Sleep is an essential component of the physiology of the body, providing the necessary rest for all organs and systems. However, many people neglect to get a full night’s rest — whether it’s for work, personal life, or entertainment. Such a lifestyle adversely affects the state of the body. Constant lack of sleep leads to the development of severe complications that significantly impair the patient’s quality of life.
Lack of sleep significantly affects our body weight. Due to lack of sleep, we feel tired, often feel weak. In the daytime, we have to do a lot of work, which often simply does not have the strength. Therefore, we begin to “seize” overwork with high-calorie foods. With prolonged lack of sleep, the human body begins to accumulate excess weight, which then will be very difficult to lose.
Fast carbohydrates are especially dangerous — buns, cookies, chocolate and confectionery. Without sleep, we try to fill the lack of energy with the help of these products, but instead we get extra pounds. And after work, coming home tired, we try to get rid of the ailment with the help of a plentiful high-calorie dinner. It also contributes to a significant increase in body weight.
Other reasons for the appearance of excess weight with lack of sleep are the following factors:
- increased production of the hunger hormone in a sleepy person;
- slowing down the metabolism in the body, which leads to poor absorption of products;
- increased appetite;
- decreased mood due to low levels of serotonin, which leads to the desire to please yourself with sweet or floury products.
The versatile effect of lack of sleep on metabolism ensures rapid weight gain. With constant lack of sleep, the development of obesity is possible, which often leads to severe complications. Excess weight is a risk factor for the development of diseases such as strokes, heart attacks, hypertension and diabetes. Against the background of obesity, deformities of bones and joints can also occur.
Violation of the heart and blood vessels
Against the background of lack of sleep, blood pressure rises significantly. Physiologically, this process is manifested by narrowing of small peripheral arterioles. Due to the increase in vascular resistance, the load on the heart increases. Its muscle wall begins to work in an enhanced mode, which leads to faster wear of the fibers. Therefore, those people who often lack sleep have a significantly higher risk of developing cardiovascular diseases.
An increase in blood pressure and the development of hypertension also contributes to the appearance of atherosclerosis. It occurs due to the fact that when blood enters the narrowed vessels, their walls receive minor damage. Microtraumas are closed with fatty molecules that restore the integrity of the artery. However, if the lipid balance is disturbed, pathological fatty plaques form in the area of damage. Over time, they can increase and completely block the lumen of the vessels. Because of this, acute circulatory disorders occur in vital organs — heart attacks and strokes, which threaten the life and health of the patient.
Decreased memory and attention
Lack of night rest adversely affects the state of the brain. During sleep, the number of mediators in the nervous system is restored — signal molecules necessary for transmitting information and regulating the functioning of the body. Inadequate sleep leads to the fact that the brain does not have time to replenish the reserve of these molecules.
Due to the lack of mediators, human cognitive functions are impaired. There are disorders of memory and attention. We cannot concentrate on our work, we are constantly distracted by unimportant details, we switch between activities. Any information that we try to remember is absorbed very poorly. It becomes difficult for us to carry out any mathematical calculations, to build logical chains.
In rare cases, with prolonged lack of sleep, a person’s memory may be lost or distorted. He can even forget what he did during the day and where he was. The next day, memories completely drop out or are perceived vaguely, “as if in a fog.” This is due to the fact that during sleep, the brain processes all the events that occurred during the previous day and moves them into long-term memory. Insufficient processing of memories leads to the fact that they are distorted and mixed with each other.
Absent-mindedness, reduced memory significantly interferes with the work or study of a person. Therefore, a full-fledged sleep is so important, which provides the patient with a productive working day.
What else affects poor sleep?
Lack of sleep affects almost all organs and systems of the body. Other negative effects of lack of sleep include:
- decreased immune activity and increased susceptibility to infectious diseases;
- the appearance of psychological changes — irritability, apathy, bad mood;
- deterioration of the skin, nails and hair;
- hormonal changes in the body;
- constant psycho-emotional stress;
- depressive episodes;
- increased risk of developing type 2 diabetes;
- decreased adaptation to physical activity;
- violation of sexual desire.
These disorders may develop gradually. For a long time, a sleep deprived person feels good, but it must be borne in mind that during this period he spends the internal reserves of his body. After some time, symptoms of overwork inevitably occur, which prevent a person from working fully. This is why getting enough sleep every day is so important.
For a good rest, an adult needs at least 7 hours of sleep. At the same time, it is desirable to establish a single daily routine. Going to bed and waking up should be at the same time. So the body will recover better. Normalization of the daily routine is one of the main components of the prevention of serious diseases that can appear against the background of lack of sleep.
