Is there a sun-tanner’s high? I’m Bob Hirshon and this is Science Update.
"Good Day Sunshine" has never been considered one of the Beatles’ drug-related songs. But Dana-Farber Cancer Institute researcher David Fisher reports that the same process that leads to the release of melanin, the skin-darkening pigment, also releases opium-like compounds called beta-endorphins. He says that may explain addictive behaviors associated with sun-bathing and tanning salons.
In other tanning news, Ohio State researchers have found that a compound in brown seaweed may protect cells against skin cancer. Whether applied topically or ingested, the chemical reduced skin cancer substantially in laboratory mice.
