Sleep is not just eight hours, allowing you to feel great in the morning, but a whole range of mechanisms that must follow a certain scenario. If the “scheme” for one reason or another fails, there is insomnia or waking during the night, which makes sleep less quality.

We are sorting out whether a full-fledged dream is important, as it is commonly believed, or regular shortfalls do not threaten you with anything other than a decrease in concentration.

Experts SciShow argue that lack of sleep can provoke a lot of health problems. In particular, the experiments allowed us to establish that, with regular sleep shortages, the wounds on the human body heal much more slowly than usual, and the immune system weakens, resulting in the body losing the ability to resist infections.

In addition, lack of sleep can make you more sensitive to pain. Mice deprived of sleep were more sensitive to pain caused by electric current than mice receiving the required amount of sleep. To this should be added and the fact that patients suffering from insomnia, more often report pain in the muscles and joints.

Sleep is of special importance for mental health of a person. In particular, it is during sleep that our brain unites memories, linking them with facts and skills obtained in the learning process. All these cognitive processes significantly improve memory, which means that the night before an important presentation or exam, you really need to sleep – the opposite can be counterproductive.

New research in this area shows that the brain can “self-clean” during sleep. In other words, when we sleep, it gets rid of the toxins that accumulate in the body during the day. Although this is a fairly recent discovery, it can affect the study of Alzheimer’s disease, which, according to the expert community, should be attributed to the accumulation of toxins in the brain.
