One of the essential needs of any person is a full-fledged sleep, which not only gives rest to the body, but also ensures the stable operation of the nervous system that regulates all body processes. With frequent insomnia or inadequate, poor-quality sleep, the body does not have time to fully relax and recuperate, and the nervous system is in a constantly overloaded state. Due to the lack of rest, working capacity and emotions can suffer, memory is gradually impaired and mental abilities are suppressed, immunity can decrease, and even excess weight comes on. How does this happen? How much sleep do you need to not get sick?
Sleep as a necessity?
A person cannot be awake for a long time, both children and adults need a good rest, although with age the need for sleep decreases. In order to maintain daily working capacity, full-fledged mental abilities and good mood, not to suffer from various diseases, you need a full and high-quality sleep. But what is a good dream? This is, first of all, the duration of sleep for at least 7–8 hours, while the night’s rest itself must be of high quality. That is, when going to bed, a person falls asleep quickly and soundly, wakes up easily in the morning and feels kind and rested, during the night he does not wake up at every rustle, and does not interrupt sleep by constant trips to the toilet, drink or any other needs. In this case, we can say that a person has no problems with sleep. If a permanent lack of sleep is formed or insomnia haunts, this threatens with health problems and a decrease in efficiency, and if the patient is engaged in potentially dangerous types of work or driving a car, sleep problems can turn into tragedies.
Negative emotions, irritation as a result of lack of sleep
Sleep deprivation is a serious problem for both physical and mental health. With constant lack of sleep, various diseases arise: cardiovascular pathologies, metabolic disorders, up to diabetes mellitus, and even excess weight are provoked. But often our emotions and general condition speak of a lack of sleep, and a person can not always immediately understand that he lacks full sleep. If people fall asleep on the go, in the most inappropriate places for this, simply turning off, this is already an extreme degree of the problem. Usually our body begins to give signals long before major breakdowns occur, and tragedies happen due to falling asleep in the wrong place or at the wrong time.
So, a person who sleeps little usually experiences negative emotions for any reason, literally everything upsets or annoys him. He does not hold back emotions well, is quick-tempered and irritable, his actions may not be logically explained, and the level of excitement may be too high. The body needs a good rest, if it does not get it, and it has much more activity than periods of rest, then the body and nervous system begin to give alarm signals that something is wrong. Therefore, emotions can get out of control, and a person behaves inconsistently with the situation.
Overweight due to insomnia
Often, patients associate the appearance of excess weight with the fact that they move little, they have a sedentary job, and in the evening they eat tightly. This is true, but sleep problems in mass gain are also to blame, although many are not inclined to draw parallels between the quality of sleep, being overweight, and also waking up literally “wolf” appetite. Meanwhile, experts in the field of nutrition and metabolic processes say that with chronic lack of sleep, the body turns on the mode of saving energy reserves. He has nowhere to get energy from, except to use food, so he begins to actively awaken his appetite and, against the backdrop of stress, which is insomnia for the body, consumes the food received extremely sparingly, forming excess weight and spare fat deposits. Often, in order to fall asleep, the body literally requires sweets and high-calorie foods, and sleep does not go without a bun or bun at night. Accordingly, if excess weight appears against the background of poor sleep and increased appetite, it’s time to relax and sleep well, and then start losing weight.
Memory problems and sleep
Often, people suffering from chronic insomnia may also suffer from memory, which is associated with the depletion of the entire nervous system as a whole. If memory lapses began to be observed, a person forgets what he did a few minutes or hours ago, you should think about rest and sleep. In a similar way, it is worth doing if you forget — where and why you went, what time an important meeting is, and much more. This is due to quite understandable processes: the body supports the work of vital organs and systems during a period of stress, turning off all secondary activities. And lack of sleep is a serious stress, so memory is also temporarily turned off. To improve your memory and get in shape, you should review your schedule and include extra time for rest and sleep.
Decreased immunity: is sleep also to blame?
Often, patients tend to attribute frequent colds to the influence of environmental factors, stress and weak immunity. At the same time, they do not associate this condition with insomnia or a deterioration in the quality of sleep, although it is the violation of proper rest for the body that is one of the key factors in reducing local or systemic immunity. Constant lack of sleep leads to inhibition of antiviral protection, and can also lead to the fact that dormant foci of microbial infection “wake up”. The nervous system in a tired state monitors the general mechanisms of the body’s defense, not significantly penetrating into the mechanisms of immunity, counting on the fact that the immune forces are enough. But when the reserves are depleted due to the stress caused by lack of sleep, the immune system cannot fully cope with the problems, which makes patients defenseless against various infections. Therefore, if a cold occurs several times in a row with a short break, and a sore throat has become a frequent companion, it is important not only to see a doctor, but also to get enough sleep.
