Perfumed things.... are they bad for us?

[cressetmama]

According to Prof x who has been all over the radio today, air fresheners, scented candles and hair spray account for 40,000 premature deaths each year. Your views?

No idea if they are bad - but many things that are bad are dose related.
Pumping frangrance into the atmosphere doesn't sound good since what is contained in frangrance is likely to be harmful in high concentrations. Hence breathing it it occasionally is likely fine but all day every day maybe not so much.
Candles are like any fire and I don't think they burn cleanly so will put soot into the house on top of frangrance.
Everything in moderation but I would panic yet!
No doubt the manufacturers of these products will do their best to smother this type of data.

Wouldn't panic
