The heat does the following 6
- Enhances vasodilatation* so that more blood is delivered to the
- Allows oxygen In the blood to detach from the hemoglobin more
- Speeds up the breakdown of glucose and fatty acids.
- Makes muscles more elastic, less susceptible to injury.
- Elevates your metabolism and burns fat more easily.
- Increases perspiration and therefore detoxification.
You are changing the construction of your body as you perform
these postures. Think of it as a piece of steel. When the steel is
hot it becomes soft. When the steel is cool, it is easier to break
and does not bend as easily. The heat makes your body more
malleable. Warm muscles are more elastic and less susceptible to
injury. Warmer temperatures produce a fluid-like stretch that
allows greater range of motion. Cold muscles don't absorb shock or
impact as well and aren't stretched as well so they get injured
Additionally, the oxygen and blood exchange rate is more rapid so
you are getting more oxygen to your tissues, and your heart is more
efficient. It is clearing out the valves of the heart chambers. It
helps to flush out the arteries. Sweating is important because it
takes the majority of the workload off the kidneys and the liver
allowing the skin, which is the largest organ of the body, to
excrete toxins. It exfoliates the skin by ridding the dead skin
cells, so your skin will become clearer.
The capillaries that weave around the muscles respond to the heat
by dilating. This brings more oxygen to the muscles and helps in
the removal of waste products such as carbon dioxide and lactic
* When blood passes through warm muscles oxygen releases more
easily from the hemoglobin. Blood passing through cold muscles
releases less oxygen.
** Warm muscles burn fat more easily than cold ones. Fat is
released during stress. The stress of intense exercise causes a
deluge of fatty acids into the blood stream. If you exercise with
cold muscles, the muscles cannot use the fatty acids, and the fatty
acids end up in places where they aren't wanted, such as the lining
of the arteries.
NOTE: Muscles aren't the only beneficiaries of
heat. Higher temperatures improve the function of the nervous
system, meaning that messages are carried more rapidly to and from
the brain and spinal cord.
