It is well known that infrared heat has a positive effect on muscular pain. Doctors use infrared to treat tensions, arthritis, swellings, stiffness, tissue illnesses and other muscular problems.
Muscle stiffness: A good exercise for injured or stiff muscles is to warm up your muscles to 45° degrees before doing stretching exercises. Your stretch can be improved up to 50% and will last even after finishing your exercises.
Circulation: Circulatory disorders can lead to several problems. Infrared heat helps to restore circulation and thus improve blood flow significantly so that symptoms will disappear.
Heart and vascular diseases: Chinese scientists discovered infrared heat can be used in the treatment of heart attacks. The well-known macro-biotic expert Hermann Aihare made similar discoveries. If blood is burdened by cholesterol and fat, red blood cells can clump together and thicken the blood. It will then transport 20-30% less much-needed oxygen to inner organs, tissues and cells. Lack of oxygen leads to pain and to reduced blood flow. This causes high blood pressure which in turn can lead to a heart attack.
Relieving stiffness of joints: A temperature of 45°C returns mobility to stiff finger joints with decreased function at room temperature level. A similar effect has been noticed for other joints.
Easing pains: A relaxation of the muscles helps to ease other pain as well. Sciatica is caused by muscle problems and infrared heat can help to break this vicious cycle. Heat eases pain around the nerve root and its surrounding tissue.
Stimulation of blood flow: The warming of certain body parts helps the blood vessels to expand and stimulate better blood flow towards other body parts. Just like physical exercise, a warming of the muscles helps to stimulate blood flow.
Speed up healing processes: Heat contributes to a faster recovery after illnesses, heals inflammation and contributes to sweating. Experimental cancer treatments with heat have been promising, however these are still at the very first stages of investigation.
