 How to keep your nerves healthy in your arms and hands

Your nerves play a big role in helping you move, feel, and grip things. When they get pinched or damaged, it can lead to pain, numbness, or weakness. In this post, we’ll break down common nerve problems in your arms, wrists, and hands, plus simple ways to keep them healthy.

Why your nerves matter

Think of nerves as tiny highways sending signals between your brain, spinal cord, and muscles. They help you pick up a cup, type on a keyboard, and even feel temperature changes. If these highways get blocked or squeezed, your hands might tingle, go numb, or feel weak.

Common nerve problems in the upper extremity

1. Carpal tunnel syndrome (Wrist nerve pinch)

What causes it? Too much pressure on the median nerve in your wrist. Often from typing, gripping tools, or using your phone a lot.

Signs:

  • Tingling or numbness in your thumb, index, and middle fingers
  • Weak grip
  • Pain, especially at night

How to prevent it:

  • Keep your wrists in a neutral position when using a keyboard or phone.
  • Stretch your hands and wrists regularly.
  • Wear a wrist brace at night if needed.

2. Ulnar nerve entrapment (Funny bone nerve issue)

What causes it? Too much bending of the elbow, leaning on hard surfaces, or repetitive arm motions.

Signs:

  • Tingling or numbness in your ring and pinky fingers
  • Weak grip
  • Pain along the inside of your elbow

How to prevent it:

  • Avoid resting your elbows on hard surfaces for long periods.
  • Do gentle stretches and exercises for your arm and hand.
  • Wear an elbow brace if symptoms show up at night.

3. Radial nerve palsy (Wrist drop)

4. Thoracic outlet syndrome (Pinched shoulder nerve)

What causes it? Poor posture, carrying heavy bags, or repetitive overhead movements can squeeze the nerves in your shoulder area.

Signs:

  • Tingling, pain, or numbness in your arm or hand
  • Weakness in your grip
  • Swelling or color changes in your hand (in severe cases)

How to prevent it:

  • Sit up straight, especially when using a computer or phone.
  • Stretch and strengthen your shoulders.
  • Avoid carrying heavy bags on one shoulder all the time.

Easy ways to keep your nerves healthy

  1. Fix your posture: Keep your shoulders relaxed and your wrists in a neutral position when working.
  2. Stretch often: Move your arms, wrists, and fingers to keep them flexible.
  3. Strengthen Your Muscles: Building strong muscles around your nerves helps reduce strain.
  4. Take breaks: If you do a lot of repetitive work, rest your hands and arms often.
  5. Stay hydrated & eat well: Good nutrition helps your nerves function properly.
  6. Listen to your body: If you feel numbness, tingling, or weakness, don’t ignore it—take action early.

Exercises to support nerve health

Building on our previous post about strengthening the upper body, here are some simple exercises to keep your nerves and muscles in top shape:

  1. Wrist Circles: Rotate your wrists in small circles to improve mobility and blood flow.

  2. Nerve Glides: Slowly stretch your fingers, wrist, and arm in different directions to help the nerves move smoothly.

  3. Shoulder Rolls: Roll your shoulders backward and forward to relieve tension and improve posture.

  4. Finger Taps: Tap each finger to your thumb one at a time to improve coordination and nerve function.

  5. Neck Stretches: Gently tilt your head side to side and forward to release tension on nerves running through your neck and shoulders.

These exercises will not only keep your muscles strong but also support better nerve function, reducing the risk of pinched or compressed nerves.

Taking care of your nerves helps you stay pain-free and keep your hands and arms working well. Make small changes today, and your nerves will thank you!

When to see a doctor

If your symptoms don’t improve, get worse, or make it hard to do daily tasks, see a doctor. The sooner nerve issues are treated, the better the outcome.
