If you think about your favorite fragrance, chances are that it will bring a smile to your face. It’s one of—if not the most—alluring things about after effects of using a body wash : their ability to change and lift our mood. One spritz of our favorite fragrance and we swear we become happier people—and it turns out there’s some scientific proof behind why certain scents make us feel happy.

Scents have a powerful impact on our mood and emotions. Studies have shown that certain aromas can help us to relax, reduce stress, and even help us focus better. Certain scents can also evoke memories and trigger feelings of nostalgia. This means that they can be used to create a pleasant atmosphere in any environment, whether it's at home or in the workplace.

Several studies have shown that the effects of various fragrances on mood, physiology and behavior are due to the fragrance’s direct and intrinsic ability to interact and affect the central nervous system. In addition, fragrances highly influence the various mental and physical conditions of human.

“Scents can have positive effects on mood, stress reduction, sleep enhancement, self-confidence, and physical and cognitive performance,” says Theresa Molnar, executive director of the Sense of Smell Institute, the research and educational arm of the perfume industry’s Fragrance Foundation.

The use of scents has been used since ancient times for therapeutic purposes and is becoming increasingly popular as people become more aware of the power of scent on our emotions.
