Most public toilets in Switzerland are designed with blue light. What are the advantages and disadvantages of this design?

In daily life, if you go out, you will also use some public toilets. When you use your works, you will also find that their design concept of public toilets is different in many fields. Especially for some tourists, when they travel to some places, they will also find different places or countries, and their toilet design concepts are very different.

The design concept of the toilet is very different. For example, in this part of Switzerland, their public toilets are designed with blue light. The blue light design like this mainly means that the lights in these toilets are all blue light like this. Many people will feel particularly uncomfortable when they first enter, because some things like this blue light are not clear. So many people will feel a little creepy at first, but there is a reason for this lighting.

It is designed with blue light, and many people are particularly curious. Why do Switzerland, like this region, install some blue lights in toilets? What is the use of blue light like this? Mainly because many foreigners may be drug addicts in their daily lives, and they may make some injections or other illegal acts in the toilet. So in this case, they are also turning the light into blue light through the toilet, and lights like this are also good for controlling such things.

I can't see the blood vessels on my arm clearly because some people can't see the blood vessels on their arms clearly in this blue light, so they can't do some corresponding operations. So this is also a lamp specially designed for these addicts, and a blue light design like this is also helpful to some extent. In addition, many other countries have begun to adopt blue light design like this, which is very effective in prevention and control. Many people think that a blue light design like this may also make people feel a little bad about some ordinary people.
