A lack of sunshine exposure can lead to decreased health and an increased risk of many diseases, also known as “Sunshine Deficiency” diseases

Key Points

  • 340,000 deaths per year in the United States and 480,000 deaths per year in Europe, as well as a rise in many diseases, could be attributed to insufficient sun exposure or “sunshine deficiency.”

Personalized vitamin D guidelines based on latitude and skin type could tackle deficiencies

In a recent study published in the journal Nutrients, researchers calculated indicative exposure times for maintaining vitamin D status as a function of latitude, month, and skin type, considering clear-sky and all-sky conditions for an ambulatory person in modest clothing.

What is the Real Relationship between Sun Exposure, Skin Cancer, and Vitamin D?

Several studies conclude that regular, sensible, non-burning sun exposure throughout the lifetime, and higher vitamin D levels, are related to decreased incidence of melanoma and increased melanoma survival rates

Key Points

  • Two important distinctions about the relationship between sunshine exposure and skin cancer should be made: 1) intermittent, or sudden, drastic exposure to high intensity sunlight (resulting in sunburn) does increase the risk of skin cancer, and 2) regular, moderate, non-burning exposure to sunshine (sensible sunshine exposure) has been associated with lower risk of skin cancer
  • Moderate, non-burning sunshine exposure initiates specific repair mechanisms within skin cells, including DNA repair enzymes and the production of local vitamin D, which work to prevent damage accumulation; vitamin D synthesized in the skin has several anti-cancer properties, including roles in cell differentiation, cell death, cell adhesion, and oxidative stress, all of which can help protect against the development of cancer
  • Several studies are reviewed to demonstrate how increased, sensible sunshine exposure and increased vitamin D levels are related to decreased melanoma incidence and mortality, decreased tumor size, and improved response to melanoma treatment

The sun has gotten a bad reputation because of the association between ultraviolet (UV) exposure and skin cancers.
