When sad, take a cold shower

Winter comes with gloomy days that often make people sad. But just taking a cold shower can cure and even prevent moodiness.

Cleanliness is a pleasant side effect, but the key lies in the water temperature.

Study author Nikolai Shevchuk at Virginia Commonwealth University in the US believes that everything originates from a brain region called locus ceruleus, or "sad spot". Cold water baths will stimulate this point - the brain's main noradrenaline supply, which helps regulate depression.

" The antidepressant effect may lie in cold water, causing the body to shudder and sending mild shock to the brain, helping to stimulate the 'sad spot.' hot receptor times, so shocking the brain . "

According to Shevchuk, depression is caused by two factors. The first is genetics. The second is because of the lack of physiological stresses in the lifestyle, such as sudden changes in body temperature, to help activate the body's defense system.

During the evolution of mammals and primates, individuals must exercise a lot and are constantly exposed to changes in body temperature, such as swimming in cold water while hunting or chasing children. bait in the hot sun.

Sudden changes in body temperature are similar to a homeopathic therapy, whereby a small amount of harmful things becomes beneficial, as it stimulates the body's recovery system. Electric shock or brain stimulation works according to this principle. That is why electric shocks are used to treat depression.

However, cold water baths should not be applied to heart patients or other serious illnesses. Doctors recommend cold water bath - about 20 degrees Celsius - in 2-3 minutes, 1 or 2 times a day. Previously it had to get used to the temperature for about 5 minutes.
