The tongue: what really happens when we engage in a tongue-to-tongue kiss…
The Tongue and What Really Happens When We Kiss
You might not fully grasp what kissing “tongue to tongue” means, but think of it as something oddly intimate—like sharing a warm bowl of oatmeal. It may sound strange, but at its core, it’s about connection—an exchange of breath, saliva, and emotion that forms a deep and powerful bond.
Kissing has been around for thousands of years, and it’s not just a human behavior. Many animals, especially mammals, display similar forms of affection. So what is it about kissing that makes it so special—and why do we do it?
Let’s explore a few fascinating reasons people kiss:
Kissing for Happiness
Kissing is one of the purest ways to express love—whether it’s between lovers, family members, or close friends. When we kiss, our bodies release endorphins, the so-called “happiness hormones,” which flood us with warmth, joy, and emotional connection. Kissing also helps lower cortisol levels, relieving stress and creating a moment of peace in a busy world.
Kissing for Excitement and Pleasure
Dopamine, the brain’s “reward” hormone, is released during a kiss—especially with someone we’re attracted to. This hormone gives us that rush of excitement and satisfaction, similar to what we feel when enjoying a delicious meal. As kissing becomes more intimate, dopamine levels climb, leading toward sexual arousal. Afterward, prolactin takes over, calming us down. In women, prolactin is linked to milk production and can reduce libido during breastfeeding. In men, it works with other hormones to aid sperm production.
Kissing to Strengthen Bonds
When couples kiss deeply, oxytocin—often called the “love hormone”—is released. Oxytocin fosters trust and deep emotional bonding. This same hormone also helps mothers during childbirth and breastfeeding, showing how essential it is in building intimate connections.
Kissing Burns Calories
Believe it or not, kissing isn’t just romantic—it’s a mini workout! A kiss engages 34 facial muscles and activates at least five cranial nerves, including those involved in touch, smell, speech, and even voice control. A passionate one-minute kiss can burn up to 26 calories. Just another reason to keep those kisses coming (and maintain good oral hygiene)!Kissing and Hormone Exchange
One lesser-known benefit of kissing is the transfer of testosterone—especially from men to women or between men. Testosterone plays a key role in libido, muscle growth, and cell regeneration. French kissing, especially when paired with hugging and body contact, can boost arousal and ignite passion.
A Note of Caution
While kissing has many benefits, it can also spread illness. If either person is unwell—especially with colds, herpes, hepatitis B, or warts—it’s best to hold off. Protecting your health and that of your loved ones is a form of love too.
In the end, kissing is more than just a romantic gesture—it’s a biological, emotional, and psychological experience rolled into one. Whether for bonding, healing, or simply sparking joy, it’s truly a gift from nature.
