Quality sleep is the cornerstone of good health. However, many people feel constantly tired and wonder: why do I want to sleep all the time? The reasons are not always related only to insufficient sleep, but also to other factors, such as lifestyle, hormonal changes, or even underlying diseases.
Drowsiness during the day can be due to many factors. Below you will find the most common causes:
Insufficient sleep is the main cause of fatigue. Adults need at least 7-9 hours of sleep to function properly. Sleep deprivation disrupts hormones (e.g., cortisol, thyroid hormones), leading to fatigue and reduced concentration.
Lack of a balanced diet, exercise, and proper routine can make you feel exhausted.
Reduced water intake causes lack of energy and drowsiness.
Lack of physical activity is linked to poor sleep quality and fatigue.
Overtraining exhausts the body and prevents recovery during sleep.
Working shifts disrupts the circadian rhythm and affects sleep quality.
Although caffeine offers temporary alertness, it negatively affects sleep.
Psychological factors often prevent the onset and maintenance of sleep.
During pregnancy, puberty, or menopause, intense fatigue and insomnia are observed.
From COVID-19 to a simple flu, many diseases cause prolonged fatigue.
Anxiolytics, antidepressants, antihistamines, and antihypertensives may cause drowsiness.
Conditions such as sleep apnea, diabetes, thyroid disorders, chronic fatigue syndrome, autoimmune diseases can cause constant fatigue.
Delayed/advanced sleep phase syndrome, narcolepsy, and other disorders cause uncontrollable drowsiness.

If drowsiness is persistent and affects daily life, it is important to consult a doctor. Blood tests or referral to a sleep specialist may be needed to identify the cause.
