Increases endorphins
Depression affects at least 10 percent Trusted Source of American adults, according to the Centers for Disease Control and Prevention. Many drugs treat depression, depending on the severity or duration of symptoms. One holistic method of treatment that’s gaining popularity is hydrotherapy. Taking a cold shower for up to 5 minutes, 2 to 3 times per week, was shown to help relieve symptoms of depression in a clinical trial.
For people with depression, cold showers can work as a kind of gentle electroshock therapy. The cold water sends many electrical impulses to your brain. They jolt your system to increase alertness, clarity, and energy levels. Endorphins, which are sometimes called happiness hormones, are also released. This effect leads to feelings of well-being and optimism."
"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."
