Sand presents a physical challenge through instability and resistance. The original article also describes a practice known as grounding, or earthing: direct contact with the Earth's surface, said to allow an exchange of electrons between the body and the ground. It discusses research suggesting possible health benefits.
Reduced inflammation and pain
The article cites research in the Journal of Inflammation Research (2012), describing the hypothesis that direct ground contact allows free electrons to neutralise free radicals in the body, potentially reducing inflammation and pain.
Sleep and mood
Regular grounding is also associated in the original text with improvements in sleep quality and mood. It refers to a study in the Journal of Environmental and Public Health (2012) in which participants reported improvements in sleep quality, muscular tension, menstrual pain and stress.
Cardiovascular health
The article refers to research in the Journal of Alternative and Complementary Medicine (2013) linking grounding with circulation and blood viscosity, and discusses possible implications for cardiovascular function and disease prevention.
Health and wellbeing
The original BFT approach combines exercise with a natural sand environment, aiming to offer more than physical conditioning. Its programmes emphasised direct contact with sand through barefoot exercises and activities such as yoga and stretching.
Integration into Beach Functional Training
Within the original BFT concept, sand is presented as a natural conductor supporting grounding during exercise. The article proposes that combining this contact with training may contribute to muscular recovery and general wellbeing.
