From the dawn of time until now if there was a purpose to evolution it would be a hot water shower. There is nothing better than to wake up and get under streaming hot water. All your worries melt away. Everything seems like it is as it should be. Just so. Therefore when anything or anyone dares to venture beyond that line of belief, you will pardon me for putting on my snooty best. Disdain. Disbelief. Dismissive. I can think of several words starting with D. But you get my gist. Rivers of blood would flow before I gave up my hot shower.
So is there any science to a cold shower. Cold has been used as a therapy for a while. It reduces inflammation. It constructs the blood vessels on the surface of your skin. To quote a medical research report “Exposure to cold is known to activate the sympathetic nervous system and increase the blood level of beta-endorphin and noradrenaline and to increase synaptic release of noradrenaline in the brain as well. Additionally, due to the high density of cold receptors in the skin, a cold shower is expected to send an overwhelming amount of electrical impulses from peripheral nerve endings to the brain, which could result in an anti-depressive effect.” There was no way I could write that in my language. The point though is clear. Cold water is a pick me up. That is the reason you feel exhilaration when you jump into a swimming pool. It was not the perfect dive but the cold water.
In addition it is believed to reduce muscle stress, stimulate blood circulation and improve your lymphatic system. Some reports even indicate a reduction in levels of uric acid. There are those who propagate the belief that it makes you lose fat. Frankly I haven’t seen any research to support this. I do wish it were true though. Wouldn’t that just be dandy.
So it seems mankind took a wrong turn somewhere. It’s raison d’être seems to be misplaced. When you go jump into your cold shower next perhaps you could come up with a new one.
