Sunbathing addictive like drugs?

New research on mice by scientists at Harvard University showed that sunlight stimulates the production of endorphins, a chemical that relieves pain and feels refreshing, causing mice with symptoms like addiction. This may also explain why many people cannot 'resist' sunbathing.

The conclusion was drawn by scientists from Harvard Medical Center, USA after experimenting with mice exposed to ultraviolet (UV) light in the sun with time 6. consecutive weeks. This exposure is equivalent to 20-30 minutes of sun exposure at midday summer in Florida.

Within a week, the level of endorphin in mice has increased significantly, making this animal less susceptible to pain. Later, the team gave mice an endorphin inhibitor. Surprisingly, the mice developed trembling symptoms and avoided the places where they were given the drug.

Researcher Professor David Fisher describes the impact of sunlight on mice in the experiment reminiscent of heroin addiction. Professor Fisher also said: 'The information that research provides may be valuable to educate people to limit overexposure to the sun'.

The researchers speculate that the "addictive" mechanism caused by the sun could also explain why many people can't resist sunbathing , even though they face the risk of skin cancer. . The addictive feeling of sunshine through this study also coincides with some previous studies found in people who often sunbathe can distinguish the difference between real and fake UV. .

However, some other experts questioned, the findings and tests on mice are not necessarily correct for humans.'Mice that are nocturnal animals are covered in fur to avoid light, so be cautious about deduction for human cases , ' said Dr. Richard Weller, dermatologist at Endiburgh University. He said.

People do not have to avoid exposure to the sun, only that it is not overly exposed to it, Dr. Weller added.
