Daytime sleepiness – an alarming symptom?

During the day, the man is awake, and at night he sleeps. It has been a tradition since ancient times. And it is in this mode that the human biological clock works. But sometimes people experience daytime sleepiness. This condition interferes with the working or educational process, causes deterioration of health, and sometimes completely changes the plans. What can daytime sleepiness signal? And when does a symptom require special attention?

Drowsiness, which is considered normal
Everyday person periodically faces daytime sleepiness. If this condition appears rarely, then there is no cause for alarm. Attention requires constant yawning and a desire to sleep, which appear with enviable regularity.

To normal physiological phenomenon include drowsiness during the day, caused by the following reasons:

reception of a full lunch;
cloudy, rainy day;
stuffiness in the room;
too hot day;
insufficient lighting in the room;
gestation period;
wrong sleep mode (later falling asleep);
long journeys, flights;
physical, psycho-emotional, mental stress;
lack of sleep;
medication, accompanied by drowsiness (antihypertensive drugs, some antiallergic drugs, antipsychotics, tranquilizers).
Daytime sleepiness
Such factors cause temporary sleepiness. As soon as the cause is eliminated, the person’s condition quickly normalizes and unpleasant yawning no longer appears.
When sleepiness becomes an alarm
If a person sleeps at least 7-8 hours at night, but at the same time he is tormented by constant drowsiness, then the causes of such a state are often hidden in the pathologies occurring in the body. Independently diagnose such diseases is very difficult, because a strong desire to fall asleep occurs with many disorders.

Main reasons

According to medical research, sleepiness is most often caused by:

1. Depression, nervous exhaustion

Long-term stresses, starvation, excessive loads, prolonged chronic diseases lead to such conditions. The patient complains not only about drowsiness, but also about the appearance of:

constant fatigue;
memory impairment;
decrease in thought processes.
2. Diabetes

In humans, insulin is not properly synthesized or absorbed by the tissues. This leads to a decrease in energy in the cells. Such a process is reflected in the work of many systems. If the cause of increased drowsiness is caused by diabetes, then the patient may experience the following symptoms:

With diabetes mellitus, there is always a feeling of thirst and drowsiness.
feeling weak, tired;
intense thirst;
itchy skin;
increased amount of urine;
smell of acetone from the mouth;
pressure drop.
3. Obese

Obese people often experience apnea. This is a pathological condition in which breathing stops during sleep. It manifests apnea in the form of a short interruption of snoring. To restore breathing, the brain has to wake up and run all the mechanisms. Such awakenings can occur several times during the night. Against the background of poor-quality sleep, a person is confronted with daytime sleepiness.

Additional reasons

The following reasons may cause severe sleepiness:

head injuries;
blood diseases (leukemia, anemia);
traumatic brain injury (TBI);
rehabilitation after illness, injury;
hypotension, hypertension;
restless legs syndrome;
vegetovascular dystonia (VVD);
heart disease;
physical exhaustion;
vascular atherosclerosis;
infectious processes;
insufficient thyroid function;
kidney diseases (glomerulonephritis, pyelonephritis, hydronephrosis);
latent allergies;
internal bleeding;
liver diseases (cirrhosis, chronic hepatitis);
malignant tumors;
hormonal disorders;
intoxication of the body.
During menopause, women experience drowsiness.
Women may experience increased drowsiness during menopause. This phenomenon is caused by the failure of hormones. And in men, hypoandrogenism (lack of testosterone in the body) may underlie fatigue and chronic yawning.
Drowsiness – a sign of dangerous conditions
The following states deserve special attention:

acute intoxication (taking opiates, botulism);
hypothermia (body cooling and freezing);
TBI (brain edema, hematoma);
pre-eclampsia of pregnant women;
severe forms of internal poisoning (hepatic or renal coma).
If, against the background of such pathologies, drowsiness suddenly appears, then it is a symptom of an approaching catastrophe. Such a symptom may indicate severe brain damage.
In such conditions, excessive sleepiness may be accompanied by the following symptoms:

severe dizziness (may indicate brain hypoxia);
increased or slowed heartbeat;
nausea, vomiting (appears in case of poisoning);
pressure increase;
blurred vision and the appearance of “flies” before the eyes (observed in pre-eclampsia);
sharp pressure drop;
loss of consciousness.
In these cases, you should immediately contact the doctors for help.
