The "Clean" Smells Encourage Clean Behavior

According to the study by Katie Liljenquist, professor of organizational leadership at Brigham Young University's Marriott School of Management, the clean smells makes people to be nice.
" People feel contaminated by immoral choices and try to wash away their sins." She says.
The experiment used the citrus-scented Windex to put in a room. The other room was unscented.
The result was that the people who were sorrounded by the flesh scented air were more likely to act fairly and charitably than those sniffing unscented air.
That is very interesting.
I've read an article about the smells affect humans before. That was about smells influence
prople's dreams. I don't remember it clearly but it was a study from German scientist.
They experimented among women, divided into 2 groups. One of them smelled the rose odoers
when they sleep, and the other slept in air that doesn't smell good.
The resulf was that those who smell the rose scented air could have good dreams, and the others had bad dreams probably because of the bad smell of the air.
