What causes low blood pressure and difficulty sleeping?

Low blood pressure causing insomnia is usually due to excessive brain fatigue, insomnia disorder, cerebral hypoxia, and other reasons.

1. Overexertion

If someone has recently experienced high stress levels or excessive physical activity in daily life, they may develop low blood pressure and difficulty sleeping. This can also lead to symptoms such as body aches, fatigue, and slowed reaction time. These symptoms typically improve with adequate rest, and medication is not necessary.

2. Insomnia Disorder

Patients with insomnia often have an unstable nervous system, resulting in low blood pressure, rapid heart rate, and trouble falling asleep. They may also experience difficulty returning to sleep after waking up and frequent dreaming. Under a doctor's guidance, medications such as oxazepam tablets or zopiclone tablets can be taken to help relieve symptoms.

3. Cerebral Hypoxia

Low blood pressure can reduce cerebral perfusion, leading to cerebral ischemia and hypoxia, which in turn causes insomnia. Additional symptoms may include dizziness, memory decline, and slurred speech. Timely oxygen therapy under medical supervision can effectively alleviate sleep difficulties.

Besides the common causes listed above, other potential conditions such as hypoglycemia or heart disease may also contribute to insomnia. Because there are many possible causes, it is important to visit a hospital for examination and diagnosis, identify the underlying cause, and receive appropriate treatment accordingly.
