Why Do My Hands Go Numb at Night? Common Causes and When to See a Hand Specialist
Waking up with numb, tingling or “pins and needles” in your hands can be unsettling. While occasional numbness is often harmless, persistent symptoms may indicate an underlying condition affecting the nerves, tendons or joints in your hand, wrist or arm.
At Manchester Hand Surgeons, one of the most common questions we hear from patients is: “Why do my hands keep going numb at night?” Understanding the possible causes can help you recognise when it’s time to seek expert advice.
Why Does Hand Numbness Often Happen at Night?
Many people notice numbness more during sleep because of the positions they naturally adopt overnight. Sleeping with bent wrists, elbows tucked under the body, or arms positioned above the head can temporarily compress nerves and reduce blood flow.
If symptoms resolve quickly and occur only occasionally, there may be little cause for concern. However, regular nighttime numbness could indicate a condition that requires assessment and treatment.
Carpal Tunnel Syndrome
One of the most common causes of nighttime hand numbness is Carpal Tunnel Syndrome (CTS).
The carpal tunnel is a narrow passageway in the wrist through which the median nerve travels. When pressure builds within this space, the nerve becomes compressed, leading to symptoms such as:
- Tingling in the thumb, index and middle fingers
- Numbness during the night
- Pain that wakes you from sleep
- Weakness when gripping objects
- Difficulty with fine motor tasks
Many patients find themselves shaking their hands in the middle of the night to relieve symptoms.
Who Is Most at Risk?
Carpal tunnel syndrome is more common in people who:
- Use keyboards or tools regularly
- Perform repetitive hand movements
- Are pregnant
- Have diabetes
- Are experiencing menopause or perimenopause
- Have inflammatory conditions such as rheumatoid arthritis
Cubital Tunnel Syndrome
Not all hand numbness originates from the wrist.
Cubital Tunnel Syndrome occurs when the ulnar nerve becomes compressed at the elbow. This nerve supplies sensation to the little finger and part of the ring finger.
Symptoms often include:
- Numbness in the little finger and ring finger
- Symptoms that worsen when the elbow is bent
- Weakness in hand grip
- Clumsiness when using the fingers
People who sleep with their elbows tightly bent may notice symptoms, particularly during the night.
Arthritis and Joint Problems
Arthritis does not directly cause nerve compression, but swelling around joints can place pressure on nearby nerves.
Patients with hand or wrist arthritis may experience:
- Joint stiffness
- Swelling
- Pain during movement
- Reduced grip strength
- Episodes of tingling or numbness
Arthritic symptoms are often worse first thing in the morning and can contribute to disturbed sleep.
Trigger Finger and Tendon Conditions
Inflamed tendons within the hand can occasionally contribute to discomfort and altered sensation. Although trigger finger typically causes locking or catching of a finger rather than numbness, some patients describe associated tingling or discomfort that is more noticeable at night.
Could Menopause Be a Factor?
Hormonal changes during perimenopause and menopause can increase the risk of developing nerve compression conditions, particularly carpal tunnel syndrome.
Fluctuating hormone levels can contribute to fluid retention and tissue swelling around the wrist, increasing pressure on the median nerve. Women may therefore experience:
- Nighttime hand numbness
- Tingling sensations
- Wrist discomfort
- Reduced grip strength
If symptoms appear during menopause, it is important not to dismiss them as simply part of the ageing process.
When Should You See a Hand Specialist?
Occasional numbness may not require treatment. However, you should seek specialist advice if:
- Symptoms occur regularly
- Numbness wakes you at night
- Symptoms are becoming more frequent
- You experience weakness in your hand
- You are dropping objects unexpectedly
- Symptoms affect your work or daily activities
- Numbness persists during the day
Early diagnosis often leads to simpler and more effective treatment options.
Treatment Options
Treatment depends on the underlying cause and severity of symptoms.
Possible treatments include:
Non-Surgical Treatments
- Wrist splints worn at night
- Activity modification
- Anti-inflammatory medication
- Steroid injections
- Hand therapy exercises
Surgical Treatment
For patients with more advanced nerve compression or symptoms that have not improved with conservative treatment, surgery may be recommended.
Procedures such as carpal tunnel release surgery are commonly performed to relieve pressure on the affected nerve and help restore normal sensation and function.
Don’t Ignore Persistent Hand Numbness
Although hand numbness at night is common, persistent symptoms should not be ignored. Conditions such as carpal tunnel syndrome and cubital tunnel syndrome can worsen over time and may lead to permanent nerve damage if left untreated.
If you are regularly waking with numb, tingling or painful hands, an assessment by an experienced hand surgeon can help identify the cause and determine the most appropriate treatment.
