Knowing the history of how sunlight exposure has been utilized to cure disease and improve health is important for understanding why it is still so essential today
Major changes in the way we live, especially over the past century, have affected the amount of sunshine we are exposed to on a daily basis, which for most people, is minimal. These days, most work is done indoors, digital devices have become a popular form of indoor entertainment, and air conditioning makes being indoors on a hot and sunny day easily attractive. Negative messages about the sun and skin cancer, even tanning, have scared people into staying indoors or covering up at all times when going outdoors, to the point where the body is unable to reap the benefits of sunshine and UV exposure. The “Diseases of Darkness” that are associated with vitamin D deficiency, such as rickets, and other negative health effects resulting from a lack of sun exposure still exist today, and yet are absolutely avoidable and unnecessary. In fact, in 2012 the UK cited 833 hospital admissions for rickets, more than four times the amount 10 years earlier.
