The new study involved 3,000 people. Scientists have found that a cold shower did not protect people from health problems, including colds and flu. However, thanks to the cold, people rarely took sick leave. In addition, a cold shower shortened the duration of the hospital, reports "MedikForum".

Most participants complained of some discomfort in the cold shower. Nevertheless, 91% wanted to continue taking it. 64% of volunteers continued to take a cold shower after the study.

Experts do not know exactly what causes the positive effect of a cold shower. Experiments on animals have shown: under the influence of cold temperatures in the body, beta-endorphins are produced that help cope with pain. Another method of taking a cold shower is a burst of energy comparable to what people feel when they use a cup of coffee.
