Hormonal changes are the most common reason for a heightened sense of smell, especially those that occur during menstruation and pregnancy. There is also evidence to suggest that people who have lost a major sense like sight or hearing experience a heightening in their other senses to compensate for the loss.

Regardless of gender, researchers believe that people who experience high levels of anxiety may experience an increased sensitivity to smells. This phenomenon is thought to be related to the body's natural fight or flight response that puts sensory perception ahead of all else during an emergency situation. Not only can anxiety increase a person's sense of smell, but it is believed to make unpleasant smells smell worse, reducing the anxious person's tolerance. Anxious people are also better able to identify the type of smell they are experiencing.Learn More
