Imagine feeling your heart race or your stomach tighten and having no clear idea whether you’re excited, anxious or upset.
For millions of people around the world, that uncertainty is a regular part of life. The experience is known as alexithymia, a trait that affects how people recognize, interpret and describe their emotions.
Although the term may sound unfamiliar, researchers estimate that between 5 and 10 percent of the general population may experience alexithymia to some degree. Rather than preventing someone from feeling emotions, the condition makes it difficult to understand exactly what those emotions are and how to communicate them.
The word itself comes from ancient Greek and translates roughly to no words for emotions. It was introduced by psychotherapists in the 1970s to describe a pattern of emotional difficulties that has since become the focus of growing scientific interest.
Difficulty identifying emotions
One of the most common signs of alexithymia is struggling to determine what an emotion actually is.
A person may notice physical sensations such as a pounding heart, sweaty palms or a knot in the stomach without understanding the emotional cause behind them. Fear, excitement, anger and anxiety can all feel surprisingly similar, making it difficult to tell one from another.
Instead of recognizing emotions directly, many people with alexithymia experience only the physical side of those feelings.
Trouble putting feelings into words
People with alexithymia often find it challenging to explain their emotions to others.
They may know something feels wrong or uncomfortable but have trouble describing why. Conversations about feelings can become frustrating because emotional experiences are difficult to label or articulate.
This does not mean someone lacks empathy or emotional depth. In many cases, the feelings are present and intense. The challenge lies in identifying and expressing them.
A focus on facts over feelings
Psychologists have observed that many people with alexithymia tend to focus more on external details than inner emotions.
They may concentrate on what happened during an event, what was said or what actions need to be taken, while paying little attention to how the experience made them feel.
This thinking style, known as externally oriented thinking, can make emotional reflection feel unfamiliar or uncomfortable.
Challenges in relationships
Emotions play a major role in how people connect with one another.
When someone struggles to identify or communicate their feelings, relationships can become more complicated. Friends, family members or romantic partners may interpret emotional reserve as distance or indifference, even when the person cares deeply.
Research has linked alexithymia to difficulties with emotional intimacy and relationship satisfaction. Someone may know they are upset with a loved one but be unable to explain the reason behind those feelings.
Difficulty regulating emotions
People with alexithymia may also have trouble managing emotions once they arise.
Studies have connected the trait to behaviors such as emotional suppression, avoidance and social withdrawal. Because emotions are difficult to identify, finding healthy ways to cope with them can become more challenging.
Over time, these patterns may affect communication, self awareness and overall well being.
Differences in decision making
Emotions help people evaluate situations and make choices, especially when there is no clear right or wrong answer.
Researchers have found that alexithymia can influence decision making because emotional signals are harder to interpret. A person may struggle to determine whether they are feeling caution, excitement or intuition when facing an important choice.
Without those internal cues, weighing risks and uncertainties may become more difficult.
Connections to other health conditions
Alexithymia is not classified as a mental health disorder on its own. However, it appears more frequently among people with several neurological, psychiatric and medical conditions.
One of the strongest associations is with Autism spectrum disorder, with studies estimating that about half of autistic people may also experience alexithymia.
Researchers have also found links with Post-traumatic stress disorder, Obsessive compulsive disorder, Schizophrenia, anxiety, depression and certain chronic illnesses, including cancer.
Not everyone with these conditions has alexithymia, and many people with alexithymia have none of them. Still, scientists continue to study whether difficulties understanding emotions contribute to challenges across these diverse conditions.
Can alexithymia improve?
Experts say alexithymia does not have to be permanent.
Approaches such as therapy, mindfulness practices, meditation and exercises designed to improve emotional literacy may help people become more aware of their feelings and bodily sensations.
Learning to recognize emotional signals can take time, but many specialists believe it is a skill that can be developed.
For people living with alexithymia, understanding why emotions can feel confusing is often the first step. What once seemed like an unexplained racing heart or a persistent knot in the stomach may gradually become easier to interpret, opening the door to deeper self-awareness and stronger connections with others.
