You are staying in a hot climate imagining how revitalizing a cold-water shower would be…. Well, it should be, yet only lasts for a short moment.
The truth is, when we are having a cold shower with the whole skin exposed to cold temperature, the nerves in our skin will contract its blood vessels that control about two million sweat glands—meaning, sweating diminishes.
In other words, although a cold shower is able to wash away our body surface heat, it can’t reduce our body’s core temperature through sweating. That explains why we feel so cool and ultra refreshed right after a cold shower, but will experience even hotter in a while.
“What would be more effective, actually, is to take shower that alternates between hot water and cold water, namely, contrast shower,” Traditional Chinese Medicine Practitioners recommended.
In fact, contrast shower not only cools down our body surface and internal body heat, but also increases blood vessels’ elasticity and tenacity through the movements of dilation and contraction, and reduces the risk of the deposition of lipid within the blood vessel wall. What’s more, it is fun.
After all, as our skin is the largest organ we possess, it is important to understand how it works to maintain health—with a little fun.
Tips:
If cold shower is your only option, do it neither with an empty nor a full stomach, suggested by Traditional Chinese Medicine Practitioners. It is because a cold shower consumes you more energy and may cause you having low blood sugar reaction if your stomach is empty.
And while your stomach is full, the cold water will weaken your gastrointestinal motility and the production of digestive juice, increasing the risk for abdominal pain and diarrhea.
