Regardless of the reasons for lack of sleep, the body gets deviations from the standards, which can eventually lead to heart attacks and strokes.
Insomnia is a problem that bothers many because of its repercussions on the health of the body, which was confirmed by Dr. Anton Tikhonovsky, a neurologist, who explained that lack of sleep negatively affects all body systems, and can lead to myocardial infarction and stroke.
Tikhonovsky said in an interview with the newspaper “Gazeta.RU” that one of the consequences of lack of sleep is hallucinations, cardiovascular disease, and so on.
According to him, an adult should sleep for between 7-9 hours a day, and if sleep hours decrease compared to physiological standards even a few hours, it means sleep deprivation.
Lack of sleep
perceptual disturbances
Regardless of the reasons for lack of sleep, the body gets deviations from the standards, which can eventually lead to health disorders such as impaired cognitive functions, decreased performance and emotional disorders, he said.
“The symptoms are initially vague, so many try to ignore them. But after about 17 hours without sleep, the results of intelligence and attention tests are similar to the results of those whose blood has 0.5 ppm of alcohol. And after 72 hours without sleep, the person suffers from hallucinations,” says Tikhonovsky. .
In addition to the memory and concentration problems caused by the decreased sleep duration, the person becomes irritable, and the nervous system does not have enough time to process the impressions and emotions accumulated over the previous day. Inadequate sleep in children leads to symptoms of attention deficit hyperactivity disorder, which disappear when sleep improves.
overweight
The neurologist also pointed out that chronic sleep deprivation becomes a cause of weight gain, because at night several substances that regulate the metabolism process are activated in the body, including ghrelin and leptin, and with a decrease in sleep duration, the concentration of the appetite-stimulating hormone ghrelin increases, in return for this the concentration of the hormone ghrelin decreases. leptin that brakes it.
And he adds: Tissue regeneration processes are active in the body during sleep, and this process depends mainly on the hormone somatostatin, which the body produces during the period of deep sleep, meaning that the low level of this hormone, which is called the growth hormone, leads to poor wound healing and the restoration of health after injuries and exhaustion. physical.
He also pointed out that “the permanent deviation of sleep time from the physiological norm is also a risk factor for the development of metabolic syndrome, which can lead to problems in the heart and blood vessels, including myocardial infarction and stroke.”
The immune system also suffers when the quality of sleep decreases as well. For example, the results of an experiment conducted in 2003, which included examining patients vaccinated against hepatitis, showed that the amount of antibodies in patients who did not sleep the night after vaccination is twice as low compared to patients. who slept well.
