Does the Heart Really Feel Love?

Love has been one of the most mysterious emotions that humans experience, and its origin has been an enigma since the beginning of time. People often have a hard time explaining what love is or how it works because it is not something that can be easily described or explained. It is often thought of as an emotion that is felt within the heart, but is this really true? Does the heart really feel love? In this blog post, we will explore this question and delve into the science behind love.

The Concept of Love

The concept of love has been associated with the heart for centuries. From Shakespeare’s iconic line, “My heart is and always will be yours,” to modern-day love songs that often sing of the heart’s desire, it seems like the heart has always been seen as the centre of love. But is this just a romantic cliché or is there some scientific basis to it?

Love and the Brain

Well, interestingly, there might just be. Research has shown that during the intense feeling of romantic love, the brain releases several hormones such as dopamine, oxytocin and serotonin! These hormones regulate certain bodily functions such as emotions, mood, appetite, blood pressure, and even pain.

The Heart’s Involvement

But what about the heart’s involvement? Does it play any role in love? Well, biologically, the heart is simply a muscular organ that pumps blood throughout the body. However, it may be a stretch to say that love resides solely in the brain and not the heart.

The Feeling of Love

Many people may describe the feeling of love as “fluttering” or “pounding” in the chest, which could be interpreted as the heart being involved in the sensation. A study published in the American Journal of Medicine in 2015 found that people who fell in “romantic love” had increased activity in the heart’s ventricles.

The Heart and the Brain Connection

Moreover, the heart and the brain are closely intertwined through the vagus nerve, a long nerve that runs from the brain down to the abdomen. The vagus nerve allows communication between the brain and the heart and may play a role in the physiological changes that occur during the feeling of love.

Love: A Multi-Dimensional Experience

We should also keep in mind that love is more than just a physical sensation. It is a complex emotion that encompasses many different feelings such as desire, compassion, empathy, and more. Being in love can also affect mental and emotional states, such as self-esteem, self-confidence, mood, and happiness. So, the heart may not be the only organ involved in love, but rather, love is a multi-dimensional experience.

Scientific Investigation

In an attempt to answer this question, scientists have turned their gaze to the mysterious mechanics of love. Utilising technologies like fMRI scans, they have attempted to pinpoint the physiological responses to love and the areas of the brain that are activated when one is in love.

Love and Hormones

It’s been established that hormones play a significant role in the way we experience love. Oxytocin, often dubbed the ‘love hormone’, is released during physical contact or emotional bonding and is essential to the formation of strong romantic relationships.

The Role of Dopamine

Dopamine, another hormone, is also intricately tied to the experience of love. It is associated with feelings of euphoria, motivation, and reward, which are all common feelings in the early stages of romantic love.

Serotonin Levels

People in love have also been found to have lower levels of serotonin, which is similar to people with Obsessive-Compulsive Disorders. This could account for the obsessive thoughts many people have when they are in love.

Love and Pain

Interestingly, research has shown that the same areas of the brain that light up when we are in love, are also activated when we experience pain. This could potentially explain why love can sometimes feel painful or why heartbreak can feel so devastating.

The Heart’s Physiological Response

While the brain may be the major command centre for love, the heart does have a physical response. When we see a loved one, our heart rate often increases, and we might even feel our heart “flutter.”

Cortisol and Love

During the early stages of love, stress hormones like cortisol also spike. This rise in cortisol levels can lead to feelings of nervousness and the ‘butterflies’ in the stomach feeling.

Long-Term Love

The intense feelings associated with the early stages of love tend to fade over time. As romantic love evolves into long-term attachment, different brain areas are activated. These areas are associated with bonding and attachment.

The Role of Vasopressin

In long-term love, the hormone vasopressin plays a significant role. It is associated with behaviours linked to long-term bonding and relationships, like nest building in voles.

Experience of Love

The experience of love is highly individualised and can vary greatly from person to person. Factors such as personal beliefs, past experiences, and individual personality traits can all influence how one experiences and expresses love.

Affect on Mental Health

Being in love can also have a profound impact on mental health. It can affect mood, motivation, and energy levels. Positive relationships can provide support and enhance mental well-being, while toxic relationships can have the opposite effect.

Love and Attachment Style

One’s attachment style, largely determined by early life experiences with caregivers, can also play a role in how one experiences love. There are typically three types of attachment styles – secure, anxious, and avoidant, each impacting relationship dynamics and feelings of love.

Love and Personal Growth

Love can also be a powerful catalyst for personal growth. Through relationships, we can learn more about ourselves, our desires, and our capacity to care for others.

Cultural Influence on Love

Cultural factors also play a role in how we experience and express love. Different cultures have different beliefs and customs around love and relationships, which can influence our understanding and experience of love.

Love’s Evolutionary Purpose

From an evolutionary perspective, love might serve a purpose in survival and reproduction. The formation of intimate bonds could ensure cooperative child-rearing and mutual support, thus promoting survival of the species.

The Dark Side of Love

But love isn’t always rosy. It’s important to acknowledge the darker sides of love, including obsession, heartbreak, and loss. These experiences, while painful, are also a part of the complex landscape of love.

The Mystery of Love

Despite all the scientific exploration, love remains a mystery. It is a deeply personal, complex, and multifaceted experience that can’t be wholly defined or explained by biology alone.


Love, in all its complexity, continues to captivate and confound us. Though we may not fully understand it, its profound impact on our lives is undeniable. While the heart may not be the seat of love as we traditionally thought, it’s clear that love is more than just a feeling – it’s a physiological process involving many parts of the brain and body.

Final Thoughts

So, if anyone asks you where love comes from, you can confidently answer, “The brain… and more.” Love, it seems, is a truly holistic experience, engaging not just our hearts, but our brains, bodies, and perhaps even our souls.


In conclusion, does the heart really feel love? The answer to this question is quite complex. Although the heart does not actually “feel” love biologically, it may play a significant role in the physiologic and physical experience of love. The feeling of love is the result of numerous complex processes happening in both the brain and various organs in the body. In essence, love is not limited to just one organ or part of the human body but is an interconnected experience that involves the brain, the heart, and so much more. So, the next time you feel those “butterflies” in your stomach or that “pounding” in your chest, remember that love is truly just an amazing and profound human experience that encompasses us in every way!
