Kissing can alleviate hay-fever, according to a Japanese hospital's study. The theory is that kissing relaxes you and therefore slows histamine production:
The researchers asked a total of 24 couples, where both partners suffered from hay fever, to spend 30 minutes kissing.
Blood samples were taken before and after to compare levels of histamine, and results showed that after the kissing session levels of the chemical were significantly reduced.
This was not found to be the case, however, when the experiment was repeated with cuddling but no kissing, with no change in histamine levels found.
