Many health professionals say that the human body needs between 7 and 8 hours of sleep a night to get fit. Our energy and our mood during the day depends essentially on the number of hours we slept the day before, and an hour more or less can make all the difference. As for our food needs,
You are often hungry:
When we lack sleep and therefore energy, our body increases its production of ghrelin, a neurotransmitter responsible for the sensation of hunger, to balance certain hormones including serotonin and dopamine. Just as if you are a night owl, you will tend to snack late at night, it is because your body requires carbohydrates to stay awake at a time when it should rest.
You have concentration problems:
Like food, sleep is essential for our mental faculties, including our faculties of concentration. During sleep, our brain rebuilds our memory. This is why it is important for students, for example, to sleep early the day before their exams. In this case, it can lead to memory lapses and a lack of concentration.
You must sleep more if you are often sick:
Sleep is directly related to the immune system. When we sleep, our body produces the antibodies needed to protect us from disease. That is why if you miss sleep, you are more likely to contract flu, sore throats, colds and so on. It is therefore important to sleep enough and fortify your body with vitamins.
You have trouble making decisions
As with concentration, lack of sleep impairs the decision-making ability. This difficulty can obviously be related to a lack of self-esteem or self-confidence, but lack of sleep can also be responsible.
You are often in a bad mood
Aside from your hormones and the overwork of work, lack of sleep can also make you irritable. Studies have shown that lack of sleep can trigger emotional problems such as depression, irritability, lunatics etc.
