What are the reasons for insomnia and inability to sleep?

Insomnia or difficulty falling asleep may be caused by poor lifestyle habits, environmental stimuli, depression, sleep apnea syndrome, hypertension, and other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Poor Lifestyle Habits

For example, watching stimulating movies or using electronic devices before bedtime may interfere with the sleep cycle, leading to insomnia. It is advisable to avoid stimulating activities before sleep and reduce screen time. Drinking a cup of warm milk may help improve sleep quality.

2. Environmental Stimuli

Excessive noise in the sleeping environment or an overly firm mattress may prevent the brain's nerves from relaxing, thereby causing insomnia. It is recommended to ensure a quiet sleeping environment and use a soft, comfortable mattress and pillow to improve sleep quality.

3. Depression

This may be related to factors such as academic failure or introverted personality. After onset, patients may experience symptoms like low mood and depression. These abnormal emotional states can overactivate the brain, making it difficult to enter deep sleep, and may also be accompanied by feelings of anxiety. Patients are advised to take medications such as maprotiline hydrochloride tablets, clomipramine hydrochloride tablets, or amitriptyline hydrochloride tablets as prescribed by a doctor.

4. Sleep Apnea Syndrome

This may be associated with factors such as enlarged tonsils or anatomical abnormalities in the upper respiratory tract. Patients may experience breathing difficulties during sleep, resulting in insomnia and possibly snoring. It is recommended that patients take medications such as alprazolam tablets, aminophylline tablets, or acetazolamide tablets as directed by their physician.

5. Hypertension

This is generally caused by factors such as medication side effects or underlying diabetes. Poor blood pressure control may lead to increased intracranial pressure and nervous exhaustion, resulting in insomnia, possibly accompanied by fatigue. Patients should take medications such as methyldopa tablets, captopril sustained-release tablets, or irbesartan dispersible tablets under medical supervision to alleviate symptoms.

In daily life, patients are advised to maintain a light diet, drink plenty of warm water, ensure adequate sleep, avoid staying up late, follow a low-salt diet, and consume appropriate amounts of fresh vegetables and fruits such as radishes, lettuce, and apples, which may help relieve discomfort.
