Take heed all you sunbakers!

"Melanoma is related to intermittent, excessive sun exposure, such as that experienced during recreational activities and holidays. Melanoma is also related to sunburn in childhood and adolescence.
There is no health advantage from levels of ultraviolet exposure that result in tanning or burning. This is the case whether the untraviolet radiation is from the sun, or from sun beds or lamps. Some suggest that if we become too vigilant about sun exposure, then we may become vitamin D deficient. However, the truth is that our vitamin D requirements can usually be met with exposure to the sun during short periods outdoors such as usually occur in everyday life.
In summary, the way to prevent skin cancer is to reduce excessive exposure to ultraviolet radiation. A change in attitude towards tanning would be an excellent start."
