Scented cleaning chemicals
The use of unscented cleaning chemicals
is recommended to improve indoor
air quality. The Archives of
Environmental Health note that some
humans exposed to fragrance products
might experience some combination of eye, nose and/or throat irritation; respiratory
difficulty; possibly broncho-constriction,
or asthma-like reactions; and central
nervous system reactions (e.g. dizziness,
incoordination, confusion, fatigue).
