There is weak evidence that negative air ionization via air filters is associated with lower depression scores, particularly at the highest exposure level.

TLDR: negative ions may have slight positive effects on general mental health but we can’t produce negative ions without harmful waste gas (ozon). The best way to get your dose of negative ions is go outside, preferably close to waterfalls

Wow! Good find

It’s interesting, some customs around the world talk about waterfalls and specifically spending time next to them or under them. I wonder if this could be an empirical basis for a local custom?
