What causes numbness in fingers at night, and what should be done about it?

Numbness in the fingers at night may be caused by physiological factors, or by pathological conditions such as peripheral neuritis or cervical spondylosis. Treatment can be achieved through general management or medication. Specific details are as follows:

I. Physiological Factors

If a patient sleeps in an incorrect position at night, pressure on one arm or hand may lead to localized nerve compression, resulting in finger numbness during sleep. Usually, no special treatment is required; adjusting sleeping posture can improve the condition.

II. Pathological Factors

1. Peripheral Neuritis

This is usually caused by various factors affecting the peripheral nerves, such as nutritional or metabolic disturbances. It mainly manifests as sudden chills and numbness in the limbs. Under a doctor's guidance, medications such as Oryzanol tablets or Mecobalamin tablets may be taken for treatment.

2. Cervical Spondylosis

Due to herniated cervical discs or local irritation affecting nerve roots, symptoms may worsen during nighttime sleep—especially due to unsuitable pillows or improper head positioning—leading to numbness in the upper limbs. Under medical supervision, medications such as Diclofenac Sodium Sustained-Release Tablets or Jingfukang Granules may be used for treatment.

In addition to the above causes, finger numbness at night could also result from insufficient cerebral blood supply, cerebral hemorrhage, or cerebral infarction. It is important to get adequate rest and avoid excessive fatigue. Patients are advised to seek timely medical attention when experiencing discomfort and to receive standardized treatment under professional guidance, which helps promote recovery.
