and these are the surprising facts, captured
UK’s The Sun.
1. It increases life expectancy
Men who kiss their wives in the morning live
five years longer than men who don’t.
2. It prevents tooth decay
Kissing increases the mouth’s production of
saliva, which helps to clean the mouth and
prevent tooth decay.
3. We swap more than just germs
We swap an average of 9ml of water, 0.7mg of
protein, 0.18mg of organic compounds, 0.71mg
of different fats and 0.45mg of sodium
chloride when we lock lips.
4. But there are still A LOT of germs involved
One millilitre of saliva contains about
100,000,000 bacteria.
5. It actually burns calories – get kissing,
ladies
Couples can burn anywhere between 2 and 26
calories per minute while kissing and can use
up to 30 muscles.
6. We do a lot of it
The average person will spend an estimated
20,160 minutes of their lifetime kissing. That’s
336 hours, or 14 whole days.
7. Some more than others, it seems
The longest kiss ever recorded was 58 hours,
35 minutes and 58 seconds – nearly two and a
half days.
8. Our brains know how to find our lovers lips
Sixty-six per cent of people close their eyes
during a kiss. Our brains have special neurons
that help us to locate each other’s lips in the
dark.
9. It can stop us falling ill
There is some evidence, from past studies, to
suggest that kissing provides us a means of
protecting ourselves from certain viruses.
10. It’s more than just fun – it’s stress
relieving
Holding hands and kissing reduces levels of
the stress hormone cortisol, thereby lowering
blood pressure and optimising immune
response
11. There’s a scientific reason for why we
want more
When you kiss someone for the first time you
get a spike in dopamine, which makes you
crave more.
