Physical balance is the ability to maintain the body’s center of gravity above its base of support, both statically (when standing still) and dynamically (while walking or playing sports). It relies on the constant integration of three complementary sensory systems: the vestibular system (inner ear—detects head movements and accelerations), proprioception (muscle, tendon, and joint receptors—provide the brain with information about the position of each body segment in space), and vision (visual cues from the environment). The cerebellum and brainstem integrate this information in real time and constantly adjust muscle tone. A deficit in any of these systems—peripheral neuropathy, vestibular disorder, visual impairment, or muscle fatigue—impairs stability and increases the risk of falling. Dizziness and balance disorders can be assessed in the dedicated section.
Balance naturally declines with age—after age 65, one in three people falls each year, and falls are the leading cause of accidental death among those over 65 (HAS). Several factors accelerate this decline:
Balance training is effective at any age and produces measurable results within a few weeks. The most clinically validated exercises for improving stability include tai chi (a 37% reduction in fall risk in meta-analyses), yoga, single-leg exercises (standing on one leg for 10 to 30 seconds, with eyes open and then closed), and Nordic walking (which stimulates overall proprioception). Swimming and cycling maintain coordination without putting stress on the joints.
Nutritionally, magnesium (300 mg/day) plays a role in neuromuscular transmission—a deficiency leads to cramps, muscle weakness, and instability. Vitamin D3 (at least 1,000 to 2,000 IU/day for seniors—blood test recommended) has been shown to improve muscle strength and reduce the risk of falls. Omega-3 EPA-DHA supports neurological health and the conduction of proprioceptive nerve impulses. Ginkgo biloba (EGb 761 standardized extract—well-established use according to the EMA) improves cerebral microcirculation and alleviates dizziness associated with vascular-related balance disorders—contraindicated with anticoagulants and antiplatelet agents. In cases of persistent dizziness, repeated falls, or a sudden onset of balance disorders, consult a doctor to rule out a treatable neurological or vestibular cause.
