Update 2: We moved to a new bedroom and CO2 levels at night got very high again and we'd both regularly wake up at night, not optimal So I wanted to do the bathroom vent trick again, where putting the bathroom vent next to the bedroom on at night creates a low air pressure field and brings in new fresh air But the light switch was tied to the vent here so it'd blast bright light into the bedroom if vent was on, so I closed it but then it didn't help a lot. So we split the light from the vent…
🌡️ Update: 100% sleep score with bathroom fan on to keep CO2 low It sucks CO2 out of the room and creates a low pressure field that brings in new fresh air from outside the room Last time 100% sleep was in an Airbnb in Brazil we stayed which was a house built in 1970s mostly wood and very breathable, but our house is modern and very insulated So it seems it worked to improve our sleep Science supports this: high CO2 levels above 1500 cause fragmented sleep, more brief awakenings, less deep sleep and worse REM Also CO2 levels are a proxy for other air contaminants which build up in a closed bedroom so keeping it low is good We can go lower to 400-500 ppm with a real bedroom fan/vent but again this is a good start So if you're having sleep problems, check your CO2 levels
