XTREME Relief™
Why Heat?
Do you know when to use heat or cold therapy for an injury?
The application of therapeutic heat to your body can improve the
flexibility of your tendons and ligaments, reduce muscle spasms, alleviate pain,
and elevate blood flow. The mechanism by which heat relieves pain is not
exactly known, although researchers believe that heat relaxes nerve fibers
which can force muscles into irritating spasms. Heat may also induce the
release of endorphins which are powerful opiate-like chemicals which block
pain transmission.
Increased blood flow occurs in heated parts of the body because heat
tends to relax the walls of blood vessels. Heat appears to be best for
tight muscles and increasing overall flexibility. The proper tissue
temperature for vigorous heating is 104 to 113 degrees Fahrenheit
(40-45 degrees Celsius).
