You may think you can function just fine on little sleep, but don't skip the sleep you need because your health depends on it.
Read below what happens in the body if you don't get enough sleep.
The brain works less
Lack of sleep reduces blood flow to the parts of the brain that control more demanding thought processes. It impairs your problem-solving skills, slows your cognitive speed, and impairs constructive thinking and logical reasoning, said Dr. Richard Shane.
You can't remember
Research has shown that sleep strengthens the nerve connections that control memory and supports the process in which new information becomes adopted information, i.e. memory. Lack of sleep interferes with the memory process.
You are irritable
The part of the brain that is responsible for thinking and logical reasoning is usually in balance with the part of the brain that controls emotions such as fear, anger, anxiety. Magnetic resonance imaging showed that in sleep-deprived people, the connection between these centers in the brain decreases, and everything results in the appearance of fear, anger, and irritability, reports razvodna.hr.
You drive badly
Lack of sleep not only endangers your health, it can also affect the lives of other people if you drive without sleep. According to numerous studies, lack of sleep reduces the feeling of alertness and impairs the ability to perform complex functions such as driving. The fact that lack of sleep slows down our reactions to the same extent as alcohol is also incredible.
You're gaining weight
There is growing evidence that sleep deprivation affects hormones associated with weight management. In sleep-deprived people, a large increase in the hormone called ghrelin, which is responsible for creating appetite, has been observed. On the other hand, the hormone leptin, which brings the appetite back to normal in the same people, is produced in very small quantities. When we are tired, our metabolism slows down in order to conserve energy, and at that moment bad things accumulate in the body and we gain weight.
Libido decreases
"Dear, I'm too tired" is not just a phrase, but a real problem of people who sleep too little. The amount of hormones that stimulate sexual desire is 15 percent lower in people who sleep less than 5 hours a day.
You are more prone to diseases
Lack of sleep also affects the immune system. More precisely, it reduces its ability to react and respond to infections. Because of this, sleep-deprived people will be the first to pick up any bacteria or viruses, and it will take them much longer to recover.
