With temperatures warming up, the idea of a cold shower may be easier to consider. Research indicates there may be many benefits to spending some time under the cold water. And to make this practice even easier, the entire shower doesn’t have to be cold, just a bit at the end.
Researchers theorize that ending your shower with a decrease in water temperature (to about 68F), and staying under the spray for two to three minutes, may trigger neurotransmitters in the brain that produce a sense of well-being.
Cold showers are also said to strengthen the immune system, improve circulation, increase metabolism, alleviate depression, detox, decrease chronic pain, regulate your autonomic nervous system, regulate uric acid levels in your body, and improve sleep.
