But co2 can and will cause headaches at levels it’s easy to find indoors
Based on experience?And make sure you don’t exhale too much.
co2 really isn’t that bad. I’d suspect something else before co2. Carbon monoxide, definitely serious though.
And co2 sinksAll I know is I'm still getting headaches, but being as my wife and kid seem to be fine, I'd guess it was stress related. Although I do go downstairs to the "basement" (fish room) WAY more often than them, which is with the furnace and water heater are, so who knows.
