Humans perform as well or better when exposed to high vs low CO2 concentrations says new study

Humans perform as well or better when exposed to high vs low CO2 concentrations says new study

A new paper finds the performance of test-taking (cognitive, decision-making) “astronaut-like” subjects exposed to 5000 ppm CO2 was “similar to or exceeded” the performance of those exposed to baseline (600 ppm). This study follows up on a 2018 paper that determined submariners exposed to 15000 ppm CO2 performed just as well as subjects exposed to 600 ppm. Those of us who own CO2 monitors know that indoor (bedroom) CO2 concentrations typically vary between about 600 ppm during the day and 1000 ppm overnight – the latter earning a frowny face air quality rating.
