Kissing isn't just a pleasurable activity; it's also incredibly beneficial for health. During kisses, partners exchange bacteria, which stimulates the immune system to combat new microorganisms, making it stronger. But that's not the only advantage of kissing.

More about the benefits of kissing, according to the Ua Health project.

Stimulate the production of a whole cocktail of hormones

During kisses, levels of oxytocin, dopamine, and serotonin rise, while the production of cortisol, also known as the stress hormone, decreases.

Kisses help relationships

In 2013, a survey showed that for women, kisses are more important for forming closeness and greater relationship satisfaction than for men.

Train the immune system

Through contact with new microbes and bacteria, the immune system is trained and learns to tame them. However, smokers have their bacteria in their mouths, and doctors advise against exchanging them. It's also not advisable to kiss when one of the partners is sick.


A kiss engages between 2 to 34 muscles in the face and neck, depending on the intensity. So, a kiss is a good exercise for toning these muscles. It's unlikely to change the shape of the face, but rather, it's just a pleasant bonus.

Negative calorie

This fact follows from the previous one - muscles are working, and calories are burned. Kissing burns between 2 to 26 calories.

Helps oral hygiene

Kissing stimulates the production of saliva, which is important for washing away food particles, bacteria, and acids. Saliva also contains substances that can inhibit the growth of bacteria and the formation of dental plaque.
