You're standing peacefully when suddenly… everything starts spinning. This sensation of dizziness, as unexpected as it is uncomfortable, affects many people. But did you know that the cause could be as tiny as a grain of sand? In some cases, small displaced crystals in the inner ear are responsible. The good news is that there are simple, natural, and effective ways to alleviate these sensations.
What happens in our inner ear?
In our ear, more specifically in a structure called the vestibule, are calcium carbonate crystals called otoliths. Their role? To help the body detect movement and maintain balance. They work in conjunction with sensory hairs, much like position sensors.
But sometimes, these crystals move to places they shouldn't. As a result, the brain receives conflicting information, and you feel like the room is spinning when everything is actually still. This is called benign paroxysmal positional vertigo (or BPPV).
Why do these crystals move?
Several factors can contribute to this imbalance:
Head trauma: a fall or impact can dislodge the crystals.
Aging: with age, these structures become more fragile.
Certain ENT infections: these can disrupt the balance system.
Medications: some drugs influence calcium metabolism.
Calcium or vitamin D deficiency: our diet also plays a key role!
The surprising link between vitamin D, calcium, and dizziness
There is a direct relationship between vitamin D, calcium, and balance. When the inner ear contains too much calcium or is unable to eliminate it properly, the crystals dissolve less quickly. Studies have even shown that people with osteoporosis—and therefore a calcium imbalance—are more prone to vertigo.
The solution? Ensure adequate vitamin D intake, which helps the body absorb and utilize calcium properly. A deficiency can worsen symptoms. Some healthcare professionals recommend an intake of 10,000 to 20,000 IU of vitamin D in chronic cases – under medical supervision, of course.
Good allies to combine with vitamin D:
For greater effectiveness, vitamin D benefits from being combined with:
Vitamin K2: it directs calcium towards the bones and prevents it from accumulating in soft tissues.
Magnesium: it supports the action of vitamin D and limits excess calcium.
These three elements form an essential trio to preserve the body's balance.
Simple exercises to reposition the crystals.
In addition, you can practice certain exercises that help reposition the crystals. Frequently recommended by physiotherapists, these gentle movements help guide the otoliths back to their original position.
One of the best known is the Epley maneuver, often recommended to relieve vertigo associated with BPPV.
No need to be a gymnast: it's simply a matter of tilting your head at a precise angle, remaining still for a few seconds, then changing position. An instructional video or guidance from a healthcare professional can help you reproduce these exercises safely at home.
A tiny imbalance… with very real effects.
Sometimes, a single grain of sand can throw us off balance. But with a few simple steps and a little patience, dizziness can be significantly reduced, or even disappear.
