Kissing involves a complex interplay of physical, emotional, and potentially social elements. It's more than just a simple lip-to-lip contact.
Physical Aspects of Kissing
- Muscular Engagement: Kissing primarily uses the orbicularis oris muscle group surrounding the mouth, but up to 33 other muscle groups can be involved depending on the type of kiss. [Reference: Kissing mainly involves the use of the orbicularis oris muscle group surrounding the mouth, along with up to 33 other muscle groups utilized when kissing.] This muscular activity can even burn calories; a one-minute French kiss can burn approximately 26 calories. [Reference: With so much involved, it has been found that French kissing for one minute can burn up to 26 calories.]
- Sensory Input: Kissing involves a significant amount of sensory input. The lips are highly sensitive, providing tactile feedback and information about temperature, pressure, and texture. Taste and smell also play a role, contributing to the overall experience.
- Microbial Exchange: Kissing facilitates the exchange of saliva and consequently, microorganisms. This can have both positive and negative health implications, ranging from the transfer of beneficial bacteria to the transmission of certain viruses and bacteria. [Reference: Kissing offers many health benefits, but may also transmit a small number of disease-causing bacteria and viruses.] Studies have even shown that intimate kissing shapes the oral microbiota. [Reference: The variation of microbial communities associated with the human body can be the cause of many factors, including the human genetic makeup...]
Social and Emotional Aspects of Kissing
Kissing carries significant social and emotional weight. It's often associated with:
- Intimacy and Affection: Kissing is a common expression of love, affection, and intimacy between partners.
- Romantic Relationships: It frequently plays a role in courtship and romantic relationships, serving as a form of nonverbal communication and bonding.
- Social Norms and Cultural Variations: The practice and meaning of kissing vary significantly across different cultures and social contexts.

The examples provided in the references illustrate the diverse contexts in which kissing occurs, from romantic relationships to medical cases involving “kissing aneurysms.” [Reference: We herein report a case of successfully embolized 'kissing aneurysms' arising at the proximal junction of the fenestrated distal basilar artery.] Even the veterinary world uses the term to describe a condition of the spine. [Reference: Jul 29, 2019 ... The locations and number of vertebrae involved can vary. Kissing spines most commonly occur between thoracic vertebrae (T) 13 and 18, with T15… ] The variety of contexts highlight the multifaceted nature of the act.
