Tag: Lack of sun

An estimated one billion people worldwide are deficient in vitamin D, a condition largely attributed to insufficient sun exposure. The human body uniquely synthesizes this 'sunshine vitamin' when skin is exposed to ultraviolet B (UVB) rays from sunlight, making a lack of sun the primary driver for what vitamin deficiency is experienced globally.

According to the Cleveland Clinic, an estimated 50% of the world's population has a vitamin D deficiency. This common condition is directly caused by a lack of sun exposure, as sunlight is the primary source of vitamin D production for most humans.
