A third of a person’s life is spent in a dream, which means that it is extremely important for health. For decades, psychologists and neuropathologists have been studying sleep and its impact on well-being and performance. Currently, due to the fast pace of life, stress, and hard work, the problem of lack of sleep is particularly acute. The importance of sleep is determined by the fact that it helps the human body deal with stress and resists the occurrence of mental disorders.
An important component of human homeostasis is sleep. There is a certain physiological cyclicity of neuroendocrine and vegetative changes during sleep. The growth of adrenocorticotropic hormone in the morning is a decisive factor in the regulation of sleep termination. Under stress, there is a change in the activity of the hypothalamus and disturbances in the regulation of sleep. Sleep disorders are closely related to stressful events and are often the first symptoms of stress. And although insomnia under stress is usually transient and persists for several days (physiological insomnia), chronic insomnia caused by distress is a big problem. In situations where the body is forced to adapt to constantly changing conditions, sleep disorders, especially chronic ones, deplete adaptive mechanisms and do not allow adequate adaptation, thereby exacerbating the negative impact of stress.
Good sleep largely determines a person’s resistance to long-term stress and stress. Currently, it is the adaptive (anti-stress) sleep system that determines the degree of resistance of the body to various stresses. Its capabilities make it possible to optimize the body’s adaptation to the environment during sleep and partly determine stress resistance in general. The peculiarity of this system is that it actively works during the entire sleep time, even in the absence of a stressor.
Lack of sleep also leads to severe depression, destroys a person’s psyche, and worsens his mental well-being. The most common mental consequences of sleep disorders are irritability or depression. At the physiological level, certain neurotransmitters in the brain are responsible for a balanced state and mood. Systematic non-precipitation leads to their exhaustion. As a result, a person becomes irritable and anxious, or vice versa, experiences a depressed state, a feeling of emptiness, meaninglessness, and hopelessness. These symptoms are signs of depression, which can be caused by a lack of sleep.
In addition, patients with sleep deprivation often have reduced attention and the ability to concentrate. It becomes difficult for them to control their thoughts, emotions, and sometimes actions. With a lack of sleep, there are difficulties with productivity and productivity, and even in the activity that a person loves and which has always brought them pleasure (Jones et al., 2018). A lack of sleep does not allow the psyche and nervous system to fully recover. As a result, there is a completely natural imbalance in the work of the departments of the nervous system. Therefore, with a lack of sleep, a person may experience anxiety and even panic attacks. ⠀
Not only the quality but also the duration of a person’s life depends on the duration of sleep. Chronic lack of sleep has a negative effect on the body and contributes to the development of serious diseases. For example, lack of sleep reduces stress resistance and increases the likelihood of getting depression or other mental illnesses. Therefore, in order to avoid serious health problems, it is necessary to adhere to a healthy sleep regime.
