I can't fall asleep at night unless I move around; otherwise, my whole body feels uncomfortable.

Being unable to fall asleep and feeling uncomfortable all over the body at night unless moving occasionally may be caused by calcium deficiency, neurasthenia, restless legs syndrome, or other conditions. Medication can be used to improve these symptoms. Specific causes are analyzed as follows:

1. Calcium Deficiency

If the body lacks calcium, it may lead to decreased blood calcium ion concentration and hypocalcemia, resulting in shallow sleep and frequent awakenings at night—symptoms consistent with the above description. Under a doctor's guidance, medications such as calcium gluconate and zinc oral solution or tricalcium chewable tablets may be used for treatment.

2. Neurasthenia

Prolonged mental stress or excessive pressure may cause overexcitability of the nervous system, thereby disrupting nighttime sleep and causing discomfort when remaining still during sleep. Under medical supervision, medications such as fluoxetine hydrochloride capsules or venlafaxine hydrochloride sustained-release tablets may be prescribed.

3. Restless Legs Syndrome

Restless legs syndrome is usually caused by genetic factors, anemia, or other reasons. Symptoms may include crawling sensations in the lower limbs or swelling; some patients may also experience discomfort unless they move their legs. With medical assistance, drugs such as levodopa tablets or ropinirole hydrochloride tablets may be used for treatment.

In addition, similar symptoms could also result from anxiety disorder, depression, heart failure, or other conditions. It is recommended that patients seek timely medical evaluation at a hospital, obtain an accurate diagnosis, and actively pursue appropriate treatment accordingly.
