Lighting the streets with blue light instead of white, orange or yellow could reduce both the number of suicides and the crimes committed . Although there are still not enough scientific studies to confirm it, several cities have decided to put this measure to the test. The Japanese Railways company C entral Nippon Expressway Co began to install LED panels in Japan last year to project blue light on its platforms, in order to discourage people from trying to kill themselves by jumping onto the tracks. . And those responsible say that, for now, the measure has reduced the suicide rate by up to 20%.
On the other hand, in the city of Glasgow (Scotland) they decided a few years ago to illuminate certain streets with blue tones, a measure that, according to the Police, has generated a 9% decrease in crimes committed in those areas compared to the rest of the city. town.
Despite these results, Tsuneo Suzuki, a professor at Keio University (Japan) says that, although several scientific studies show that blue has a calming effect on people , from there to affirm that it can deter someone from committing a crime or commit suicide there is a big step.
