Why do I always feel sleepy when sitting?

Sleepiness while sitting may result from non-medical factors such as insufficient sleep, or could be caused by medical conditions like neurasthenia or depression. If symptoms are significant, timely medical evaluation is recommended. Under a doctor's guidance, treatment options including medications or psychological therapies should be considered.

1. Insufficient sleep: Prolonged work hours or excessive excitement before bedtime may lead to inadequate sleep, resulting in daytime drowsiness, fatigue, dizziness, or headaches the following day. These symptoms typically resolve on their own after sufficient rest and sleep recovery.

2. Neurasthenia: Chronic stress from life or work can lead to neurasthenia, a condition commonly presenting with clinical symptoms such as insomnia, vivid dreams, and anxiety. Long-term neurasthenia often causes sleep deprivation, so persistent drowsiness while sitting may indicate this condition. Treatment should be guided by a physician and may include medications such as Zaoren Anshen Capsules or Procaine Hydrochloride Tablets. Patients may also benefit from psychological therapies such as Morita therapy or cognitive behavioral therapy under the supervision of a mental health professional.

3. Depression: Depression triggered by major life events or other brain-related disorders commonly manifests as excessive sleepiness, emotional apathy, and fatigue. Therefore, the aforementioned symptoms could also indicate depression. Treatment requires physician-prescribed medications such as Mianserin Hydrochloride Tablets or Venlafaxine Hydrochloride Capsules. Additionally, psychotherapies such as hypnotherapy or cognitive behavioral therapy, conducted under the guidance of a mental health professional, can support recovery.
