Why heartbreak can feel like physical pain: What happens in the brain

By Ahmet Taş | Wise News Press

ISTANBUL, TÜRKİYE — Romantic heartbreak is more than sadness: an unwanted breakup can engage brain systems involved in pain, threat and attachment, while thoughts and habits after the split can shape recovery.

Clinical Psychologist Şule Ataş of Üsküdar University NPİSTANBUL Hospital described heartbreak as a psychological and biological response to significant loss. She said the aim after a breakup should not be to erase pain immediately, but to understand the experience, maintain daily functioning and gradually adapt to a changed life.

Why heartbreak can feel physical

A romantic partner can become closely connected to a person’s routines, sense of security, identity and expectations for the future. When the relationship ends, the loss may affect emotional regulation as well as the body. Some people experience stomach discomfort, disrupted sleep, appetite changes, restlessness, tightness in the throat or the sensation that they are physically hurting.

A widely cited 2011 brain-imaging study examined people who had experienced an unwanted romantic breakup during the previous six months. When participants viewed photographs of their former partners and concentrated on the experience of rejection, researchers recorded activity in brain areas also involved in processing the sensory aspects of physical pain.

That finding does not mean heartbreak and bodily injury are identical. A later study using more detailed brain-pattern analysis found that physical pain and social rejection have distinguishable neural representations, despite activity appearing in some of the same broader brain regions. The most accurate conclusion is that emotional and physical pain partly overlap while remaining different experiences.

Thoughts can intensify breakup distress

Ataş said the breakup itself is not the only factor determining how intensely someone suffers. Repetitive thoughts such as “I will never be happy again,” “nobody will love me like this” or “my life has lost its meaning” can transform a period of uncertainty into what feels like a permanent and hopeless future.

Research published in 2025 found that rumination and less adaptive coping strategies were associated with greater disruption following romantic breakups among adolescents and young adults. Repeatedly replaying conversations, searching for one definitive explanation or imagining alternative outcomes may keep attention fixed on the loss rather than helping the mind adjust.

A balanced assessment does not require denying the relationship’s positive moments. It means remembering both its supportive and difficult aspects, recognising unmet needs and considering what the experience reveals about personal boundaries, attachment patterns and expectations from future relationships.

Thinking realistically can also prevent the past from becoming idealised. After a breakup, people may focus heavily on happy memories while minimising conflict, incompatibility or emotional strain. Seeing the whole relationship can make acceptance easier than treating its ending as the loss of a flawless future.

A breakup can trigger a genuine grief process

The end of a relationship may involve more than losing contact with one person. Shared routines, mutual friendships, living arrangements, financial plans and an imagined future may all change at once.

Sadness, longing, anger, crying and temporary confusion can therefore form part of a normal response to loss. Public-health guidance recognises the end of a relationship as one of the experiences that can cause grief, with reactions varying considerably from person to person.

Grief does not follow a fixed timetable or progress in a straight line. Someone may feel better for several days before becoming upset by a song, place, anniversary or unexpected reminder. Recovery is better measured through gradual changes in emotional intensity and daily functioning than by the complete disappearance of sadness.

Ataş advised people not to suppress every difficult feeling or allow life to stop entirely. Maintaining basic sleep and meal routines, continuing essential work or study, staying connected to trusted people and gradually returning to meaningful activities can support adjustment.

“The goal is not to eliminate the pain quickly, but to understand the experience and learn to face the emotions in a healthy way.”

The purpose is not to perform happiness or pretend the relationship did not matter. It is to prevent the loss from becoming the only force organising daily life.

Why monitoring an ex online may delay recovery

Checking a former partner’s social media account can feel like a way to reduce uncertainty, relieve longing or search for evidence that the relationship might restart. Any relief, however, is often brief and may lead to another round of checking.

A 2012 study involving 464 participants found that Facebook surveillance of former partners was associated with greater breakup distress, stronger negative feelings and longing, and lower personal growth.

A newer series of studies published in 2025 similarly linked active observation of former partners on services including Facebook, Instagram and Snapchat with heightened breakup distress. Some effects remained visible months later, particularly among people with higher attachment anxiety.

These findings identify associations rather than proving that every profile visit directly causes emotional harm. People who are already experiencing intense distress may also be more likely to monitor an ex. Nevertheless, reducing digital exposure may help interrupt a cycle in which every new photograph, comment or status update renews hope, jealousy or rejection.

Muting, unfollowing or temporarily hiding an account can create emotional distance without requiring a dramatic public gesture. Where contact remains necessary because of children, work, finances or legal responsibilities, communication can be kept clear, limited and focused on practical matters.

Temporary escape can create longer-term problems

Some people respond to the emptiness of a breakup with increased alcohol use, overeating, uncontrolled shopping, gambling, risky sexual behaviour or the constant pursuit of another relationship.

Ataş emphasised that these reactions are not inevitable. The risk varies according to the person’s previous coping habits, the support available to them and the severity of the emotional burden.

Such behaviours may temporarily numb difficult feelings but do not resolve the underlying loss. They can also create financial, physical or psychological consequences and make the same response more likely whenever distress returns.

Healthier strategies may include naming emotions, talking to a trusted person, exercising, creating structure for previously shared time and writing about the experience without repeatedly analysing every detail.

New research involving young people who had experienced romantic breakups also found that problem-focused and socially supported coping were associated with more constructive adjustment, while rumination and avoidant coping were linked to greater negative effects on daily life.

Recovery therefore involves learning to tolerate and regulate emotions safely, rather than forcing them to disappear or replacing one source of emotional dependence immediately with another.

When professional support may be needed

There is no universal deadline for recovering from a breakup. The length and intensity of distress can depend on the relationship, the circumstances of the separation, previous mental health, attachment patterns and the person’s support network.

Professional support may be useful when sleep or appetite problems, hopelessness, panic, substance use or an inability to complete normal activities continue or become more severe.

The US National Institute of Mental Health advises seeking professional help when severe or distressing symptoms last for two weeks or longer, particularly when they include difficulty sleeping, appetite changes, loss of interest, concentration problems or an inability to complete usual tasks.

Thoughts of self-harm or suicide require urgent attention through local emergency or crisis services. Such thoughts should not be dismissed as a routine or harmless part of a breakup.

Ataş said the most constructive outcome is not simply forgetting a former partner. By examining personal needs, boundaries and repeating patterns without becoming trapped in blame or rumination, someone may develop greater emotional resilience and form healthier relationships in the future.
