Scientists tanning is addictive

Scientists believe that UV rays penetrating the skin, are addictive, similar to heroin.

Experts from Harvard claim that exposure to sunlight stimulates the body to produce endorphins, chemicals that relieve pain, create a tide of well-being and make us feel good. Mouse, for example, had a reduction in pain under the sun, and when they are deprived of the opportunity "to the sun, the rodents showed the presence of withdrawal. This discovery helps explain human habit to tan, despite the threat of getting skin cancer.





A team of researchers from Harvard medical school gave the mice a daily dose of UV radiation for six weeks. The amount was the equivalent of being in for 20 to 30 minutes in the hot Florida sun at noon. During the week, the levels of endorphins in animals has increased and they have become less sensitive to pain. Then the mice were given a drug that reduces the effectiveness of endorphins, and they quickly began to develop symptoms of withdrawal, such as trembling and the sound of teeth. They also tried their best to avoid the place where they were given the drug. Professor David Fisher described the action of sunlight as the "shot of heroin", but weaker. He added: "This information can serve as an important means of educating people to curb excessive sun exposure".
