What is the risk of lack of sleep? Somnologist answers
Insomnia, sleep disturbances, and simply not having enough time to get to bed are a common problem in modern society. What is the risk for your body, says the doctor Osteo Polu Сlinic somnologist, neurologist Olga Ivanovna Begasheva .
Almost every person the next day after a sleepless night feels tired, decreased mood, agility and speed, and especially memory and concentration. If these feelings do not arise, you are really lucky.
People who do hard work experience the most problems. A weightlifter can regain his performance in 4 hours of sleep, and a chess player shouldn't play a game at all if he slept poorly or little.
What sleep disorders depend on
Systolic pressure depends on the duration of sleep. It is easy to determine the likelihood of the risk of cardiovascular disease and high blood pressure.
Insomnia can be of three types :
Sleep disorders occur in people of different professions and ages. The first rehearsals of insomnia are found at school age. As for professional athletes, most often sleep disturbances occur in representatives of aesthetic sports, then in contact ones, less often in team athletes and archers, as well as in race car drivers or tennis players.
those who face high levels of risk, such as rock climbers. This fact can be explained by the fact that people involved in dangerous sports live consciously, monitor themselves and their sleep schedule. In contact sports, high loads with overstrain of the psycho-emotional sphere through the release of cortisol negatively affect sleep.
What affects the quality of sleep
Immunity and memory depend on the quality of sleep. In a dream, the body is restored. In the slow stage, and this is the deepest sleep in the first third of the night, somatotropic hormone is released - growth hormone with anabolic activity, which is manifested in the improvement of the protein-synthetic functions of the body. Deep sleep is followed by rapid sleep. An abundance of vivid and vivid dreams is often found with insomnia. It is most difficult for those overwhelmed by anxiety, in which case it becomes difficult to fall asleep. With depression, early awakenings are noted.
What happens from lack of sleep
If you have not managed to sleep at night and during the next day, nothing special will happen, provided that sleep after this is sufficientaccurate and regular. This approach is sometimes used in the treatment of people with mild depression. This technique is called sleep deprivation (sleep deprivation) and allows you to get more sleep after you skip a night. But if such violations are of a long and regular nature and, moreover, are accompanied by difficulty in breathing, metabolic syndrome occurs. In this case, a person's sleep can be compared to the labor of a miner in a mine to overcome respiratory disorders. In the morning, blood pressure may rise, over the years, tissue resistance to insulin increases, there is a risk of diabetes mellitus, obesity and early vascular atherosclerosis are formed. To correct the situation, CPAP therapy is used to create constant positive pressure in the upper respiratory tract, which prevents the walls of the pharynx from collapsing during sleep.
If a person is forced to work intensively and not sleep for several nights, in rare cases, a single generalized convulsive seizure, which then does not recur. There is a serious illness called agrypnia - painful insomnia. Basically, patients with mental disorders and patients with alcoholism in the last stage suffer from this disease. The duration of such insomnia can be counted in days - hallucinations, fears, nightmares, delusional ideas appear, connection with reality is lost.

What happens if you stay awake for several days?
The record for insomnia belongs to Rand Gardner, who was awake for 264 hours and 30 minutes, which is 11 days. After 1963, when this experiment led to severe mental damage to the subject, such tests were forbidden.
Nerve cells need sleep, the brain must free itself of waste products, accumulate neurotransmitters, develop a plan of action for the future, remember images day. The body needs rest. It has been proven that among flight attendants and nurses working on night shifts, cases of cancer are more common.
Day without sleep. Feeling of tension, nervousness, anxiety. Physical and mental fatigue in the afternoon. Due to the release of stress hormones, mainly cortisol, blood pressure can rise. Efficiency remains.
Two days without sleep. Impaired concentration of attention, marked physical and mental fatigue. Depletion of central nervous system mediators occurs.
Three days without sleep. Possible memory impairment, feeling in space and time, hallucinations. At this stage, changes during a 24-hour sleep can be reversible. However, over-excitement can be difficult to fall asleep. Basal metabolic rate decreases.
Four days without sleep. Internal organs malfunction, maybeexacerbate peptic ulcer or heart disease. Interruptions in the processing of sensitive impulses, in addition to hallucinations, delusional ideas may arise that require urgent medical correction.
Five days without sleep. There is a violation of the exchange of neurotransmitters in the parietal, temporal and frontal areas, intracerebral connections go astray. At this stage, the changes may be irreversible. Speech is impaired, a person does not recognize the image of an object and can take a road sign for a person, all types of memory and thinking are affected.
Every person needs high-quality, full and sufficient sleep. A somnologist is responsible for the diagnosis and treatment of disorders. It is necessary to establish the correct diagnosis, conduct a full study and start treatment on time.
