Does CO2 impact sleep? Yes! As CO2 levels rise, you get less and less oxygen in each breath. This can cause you to feel sleepy, tired, or less focused. At more extreme levels, carbon dioxide can give you a headache and make you feel dizzy. The primary source of indoor CO2 is you; as you breathe, you release large amounts of CO2 into the air. Use Altos to control CO2 levels around you! #Altos #yourAltos #freshair #biohackingcommunity #biohackinfo
