No Smoking
Thankfully in recent years tobacco use rates have generally declined, but if you are still partial to the odd cigarette, you should probably smoke it outside. Why? Well, apart from the obvious health issues associated with smoking, not only are there around 7,000 plus chemicals found in cigarette smoke but those toxic airborne tobacco particles remain at harmful levels for up to five hours.
And it’s not just cigarettes, anything you burn in your home, like incense sticks or candles, emit carbon monoxide and carbon dioxide into the air. Incense sticks actually emit over 100 times the number of fine particles than your average candle.
