Drowsiness and fatigue are two different concepts.
A sleepy person struggles to stay awake and keep his eyes open.
Fatigue can also be felt when the person is awake and does not feel sleep.
Children, adults and the elderly often suffer from drowsiness and fatigue due to their lifestyle:
- They eat in the evening after 20 pm and go to bed late.
- They eat foods that interfere with sleep.
- They drink too much stimulating drinks, such as coffee and tea. After consuming these substances, the person has more energy, but when the effect wears off, the organism is more tired than before.
Drowsiness can be dangerous, especially when driving.
Causes of constant daytime sleepiness
Sleep disorders are the main reasons for somnolence.
- Sleep apnea.
These diseases do not allow rest, no matter how long you have been in bed.
During the day, the person concerned is not recovered, but
- feels exhausted,
- has trouble concentrating.
The disturbance of the circadian rhythm (biological clock) can be caused by:
1. night shifts, 2. time difference,
3. change of seasons (spring fatigue is caused by the increase in hours of sunshine),
4. staying up longer.
depression, anxiety, etc. can cause insomnia and thus constant sleepiness during the day.
The affected person feels physically and mentally inactive and, moreover, lacking energy and resigned.
Some conditions can give the feeling of daytime sleepiness, for example:
- hyperthyroidism (hyperthyroidism),
- hypothyroidism (thyroid dysfunction),
- anemia and leukemia,
- kidney diseases,
- heart disease (for example, heart failure),
- liver diseases (for example, cirrhosis),
- Brain damage
- restless leg syndrome (pathology that causes the urge to move during sleep),
- Premenstrual syndrome that occurs a few days after ovulation and menstrual cycle
- lack of vitamin D and B12,
- a malignant tumor in the advanced stage,

- Grippostad (paracetamol + chlorphenamine) for colds,
Pregnancy and excessive sleepiness
During pregnancy, it is largely normal to be sleepy during the day.
Most women suffer from it at the beginning of pregnancy and until about the tenth week.
The cause is the increased hormone level of progesterone in the first trimester.
Causes of insomnia can include:
1. gastroesophageal reflux during the night, 2. frequent nighttime urination,
3. anxiety or stress.
Postprandial fatigue (after eating)
Tiredness and drowsiness after a plentiful dinner are normal.
Type of food:
- Foods such as oatmeal and whole grains are digested over long periods of time, but can satisfy hunger for a few hours. Nevertheless, gluten-containing cereals can cause digestive problems and sleep disorders. Many people who eat pizza in the evening cannot sleep at night.
- In contrast, processed foods, sweets, and refined carbohydrates are immediately digested and absorbed. Since these foods do not contain enough nutrients, their effect is only a temporary supply of energy, followed by exhaustion and drowsiness.
- Wine can cause drowsiness, especially red wine.
Quantity and timing of meals:
Heavy meals can cause drowsiness, especially if they contain processed, fat, and heavy foods, such as meat.
Indigestion can cause:
- stomach pain,
A lunch of fresh fruits, vegetables, legumes and nuts (hazelnuts, walnuts, etc.)
- does not change the energy level,
- does not increase arterial blood pressure,
- does not increase the heartbeat (tachycardia).
It is recommended to divide the food into five or six small meals a day.
Many people think that they should have a sumptuous breakfast in the morning, but it would be better to drink a glass of lemonade in the morning and postpone breakfast until the morning. The human body is programmed to perform bodily functions at set times.
- At night, during sleep, the body assimilates the foods that were ingested during the day.
- In the morning, the body is programmed by the bowel movement for excretion, because the colon then runs at full speed. Citrus fruits and especially lemons can support intestinal activity, an alternative is juicy fruit such as honey and watermelon.
- At noon, the main meal of the day should take place, abundant and rich in proteins. According to hygienism (theory of the ideal way of life), lunch should be the first meal of the day. After 20 o’clock should not be eaten, because the phase of nutrient absorption begins.
Food allergies and intolerances: Tiredness and fatigue can also be caused by some allergies to food, for example:
