Sight, sound, touch and taste are all undoubtedly important senses. Each has a crucial survival purpose, and can also bring enjoyment, wonder, relaxation and joy.
But there is no sense quite as intricate, interesting and mysterious as our sense of smell.
The olfactory bulb is the part of our brain that processes scents – and this happens extremely close to the limbic system, which deals with memory and emotion. If you have ever caught a subtle familiar scent on the breeze and been transported back to a time you barely remember, you might not find this hard to believe.
Particular scents can instantly cause excitement, disgust, calm, hunger or nostalgia, often suddenly and without warning. Our sense of smell has control over our emotions, memories, and overall health and wellbeing.
