Scents have a powerful influence on mood and well-being because of their direct connection to the limbic system, the part of the brain responsible for emotions, memories, and behaviour. When we smell something, Odor molecules stimulate the olfactory nerve, triggering emotional and physiological responses. This explains why certain scents can evoke strong emotions, enhance mood, or even improve mental and physical health.
