Happy Smells

The universal search for happiness is evident from the sales of anti-depressants hitting new highs, but maybe happiness is just a sniff away. Here are some happy smells that might make you skip that next prescription refill.

Roses or jasmine flowers - "A rose by any other name would smell as sweet..." Flower smells have been used for centuries in aromatherapy, and research at Rutgers University's Human Emotions Laboratory has confirmed that floral scents can triple the number of people's immediate happy thoughts. They can also promote more social interaction.

Lemon - The bright scent of lemon oil has been shown to improve mood, give a boost of energy and reduce anxiety. In as study at Le Moyne College, researchers found that in the presence of a lemon scent, people are perceived more positively. (Lemony perfume for the job interview might not be a bad idea.)

Lavender - In aromatherapy, lavender is one of the most used essential oils. Scientists at the University of Miami School of Medicine found that smelling it improved mood, made people feel more relaxed and actually helped them solve math problems faster. Lavender is also used to reduce anxiety and even increase sexual arousal.

Liquorice - A study at the Smell and Taste Treatment and Research Foundation showed that the smell of liquorice makes people happier, and also is the #1 smell (combined with doughnuts) that makes men more physically aroused. Liquorice has been found to increase the availability of serotonin in the brain, helping to fight depression.

Sony Comes Out with Scent Capturing Printer

Chinese designer Li Jingxuan has created a scent capturing printer for Sony as part of a student workshop sponsored by the company to identify innovative technical ideas. The printer actually uses an electronic nose sensor which detects and captures smells and then uses pattern recognition to reproduce them. It uses aroma-based inks on special postcard sized photo paper with a clear film. When the film is peeled back, the scent is released. 

Great for vacationers and foodies, the printer easily can fit in a purse or backpack. The company hasn't yet said when the scent printer will be available.
