Blue Lights Cut Train Station Suicides

Blue lights at train stations saved thousands of lives in Japan. Metro officials installed these

calming blue LEDs at platform edges after studying suicide prevention methods. The result was shocking.

An 84% drop in suicide attempts at stations with blue lighting. The color blue triggers a psychological

response that reduces impulsivity and anxiety in crisis moments. When someone stands

at a platform edge contemplating the worst, that blue glow creates a pause long enough

to reconsider. Other countries noticed. Europe and North America started

installing them too. Critics argue it just moves the problem elsewhere,

but data shows it genuinely prevents deaths, not just relocates them.
