Sleep deficiency, which poses a serious threat to mental and physical health, cannot be corrected in one strong rest night. According to the research, sleep deficits are difficult to compensate for even young people. Sleep duration affects cognitive functions, such as memory and speed of mental analysis, which are not restored as quickly as other aspects.
It is known that chronic lack of sleep has a negative effect on concentration, learning, creativity, solutions to problems and decision making. Observations show that one night without proper sleep can affect brain function as well as a high concentration of alcohol in the blood.
Given the high risk of developing various diseases, from cardiovascular disease to dementia, experts emphasize the importance of avoiding lack of sleep. Usually, from 7 to 10 hours of sleep every night is considered the norm depending on the age of the person.
Measures to improve sleep quality include proper nutrition, physical activity, sleep and other hygienic approaches. A clear problem is "pandemic insomnia", which can be overcome by training and forming new useful habits.
