Bathing in cold water is good for the brain.

During the trial, healthy volunteers were immersed in a pool of water at a temperature of 20 degrees Celsius for five minutes, measuring the physiological parameters of the bodies, after which a functional MRI of the brain was performed. It turned out that the brain rebuilt habitual connections to help a person cope with shock. The changes were associated, in particular, with the medial prefrontal cortex and parietal cortex, which control emotions and help maintain attention and make decisions. The scientists now plan to use their findings to better understand the connections between parts of the brain in people with mental illness.
