We all know somebody who’s a dedicated sun admirer – the bronzed, weathered skin is for the most part the giveaway. Currently, a study in the medical journal Cell recommends that sun exposure on a daily basis might really trigger an addictive pathway in the cerebrum, with endorphins being the underlying guilty party. Obviously, the study was carried out in mice, so we can’t be totally certain the same thing happens in human beings as well. Be that as it may, here’s evidence that sun exposure triggers vitamin D combination in the body – it’s not all that outlandish that the procedure may be addictive, especially for those who love that tanned look.
There have been studies which showed that sun-worshippers had some kind of an addiction towards the sun. Examples can be drawn from the blocking of the opioid pathway in those who sought sun tanning regularly. This often produces withdrawal like symptoms in such people. Other studies confirmed how regular sun-tanners were able to tell the difference between UV and non-UV lights in the sun beds. The new study has now concluded that endorphins triggered by exposure to UV light might be the major cause.
The Experiment to Determine Whether Sun Tanning Can Be Addictive
The mice’s backs were shaved and they were then exposed to UV light daily for about 6 weeks; which was equal to about 20-30 minutes of sun tanning exposure for human beings during the midday sun. The beta endorphin levels of the mice rose within the first week, which isn’t really surprising as the molecule is said to be generated in UV light exposure only.
The most interesting thing was that the mice became less responsive to light touching and temperature changes which hinted that there was some kind of analgesic effects due to the opioid response perhaps. Administration of opioid blocker, naloxone, also led to withdrawal symptoms in mice which is similar to those seen in human beings. Although a test to check whether the mice would prefer UV light to any other light source is still not conducted, the results are very intuitive and revealing. Researchers believe that since we need sun exposure to fulfill our body’s need of vitamin D naturally, it isn’t some outlandish guess to consider that the need can blur into an addiction. There are certainly some aesthetic rewards known for sun tanning and perhaps the tanned leathery looks are those rewards which in itself are highly addictive for all who bathe in the sunlight.
