Heat and cold and Magnetic
Therapies are the most common types of noninvasive and no addictive pain-relief
therapies for muscle and joint pain. Which one you use depends on whether the
pain is new or recurring.
Heat opens up blood vessels, which
increases blood flow and supplies oxygen and nutrients to reduce pain in joints
and relax sore muscles, ligaments, and tendons. The warmth also decreases
muscle spasms and can increase range of motion. Applying superficial heat to
your body can improve the flexibility of tendons and ligaments, reduce muscle
spasms, and alleviate pain.
Cold slows down blood flow to an injury,
thereby reducing pain and swelling. Cold therapy slows circulation, reducing
inflammation, muscle spasm, and pain. It should be used if the area is swollen
Magnet therapy involves applying a magnet
to the skin or close to the skin to improve a
condition such as pain.
There is interest in magnet
therapy for medical conditions due to the variety of electromagnetic fields
that naturally occur within the body. For example, nervous system transmissions and related muscle contractions are associated with magnetic
activity. The heart generates the largest magnetic field in the body. Several
other activities in the body are associated with magnetic activity.
