The science of sleep strongly recommends that everyone maintained a sufficient level of nightly rest during their lives in order to enjoy the allotted time in full and not go into another world before it’s prescribed. Unfortunately, sometimes only desire to sleep is not enough.
Insomnia is an extremely indiscriminate and widespread disorder of sleep that occurs in people of all ages. Characterized by insufficient duration and/or poor quality of sleep, it occurs on a regular basis for a long time (from three times a week for a month or two).
- Restless legs syndrome
RLS is a neurological disease characterized by unpleasant sensations in the legs and manifests itself in a calm state, usually in the evening and night. It occurs in all age groups, but mainly in middle-aged and older people, and 1.5 times more often in women.
- Behavioral sleep disorder phase
It represents a malfunction in the functioning of the central nervous system and is expressed in the physical activity of the sleeper during the fast sleep phase. In behavioral disorder, the human body acquires an abnormal “freedom” of movement. In 90% of cases, the disease affects men, mostly after 50 years, although there have been cases with nine-year-old patients. A rare disease that occurs in 0.5% of the world’s population.
- Apnea in a dream
It is nothing more than a stop of respiratory movements with a short-term cessation of ventilation of the lungs. Sleep disorder itself does not threaten life, but it can cause other serious illnesses, such as hypertension, coronary heart disease, stroke, pulmonary hypertension, obesity.
It is a disease of the nervous system, related to hypersomnia, which is characterized by recurring episodes of excessive daytime sleepiness. Narcolepsy is very rare, mostly affects young men.
The disease is characterized by the physical activity of a person while he or she is in a state of sleep. From the side, sleeping can seem quite harmless, because a sleeper can do the most usual household chores: cleaning, watching TV, listening to music, drawing, brushing his or her teeth. However, in certain cases, a sleepwalker can harm his or her health or commit violence against a person who has been accidentally met. The eyes of somnambulists are usually open, it is able to navigate in space, answer simple questions, but its actions are still unconscious. Waking up, the lunatic does not remember the nightly adventures.
It is expressed by grinding or tapping with teeth during sleep. The duration of an attack can be measured in minutes and repeated several times a night. Sometimes the sound is so strong that it begins to cause discomfort to the surrounding people. But much more harm bruxism does to the sleeper him or herself: the person is aggravated by problems with tooth enamel, gums, and jaw joints.
- Night terrors and nightmares
Night terrors come in a deep phase of sleep, during which there are almost no dreams, so a person wakes up from a sense of desperation and a sense of catastrophe, but can’t describe a detailed picture of events.
Nightmares also occur in the phase of fast sleep, during which dreams occur.
