The sternocleidomastoid (SCM) muscle is one of the most important muscles in the neck, responsible for turning the head, flexing the neck, and elevating the sternum during breathing. However, due to poor posture, stress, injury, or overuse, the SCM muscle can become tight and tense, leading to neck pain, headaches, and other discomforts. In this article, we’ll explore the causes and symptoms of SCM tension, and offer practical tips and techniques to relax and release this crucial muscle.

Understanding the Sternocleidomastoid Muscle
Before we dive into the techniques to relax the SCM muscle, let’s take a closer look at this muscle’s anatomy and function. The SCM muscle is a long, strap-like muscle that runs from the base of the skull, behind the ear, and down to the collarbone and sternum. It is divided into two parts: the sternal head and the clavicular head, which work together to flex and rotate the neck.
The SCM muscle is innervated by the spinal accessory nerve (cranial nerve XI), which controls the movement of the neck and shoulders. When the SCM muscle is tight or overactive, it can compress the nerves and blood vessels in the neck, leading to pain, tingling, and other symptoms.
Causes and Symptoms of SCM Tension
SCM tension can be caused by a variety of factors, including:
- Poor posture: Sitting or standing for long periods in a slouched or hunched position can strain the neck and shoulders, causing the SCM muscle to tighten.
- Stress and tension: Emotional stress, anxiety, and tension can cause the muscles in the neck and shoulders to contract, leading to SCM tension.
- Injury or trauma: Whiplash, falls, and other types of trauma can damage the SCM muscle, causing it to become tight and painful.
- Overuse: Repetitive movements of the neck and shoulders, such as typing, texting, or playing musical instruments, can strain the SCM muscle and lead to tension and pain.
The symptoms of SCM tension may include:
- Neck pain, stiffness, or soreness
- Headaches, especially in the temples or behind the eyes
- Tenderness or sensitivity in the neck and shoulder area
- Reduced range of motion in the neck
- Dizziness or vertigo
- Jaw pain or stiffness
- Tinnitus (ringing in the ears)
- Eye pain, blurred vision, or sensitivity to light
If you experience any of these symptoms, it’s essential to consult a healthcare professional to rule out any underlying conditions and receive appropriate treatment.
Techniques to Relax the Sternocleidomastoid Muscle
There are several effective techniques to relax and release the tension in the SCM muscle, including:
Stretching is an excellent way to alleviate SCM tension and improve neck mobility. Here’s a simple stretch you can do at home:
- Sit or stand up straight, with your shoulders relaxed.
- Tilt your head to one side, bringing your ear towards your shoulder.
- Use your hand to gently pull your head further into the stretch, feeling the stretch in your neck and shoulder.
- Hold the stretch for 20-30 seconds, then repeat on the other side.
Massage is another effective way to release tension in the SCM muscle and promote relaxation. You can use your fingers or a massage ball to apply pressure to the muscle, starting from the base of the skull and working your way down to the collarbone. Apply firm but gentle pressure, and focus on any areas of tenderness or tightness.
- Heat Therapy
Applying heat to the neck and shoulder area can help relax the SCM muscle and reduce pain and stiffness. You can use a hot towel, heating pad, or warm compress to apply heat to the affected area for 15-20 minutes at a time.
- Cold Therapy
Cold therapy can also be helpful in reducing inflammation and easing pain in the neck and shoulder area. You can use an ice pack or frozen gel pack wrapped in a towel to apply cold to the affected area for 10-15 minutes at a time.
- Posture Correction
Correcting your posture can help alleviate SCM tension and prevent it from recurring. Make sure to sit or stand up straight, with your shoulders relaxed and your chin slightly tucked in. Avoid slouching or hunching forward, as this can strain the neck and shoulder muscles.
- Mind-Body Techniques
Mind-body techniques, such as yoga, tai chi, or meditation, can be helpful in reducing stress and tension in the neck and shoulders. These practices promote relaxation and mindfulness, which can help alleviate SCM tension and improve overall well-being.
- Physical Therapy
If your SCM tension is severe or chronic, you may benefit from physical therapy. A physical therapist can assess your posture, range of motion, and muscle strength, and develop a personalized treatment plan to help alleviate your symptoms and improve your neck and shoulder function.
The sternocleidomastoid muscle is a crucial muscle in the neck, responsible for neck movement and breathing. However, due to poor posture, stress, injury, or overuse, the SCM muscle can become tight and tense, leading to pain and discomfort. Fortunately, there are several effective techniques to relax and release SCM tension, including stretching, massage, heat and cold therapy, posture correction, mind-body techniques, and physical therapy. By incorporating these techniques into your daily routine, you can alleviate SCM tension, improve your neck and shoulder function, and promote overall well-being.
