What causes feeling sleepy during the day but unable to sleep at night?

Feeling sleepy during the day and having difficulty falling asleep at night can be caused by various factors. Generally, it may be due to an unsatisfactory sleep environment or pathological factors such as neurasthenia and vegetative nerve disorders. To improve this situation, it is crucial to understand the underlying causes and take corresponding measures.

1. Poor Sleep Environment: Often, daytime sleepiness and nighttime insomnia can be caused by a poor sleep environment. For example, excessive noise in the surrounding environment or strong indoor lighting during sleep can adversely affect falling asleep. To improve this, it is recommended to try enhancing the sleep environment, such as maintaining indoor quietness and using blackout curtains or eye masks to dim the lights. These small changes may help improve sleep quality.

2. Neurasthenia: When a person is under constant stress and tension for a long time, they may experience symptoms of neurasthenia. This state can make people feel easily excited mentally and fatigued intellectually, often accompanied by irritability, moodiness, and sleep disorders. For the treatment of neurasthenia, medications such as Sertraline Hydrochloride Tablets or Fluvoxamine Maleate Tablets can be used under a doctor's guidance, which can help alleviate symptoms.

3. Vegetative Nerve Disorders: This condition is caused by a dysregulation of the vegetative nervous system, manifesting as chest tightness, palpitations, nausea, vomiting, insomnia, forgetfulness, and other symptoms. For vegetative nerve disorders, medications such as Oryzanol Tablets and Vitamin B1 Tablets can be taken under a doctor's advice. These drugs help nourish the nerves and relieve discomfort.

If more complex causes such as depression are suspected, it is recommended to seek medical attention for a detailed examination as soon as possible for a definitive diagnosis and targeted treatment. In daily life, developing good habits is also important, such as avoiding staying up late and maintaining a regular sleep schedule, which can help improve sleep issues. I hope these suggestions can help you achieve a healthy sleep state soon.
