Aurelio Rojas, cardiologist and health expert: "Kissing can be more than just good for your heart."

The act of kissing, beyond its emotional dimension and as surprising as it may be, can have measurable effects on physical health. This is what cardiologist Aurelio Rojas asserts in a recent Instagram post, where he compiles several scientific studies linking this gesture to stress reduction, blood pressure control, and the release of beneficial hormones . Far from being a poetic statement, the message is based on scientific studies and the recommendations of organizations such as the American Heart Association.

" Kissing reduces cortisol (stress) ," Rojas explains, adding that it also "lowers blood pressure" and "releases endorphins and oxytocin," two substances that strengthen emotional bonds and improve mood. These physiological effects directly contribute to protecting the cardiovascular system and reducing the risk of diseases associated with chronic stress or systemic inflammation. "Kissing can be more than just good for your heart health," says the doctor.

Furthermore, the cardiologist points out that kissing can also relieve headaches, help regulate cholesterol and calorie expenditure , and even reduce menstrual cramps and help regulate blood pressure. Although these benefits may seem hard to believe, the truth is that they are documented in scientific studies such as those in the Archives of Sexual Behavior (Wlodarski & Dunbar, 2015) and Biological Psychology (Grewen et al., 2005), cited by the doctor himself.

Rojas highlights that, taken together, these effects show that "a simple gesture activates real processes in your body, with direct benefits for your heart, metabolism, and mood." As if that weren't enough, the cardiologist explains that " when we kiss, we activate between 2 and 34 facial muscles , so kissing frequently can be like a real workout for your face and neck." Furthermore, all of this "greatly boosts collagen production, which contributes to firmer, more youthful skin ."

More science than romanticism

The content is also based on research from the Western Journal of Communication and the book Forensic and Medico-Legal Aspects of Sexual Crimes , which explore the neurological and physiological effects of common affectionate gestures. Among them, kissing stands out as one of the forms of contact that best stimulates a positive emotional response , strengthens the couple's connection, and promotes hormonal balance.

Contrary to the traditional romantic image, Rojas insists that science supports these observations . It's not about replacing medical treatments with displays of affection, but rather about valuing the positive effects that certain habits have on the body , especially in the context of prevention and comprehensive health. Her informative approach reconnects with a broad audience seeking to improve their quality of life with useful, accessible, and scientifically based information. " Don't underestimate the power of a kiss ," she concludes.
