"Studies conducted in Sweden, Finland, and Japan note significant improvement for people suffering from symptoms of rheumatic disease when they use infrared saunas."
It’s actually quite appropriate that arthritis would follow aging in order of health concerns. Wikipedia actually gives one of the most concise and referenced descriptions of arthritis you can find. Here is the introduction as well as the web address:
“Arthritis (from Greek arthro, joint + itis, inflammation; plural: arthritides) is a group of conditions involving damage to the joints of the body.
There are over 100 different forms of arthritis. The most common form, osteoarthritis (degenerative joint disease) is a result of trauma to the joint, infection of the joint, or age. Otherarthritis forms are rheumatoid arthritis, psoriatic arthritis, and autoimmune diseases in which the body attacks itself. Septic arthritis is caused by joint infection.
The major complaint by individuals who have arthritis is pain. Pain is often a constant and daily feature of the disease. The pain may be localized to the back, neck, hip, knee or feet. The pain from arthritis occurs due to inflammation that occurs around the joint, damage to the joint from disease, daily wear and tear of joint, muscles strains caused by forceful movements against stiff, painful joints and fatigue. The most important factor in treatment is to understand the disorder and find ways to overcome the obstacles which prevent physical exercise. (http://en.wikipedia.org/wiki/Arthritis).”
Studies conducted in Sweden, Finland, and Japan note significant improvement for people suffering from symptoms of rheumatic disease when they use infrared saunas. Some of the studies demonstrated rapid improvement over a few sessions of use and others noted a longer regimen (approximately five months of use). All the studies state that participants reported alleviated pain and improved joint mobility (Flickstein, 2007; Hannuksela & Ellahham, 2001; Biro, Masuda, Kihara, & Tei, 2003).
