Heartache: An Emotion Or A Physical Pain?

Heartache is a very real phenomenon, both as an emotion and a physical sensation. The term heartache is more than a metaphor, describing the experience of both physical and emotional pain. When we feel heartache, we are experiencing a blend of emotional stress and stress-induced physical sensations such as muscle tightness, increased heart rate, abnormal stomach activity, and shortness of breath. Research has shown that the same regions of the brain that become active in response to physical pain are also activated during intense social rejection or loss. Social rejection and physical pain are rooted in the same regions of the brain, and the pain we feel from heartache is no different from a stab wound.

Heartache can lead to changes in eating habits, reduced motivation, anxiety, and depression. It can be a debilitating experience, with some people even suffering strokes or heart attacks due to the stress of a breakup. The effects of heartache can be mitigated by staying active, maintaining healthy eating habits, and engaging with one's social circle.

Is heartache a physical pain?

Heartache is a very real physical pain. When we experience heartache, we are quite literally feeling a blend of emotional stress and stress-induced physical sensations, such as muscle tightness, increased heart rate, abnormal stomach activity, and shortness of breath. Emotional pain involves the same brain regions as physical pain, suggesting the two are inextricably connected.

The Science of Heartache

Recent studies have shown that activity in a brain region that regulates emotional reactions, the anterior cingulate cortex, helps to explain how an emotional insult can trigger a biological cascade. During a stressful experience, the anterior cingulate cortex may respond by increasing the activity of the vagus nerve, which starts in the brain stem and connects to the neck, chest, and abdomen. When the vagus nerve is overstimulated, it can cause pain and nausea.

In one study, heartbroken individuals were placed in an fMRI machine and shown pictures of their ex-partner. They trembled, cried, sighed, and got angry, and in their brains, these emotions triggered activity in the same area associated with physical pain. Another study that explored the emotional-physical pain connection compared fMRI results on subjects who touched a hot probe with those who looked at a photo of an ex-partner and mentally relived that particular experience of rejection. The results confirmed that social rejection and physical pain are rooted in the same regions of the brain.

The Evolutionary Function of Heartache

The ""social pain" of separation likely served a purpose back when our ancestors lived on the savannas. There, safety relied on numbers, and exclusion of any kind signalled death, just as physical pain could signal a life-threatening injury. Psychologists reason that the neural circuitries of physical pain and emotional pain evolved to share the same pathways to alert protohumans to danger. Physical and emotional pain, when predators lurked in the brush, were cues to pay close attention or risk death.

The Physiology of Heartache

The pain of heartache may be caused by the simultaneous hormonal triggering of the sympathetic activation system (most commonly referred to as the fight-or-flight stress response that ramps up heart and lung action) and the parasympathetic activation system (known as the rest-and-digest response, which slows the heart down and is tied to the social-engagement system). In effect, the heart's accelerator and brakes are pushed simultaneously, and those conflicting actions create the sensation of heartbreak.

The Impact of Heartache

The impact of heartache can be incredibly disruptive, creating a stress response that leaves us reeling from the initial shock of a breakup. The stress hormone cortisol can cause digestive problems, aches and pains, and a loss of appetite. The broken-hearted also crave the neurotransmitter and hormone dopamine, which produces the sensation of ecstasy, energy, drive, and focus.

Is heartache a metaphor?

Heartache is a complex human experience that blurs the boundaries between the emotional and the physical. While it is often referred to as a metaphor, the experience of heartache goes beyond mere figurative language, as it involves very real physiological and neurological responses.

Heartache, or heartbreak, is a term used to describe the intense emotional stress and pain one feels when experiencing great loss, often in the context of unrequited or lost love. This concept is cross-cultural and universal, with many languages using similar expressions that translate to "heart pain." The experience of heartache is so profound that it has been recognised since ancient times, with references to broken hearts appearing in Sumerian proverbs and Biblical texts.

The question of whether heartache is a metaphor or not is a nuanced one. On the one hand, the term "heartache" itself is a metaphor, personifying the heart as something that can feel pain. This metaphorical language reflects the very real physical sensations that accompany the emotional pain of heartache. These physical symptoms can include muscle tightness, increased heart rate, abnormal stomach activity, shortness of breath, insomnia, loss of appetite, nausea, headaches, and chest pressure.

However, the experience of heartache is not just a matter of figurative language. The neurological processes involved in heartache are very real and have been studied using functional MRI (fMRI) technology. Research has shown that the experience of heartache involves the activation of specific regions of the brain, including the anterior cingulate cortex, the dorsal anterior cingulate cortex, the right-ventral pre-frontal cortex, the secondary somatosensory cortex, and the dorsal posterior insula. These brain regions are associated with processing pain, regulating emotional reactions, and controlling behaviour.

Furthermore, heartache has been found to involve the same brain regions as physical pain. A 2011 study by social psychologist Ethan Kross and colleagues found that the same regions of the brain that become active in response to physical pain are also activated during intense social rejection or loss. This overlap in brain activity suggests that heartache is not merely a metaphor but a very real experience of pain that is processed by the brain in a similar way to physical pain.

Additionally, the physical symptoms of heartache may be explained by the simultaneous triggering of the sympathetic and parasympathetic activation systems in the body. The sympathetic nervous system is the "fight or flight" response, which increases heart rate and prepares the body for action. The parasympathetic system, on the other hand, is the "rest and digest" response, slowing the heart rate and breathing. When both systems are activated at once, it can create a sense of conflict in the body, leading to physical discomfort and possibly chest pains.

In conclusion, while the term "heartache" itself may be a metaphor, the experience it describes is much more than figurative. Heartache involves a complex interplay of emotions and physical sensations that are processed by the brain in a similar way to physical pain. The very real nature of heartache highlights the power of language to express and make sense of our deeply felt human experiences.

What are the physical symptoms of heartache?

Heartache is more than just a metaphor—it is a very real experience of both physical and emotional pain. While the mental foundations that support the connection between sadness and physical pain remain unclear, studies have shown that the two are inextricably connected.

When experiencing heartache, one may feel muscle tightness, increased heart rate, abnormal stomach activity, and shortness of breath. Other physical symptoms of heartache include:

• Pain or discomfort in the chest, back, shoulders, neck, jaw, or arms
• Sweating a lot for no reason
• Feeling unusually tired for no reason
• Nausea, feeling sick to the stomach, and vomiting
• Light-headedness or sudden dizziness
• Rapid or irregular heartbeat

These symptoms can vary from person to person and can be mild or more serious and sudden. They may also come and go over several hours.

What are the emotional symptoms of heartache?

Heartache is a very real emotional pain that can be felt as a dull ache, a piercing sensation, or a crushing sensation in the chest or stomach. It can also manifest as muscle tightness, increased heart rate, abnormal stomach activity, shortness of breath, insomnia, loss of appetite, nausea, headaches, or chest pressure.

Heartbreak is a type of emotional stress or pain that one feels when experiencing great loss or deep longing. It is often associated with unrequited or lost love, and the pain can be intense and debilitating. The emotional symptoms of heartache can include:

• Intense sadness
• Anger
• Confusion
• Yearning for the person who has left
• Lack of emotion control, including inappropriate phoning, writing, or emailing
• Sobbing
• Drinking too much
• Dramatic entrances and exits
• Shame
• Anxiety
• Depression
• Withdrawal from friends, family, and usual activities
• Changes in eating habits
• Reduced motivation
• Lack of energy
• Insomnia
• Sleeping too much
• Loss of appetite
• Overeating
• Nausea
• Indigestion
• Intestinal disorders
• Excessive weight gain or loss
• Headaches
• Shortness of breath
• Chest pressure
• Tightness or heaviness in the throat
• Exhaustion
• Muscle tightness or weakness
• Body pains
• Fidgety restlessness

Heartache is believed to be part of the survival instinct, with the "social-attachment system" using the "pain system" to encourage humans to maintain their close social relationships. Social rejection and loss are processed in the same regions of the brain as physical pain, and the two types of pain are thought to be inextricably connected. The experience of heartache may be due to the simultaneous triggering of the sympathetic and parasympathetic activation systems, which can cause conflicting actions in the heart and create a sensation of physical pain.

How does heartache affect behaviour?

Heartache is an emotion that can be caused by a variety of factors, such as sadness, loss, or unrequited love. The experience of heartache is associated with physical pain and discomfort, and it is not just a metaphor. The sensation of heartache is linked to the activation of specific brain regions and the release of certain hormones, which can have a significant impact on behaviour.

The emotional pain of heartache involves the same brain regions as physical pain, including the anterior cingulate cortex, dorsal posterior insula, and secondary somatosensory cortex. This suggests a strong connection between emotional and physical pain. The anterior cingulate cortex, which regulates emotional reactions, may respond to stressful experiences by increasing the activity of the vagus nerve, resulting in pain and nausea. This overlap in brain activity can be observed through functional MRI (fMRI) studies, where individuals experiencing heartache show similar brain activity to those in physical pain when viewing images of their loved ones.

The behavioural consequences of heartache are influenced by the interplay between the sympathetic and parasympathetic activation systems. The sympathetic nervous system, associated with the "fight-or-flight" response, increases heart rate and prepares muscles for action. On the other hand, the parasympathetic system slows heart rate and breathing, regulating functions like digestion and saliva production. When both systems are activated simultaneously, it can lead to physical discomfort, including chest pains.

Heartache can lead to a range of behavioural changes, including changes in eating habits, reduced motivation, anxiety, and depression. Individuals experiencing heartache may exhibit a lack of emotion control, engaging in behaviours such as excessive contacting of their loved one, sobbing, drinking too much, or making dramatic entrances into their loved one's space. This can be understood as a conflict between the orbital frontal cortex, which controls behaviour, and the midbrain reward system, which remains motivated to obtain the "reward" of the loved one.

Additionally, heartache can be addictive, similar to the effects of drugs like nicotine and cocaine. The experience of love activates the caudate nucleus and increases dopamine, creating a "goal-oriented motivational state." When a relationship ends, the brain continues to crave the "reward" of the loved one, leading to intense cravings and withdrawal symptoms. This can result in behaviours such as pleading for reconciliation or obsessively thinking about the lost relationship.

The physical and emotional pain of heartache is believed to be evolutionarily advantageous, serving as a social alarm system. Social rejection or loss activates the "pain system," encouraging individuals to maintain close social relationships. This response may have been crucial for survival in prehistoric times, when exclusion from the group signalled danger.

In summary, heartache is an emotion that affects behaviour by activating specific brain regions and hormonal responses, resulting in physical discomfort and behavioural changes. The experience of heartache involves a complex interplay between emotional and physical pain processing systems, addiction-like responses, and evolutionary survival mechanisms.
