Given reading on smartphones impairs cognitive function by way of reducing spontaneous sighs & thereby impairing forebrain function
Deliberately sigh (double inhale, exhale) every 2-4 minutes.
What's happening here is people are reading on the phone and for whatever reason, and I'll talk about what the likely reason is, but for whatever reason, they're suppressing their sighing And as a consequence, the brain is not getting enough oxygen and is not offloading enough carbon dioxide.
