Introduction
In general, constant drowsiness may be caused by factors such as insufficient sleep, excessive fatigue, anemia, obstructive sleep apnea-hypopnea syndrome, or hypothyroidism, and requires symptomatic management through general treatments, medication, and other methods. It is recommended to engage in appropriate daily exercise, such as jogging or swimming, which can help enhance cardiopulmonary function and boost physical vitality.
In general, persistent drowsiness may be caused by insufficient sleep, excessive fatigue, anemia, obstructive sleep apnea hypopnea syndrome, hypothyroidism, and other factors. Symptomatic management through general treatments, medications, and other methods is necessary. If discomfort occurs, it is recommended to seek medical attention promptly and undergo appropriate treatment under a doctor's guidance. Detailed explanations are as follows:
1. Insufficient Sleep
Factors such as long-term late nights, sleep disorders, or changes in the sleep environment may lead to insufficient sleep, preventing the nervous system from effective regulation, thereby causing somnolence. This may be accompanied by symptoms like chest tightness, mental abnormalities, and difficulty concentrating. It is recommended to maintain a regular sleep schedule, avoid caffeine-containing beverages before bedtime, and create a quiet and comfortable sleeping environment.
2. Excessive Fatigue
Excessive physical or mental labor consumes significant energy, potentially leading to muscle and nervous system fatigue. The body's physiological need for sleep increases, resulting in excessive sleepiness, often accompanied by symptoms such as limb soreness and fatigue. It is recommended to rest adequately in daily life and avoid prolonged work or activities.
3. Anemia
Malnutrition, excessive blood loss, or impaired hematopoietic function can cause anemia. In anemia, the blood's ability to carry oxygen is reduced, preventing tissues and organs from receiving sufficient oxygen, leading to insufficient energy production and causing fatigue and drowsiness. Symptoms may also include pallor, palpitations, dyspnea, and dizziness. It is recommended to take medications such as ferrous sulfate sustained-release tablets, ferrous fumarate tablets, and ammonium ferric citrate vitamin B1 syrup II under medical guidance.
4. Obstructive Sleep Apnea Hypopnea Syndrome
Collapse or blockage of soft tissues in the upper airway during sleep may lead to obstructive sleep apnea hypopnea syndrome. During sleep, the airway is partially or completely blocked, causing brief episodes of breathing cessation, which leads to hypoxia and micro-arousals, disrupting the normal sleep cycle and causing excessive daytime sleepiness. Patients may also experience symptoms such as snoring, nocturnal polyuria, and headaches. It is recommended to take medications such as atorvastatin calcium tablets, acetazolamide tablets, and salbutamol inhalation aerosol under medical guidance.
5. Hypothyroidism
Autoimmune damage, excessive or insufficient iodine intake, and other factors can lead to hypothyroidism. In hypothyroidism, insufficient thyroid hormone secretion reduces nervous system excitability, causing somnolence. Symptoms may include fatigue, weight gain, constipation, and dry skin. It is recommended to take medications such as levothyroxine sodium tablets, thyroid tablets, and alfacalcidol soft capsules under medical guidance.
It is recommended to engage in appropriate physical exercise in daily life, such as jogging or swimming, which helps enhance cardiopulmonary function and improve overall vitality.
