I recently learned that the CDC has adopted an "Indoor Environmental Quality Policy" in 2009 that has the following text:

In addition, CDC encourages employees to be as fragrance-free as possible when they arrive in the workplace. Fragrance is not appropriate for a professional work environment, and the use of some products with fragrance may be detrimental to the health of workers with chemical sensitivities, allergies, asthma, and chronic headaches/migraines. Employees should avoid scented detergents and fabric softeners on clothes worn to the office. Many fragrance-free personal care and laundry products are easily available and provide safer alternatives.

The most interesting bits:
