The clicking you hear in your head during a run most often traces back to your Eustachian tubes, the small channels connecting your middle ears to the back of your throat. Running alters pressure dynamics inside your head through a combination of repetitive impact, heavy breathing, and physiological shifts like fluid loss, and the Eustachian tubes are sensitive to all of it. Other causes exist, from involuntary muscle contractions in the soft palate to jaw joint mechanics, and the explanation that fits you depends on the rhythm, timing, and character of the sound.
How Your Eustachian Tubes React to Running
The Eustachian tubes normally stay closed and open briefly when you swallow or yawn to equalize pressure between your middle ear and the outside air. When these tubes stay more open than they should, a condition called patulous Eustachian tube, you can hear your own breathing amplified inside your head, your voice echoing oddly, and sometimes clicking or popping sounds. Vigorous exercise is a recognized trigger for this.{1World Journal of Otorhinolaryngology – Head and Neck Surgery. Patulous Eustachian tube (PET), a practical overview}
In a study of patients diagnosed with patulous Eustachian tube, roughly a quarter reported that exercise made their symptoms worse.2Otology & Neurotology. Patulous Eustachian Tube Dysfunction: Patient Demographics and Comorbidities The connection makes sense physiologically: during a hard run, you lose fluid through sweat, blood gets redirected to your working muscles, and the tissue surrounding the Eustachian tube opening in the back of the throat can temporarily shrink. That shrinkage holds the tube in a more open position than usual. Runners who have recently lost weight are especially prone, because the fat pad around the tube opening thins out with that weight loss.
Many people with this condition notice that symptoms are milder in the morning and worsen as the day goes on.1World Journal of Otorhinolaryngology – Head and Neck Surgery. Patulous Eustachian tube (PET), a practical overview That pattern has to do with overnight fluid pooling: while you sleep, tissue around the tube opening swells slightly from venous congestion, which actually helps keep the tube at its normal resting position. Once you’re upright, active, and sweating, gravity pulls fluid away and the tube gapes more easily. If you’ve noticed that the clicking only appears after you’ve been running for a while, or gets worse on a long run, this fluid-shift mechanism is a likely explanation.
Not everyone who hears clicking during a run has a diagnosable patulous tube. Milder, transient versions of the same process can happen when you’re dehydrated, running in dry air, or breathing hard through your mouth. Heavy mouth breathing during a run changes the pressure inside the nasopharynx with every breath cycle, and the Eustachian tube responds to those pressure swings with small opening-and-closing movements that register as clicks or pops.
Impact Forces and the Runner’s Skull
Running sends a shock wave through your skeleton with every footstrike. That vibration starts at the shins and travels upward through the legs, spine, and into the skull. Research measuring these forces found that stride frequency matters: runners taking fewer, longer strides experienced larger impact accelerations at the head compared to those using a higher cadence.3PLOS ONE. Head and Tibial Acceleration as a Function of Stride Frequency and Visual Feedback during Running The body dampens much of the shock before it reaches the skull, but some vibration always gets through, and at lower cadences the magnitude goes up substantially.
These vibrations probably don’t cause clicking on their own for most people, but they can amplify clicking that’s already happening from another source. If your Eustachian tube is borderline open, the repeated jolts from each footstrike could nudge it into producing an audible click in sync with every step. Similarly, if there’s a small amount of fluid in the middle ear, impact forces can slosh it around just enough to hear. Some runners describe the clicking as locked perfectly to their stride, which points toward the mechanical impact as either the direct cause or a contributing factor.
Switching to a softer running surface, bumping up your cadence, or wearing well-cushioned shoes can all reduce the peak head acceleration from each stride.3PLOS ONE. Head and Tibial Acceleration as a Function of Stride Frequency and Visual Feedback during Running If the clicking tracks reliably with your footstrike, experimenting with these variables is a reasonable first test before seeing a doctor.
Palatal Myoclonus and Rhythmic Clicking
A completely different kind of clicking comes from involuntary contractions of the muscles in the soft palate. This condition, called palatal myoclonus, produces rhythmic, rapid jerking movements that can open and close the Eustachian tube in a repetitive pattern, creating a clicking sound the person hears inside their head.4PubMed Central. Palatal myoclonus associated with orofacial buccal dystonia The rhythm is typically regular and fast, often one to several clicks per second, and it can persist even at rest. Exercise and physical stress can bring it on or make it louder.
The mechanism involves pressure changes generated by the muscle contractions themselves. Each time the palatal muscles fire, they tug on tissue near the Eustachian tube opening, creating small fluctuations in middle ear pressure that vibrate the eardrum just enough to register as a click.5Journal of Movement Disorders. Focal Unilateral Palatal Myoclonus Causing Objective Clicking Tinnitus without Uvula Elevation Diagnosed by Concurrent Auscultation This is fundamentally different from the pressure-equalization clicking of the Eustachian tube on its own: the sound is being driven by a misfiring motor signal rather than by passive changes in airway pressure.
Palatal myoclonus is considered rare, but it has been documented across a wide age range. One published case involved a nine-year-old boy with distressing clicking tinnitus from palatal myoclonus that was successfully treated with botulinum toxin injections into the palatal muscles.6PubMed. Essential Palatal Myoclonus and Clicking Tinnitus in a Nine-Year-Old Boy-A Case Report Other treatment options include certain muscle-relaxing medications. The point is that persistent rhythmic clicking doesn’t have to be something you just live with.
How do you tell palatal myoclonus apart from Eustachian tube clicking? The biggest clue is rhythm. Eustachian tube clicking from running tends to be irregular, loosely syncing with breathing or footstrikes and fading when you stop running. Palatal myoclonus clicking is metronomic: it beats at a steady rate regardless of what you’re doing. If you can feel a fluttering sensation in the back of your throat or the roof of your mouth at the same time you hear the clicking, that’s another strong indicator pointing toward the palate.
Sounds Only You Can Hear vs. Sounds Others Can Detect
Most head clicking during running falls into the category of subjective tinnitus, meaning only you can hear it.7JAMA Otolaryngology–Head & Neck Surgery. Objective Audible Clicking in Ear: Presentation This is actually reassuring, because it suggests the sound is generated by minor internal pressure fluctuations or muscle activity rather than by a structural abnormality producing vibrations loud enough for the outside world to pick up.
In rare instances, clicking in the head is loud enough that someone standing nearby, or a doctor using a stethoscope near the ear, can hear it. This is called objective tinnitus.7JAMA Otolaryngology–Head & Neck Surgery. Objective Audible Clicking in Ear: Presentation Objective clicking narrows the diagnostic possibilities because it means there is a detectable physical source producing the vibration. Palatal myoclonus is one of the conditions that can produce audible-to-others clicking. Vascular causes, where blood flow near the ear creates a sound, are another category, though those tend to produce a pulsing or whooshing noise rather than a clean click.
If a running partner can actually hear the clicking coming from your head or ear, mention that to a doctor. It doesn’t necessarily signal something dangerous, but it provides a concrete diagnostic starting point that imaging or a physical exam can pursue.
Other Mechanical Sources of Clicking
The head is full of joints, muscles, and fluid-filled spaces, and several of them can produce clicking during repetitive motion.
The temporomandibular joint (TMJ) sits just in front of each ear and connects your jawbone to your skull. Many people have mild clicking in this joint even at rest, but the repetitive jarring of running can make it louder or more noticeable. If you tend to clench your jaw when you run, or breathe with your mouth hanging open in a way that shifts your jaw position, the disc inside the joint can slip slightly with each stride and click. TMJ-related clicking tends to feel localized right at the jaw rather than deep inside the ear, and you can usually reproduce it by deliberately opening and closing your mouth.
The muscles of the middle ear can also generate sounds. The tensor tympani and the stapedius are tiny muscles that normally contract reflexively to protect your inner ear from loud noises. Under stress, fatigue, or heightened nervous-system activity, these muscles can misfire and spasm. Tensor tympani syndrome, as it is sometimes called, often produces a low-pitched thumping or rumbling rather than a sharp click, and it frequently comes with a sensation of fullness or pressure in the ear. A hard run combines physical fatigue, elevated adrenaline, and heavy breathing, all of which can trigger these spasms in susceptible people.
The cervical spine is yet another potential contributor. The joints between vertebrae in your neck can produce clicking or crunching sounds during repetitive movement. Most runners don’t notice it because ambient noise and music mask it, but in a quiet environment you might pick up on faint clicking from your neck that you assumed was coming from inside your ear. Neck-origin clicking often changes character or disappears when you tilt your head in different directions, which can help you distinguish it from an ear-related source.
When Clicking Deserves Medical Attention
Occasional clicking during a run that fades once you cool down is, for most people, nothing more than a quirk of their anatomy and physiology. But certain patterns are worth investigating.
Clicking that is truly rhythmic and constant, persisting even when you’re sitting still after your run, could point to palatal myoclonus or another neurological source. Clicking accompanied by hearing loss, vertigo, or ear pain warrants an evaluation because those symptoms suggest something beyond a transient pressure issue. And if the clicking started suddenly after a head impact or very loud noise exposure, the structures of the inner ear themselves may need examination.
Runners who notice clicking only after significant weight loss should mention it to their doctor, since patulous Eustachian tube is closely associated with tissue changes around the tube opening. Among patients with the condition, about two thirds reported that their symptoms increased in frequency and duration over time.2Otology & Neurotology. Patulous Eustachian Tube Dysfunction: Patient Demographics and Comorbidities Early recognition can make management easier and prevent the annoyance from escalating.
Strategies That Can Quiet the Click
If the Eustachian tube is your suspected culprit, staying well hydrated during runs is the simplest intervention. Fluid loss shrinks the mucosal tissue around the tube opening, making it easier for the tube to stay ajar. Sipping water before and during longer runs, especially in hot or dry conditions, can reduce the effect. Some runners also find that using a saline nasal spray before heading out helps keep the nasal and nasopharyngeal tissue hydrated enough to function normally.
Nasal breathing, when the pace allows it, stabilizes pressure in the nasopharynx better than mouth breathing does. Runners who alternate between nose and mouth breathing throughout a run sometimes notice that the clicking only appears during the mouth-breathing stretches. Training yourself to return to nasal breathing during easier portions of a run can serve as both a test and a partial fix.
For impact-related clicking, increasing your stride rate so you take shorter, quicker steps rather than long, bounding strides reduces the peak force your head absorbs with each footstrike.3PLOS ONE. Head and Tibial Acceleration as a Function of Stride Frequency and Visual Feedback during Running Running on trails, grass, or a track instead of concrete also helps dampen the vibration that reaches your skull. If you’re already a high-cadence runner on soft surfaces and still hear stride-locked clicking, the impact force is probably a contributing factor rather than the main cause.
For palatal myoclonus, home interventions aimed at pressure and hydration won’t help much because the problem is involuntary muscle activity, not passive tube dynamics. Treatments in this case range from medications that calm muscle contractions to targeted botulinum toxin injections for persistent cases.6PubMed. Essential Palatal Myoclonus and Clicking Tinnitus in a Nine-Year-Old Boy-A Case Report A neurologist or ENT specialist can distinguish palatal myoclonus from other causes with a quick examination of the soft palate, sometimes just by watching for visible rhythmic movements while you sit in the exam chair.
Jaw clenching during runs contributes to TMJ-related clicking for many runners. Consciously relaxing the jaw, keeping the lips lightly closed with the teeth slightly apart, and periodically dropping the shoulders can reduce the tension that accumulates over the course of a run. Some people find it helpful to lightly rest the tip of the tongue on the roof of the mouth just behind the front teeth, a trick borrowed from physical therapy that naturally positions the jaw in a relaxed state. A mouthguard designed for sport may help runners who clench despite their best conscious efforts, though it takes some getting used to during heavy breathing.
