What Causes Carpal Tunnel Syndrome?
Carpal Tunnel Syndrome happens when the median nerve, which runs through a narrow channel in your wrist, becomes compressed. This nerve helps control feeling and movement in the thumb, index finger, middle finger, and part of the ring finger. When the space in the wrist narrows or swells, pressure on the nerve can lead to pain, numbness, or weakness in the hand.
A few common causes and risk factors include:
- Repetitive hand movements: Tasks that involve frequent motion, like typing or assembly work, can put stress on the wrist.
- Injuries: A sprain or fracture can change the shape of the carpal tunnel, squeezing the nerve.
- Inflammatory conditions: Health issues like rheumatoid arthritis can cause swelling in the wrist.
- Lifestyle factors: Smoking, obesity, high salt intake, and limited physical activity may increase your risk.
Tips for Preventing CTS
While not every case is preventable, there are simple changes that can lower your risk:
- Loosen your grip: Avoid holding objects too tightly or pounding the keyboard with too much force.
- Take regular breaks: Stretch and relax your hands and wrists throughout the day.
- Adjust your workstation: Make sure your keyboard and mouse are positioned to keep your wrists in a neutral, comfortable position.
- Keep your hands warm: If your work environment is chilly, consider wearing gloves to help avoid stiffness.
- Choose ergonomic tools: A supportive mouse or keyboard can go a long way in preventing discomfort.
- Manage chronic conditions: Controlling health issues like diabetes or arthritis can reduce your chances of developing CTS.
