Scents can affect emotions. Staff in health care facilities have been known to incorporate aromatherapy to help keep guests calm.

Rosemary essential oil is sometimes diffused in rehabilitation centers for its anti-bacterial and anti-viral properties.

The sense of smell can alert you to a hazardous situation. For example, if there is a fire, you smell smoke. A distinctive odor is added to natural gas so that if a leak occurs, you can identify the danger, escape to safety, and alert the appropriate authorities to deal with it. A sour or pungent aroma coming from food may inform you that it is spoiled and not safe to eat. Because smells provoke an immediate emotional response, they may help you react more quickly to the danger without having to deliberate.
In fact, sometimes a scent actually produces pain signals in the brain to communicate a possible threat. Because human emotions seem to be evocable through scent on a subconscious level, it may be possible that what you are detecting is the fear of someone else in the room. This may alert you to a threat that is present even if you don’t perceive it directly, which can give you more time to react.

They estimated that their weight was four pounds lighter when smelling floral, spicy scents and guessed they were 12 years younger than their actual age when exposed to the scent of grapefruit.

Furthermore, unlike caffeine and other drugs, such invigorating scents do not seem to produce any harmful side effects.
