Apparently kissing is good for your health, especially if you suffer from allergies.
A 30-minute kissing session may suppress the body's allergic reaction to pollen, providing welcome relief from hay fever, a new study suggests.Scientists based at the Satou hospital in Japan found that kissing worked by relaxing the body and reducing the production of histamine – a chemical that the body produces in response to pollen, causing the sneezing, runny noses and streaming eyes that characterise hay fever attacks.
Must be why I don't have allergies.
I doubt it works if you're kissing yourself, MW. :)
