Bad smells in the air are unpleasant and can make you feel unwell. There are various sources of odours that we perceive as stench. A smell that one person might not even notice, another person might find repulsive. The nose is a sensitive organ with an extremely individual level of sensitivity which is what makes the world of aromas so diverse and exciting. The scent in the air can also alleviate ailments, ensure that we start the day in high spirits, revive us when our energy dips in the afternoon or help us to relax in the evening. The easiest and most effective way to diffuse essential oils and other fragrances is by using an aroma diffuser.
