A lot of people swear by aromatherapy for emotional release. This is because aromatherapy is one of the few things we can do that has a direct impact on the mind.
You can test this theory by think of a smell that jogs a memory. For me, its the smell of old lady rose perfume. My great-grandmother always smelled like that and her bedroom was an explosion of it. Now whenever I smell some a rose scent, I'm transported back to her.
Do you have a smell like that?
Sometimes these scents are so ingrained into our brain that they cause an emotional response instead of a memory. For instance, simply think of smelling fresh peppermint and noticing how it makes you feel?
Smells can do this because they directly impact the limbic center of our brain. The limbic system is the emotional center of our body and it is responsible for the experience and expression of emotion. To think that smell can do that! It's amazing, isn't it?
