What is the definition of drowsiness?
Drowsiness is the desire to sleep, a feeling that usually increases the longer we stay awake.
What is the reason for feeling sleepy?
There are several reasons for feeling drowsy, which are generally indicators of the body’s need for rest or not getting enough sleep.
How does drowsiness happen?
Drowsiness is associated with a buildup of a chemical in the brain called Adenosinewhich accumulate between and within neurons, higher levels of which are associated with higher levels of sleepiness.
- Mild drowsiness in a sitting position and when reading or watching TV.
- Poor focus.
- lack of attention
- Short-term memory problems.
- Suffering from these problems during the day can lead to insomnia at night or poor sleep quality.
- interrupted sleep
- Headache in the morning.
- sleep walking
How does caffeine reduce drowsiness?
Caffeine works by blocking the action of adenosine within the brain, which leads to alertness.
Causes of daytime sleepiness
Not getting enough rest at night leads to drowsiness, according to a report Russian FBI website.
Drink a lot of caffeine
Because a person becomes accustomed to caffeine, and when he does not get it he feels tired and drowsy.
Having sleep apnea (sleep asphyxia)
This condition can occur during sleep and recur partially or completely, and may occur dozens or hundreds of times every hour, and it can lead to loud snoring and waking up due to shortness of breath.
A person may not remember his sleep problems when waking up in the morning, and the poor quality of sleep causes the problem of drowsiness during the day, and the possibility of losing consciousness while driving a car increases for people who suffer from sleep apnea, so they should seek medical help.
Chronic Fatigue Syndrome
This condition causes fatigue and drowsiness, and is characterized by a deterioration in sleep quality after exertion, and is also associated with recurrent pain in the muscles and joints, and scientists have not been able to fully understand the causes of chronic fatigue syndrome.
Also called Sleeping Beauty Syndrome, it affects a person at a young age and leads to repeated cycles of excessive sleepiness, and these cycles may last for a few days, weeks or months, and this syndrome usually affects the student’s school attendance and the responsibilities that he performs daily.
restless leg syndrome
It is a condition characterized by a disturbing feeling in the leg accompanied by a desire to move it, and it usually worsens in the evening at rest. This syndrome is diagnosed through sudden vibrations that occur during sleep that may be repeated and spoil the comfort of the person and those who sleep next to him. Fortunately, there is a treatment for this disease.
Disruption of the circadian rhythm (circadian clock)
There are many disruptions in the daily rhythm of life that may lead to fatigue, as the rhythm of the body clock in normal cases helps to coordinate movements in a regular time frame.
If there are imbalances in this rhythm, a person may feel sleepy at inappropriate and unfamiliar times, and this problem can be treated through the use of the hormone melatonin, for example.
Causes of sleepiness in summer
Why do we feel sleepy with high temperatures?
Physiologists have long revealed that high air temperature makes a person feel tired and want to take a nap, according to a report published by the Russian “Novi Ushag” website by the writer Ekaterina Komissarov.
The writer explained that when the weather is hot we sweat a lot, this is the natural mechanism of thermoregulation, and the brain records an increase in temperature and a severe contraction of the sweat channels begins to absorb moisture from the surrounding tissues and excrete it, then the sweat comes out on the inflamed skin and evaporates and the temperature on the skin decreases.
Besides, the body promotes subcutaneous blood circulation and dilates blood vessels.
The writer shows that in this process of thermoregulation, the body loses moisture intensely, as it is associated with many symptoms that appear on the body, such as weakness, fatigue and drowsiness, and it is also considered evidence that the body lacks fluids.
You spend a lot of energy to cool off
According to the author, the strong work of the sweat glands and the acceleration of blood circulation results in the consumption of a lot of energy, which leads to a person feeling tired and drowsy.
Reduction of Blood pressure
The writer mentioned that the blood vessels expand in the heat, which leads to a decrease in pressure, which means – even if it happens to a small degree – that less blood is transferred to the brain, and this in turn can cause dizziness, weakness and drowsiness.
The writer cautioned that the sudden drop in pressure can be accompanied by fatigue due to heat and heat stroke, so if you suffer from dizziness and nausea – and all this is linked to exposure to heat – look as soon as possible for a shade or a room with air conditioning or another cold place, because you need to cool down and drink water.
Why can’t I sleep despite drowsiness?
The reason for not sleeping despite drowsiness may be anxiety and stress or suffering from psychological pressure.
What is the treatment of persistent drowsiness?
- Get enough sleep.
- If drowsiness is the result of psychological stress, it must be dealt with and consult a doctor or psychiatrist.
- If the drowsiness is the result of another condition, such as restless legs syndrome, it should be treated.
