Smell is the strongest of the senses and is best able to influence brain activity. Olfactory bulbs are part of the limbic system and directly connect to the areas of the brain that process emotion and learning, “This is one of the reasons why so often something that we smell will trigger a memory or remind us of something or someone,” says Beverley Hawkins, owner of the Vancouver-based West Coast Institute of Aromatherapy.
Essential oils not only help improve health, but it can strongly improve mood. Improving mood can increase productivity, improve relationships, and boost overall levels of happiness.
“Essential oils have anti-viral, anti-bacterial and anti-fungal properties and using them in an environment where there are a lot of people can help to keep germs at bay,” says Hawkins. Inhaling essential oils activates the hypothalamus – the area of the brain which sends messages to other parts of the body. “A simple inhalation of an aroma can cause many changes in the body,” says Hawkins, including activating the immune system, affecting blood pressure and stimulating digestion.
