When you kiss someone for the first time, the act of kissing will stimulate the release of the neurotransmitter called Dopamine which will surely make you crave for more. Additionally, it is this neurotransmitter that is responsible for making you lose sleep and your appetite. Now, that is the scientific explanation for the usual feeling you get when you fall in love.

Fact #2: There’s no logical explanation why people kiss.

Mouth-on- mouth, teeth-to-teeth, and saliva-to-saliva– why would many people want that? The theory of most people is we do that in order to get biological information to determine if the other person can become a good mate for us.

Fact #3: Kissing can save your life.

Fact #5: Kissing creates changes in the levels of neurotransmitters in your body.


When you kiss someone, the levels of neurotransmitters epinephrine and norepinephrine change. Such changes may lead to different physiological reactions including faster heartbeat, more oxygen in the brain and dilated pupils. The latter part may be the reason why many people close their eyes when kissing.

We have all experienced being on a high after kissing. This magical feeling is brought about by the release of endorphins that are brought about by kissing. Thank your hypothalamus and pituitary gland for this amazing feeling.

Fact #10: When two lips meet, 5 out of 12 cranial nerves are stimulated.


The reaction of cranial nerves is due to the fact that the brain is trying to collect as much information as it can about the other person. This is why many people sometimes rely on the first kiss to determine if the person he is kissing is compatible with them.

Fact #11: Kissing keeps you healthy.

Kissing does more than make us feel good. There have been studies that indicate that kissing can also help us keep healthy. It is said to boost the immune system and it can also help lower blood pressure. Additionally, the extra saliva produced when kissing can wash out bacteria from the mouth.
