The human body needs proper and good flow of blood within the blood vessels. Sufficient blood circulation ensures a steady supply of nutrients to all parts of the body; it also cleanses the system as blood takes away impurities and toxins from different body parts. Hence, overall well-being is dependent on good blood circulation. Lack of sufficient blood circulation leads to many cardiovascular ailments, nervous disorders, diabetes, arthritis, body aches, muscular strains, cramps, menstrual pain, fatigue, stretch marks, stomach disorders and many more ailments and diseases.

Infrared sauna exposes the body to radiant heat through infrared rays. These rays delve deep into the body for around one inch to one and half inches. These hot rays raise body temperatures to around 110-130 degrees Fahrenheit. Such high temperatures create a fever like situation within the body, similar to hyperthermia. All vital organs gear to meet and combat the situation. As a result, the heart pumps harder and faster. The heat and additional pumping of the heart dilates blood vessels, which now carry more blood and blood circulation increases. Simultaneously, the body produces sweat to cool body temperatures. Increased blood circulation and perspiration work together to help eliminate various toxic materials from the body.

Increased heart beat leads to blood flow of around 13 pints a minute from the normal 5-6 pints. Increased circulation strengthens the circulatory system as metabolic rate increases and the diastolic rate of blood falls lowering blood pressure. All body tissues receive oxygenated blood, which leads to better performance of important body organs like lungs and kidneys. For arthritic sufferers, arthritic pain is reduced immensely as kidneys are now more capable of excreting lactic acid deposits in the joints. Detoxification through sweat is responsible for cleansing body tissues and passages thereby increasing and easing better flow of air within nasal passages. Sinus problems disappear.

Further benefits of improved blood circulation through sauna are reduction in body weight. Increased heart beat and pumping uses more calories as you burn around 300-600 calories in a half hour sauna session. Better supply of oxygenated blood through your arteries helps skin disorders and ailments like acne, psoriasis and eczema. It acts as a deep cleanser and moisturizer for skin giving a refreshed and glowing look to your skin. Perspiration due to increased heartrate clears clogged skin pores and improves tone, elasticity and texture of skin. Open wounds may heal faster with reduced scarring.

Infrared induced hyperthermia has therapeutic effects on both body and mind. Regular users of the infrared sauna have blood vessels that are more elastic and flexible. This reduces incidences of Arteriosclerosis Coronary Artery Disease, and Hypertension. The nervous system receives good and oxygenated supply of blood, which helps in keeping the brain alert and active, reducing all nervous ailments. The circulatory system, being the most important body system regulates and controls functioning of all other systems. The  use of the infrared sauna keeps this important system in tip-top condition and promotes an overall feeling of well-being.

Journal of the American College of Cardiology (Publication- October 4, 2001) stresses on beneficial effects of regular saunas on coronary heart disease patients. High cholesterol, diabetes, and hypertension are mainly due to clogged blood vessels and hardening of arteries as in atherosclerosis. These ailments in turn lead to many more body ailments and diseases. Infrared sauna therapy yields positive results on such patients. A fifteen-minute sauna bath at temperatures of around 140° degrees Fahrenheit followed by half an hour rest in bed covered with blankets daily for two weeks shows significant improvements in their ailments.
