Vitamin D, sun, sunbeds and health

Area of Science:

• Dermatology
• Public Health
• Endocrinology

Background:

• Ultraviolet (UV) radiation from sun exposure and artificial sources like sunbeds is a primary source of vitamin D.
• Low vitamin D levels are prevalent, particularly among fair-skinned young populations in northern latitudes.
• Sufficient vitamin D status is linked to numerous health benefits.

Purpose of the Study:

• To review the health effects of solar radiation, sunbeds, and vitamin D.
• To evaluate the association between UV exposure, vitamin D status, and the risk of cutaneous malignant melanoma (CMM).

Main Methods:

• Literature search of MEDLINE database for studies published between 1981 and 2011.
• Inclusion of studies reporting relative risk for CMM associated with sunbed use, vitamin D, and UV effects.
• Analysis of data from diverse populations across different latitudes and age groups.

Main Results:

• UV radiation is the main source of vitamin D, essential for health.
• Despite identified health benefits, UV exposure is linked to an increased risk of CMM.
• Young individuals with lighter or pigmented skin in Northern Europe often exhibit insufficient vitamin D levels.

Conclusions:

• The health benefits of achieving adequate vitamin D levels may surpass the potential increase in CMM risk from moderate UV exposure.
• Careful consideration of UV exposure is recommended, balancing vitamin D sufficiency with skin cancer risk.
• Scientific evidence supports the assessment of overall health benefits versus CMM risk.
