What we smell, aromas and odors, can have a major impact on our mood and behavior. That's what one Chicago researcher says in his new book, "Life's a Smelling Success."
The smell of baked goods is the number one thing that makes people long for their childhood. "Life's a Smelling Success" author Dr. Alan Hirsch says after that, it depends on when you were born.
He says southerners get nostalgic when they smell fresh air. In the midwest, farm animals. On the west coast, barbecue and in New England, flowers, scents that can also impact our ability to learn.
The scent of lavender can make us feel more relaxed. Jasmine, more awake and alert.
And there are flavor sprinkles that might help people who are overweight. The different smells fool their brains into thinking they've eaten more. Doctor Hirsch reports an average weight loss of 35 pounds over the course of a six-month study.
