How keeping CO2 low with a bathroom fan gave me 100% sleep score
🌡️ 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
