A good night's sleep is the best way to start the day right, but did you ever ask yourself what happens to your body during the night? Here are some things to know: During sleep our skin releases a substantial amount of moisture (from 0.3 to 1.5 liters), literally detoxifying the body. The growth hormone leads the regeneration of the body, which produces new cells, renews the muscle tissues and decreases sensitivity of pain. The level of cortisol (stress hormone) in the blood during sleep comes down to its minimum; the same happens with the hormone that causes the sense of hunger. In addition, most of the long-term procedural memory is created in the first part of the sleep while the body burns fat, because the new cells need energy. The immune system produces antibodies to all types, so the saying "With a good night's sleep, everything passes by" is not too far from the truth. And did you know that during sleep we turn ourselfes from five to ten times per hour, almost without realizing it, to increase blood circulation in the pressurized parts when we stand still in a position?
