Women who visit tanning beds in order to bronze their skin during the colder months are putting themselves at risk of skin cancer. Also, they are accelerating the aging of their skin, particularly in the neck area, which typically doesn't get direct contact with UV rays.
A team of researchers at the University of North Carolina, Chapel Hill, report on one more reason why daylight is better than a tanning salon.
Apparently, the earlier hours of the day are safer for people to be out and about, in terms of skin cancer risk. This effect isn't directly due to the sun, however, but a person's circadian rhythms. In a mouse model, the researchers found that the nocturnal creatures were more susceptible to skin damage in the morning. Since people are diurnal, the researchers concluded that the opposite is likely true in humans.
"Our research would suggest that restricting sunbathing or visits to the tanning booth to morning hours would reduce the risk of skin cancer in humans," said senior study author Aziz Sancar, M.D., Ph.D.
In addition to limiting sun exposure, women may be able to keep neck skin firm by using the best neck creams on the market.
