If you have frequent neck pain or stiffness, you might feel relief when you crack your neck. But is cracking your neck bad for you?

Expert opinion on neck cracking is this: You’re fine if you crack gently and don’t overdo it. Like other types of joint cracking, it rarely leads to complications. However, there are some instances when neck cracking can cause problems.

Let’s look at why your neck cracks and the difference between harmless vs. harmful neck cracking.

Why Does My Neck Crack When I Move It?

The anatomy behind neck cracking is responsible for the characteristic popping noises.

Your neck contains seven small bones stacked on top of each other: the cervical vertebrae. Ligaments, tendons, and neck muscles provide support and stability to these bones.

The spinal cord begins at the base of the skull and runs through the middle of the vertebrae. Between the vertebrae are tough, rubbery discs that provide shock absorption when you move.

Your neck joints also contain synovial fluid. This fluid acts as a joint lubricant and contains gases like oxygen, carbon dioxide, and nitrogen.

You may hear popping, cracking, or grinding noises when you move your neck.

Escaping gases

When you crack a joint, the joint capsule that contains synovial fluid gets stretched. That movement releases gases from the joint, making a popping or snapping sound. The pressure change within the joint brings relief when you crack your neck.

Once the gas escapes from the joint capsule, you usually can’t crack the joint again right away. That’s because the gases take some time to build up again.

Joint popping, cracking, or snapping noises are familiar in knuckles, knees, and elbows, as well as in your neck.

Movement of connective tissues

Ligaments and tendons may also cause cracking noises when your joint moves, as the connective tissues move slightly out of place. Ligaments and tendons can make a snapping sound when they return to their original position.

Osteoarthritis

This type of arthritis is common. It happens when the smooth cartilage wears away from a joint’s surface. That can make the joint rough and cause grinding noises when it moves.

However, cracking your neck does not cause arthritis. Osteoarthritis occurs as people age and their joints wear out.

What Are the Benefits of Cracking Your Neck?

Cracking your neck can relieve pressure in your joints and make you feel better, especially after hours of sitting at a desk or looking at a laptop.

Neck cracking may also release feel-good hormones like oxytocin. Those can make you feel more relaxed and happier.

Sometimes, just hearing the pop of a cracked joint feels satisfying. A recent review looked at people under the care of a chiropractor. They associated hearing pops or cracks with a successful adjustment, whether the treatment worked or not.

Can Cracking Your Neck Cause Nerve Damage or Other Problems?

Scientific findings on neck cracking are scarce. That’s because, for the most part, it’s a harmless habit that makes most people feel better.

However, doctors warn that if you overdo it, there are some risks of habitual neck cracking.  Forcing your neck to crack repeatedly or too roughly can lead to problems. Potential dangers of cracking your neck too often include:

• Joint instability — The ligaments and tendons in your neck can become loose if you crack your neck too often. This can lead to hypermobility, when the neck isn’t supported properly and becomes too flexible. People with hypermobility issues are more prone to injury.
• Pinched nerve — Cracking your neck too often or forcefully could lead to a pinched nerve. A pinched nerve causes pain, tingling, and numbness. Symptoms can last from a few days to a few weeks.
• Vertebral artery dissection (VAD) — It’s rare, but cracking your neck hard could cause this serious, potentially life-threatening condition. It happens when a sudden movement causes a tear in an artery wall. That could decrease blood flow to the brain, putting you at risk for stroke.

How Can I Safely Crack My Neck?

Cracking your neck can help reduce neck pain and stiffness. It can relieve tension, especially after sitting in one place for a long time, like staring at a computer screen at work.

It’s important to use slow, gentle movements. Don’t jerk or pull your head or neck roughly.

To safely crack your neck:

• Sit upright in a chair and place one hand on your lower back.
• Place the other hand on top of your head.
• Gently pull your ear toward your shoulder. (Right ear to right shoulder; left ear to left shoulder.)
• Hold for 30 seconds and then repeat on the other side.

If you worry about cracking your neck too often, you can try gentle neck stretches instead. Ask your doctor or physical therapist for exercises to relieve neck pressure without cracking.

When Should I Call the Doctor About Neck Cracking?

If neck cracking or popping is constant, you should see your doctor. If it happens along with any of the following, you should call your doctor.

• A recent accident or injury — If you’ve been in a car accident or taken a fall, you may have other issues going on.
• Neck pain or swelling — These could indicate inflammation or infection.
• Recent spinal surgery — New sounds after spinal surgery may be normal, but it’s best to check with your doctor.

Should I have a chiropractic adjustment on my neck?

Many people find relief from spinal and neck issues through the help of a chiropractor. You may benefit from chiropractic care if you need to crack your neck several times a day.

Chiropractic care is often a complement to traditional medical care. In 2022, 11% of adults in the United States received chiropractic care, according to the National Center for Complementary and Integrative Health.

Licensed chiropractors manipulate the spine and other joints using their hands and special instruments. These adjustments can ease joint and muscle pain anywhere in the body.
