What should I do if my mind is too active at night and I can't fall asleep?

There are many reasons for overactive thinking at night that leads to difficulty falling asleep. Most cases are caused by mental disorders, endocrine imbalances, or physiological excitement. This condition can be treated with oral medications. Specific approaches are as follows.

I. Non-disease Factors

Overactive thinking at night may result from physiological excitement. In such cases, it may help to get out of bed and sit quietly in a calm place, practicing mindful breathing. The key to mindful breathing is focusing attention entirely on your breath—concentrating your mind on the slow, deep rhythm of inhalation and exhalation. By doing so, the brain gradually forgets other sources of mental stimulation, restores calmness, and becomes more conducive to sleep.

II. Disease-related Factors

1. Endocrine Disorders

The endocrine system produces various hormones—such as luteinizing hormone, thyroid hormones, and sex hormones—that regulate the body's internal balance. Endocrine imbalances can lead to sleep disturbances. It is recommended to eat more vegetables and fruits, reduce intake of greasy and stimulating foods, use plant-based oils for cooking, drink plenty of water, and ensure smooth excretion through urine, bowel movements, and sweat. Additionally, maintain moderate exercise, regular作息 (daily routines), sufficient sleep, avoid staying up late, and prevent disruptions to the day-night cycle.

2. Mental Disorders

Insomnia caused by mental disorders is relatively common. Sleep can often be restored quickly using sedative-hypnotic medications, administered orally or via intramuscular injection. Commonly used drugs include lorazepam, oxazepam, and alprazolam.
