What are the causes of insomnia?

Insomnia can be caused by various factors, including environmental stimuli, poor lifestyle habits, depression, neurasthenia, hyperthyroidism, and others. 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. Environmental Stimuli

Unfavorable sleeping environments such as noise, excessive light, or high temperature may affect sleep quality and lead to insomnia. It is advisable to ensure a quiet and comfortable sleep environment with suitable temperature and lighting. Using auxiliary tools like earplugs or eye masks may help improve sleep conditions.

2. Poor Lifestyle Habits

Consuming beverages such as coffee or tea before bedtime can easily stimulate the central nervous system, leading to difficulty falling asleep and reduced sleep quality. Establishing a regular sleep schedule, avoiding such drinks before bed, and practicing relaxation techniques like deep breathing or yoga can help improve sleep quality.

3. Depression

Depression may be associated with factors such as relationship breakups or academic failure. Patients may experience persistent low mood, which can overstimulate the brain's nerves and result in insomnia and other sleep disturbances, often accompanied by feelings of sadness. It is recommended that patients take medications such as maprotiline hydrochloride tablets, clomipramine hydrochloride tablets, or amitriptyline hydrochloride tablets as prescribed by their doctor.

4. Neurasthenia

This condition may be related to excessive mental stress or overuse of the brain. It can lead to dysfunction of the cerebral cortex, resulting in symptoms such as difficulty falling asleep, frequent awakenings, insomnia, and possibly vivid dreams. Patients are advised to take medications such as vitamin B12 tablets, oryzanol tablets, or Zhenyuan tablets according to medical instructions.

5. Hyperthyroidism

This condition is usually caused by negative emotions or excessive thyroid hormone production. It can disrupt hormonal balance in the body, impair sleep quality, cause insomnia, and may also be accompanied by palpitations. Patients should take medications such as propylthiouracil tablets, carbimazole tablets, or metoprolol tartrate tablets under a doctor’s supervision to manage symptoms.

In daily life, patients are advised to maintain a light diet, drink plenty of warm water, stay calm and emotionally balanced, and consider drinking a cup of warm milk before bedtime, which may help alleviate discomfort and improve sleep.
