EDITOR’S SUMMARY: Balance begins long before a baby takes a first step—and when it falters, the effects ripple through movement, focus, and learning. From the hidden architecture of the inner ear to the fading art of free play, this exploration reveals how the body’s sense of orientation links movement and mind. Insights from developmental optometry and movement science highlight how simple acts—spinning, climbing, crawling, even playful dizziness—strengthen coordination and restore confidence in old age.
You might not give much thought to balance—until it starts to slip. Maybe your child can’t sit still to read, or you’ve noticed your own coordination isn’t what it used to be. Behind these everyday struggles lies a little-known system quietly shaping how you move, focus, and even learn. Tucked deep within your body, the vestibular system plays a key role in everything from reading to walking—and rarely gets the credit it deserves. It begins developing in the womb and governs your awareness of body position and your place in the world—not philosophically (“What’s my purpose?”) but literally, where your body is in space. This mechanism, called proprioception, helps you move through your environment smoothly. When it’s off, you might bump into furniture, trip often, or notice your child gripping too tightly during hugs or pressing his pencil until it snaps.
For children, an underactive vestibular system can look like poor focus, clumsiness, or trouble sitting still. For adults, it can mean frequent dizziness, nausea in stimulating settings, or feeling “off” after even a short car ride. These small disruptions can ripple into reading difficulties or fatigue—and sometimes into anxiety that seems to have no clear cause. That’s because balance isn’t just about coordination—it’s about communication between your brain, body, and inner ear.
Housed in the inner ear, the vestibular system includes three semicircular canals and two otolithic organs. The canals detect rotational movement, while the otolithic organs register linear motion and head position. Inside, the canals are filled with fluid, and the otolithic organs contain tiny calcium carbonate crystals—affectionately known as “ear rocks.” They may sound like something you’d warn your child about—“No pebbles in your ear, Andy!”—but these crystals are right where they belong. Suspended in a gel-like substance that surrounds delicate hairs, they shift as you move. The pressure they create helps your brain interpret motion and maintain balance.
While the vestibular system takes the lead in sensing motion, it doesn’t work alone. The neck plays a supporting role through what’s known as cervicogenic input—signals from muscles and joints that tell the brain where the head sits in relation to the body. When those neck muscles tighten or the cervical spine becomes misaligned, that feedback can go awry, creating dizziness or disorientation that mimics an inner-ear problem. Cervicogenic dizziness is the term often used for this neck-related imbalance, and it’s one reason you might feel “off balance” even when your vestibular system is technically sound.
The Science Explained
The vestibular system is so vital that it’s the first sense a fetus experiences before birth, and the other senses depend on it for proper integration as they develop. Take sight, for example. It’s not only about seeing near or far—it also depends on intricate neural communication between the inner ear, eyes, and brain. Developmental optometrist Dr. Douglas Stephey notes that of the roughly 3 million sensory neurons sending information to the brain, about 30,000 come from each ear and at least 1.2 million from each eye. One key function of the vestibular system is the vestibulo-ocular reflex (VOR), which keeps your eyes fixed on an object even as your head moves. When you turn your head, your eyes automatically shift in the opposite direction to stay on target. This reflex is what keeps your environment visually stable while you’re running—helping you stay oriented and on your feet. The VOR also plays a role in reading.
“Reading text on a printed page can be difficult for people with an impaired VOR because the small head motion destabilizes gaze. The result is words and letters that appear to oscillate and shift. Reading text on a computer monitor may be problematic due to heightened sensitivity to screen flickering or scrolling pages of text.”
For students, this can mean skipping lines while reading, losing their place on a page, or tiring quickly during homework. Some describe the words as swimming on the page, forcing extra effort just to keep them steady. Letters can seem to drift or bounce, making it hard to stay focused even when the eyes are trying to cooperate. Reading can start to feel like work, as the eyes struggle to stay aligned with each new line.
You may notice headaches after long periods at a screen or feel motion sick while scrolling—tiny cues that the eyes and inner ear aren’t staying in sync. Unlike a standard eye exam—where your head stays mostly still—in-depth testing of the binocular system can uncover subtle eye misalignments, including those that appear only with movement. A developmental optometrist—sometimes called a behavioral optometrist—evaluates not just visual acuity (the classic 20/20 measure), but how your eyes team, track, and communicate with your brain. If deficits are found, visual therapy, specialized lenses, or both may be recommended.
When the System Falters
Over his 37 years in practice, Dr. Stephey has witnessed a sharp rise in visual processing issues among children. The cause isn’t easy to pinpoint, but he cites several possibilities: reduced movement, disrupted circadian rhythms and sleep, toxin exposures (including mold, heavy metals, and glyphosate), ultra-processed foods, epigenetic shifts, transgenerational trauma, non-native EMF exposure, and gut dysbiosis, among others. Whatever the root cause, the result can be deeply disorienting. Kids may seem inattentive or “in their own world,” while adults describe brain fog, motion sensitivity, or a strange sense of imbalance that makes everyday movement feel uncertain.
While the causes may vary, one factor stands out across the globe: kids simply aren’t moving enough. Children are meant to move their bodies—a lot. The World Health Organization recommends that kids ages 5 to 17 get at least 1 hour of physical activity each day, and that children under 5 get 3 hours, with at least 1 of those hours being moderate to vigorous. Yet as of 2023, fewer than half (49%) of preschool-aged children assessed across 33 countries met those guidelines. Even when kids make it outside, play has changed. Playground equipment looks tamer than it once did, with “risky” structures like merry-go-rounds largely gone—often out of fear of injury or lawsuits. And once-common behaviors like climbing trees now tend to draw warnings instead of encouragement.
If your child gets the chance to hop on a playground merry-go-round—the kind kids push and jump on—there’s a lot more happening than you might think. It’s teamwork in motion as some kids run to push while others ride, and what occupational therapists call “heavy work”—pushing or pulling against resistance to build strength, proprioception, and balance. Most importantly, the vestibular system gets a workout as your little one spins, gets dizzy, jumps off, and lets her body recalibrate…before racing back to do it again. Those playful moments train more than muscles—they refine the body’s internal GPS. If your local park no longer has one, you can even find small spinner-style versions made for backyards, just enough to give kids that same dizzy joy and vestibular workout, safely at home.
That’s not to say the equipment still found where kids gather to play—slides, swings, jump ropes, and ladders—doesn’t offer value. These classics help build core strength, vestibular feedback, balance, coordination, and what’s known as “crossing the midline” —the act of moving one side of the body across to the other. When your child reaches from right to left on the monkey bars, for instance, they’re not only strengthening motor skills but also reinforcing the neural connections between the brain’s left and right hemispheres—a process essential for fluent reading.
Restoring Balance
To support your child’s balance, proprioception, concentration, and even eye development, let them do what kids naturally do. They need to roll down hills, hang upside down from monkey bars, and climb trees. This isn’t just the magic of childhood—it’s what builds the foundation for cognitive growth. A child’s visual processing system doesn’t fully mature until around age eight or nine, and even after that, these physical challenges continue to strengthen it. Teachers and parents can help prime kids’ brains and nervous systems for a more balanced, productive learning experience. Dr. Stephey explains:
“Teachers should be familiar with primitive reflexes and incorporate many of these movements for a few minutes at the beginning of the school day, and perhaps throughout the school day. I think they would be amazed by the changes in learning and behavior.”
Primitive reflexes are automatic movements present in infants—essential for early survival and development. As a baby grows, these reflexes should “integrate,” giving way to voluntary control. When they don’t, they’re known as retained primitive reflexes, and they can interfere with both learning and behavior.
Some schools embrace the connection between movement and learning, weaving physical activity into the day beyond a standard gym class. In certain Waldorf programs, for instance, students practice a choreographed movement called eurythmy, designed to support “spatial intelligence, mindfulness, and cross-lateral coordination.” Whether you’re a teacher or a parent, some exercises that can help with integrating primitive reflexes include:
- Cross-crawl march: March in place, alternately touching your left elbow to your right knee, then your right elbow to your left knee, for about one minute.
- Rocking motion: On hands and knees, gently rock forward and backward for 30–60 seconds.
- Superman hold: Lie on your stomach with arms and legs extended, lift and hold for 5–10 seconds, rest, and repeat for five rounds.
- Pencil focus: Hold a pencil at arm’s length, focus on the tip, and slowly bring it toward your nose—keeping it in focus—then extend it back out. Repeat 10 times.
Of course, it’s not just children who rely on a well-functioning vestibular system. As you age, balance becomes increasingly important due to the natural muscle loss and slower reaction times that accompany the passing years. Adults over 70 face nearly a 45% risk of a traumatic fall, the most common cause of injury in that age group. Vertigo—feeling as if you or your surroundings are moving while you’re still—also becomes more common, affecting an estimated 30% of adults over 60 who experience some form of dizziness. Even mild vestibular dysfunction can erode confidence over time—hesitating on curbs, avoiding crowded places, or feeling uneasy on uneven ground. Rebuilding that steadiness can restore far more than balance; it brings back a sense of ease in moving through the world.
That loss of confidence often begins quietly. Because dizziness can be so disorienting, it’s easy to mistake it for something more serious, like a stroke. Physical and occupational therapists—sometimes working together—can perform an evaluation called the Dix–Hallpike test to determine whether ear crystals have shifted out of place. During the test, the practitioner has you sit on a bed with your legs extended, turns your head about 45 degrees, and quickly guides you backward. If your eyes begin darting or shifting—trying to reorient in space—it’s a strong sign that those tiny crystals aren’t where they’re supposed to be.
If that’s the case, just a few sessions with a vestibular physical therapist can often resolve the problem. The most common technique for returning those “ear rocks” to their proper place is the Epley maneuver—ironically similar to the Dix–Hallpike test used to diagnose the issue. During the maneuver, your therapist will have you sit on the table, tilt your head 45 degrees toward the affected ear, and lie back for about 30 seconds. Then, your head is turned 90 degrees to the opposite side and held for another 30 seconds. Timing is crucial: move too soon, and the crystals may slip back into the wrong spot; wait too long, and they can settle somewhere else they don’t belong. (You can find a helpful demonstration video that shows how the crystals move through the canals—something that’s hard to visualize without seeing it.)
Of course, you don’t have to wait for vestibular problems to start strengthening this system. Balance exercises benefit everyone—from kids to older adults—and can easily fit into daily life. Yoga is one option; so are tools like balance boards, which come in many styles: curved like a skateboard, dome-based with a half-ball underneath, or foam-based designs that encourage microadjustments to stay steady while only a few inches off the ground. Whatever you choose, it’s wise—especially for seniors—to keep something stable nearby for support during balance work.
Whether you’re working on your own coordination, caring for an older adult you want to keep steady, or supporting a child struggling with movement, reading, or attention, finding ways to safely exercise and stimulate the vestibular system can make a real difference. If the situation is more complex, therapists trained in vestibular or visual rehabilitation—such as physical, occupational, or developmental optometrists—can design a personalized plan to meet your needs. Balance may slip quietly, but it can be rebuilt just as naturally. And if nothing else, the next time your kids are climbing a tree or swinging on their bellies like Superman, instead of calling them down to safety, you can smile—knowing you’re watching a young vestibular system grow by leaps and bounds.
