The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells.
As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla (香草), and unpleasant smells such as durians (榴莲). The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water.
Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change.
Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results.
One explanation is that women’s sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.
