Smells That Boost Your Health

Did you know that the human sense of smell can identify thousands of aromas and is 10,000 times more precise than our sense of taste?

We have millions of smell receptors in our noses. When they detect a scent, they shoot the information to the olfactory bulb—a pea-size cluster in the brain, which sorts the signals and relays them to the limbic system. This primitive part of the brain governs many memories and emotions; some of our most basic behaviors—feeding, fighting, or fleeing; as well as sexual arousal, pleasure, and maybe even addiction. Because of their close proximity, the neurological controls for these behaviors often become entangled. That's why, for instance, during the early stages of attraction, dinner is often a prelude to sex.

It also explains how odor can help lower stress levels, improve mental and physical performance, ease pain, end insomnia, and even help us lose weight, research shows. Here’s how to use your sense of smell to your advantage.
