Biological mechanisms and the chemistry of kissing
The act of kissing, according to scientific research, is a complex biological activity. It involves various physiological processes, including the stimulation of sensory receptors in the lips, tongue, and skin, which then sends signals to the brain. This signal triggers the release of neurotransmitters such as dopamine, serotonin, and oxytocin, which are responsible for the feelings of pleasure, happiness, and bonding that we experience during a kiss…Read&Listen More

Kissing and public health
Kissing, as an intimate human behavior, has a profound influence on public health mainly in two ways. First, it helps in the exchange of microbiota between individuals which can boost the immune system. The act of kissing allows for the transfer of bacteria, viruses, and other microorganisms that can stimulate the body’s immunity to fight off diseases.
