Introduction: When Dizziness Isn’t Just a Diet or Inner Ear Issue
Persistent dizziness can be perplexing, often attributed to nutrition, dehydration, or inner-ear trouble. Yet some cases may hinge on a single neck muscle: the sternocleidomastoid (SCM). A growing number of clinicians and health influencers have highlighted the SCM as a potential culprit behind balance problems. By understanding how this muscle works and how to address it, you may find relief from dizzy spells that otherwise linger.
What the Balance System Really Does
Experts describe balance as a coordination of three sensory inputs: vision, the inner ear, and body proprioception. Your eyes help you interpret what you see, the inner ear detects head movement through minute crystals, and body receptors sense stretch and position. When one piece sends confusing signals—such as through an imbalanced or spasmed SCM—the brain may misread head position, resulting in dizziness or unsteadiness.
The SCM Muscle: A Key Player in Head Position
The SCM runs from the sternum and collarbone up to the back of the skull. It’s essential for moving your head up, down, side-to-side, and turning it. Because the SCM is so involved in orienting your head in space, any imbalance between the two sides or a transient spasm can disrupt the brain’s integration of balance signals. In some cases, persistent tension in this muscle can create a chronic sense of dizziness that won’t respond to ordinary rest or hydration.
Two-Part Strategy: Release and Strengthen the SCM
Health professionals like Dr. Joe Damiani have shared practical techniques designed to both release tension in the SCM and strengthen it to restore proper balance signaling. The approach is two-fold: release the muscle to reduce abnormal signals, and then activate and strengthen it to maintain stable head position over time.
Part 1: Releasing the SCM
Step-by-step guidance focuses on applying light, controlled pressure to relax the muscle around the jaw and collarbone. A common method involves starting with a hand placed on the side of the head and gently turning toward the side to encourage a soft release at the muscle, then tracing along to the collarbone and up toward the area behind the ear. The goal is gradual, steady pressure rather than any quick, forceful motion. An alternate technique uses two fingers placed just below the ear to trace downward toward the collarbone while turning, which can help relax the muscle fibers. It’s important to proceed slowly and avoid pain; the aim is comfortable tension release rather than a deep tissue workout.
Part 2: Activating and Strengthening the SCM
After release, the next phase focuses on controlled activation to normalize messages sent to the balance system. A commonly recommended sequence includes: starting with a chin tuck to set alignment, then placing one hand on the head and rotating toward that hand to engage the SCM, switching hands and repeating the rotation. This is typically performed five times on each side. A second variation substitutes rotation with a gentle tilt: place a hand on the side of the head, tilt the head down toward that hand, then lift back up and repeat five times. The key is slow, deliberate movements, ensuring the neck remains supported and pain-free. By alternating release and strengthening of both SCMs, balance signals can become more consistent, potentially reducing dizziness and neck tension over time.
What to Know Before You Try This at Home
While these techniques are accessible, they may not be suitable for everyone. People with recent neck injuries, osteoporosis, or certain spine conditions should consult a healthcare professional before attempting new neck exercises. If dizziness is severe, persistent, or accompanied by other symptoms such as severe headache, vision changes, or numbness, seek urgent medical evaluation. A comprehensive assessment can determine whether SCM tension is the primary driver or if other balance disorders are at play. When implemented with care, release and strengthening routines can become part of a broader plan including posture training, physical therapy, and lifestyle adjustments to support long-term balance health.
Bottom Line: A Balanced Approach for Better Stability
In some dizziness cases, the SCM muscle’s role in head positioning may be a surprising but meaningful factor. By combining gentle release techniques with targeted strengthening, you may normalize the brain’s interpretation of balance signals and experience less dizziness. Remember to approach these exercises gradually, prioritize safety, and consult a clinician if you’re unsure about your symptoms or how to begin.
