Why do you want to sleep all the time?

Many of us are sleepy after a hearty lunch, sometimes uncontrollably you want to take a nap for an hour or two under the sound of rain, and sometimes the eyes close themselves while working at the computer or during a boring lecture. Such drowsiness is quite natural, and there is no cause for concern when it happens from time to time. But if you began to notice that you want to sleep all the time, it is time to think about why this happens. Why do you want to sleep all the time? Especially you need to attend to this issue in the case when such a pathological drowsiness has overcome you for quite a long period, and all this time you are not experiencing excessive physical or moral stress.

The main causes of excessive sleepiness

Oxygen starvation

With a long stay in a stuffy unventilated room, a person develops oxygen starvation. The lack of oxygen in the body especially affects the brain tissue.Thus, the performance of the brain decreases, which leads to increased fatigue and drowsiness.


In some people, increased sleepiness may be associated with bad weather. Meteorically dependent people are very sensitive to many adverse weather factors � they are drawn to sleep at low atmospheric pressure, high humidity or during magnetic storms. In addition, the body of many people with drowsiness reacts to a lack of sunlight - they experience drowsiness in late autumn and winter, and with the arrival of spring it goes away by itself.

Chronic stress, fatigue and lack of sleep

These three above-mentioned problems, common to almost every modern person, are most often the cause of increased drowsiness.


Taking certain medications with a side sedative effect may provoke the development of pathological drowsiness.

Avitaminosis and lack of trace elements in the body

Fatigue and excessive sleepiness can be caused by a lack of B vitamins, in particular vitamin B5 (pantothenic acid) and vitamin B6. In addition, drowsiness may be due to deficiency of vitamin D, vitamin P and iodine.

Some diseases

Drowsiness may be a side symptom of some serious illnesses. Drowsiness may be accompanied by iron deficiency anemia, hypotension or hypothyroidism. In addition, pathological drowsiness is the main symptom of such rather rare diseases as narcolepsy or Kleine-Levin syndrome.
