Walking barefoot in the sand is much more than a simple summer activity. “It is a real wellness asset with multiple virtues for physical and mental health”, recognizes Dr. Gérald Kierzek, medical director of True Medical. Here are 10 unsuspected benefits of this entertainment, to take (very) seriously.
Sweet muscle strengthening
“Unstable sand obliges small muscles of the feet (plantar vault, ankles) and calves to work more to stabilize the body. Result: this muscle strengthening makes it possible to prevent sprains and improve proprioception”, says Dr. Gérald Kierzek.
An improved posture
“Sand walking reduces the impacts (compared to concrete, more aggressive) and encourages a natural course of the foot, limiting bad postures (vaulted back, shoulders in front)”, he underlines.
Stimulated blood circulation
“Direct contact with the sand, whether hot or fresh, activates microcirculation: it is ideal for fighting heavy legs”, reveals the doctor.
An exfoliating and softening care
“Each step acts as a natural scrub, eliminating dead skins and stimulating acupressure points under the sole of the foot”, confirms the medical director of True Medical.
A stress reducer
This direct connection to the land (called Earthing) helps lower cortisol levels. The noise of waves and sunlight amplify the anti -depression effect – thanks to the production of serotonin, the hormone of happiness “, says Dr Gérald Kierzek.
Lesser joint pain
“The flexible surface of the sand absorbs shocks, thus spanning the knees and hips. A boon for people with light osteoarthritis or convalescence after an injury”, details the doctor.
Increased energy expenditure
“Walking on sand requires up to 30 % more effort than hard soil – an excellent way to burn more calories without realizing it”, reveals the expert.
Deeper sleep
“”Earthing would regulate the circadian pace (via melatonin), especially if it is practiced at the end of the day“, Assures the medical director of True Medical.
A boost for the immune system
“”The microorganisms present in the sand reinforce the diversity of the skin microbiome, protective barrier of the body“, Specifies Dr. Gérald Kierzek.
A sensory reconnection
“Temperature, texture, sounds … Each step on the sand becomes a form of sensory meditation which reconnects at the moment present”, Note the doctor.
