Philematologists (scientists involved in the scientific study of the nature of kisses) cannot say with complete certainty why people kiss. According to the most plausible theory, this phenomenon arose as a result of the transfer of chewed food by female primates to their infants directly from mouth to mouth.
The resulting contact could be transferred to a person in the process of evolution, not only as a mechanism for survival, but also as a way to strengthen social ties and express love.
Since the time of the caveman, the meaning of kissing has changed a lot. Kissing, which we associate with courtship, helps us choose the right partner and create strong relationships through the transmission of chemical signals. All this is extremely important for achieving the ultimate goal of evolution – procreation. No wonder people stop kissing after a few years of marriage—they just don’t need to.
How kissing affects health
Kissing is inextricably linked with three senses: sexuality, which is controlled by testosteronethe pleasure for which is responsible dopamineand attachment, for the development of which it is necessary oxytocin.
The saliva we exchange during passionate kisses contains testosterone. During kissing, the body receives a dose hormones which help to generate feelings.
Kissing lowers levels of cortisol, the stress hormone. Kissing has a lasting effect – the longer you kiss, the lower your cortisol levels.
Kissing is of great importance for improving the condition of the whole organism. And not in an erotic or sexual sense at all. Lips are an unusually sensitive organ, covered with thin skin and many nerve endings that capture all tactile impulses and transmit them further.
A passionate kiss spurs growing arousal, and this, in turn, speeds up breath and pulse. The body receives more oxygen, and the raging blood spreads faster throughout the body.
When blood circulates faster, it passes through the brain faster, which captures pleasant sensations, which means they begin to stand out. endrophins. As a result, we feel euphoria and joy.
The tongue involved in the French kiss awakens the nerve endings in the mouth and the signals of pleasure passing through the spinal cord make the glands that secrete adrenaline work more actively. In addition, several thousand taste buds are located on the tongue, and with the help of smell, we feel pheromonesthat inflame our sexuality.
The pleasant feeling of goosebumps in the groin during a particularly passionate kiss is not an illusion at all. It is in the groin that the receptors on the lips and in the mouth transmit signals.
