You may not fully understand the meaning of “tongue to tongue” kissing, but it is somewhat similar to sharing a meal, like eating oats. Sharing saliva and exchanging breath creates a strong bond that should be handled with care.
Kissing is an act that has existed for thousands of years. It is not unique to humans—many mammals and animals have been observed displaying similar behaviors. Kissing brings many benefits, which may be why nature gifted this act to humanity.
Here are some of the reasons why people kiss:
1. Kissing for happiness
Kissing is a way for two people to express love, whether between partners, relatives, or close friends. When we kiss, the body produces endorphins—hormones that bring happiness—leaving both people feeling warm, joyful, and carefree. Kissing also helps lower cortisol levels, making it an effective natural remedy for stress.
2. Kissing to excite and satisfy
Kissing triggers the release of dopamine, a hormone linked to the brain’s reward system. Dopamine is produced when we experience something we enjoy, like a delicious meal. When we kiss someone we like, dopamine helps us feel happy, content, and excited. Research shows that dopamine levels rise during intimacy until sexual climax is reached, after which prolactin replaces it, helping calm desire. In women, prolactin is involved in milk production and often reduces sexual desire during breastfeeding. In men, it works with other hormones to support sperm production.
3. Kissing to strengthen bonds
When couples kiss and their tongues gently intertwine, oxytocin levels increase. Oxytocin is a hormone that helps build emotional bonds and also plays a role in childbirth and breastfeeding.
4. Kissing to burn calories
Kissing engages the orbicularis oris muscle group around the mouth, as well as up to 33 other muscle groups. It also activates at least five pairs of nerves, including those responsible for smell, facial movements, and tongue control. Because so many muscles and nerves are involved, kissing for one minute can burn up to 26 calories. To enjoy longer kisses, good oral hygiene is important.
5. Kissing to arouse
Kissing stimulates nerve endings and helps produce happiness hormones. It can also transfer testosterone from men to their partners. Since testosterone boosts growth, cell repair, and libido, kissing—especially French kissing—can increase arousal. Combining kissing with hugging and other forms of touch can enhance this effect.
While kissing offers many benefits, it can also spread illnesses if one person is unwell. Conditions like the common cold, hepatitis B, herpes, and warts can be transmitted through kissing. Therefore, it’s wise to avoid kissing if you have any of these infections to protect your loved ones’ health.
Let’s strive to kiss wisely and responsibly.
