Often people do not understand why it is harmful to sleep for a long time. But prolonged sleep is not always harmless. If a person sleeps a lot and, in addition, suffers from daytime sleepiness, it is just not oversleep at all, it can serve as a symptom of dangerous diseases.
Prolonged night sleep
Doctors speak about harm of lack of sleep. Because of it in the body, metabolism is disrupted, some diseases develop and other unpleasant consequences are manifested.
But is it harmful for a person to sleep much? Of course, we all know that a healthy sleep in a child or teenager is the key to his well-being. Some people think that this is useful at any age. But for a complete rest the body of an adult person requires no more than 7-9 hours of sleep. The rest of the time is excessive.
Why do people tend to sleep a lot?
A healthy sleep in an adult lasts an average of 8 hours. Deviations in the greater or lesser side are an individual feature. The indicators depend on the amount of time for which the body is restored. Even some people ask the doctor ‘why can’t i stop sleeping’?
If a mature or elderly person needs more than 8-9 hours to sleep, doctors call this condition hypersomnia. It manifests itself in the great duration of night rest, and in constant daytime sleepiness. A painful condition can lead a person to the point that he falls asleep at the most inopportune moments. Let’s find out why this happens and it’s harmful to sleep for a long time.
Sleep regulation is a complex system that exerts a retarding or activating effect on the central nervous system. Participation in this takes the cerebral cortex, subcortical, limbic and reticular structures. Failure in this process and causes hypersomnia.
The causes of hypersomnia often become:
- Prolonged lack of sleep;
- Physical and psychological stress;
- Recently transferred stress;
- Treatment with specific medications, including antipsychotics, tranquilizers, antihypertensives, diabetes medications, etc .;
- Craniocerebral trauma causing posttraumatic hypersomnia;
- Cancers of the brain;
- Violation of the cardiovascular system;
- Mental disorders;
- Problems with the thyroid gland;
- Somatic diseases;
- Acute lack of vitamins and trace elements, especially vitamin D, iron, iodine
Sometimes the cause cannot be found, since the increased duration of sleep is not associated with any disease. This condition is called idiopathic hypersomnia.
Symptoms of hypersomnia
The main sign of hypersomnia is the long duration of night sleep (about 12-14 hours), which is accompanied by constant drowsiness and lethargy throughout the following day.
The people suffering from it have a difficult awakening, it is difficult for them even to tear themselves away from the pillow, there is not enough energy to get out of bed on an alarm clock. And after the end of sleep, these patients for a long time are in a braked state. They look as if they are sleeping further. In the people, this condition is called “drunken sleep.”
It’s hard to get out of bed
Various forms of this disease cause permanent or periodic daytime sleepiness. Such a state negatively affects a person’s working capacity and his attentiveness. Hypersomnia beats down the rhythm of life and sometimes forces the patient to take breaks during the day. Some people feel relieved after a day’s sleep, but more often drowsiness persists after it
