LM: #318: Carbon pomodoro
Need a break? Maybe it’s not time, but air quality.
I recently tried monitoring the air quality in my home office with an air quality meter (bought on Amazon). I’ve since developed a new routine that helps me stay focused.
Surprisingly, even in an 11-foot square room, with vaulted ceiling, my own breathing increases the CO₂ levels quickly. I’m above 1,000 ppm within a couple hours.

If I step outside, or even stick my head out the window, I can instantly think more clearly.
One study has found that a CO₂ level above 1,000 ppm reduced six of nine measures of decision-making performance.
So I’ve started working in oxygen intervals. Once the meter reaches 1,000 ppm, I open a window and take a quick walk. Fifteen minutes later, the CO₂ level is back below 600.
Even if you don’t have a meter, you may find you think better with a little fresh air.
