Introduction
Feeling constantly drowsy and as if not getting enough sleep may be caused by physiological factors, or pathological conditions such as high blood pressure or insufficient cerebral blood supply. It can be treated through general management and medication. This condition usually results from excessive fatigue, prolonged熬夜 (staying up late), or excessive mental stress, which keep brain tissue in a state of continuous neural excitation, leading to dizziness.
Feeling constantly drowsy and as if sleep is insufficient may be caused by physiological factors, or it could result from pathological conditions such as hypertension or insufficient cerebral blood supply. Treatment can be carried out through general management or medication. Specific details are as follows:
I. Physiological Factors
This is usually due to excessive fatigue, prolonged熬夜 (staying up late), or high levels of mental stress. These factors keep brain tissue in a continuous state of neural excitation, consuming large amounts of oxygen and leading to symptoms such as dizziness and a feeling of head fullness. It is important to get adequate rest and avoid overexertion.
II. Pathological Factors
1. Hypertension
Chronic hypertension can disrupt the normal dilation and constriction functions of cerebral blood vessels, causing symptoms such as dizziness and blurred vision. Medications such as nifedipine controlled-release tablets or amlodipine besylate tablets may be taken as directed by a physician.
2. Insufficient Cerebral Blood Supply
When cerebral arteriosclerosis or cervical spondylosis occurs, it may lead to impaired cerebral circulation, resulting in ischemia and hypoxia of brain tissue and affecting brain function, which can cause symptoms like headache and nausea. Medications such as flunarizine hydrochloride capsules or betahistine hydrochloride tablets may be used under medical guidance.
In addition to the above causes, persistent drowsiness and fatigue could also be due to cerebral hypoxia, cerebral hemorrhage, or cerebral infarction. It is advisable to maintain a light, easily digestible diet. Patients should seek timely medical attention when experiencing discomfort and receive standardized treatment under a doctor's supervision to promote recovery.
