Here is why you should open your
#windows whenever you can. On the left, is 2:05 PM when Iโve had the windows closed all day, the
#CO2 levels in the house are high, indicating poor
#ventilation. Now swipe to the right image, the levels have dropped to a third after leaving the windows open for over 2 hours, indicating excellent ventilation. High CO2 levels indoors can cause various
#health issues including
#tiredness,
#headaches,
#eye #irritation,
#dizziness and/or
#difficulty #concentrating, so please check your levels inside your house. I borrowed this CO2 monitor as well as an
#AQI monitor from my local
#library
