benefit of improved circulation from Sunlighten sauna use is quicker muscle recovery post-workout. The increased peripheral circulation from our infrared heat reduces inflammation, decreases pain and speeds healing, all important steps in helping the body recover.

More health experts recommend Sunlighten saunas than any other because of proven effectiveness. According to Dr. Rachel West, D.O., “The cardiovascular cleansing properties of Sunlighten saunas allow the circulatory system to have increased circulation and oxygenation while lowering blood pressure.” Dr. Mark Hyman, New York Times bestselling author and editor-in-chief of the peer-reviewed medical journal Alternative Therapies in Health & Medicine, owns a Sunlighten sauna and says, “Sunlighten saunas improve circulation, help with weight loss, balance blood sugar and improve detoxification.”
