Sleep is as much a human need as food and water. If you give it up completely or reduce its duration to a few hours, then in 4-5 days you will have serious health problems. Even replacing night sleep with day sleep for those who have to work around the clock is detrimental. The lack of adequate sleep leads to endocrine disorders, diseases of the cardiovascular and digestive systems, nervous and mental illnesses. Therefore, insomnia, or insomnia, a disease in which the process of falling asleep or sleep itself is disturbed, is also detrimental to health.
