The field of psychology had a big crisis in the 2010s, when many widely accepted results turned out to be much less solid than previously thought.

How does air pollution impact your brain?

news.ycombinator.com Written By 2025-09-28 22:04:23

Image credit: Ionut Stefan We’ve known for some time that air pollution is bad for human health. However, the focus was mostly on the lungs, and to some extent, the heart. After all, airborne pollutants are inhaled through the lungs and can reach the heart through the bloodstream, so it’s not surprising these take the brunt of the damage. But somewhere along the way, it became somewhat mainstream to consider how air pollution might affects brains too. What I found surprising was the recency of

Altered states of consciousness induced by breathwork accompanied by music

These states include components such as euphoria, bliss, and perceptual differences. However, the neurobiological mechanisms underlying the profound subjective effects of high ventilation b
