Cool Down with a Cold Shower
A hot shower encourages blood flow toward your skin, soothing your
muscIes. You relax. You feel good. A cold shower does the opposite. In
response to the cold temperature, your body will do its best to protect
your internal organs, encouraging the blood to flow away from the outer
extremities and skin. Why is this good?
When you exercise, your
heart rate increases to support your body's needs. Lactic acid builds up
in muscIes when they're deprived of oxygen, a normal occurrence when
your workout is intense and your body dips into its energy reserves
(glucose) to meet the intense energy need. When people talk about
"feeling the burn," it's the lactic acid that's behind that bite.
Cold temperatures immediately after your cool-down help bring your heart rate down and increase your circulation, which in turn helps reduce your recovery time. The increased level of blood your heart pumped to match your body's needs won't be allowed to pool in your tired musc1es, and those musc1es will clear the lactic acid more quickly.
Additionally, exercise
can cause m*scles to become inflamed -- the swelling caused by small
tears in the m*scle fiber -- and a cold shower may help to minimize soft
tissue inflammation and its associated pain.
Overall, if you're
healthy, a cold shower after aerobic exercise may help to constrict
blood vessels and decrease your metabolic activity, which equals less
tissue damage and less swelling. Endurance athletes may want to try
something a little more intense as part of their cool down: ice baths.
An ice bath involves soaking in cool water for 15 to 20 minutes
post-workout, and you can decrease the temperature as you begin to
adjust to the cold. Accompany your cold shower with a sports massage,
and you'll not only reduce the build-up of lactic acid in your
post-workout mus.cles to reduce soreness and swelling, but you'll also
boost your circulation and loosen tight musclles.
