Problems connected with sleep


Every human being needs to sleep to the same extent as to eat and drink. It is one of the most important human’s physiological processes that is why we devote one third of our lifetime to it.

While sleeping, our body and mind is not just resting from a hard and intense day behind, but it is restoring organism’s processes that are exhausted during a day for it to be ready to welcome the next day. Our mind does not stop at night either. It is almost as active as it is when we are wakeful, although our body is immovable. It is occupied with arranging the information we have got during the day (that is why it is easier for us to cope with a difficult situation in the morning – we see it clearer and it may not seem to us as difficult as we think it was yesterday). According to some scientists’ point of view, it is the reason why we see dreams. Also, a sound nocturnal sleep strengthens our immune system and promotes metabolism processes (if a person has a sleep disorder, he/she may gain or lose weight drastically).

So, if a man doesn’t keep to a sleep schedule for some reasons (goes to bed very late, sleeps less than he/she needs), then he/she should be ready to face the consequences of sleep deprivation:

How does it work?

A person cannot fall asleep or has a disturbed night sleep for a day, two, a week or even months (in the last case, a person can even die). Sometimes, such people do not have another choice but to stand these tortures on their own because a behavioral and pharmacological treatment does not always help. How do you think, is there anything they can still be interested in? I doubt. There might be the only one thought on their minds: What can help me to fall asleep? What can help me to fall asleep? It is so overwhelming that it must not leave space for any other thoughts. Consequently, there appear problems at work because the thoughts are confused; a concentration level is low; initiative is absent. A person can become depressed and indifferent towards anything and anyone because he/she has hung a head down that he/she would never overcome this disorder. Eventually, the relationships with friends, relatives and beloved can be ruined.

As you see, sleep disorders can totally ruin our lives. The worst thing is that there nothing can be done about this in some cases… It is unbelievable, but in the 21st century this area is still to be investigated. At that point, there is no medication for most illnesses concerning sleep problems.

According to the statistics, about 20% of the planet’s adult population suffers from sleep disorders of different kinds. It refers to elderly people more frequently because they may have these disorders as the side effects of age-related diseases.

All existing sleep disorders belong to three main groups:

  1. Dyssomnias.

  2. Parasomnias.

  3. Sleeping sicknesses.

Dyssomnias are sleeping disorders which are characterized by particular difficulties when a man is trying to fall asleep, during the night (a man’s sleep can be disturbed; a man can wake up several times per night and have troubles with immersing into a sleep again; etc.) and when it is time to wake up.

To dyssomnias refer such disorders as (this is not the whole list):

Parasomnias are sleeping disorders which symptoms are shown by unnatural movements, emotions and perceptions while a man is sleeping.

To this category refer:

Sleeping sickness is the one which is caused by external organisms and does not depend on us in most cases. For example, a Tsetse fly infection. The first symptoms are fever, headache, joints pains and itchiness which are usually shown in three weeks after a bite. Then (in a month) come a disturbed sleep, poor movements’ coordination and concentration, rambling speech and thoughts, numbness, etc.

All these disorders can be treated in two ways: either with behavioral and cognitive treatment or pharmacological. The first one stands for changing a person’s sleep hygiene without any medicine. The second one implies prescription of some medicaments which will help him/her to be more relaxed. Taking into consideration the world experience, none of the ways is 100 per cent effective. It emphasizes the importance of keeping a healthy lifestyle and avoiding stress.
