A kiss, while normally used to show affection, actually has a lot of health benefits.

Here are 5 scientifically proven benefits of the “french” kiss.

1. Kissing relaxes

Scientist have found that kissing increases levels of oxytocin, a natural chemical in the body that assists with calming. In addition to this, kissing also releases endorphins. Endorphins are a natural hormone that increases happiness and relieves pain. When a kiss is exchanged, the saliva releases dopamine, which improves the mood.

2. Kissing boosts the immune system 

A recent study in “Medical Hypotheses” found that while kissing, there is an exchange of antibodies. Antibodies help to strengthen the immune system by defending the body against bacteria. Each exchange increases the bodies resistance. However, please caution against kissing someone who is sick, the exchange will hinder the health benefits of kissing!

3. Kissing rejuvenates the skin

According to Dr. Ava Cadell, kissing is like getting a facelift. When we kiss, we use 32 different facial muscles. Just like the body, when we stop exercising it droops and sags. The face responds the same way. Kissing is a workout for your face. Older couples who kiss often, look younger than their peers who don’t.

4. Kissing reduces allergy symptoms

Kissing reduces the emissions of IGE antibodies in the blood, which are responsible for allergy symptoms.

5. Kissing reduces the risk of heart disease

Studies show that long-time married couples, who kiss often, see a reduction in the levels of stress, cholesterol and blood pressure. When these levels are reduced, it minimizes the risk of heart disease.     Source:secretlyhealthy
