Scientists based at the Satou hospital in Japan found that kissing worked by relaxing the body and reducing the production of histamin, a chemical that the body produces in response to pollen, causing the common symptomau clefyd y gwair including sneezing, runny nose and streaming eyes which characterise hayfever attacks.
Blood samples were taken before and after a 30 minute kissing session of 24 couples where both were sy'n dioddef clefyd y gwair. The study compared levels of histamin, and results showed that after the kissing session levels of the chemical were significantly reduced. When the experiment was repeated with cuddling but no kissing, no change was found in the levels of histamin.
Commenting on the findings, Allergist Dr Hajime Kimata of Satou Hospital in Osaka who conducted the research, said: “The results indicate for the first time that kissing may alleviate allergic responses.”
It is already known that stress can cause increased allergic reactions to allergens, suggesting that kissing has a relaxing effect, causing the reduction in histamine levels.
