One of the things that intrigued me about the Withings Body Analyzer was that it measured levels of CO2 and temperature. According to Withings, CO2 can build up in confined spaces, like your bedroom. Excess levels of CO2 are not good for your health and can cause problems that affect sleep, induce headaches, and cause dizziness among other health problems.
I noticed that the levels over night were high, so I started playing around with opening windows and doors to get to the perfect levels. To be quite honest, I haven’t noticed any difference, but it was fun just playing around with it ☺
