Alexithymia: why some people don’t understand their own emotions

Some people don’t just struggle to talk about their feelings – they struggle to know what they feel in the first place.

In daily life, we assume everyone can tell sadness from anger, or stress from excitement. For a sizeable minority, that inner radar is blurred, and the consequences reach far beyond awkward conversations.

What alexithymia actually is

Alexithymia is a psychological trait, not a disease. The word comes from Greek roots meaning “no words for emotion”. The term was coined in the 1970s by psychiatrist Peter Sifneos to describe people who find it unusually hard to recognise and describe their feelings.

Using standard questionnaires such as the Toronto Alexithymia Scale, researchers estimate that roughly 17–23% of the general population show significant levels of alexithymia. That’s not a rare curiosity. It is closer to a quiet, everyday reality that many people live with, often without a name for it.

Alexithymia does not mean “no emotions”. It means struggling to identify, label and put those emotions into words.

Imagine being asked to describe a colour you’ve never seen. You sense something is there, but your vocabulary fails. People with alexithymia often report an experience close to that when they try to talk about what they feel.

The brain behind the blurred feelings

Alexithymia appears linked to differences in how the brain processes bodily sensations and emotions. Neuroimaging studies point to altered activity and connectivity in regions such as the anterior insula and the prefrontal cortex, which help integrate physical states with conscious emotional awareness.

The evidence is still evolving, and findings are not always perfectly aligned, but recent meta-analyses tend to support a neurobiological basis. That matters, because it challenges the idea that people “choose” to be emotionally distant or cold.

Rather than a character flaw, alexithymia looks more like a cognitive style shaped by biology, development and life experience.

Primary and secondary alexithymia

Researchers often distinguish two broad forms:

➡️ Amazon: A giant 7.5‑metre anaconda never seen before is found… during a show with Will Smith

➡️ Goodbye hair dye for grey hair: what you need to add to your conditioner is pure magic

➡️ No plastic or fabric bags: this baker reveals the trick to keep bread fresh for days

➡️ What it means when someone always looks you in the eyes, according to psychology

➡️ The genius hotel trick to clean shower doors streak-free and make them crystal clear again

➡️ After turning down France for the US, Australia could end up with no submarines at all

➡️ One sock is all you need: the grandma-approved trick to clean blinds back to new with no effort

➡️ Not Nivea or Neutrogena: the best moisturising cream brand according to this expert study

• Primary alexithymia – appears as a long-standing personality trait. Genetic, neurobiological and early developmental factors seem to play a key role.
• Secondary alexithymia – emerges after psychological trauma, chronic stress, physical illness or mental health conditions such as depression. Emotional functioning was previously more typical, then changed.

In this second case, alexithymia can operate as an unconscious protective response. By dulling access to painful feelings, the mind tries to shield itself from overwhelming distress. That protection can come at the cost of long-term emotional and relational difficulties.

How alexithymia shows up in everyday life

From the outside, alexithymia can look like emotional flatness. Inside, the picture is different. People usually sense that “something is wrong” but struggle to pin down whether it is sadness, fear, anger or shame.

Instead of naming precise feelings, they might report a vague unease, irritability, or a general sense of being “off”. They may over-rely on practical language and skip the emotional layer entirely.

Typical difficulty	How it can sound in daily speech
Identifying emotions	“I don’t know what I feel, just weird.”
Describing emotions	“Something’s wrong, but I can’t explain it.”
Linking body and feelings	“My chest is tight, but I’m probably just tired.”
Understanding others’ emotions	“I never know why people get so upset.”

These patterns can have a quiet but steady impact on friendships, family life and romantic relationships. Offering emotional support to a partner, for instance, becomes harder when your own inner life feels fuzzy or out of reach.

When feelings turn into physical pain

Another striking feature of alexithymia is how often emotion shows up in the body instead of in words. People might complain of headaches, stomach aches, chest tightness, muscle pain or crushing fatigue without any clear medical explanation.

When emotions aren’t processed mentally, they often surface physically – a phenomenon known as somatisation.

This doesn’t mean symptoms are “all in the head”. The body and brain are tightly linked. Stress hormones, inflammation and nervous system arousal can all produce very real physical discomfort.

Research suggests alexithymia raises vulnerability to conditions such as depression, anxiety and substance misuse, including alcohol dependence. It also tends to correlate with poorer self-rated health and more frequent visits to doctors for unexplained physical complaints.

Cold-hearted, or just wired differently?

A common stereotype paints alexithymic people as unfeeling or lacking warmth. That image doesn’t fit the science. Many care deeply about others but are simply less skilled at reading internal states – both their own and, sometimes, other people’s.

Psychologists often describe alexithymia as having three components:

• Difficulties identifying feelings – noticing something is happening inside but not knowing what.
• Difficulties describing feelings – finding the words and nuance to explain those internal states to others.
• Externally oriented thinking – focusing on facts, tasks and concrete details rather than inner experiences.

This externally oriented style can make someone look pragmatic, efficient or “no-nonsense” in professional settings. In close relationships, though, it may be read as distance or disinterest, which can fuel misunderstandings on both sides.

Can you recover, or just adapt?

Alexithymia is not listed as a disorder in major diagnostic manuals such as the DSM‑5 or the World Health Organization’s ICD‑11. At present, specialists tend to view it as a trait that sits on a continuum in the general population.

For that reason, talk of a cure doesn’t fully match the current understanding. Instead, clinicians speak about learning to live with alexithymia and reducing its impact on mental health and relationships.

People may never turn into poets of emotion, but they can often become more fluent and confident in naming what they feel.

Therapies that may help

Several therapeutic approaches show promise, especially those focused on specific skills rather than purely insight-based work. Examples include:

• Skills-based psychotherapy – techniques from cognitive-behavioural or dialectical behaviour therapy that teach people to notice bodily sensations, thoughts and actions, then link them to emotional labels.
• Group therapy – structured sessions where participants practice recognising emotions in themselves and others, often with feedback in real time.
• Mindfulness-based approaches – exercises that train non-judgemental awareness of internal states, helping individuals map subtle physical cues to emerging feelings.
• Art therapy and music therapy – less verbal forms of expression that give emotions a shape, sound or colour before they gain precise words.

For someone who finds conventional psychotherapy intimidating or frustratingly abstract, these creative or body-focused methods can feel more accessible. They bypass the demand for perfect language and instead work from what is present: tension in the shoulders, a chaotic piano improvisation, a dark sketch on paper.

What alexithymia feels like from the inside

Consider a common scenario. A young adult comes home from work exhausted, with a knot in the stomach and a pounding head. When a partner asks what is wrong, the only answer that comes is: “Nothing, I’m fine, just tired.”

Underneath that phrase may sit a muddle of frustration with a manager, fear about performance, or sadness after a social snub at lunch. The body is loud, the emotions are real, but the person cannot yet sort or name them. Both partners leave the conversation dissatisfied: one feels shut out, the other feels pressured to explain something they barely grasp.

Over time, cycles like this can erode intimacy and feed conflict. Understanding alexithymia gives couples, friends and families a shared framework. The question shifts from “Why don’t you care?” to “How can we build a shared language for what you’re feeling?”

Living with someone who has alexithymia

For partners, parents or close friends, a few practical ideas can make daily life easier:

• Ask about physical sensations first – “Where do you feel this in your body?” – before asking for an emotion word.
• Offer simple choices instead of open questions: “Does it feel more like anger or sadness?”
• Share your own inner states out loud to model the process of naming emotions.
• Give extra time and space for responses, without pushing for instant clarity.
• Encourage professional support if distress, conflict or physical symptoms are mounting.

These tactics do not turn anyone into an emotional mind-reader, but they can soften misunderstandings and reduce pressure on the person who struggles to articulate their inner life.

Key terms that often get mixed up

Alexithymia sits alongside several other concepts that sometimes cause confusion:

• Emotional intelligence – a wider set of skills, including understanding others’ emotions, managing feelings and using them in decision-making. Someone can have low emotional intelligence without meeting criteria for alexithymia, and vice versa.
• Hypersensitivity – a pattern of intense reactions to stimuli or social situations. Some people are both highly sensitive and alexithymic: they feel a lot, but cannot easily sort or label what they feel.
• Autism – autistic people have higher rates of alexithymia on average, but the two are not the same thing. You can be autistic without alexithymia and alexithymic without autism.

Being clear about these distinctions helps avoid quick judgements and sloppy labels. For individuals already struggling to make sense of their inner experience, that precision can itself feel like a form of respect.
