Movement is Medicine

If exercise came in pill form, we would only be too eager to take our keep-fit medicine. Movement is medicine, even small doses extend longevity and can prevent and treat disease. Movement truly is a polypill.

Thinkers of ancient times, such as Hippocrates and Plato, suggested that physical activity was good for health. This has been confirmed with recent (and not so recent) studies which tell us that exercise reduces all-cause mortality risk (all causes of death), cardiovascular-related events, as well as warding off chronic lifestyle conditions such as type 2 diabetes, obesity, metabolic syndrome, dementia and cancer

Every single system in the body relies on us moving. Mental health and cognitive function, muscles and joints, hearts and lungs, hormones and mood, digestive health and gut microbiome, metabolism and blood pressure - you name it, it needs us to move frequently and purposefully to be healthy.

You can review some of this evidence on why exercise is medicine below.

“If there is any deficiency in exercise the body will fall sick.”
— Hippocrates
