I am doing artificial sunbathing. In fact, it doesn't matter what the room looks like, it mainly depends on the tanning bed where people lie. When people lie on it and turn it off, both sides can emit ultraviolet light after starting. The amount of ultraviolet rays is the intensity of simulated sunlight, which can't be irradiated for a long time at a time, and then the skin color will become darker. There are many such "sunshine studios" in Europe and America. Most of them sell packages, which are similar to packages in domestic health clubs or public toilets. Customers can choose to buy package tickets according to their own needs, because everyone wants to get different degrees of tanning. This kind of artificial sunbathing was very popular in Europe and America for some time, but recent research shows that too much artificial sunbathing or too much ultraviolet radiation can lead to skin cancer. Although it is not explicitly prohibited, many countries have clearly pointed out that it is not recommended. So now this sunbathing business has gradually become very deserted.
