A cold shower can help lift your spirits and reduce irritability. The reason is that cold water affects the "blue spot" in the brain, which produces the hormone norepinephrine, responsible for combating depression.

Because cold water improves the transport of nutrients throughout the body and oxygenates the cells, you become more alert. You get less tired and can concentrate longer on a specific task.

In the morning, for a burst of energy and to wake up faster, a cold shower is exactly what you need. It stimulates cell activity and blood circulation. As a result, you feel more strength and energy to tackle important tasks.
