Question: can scented candles give you a sore throat?
Answer: Formaldehyde: Plug-in air fresheners have been found to produce considerable levels of formaldehyde: a known 'human carcinogen' linked with cancers of the nose and throat. To a lesser degree it can also cause sore throats, coughs, scratchy eyes and nosebleeds. Paraffins: Most scented candles are made out of paraffin.
