What causes constant drowsiness and the urge to sleep all the time?

Generally speaking, persistent drowsiness and excessive daytime sleepiness may be caused by unhealthy lifestyle habits, poor dietary habits, depression, hypothyroidism, or obstructive sleep apnea hypopnea syndrome. If experiencing discomfort, timely medical consultation is recommended. Detailed explanations are as follows:

1. Unhealthy Lifestyle Habits

Unhealthy lifestyle habits, such as excessive use of electronic devices at night, irregular sleep schedules, or lack of physical activity, can all lead to fatigue and drowsiness during the day. Adjusting lifestyle habits promptly, reducing evening screen time, and ensuring adequate sleep are recommended.

2. Poor Dietary Habits

Excessive intake of high-sugar and high-fat foods, or an unbalanced diet, may also result in daytime drowsiness. It is important to improve dietary structure by reducing consumption of high-sugar and high-fat foods while increasing the proportion of vegetables, fruits, and whole grains.

3. Depression

Depression is a mental disorder characterized primarily by persistent and prolonged low mood. Patients often exhibit symptoms such as hypersomnia, low mood, and reduced interest. Under the guidance of a qualified physician, pharmacological treatments such as paroxetine hydrochloride tablets, bupropion hydrochloride tablets, and clomipramine hydrochloride tablets may be used, along with psychotherapy.

4. Hypothyroidism

Hypothyroidism may be caused by autoimmune diseases, thyroid surgery, or radioactive iodine therapy. A deficiency of thyroid hormones leads to a decreased metabolic rate and insufficient energy production, resulting in fatigue and excessive daytime sleepiness. Other possible symptoms include weight gain and cold intolerance. Treatment under a physician's guidance may include medications such as levothyroxine sodium tablets, thyroid extract tablets, and vitamin D3 capsules.

5. Obstructive Sleep Apnea Hypopnea Syndrome

Obstructive sleep apnea hypopnea syndrome is associated with factors such as obesity, aging, smoking, and alcohol consumption. During sleep, partial or complete collapse of the upper airway occurs, leading to episodes of apnea or hypopnea, which disrupt sleep quality and cause daytime drowsiness. Symptoms may include snoring and waking up gasping for air during the night. Under medical guidance, treatment options may include Xiangju capsules, Tongqiao Biyan tablets, and oxymetazoline hydrochloride nasal spray.

Maintaining a regular sleep schedule, balancing work and rest appropriately, eating a balanced diet, and engaging in moderate physical activity are recommended in daily life.
