Insomnia is a subjectively unsatisfactory condition for a person when he has trouble sleeping for a long time. Recognizing insomnia is simple: just see if you feel bad after you wake up or not.
Insomnia can manifest itself in different ways: someone tossing and turning in bed for hours, as a result, manages to catch a short sleep shortly before the alarm goes off, some have several wakings per night, after which you can no longer fall asleep. There is only one result - a person gets up broken, lost, tired.
Do not underestimate the scale of the problem: not only did you not get enough sleep, your body did not recover. There are many studies on how sleep problems affect our health. Lack of sleep leads to constant stress, disruption of the brain, poor immunity, cardiovascular disease, hormonal disorders.
A somnologist works with the physiological causes of sleep disturbance (apnea, hormonal disruptions, menopause, and others). But most often, insomnia occurs on the basis of psychological problems, chronic stress, depression. Therefore, the help of a psychotherapist is needed here.
