Why Old Emotional Pain Keeps Returning – and What Science Says Helps

.

The Idea of "Two Levels of Pain"

Author and spiritual teacher Eckhart Tolle has described suffering as having two layers: the pain we create in the present, and old pain that lingers in mind and body. The idea resonates with many people. They notice the same conflicts, the same kinds of partners or the same self-doubt returning again and again.

Psychology does not offer one neat explanation for this. But research on how we handle emotions gives some useful clues.

Why Pushing Feelings Away Backfires

Most of us have learned to hide unpleasant feelings. Scientists call this "suppression" (keeping an emotion from showing). It looks efficient, but it has a price.

In experiments by Stanford psychologist James Gross and colleagues, suppressing emotions produced clear effects in both negative and positive emotional films, including increased sympathetic activation of the cardiovascular system (the body's stress response). Other work found that suppression is a cognitively demanding form of self-regulation and can impair memory for what happens during that time.

The effects also show up in daily life. In a series of studies, people who habitually suppress their feelings report less positive emotion, more negative emotion and worse interpersonal functioning than people who use "reappraisal" (looking at a situation from a new angle).

In plain terms: hiding feelings does not make them disappear. It can leave us more tense and more distant from other people.

Putting Feelings Into Words

One of the best-studied alternatives is surprisingly simple: give the feeling a name.

In a 2007 brain-imaging study at the University of California, Los Angeles (UCLA), thirty people viewed images of individuals making different emotional expressions while researchers scanned their brains. The result: labeling feelings seemed to activate a region in the prefrontal cortex, which in turn may dampen the amygdala, the brain's alarm center.

Lead researcher Matthew Lieberman compared it to a driver reacting to a traffic light: putting feelings into words seems to "hit the brakes" on emotional responses.

Important limits apply. The study measured reactions to pictures of faces, not deep personal trauma. It shows a plausible mechanism, not a cure for long-term pain.

Does Writing About Pain Help?

Many therapists suggest writing about difficult experiences. The scientific picture is mixed.

A large analysis of 146 randomized studies of this method, led by psychologist Joanne Frattaroli, found a small overall benefit. Another review focusing on people with physical or psychiatric conditions found a similarly modest effect: expressive writing significantly improved health, with an effect size of 0.19.

Not every analysis agrees. A 2009 review of 30 randomized trials found no significant overall long-term effect when it pooled outcomes measured at least four weeks later.

The fair conclusion: writing may help some people, but it is not a guaranteed fix.

What About "Pain Stored in the Body"?

A popular claim says old emotions are literally stored in the body and must be "released." Poetic as it sounds, this is not something the studies above prove.

What research does support is narrower. Avoiding feelings has measurable effects on the body's stress response, and attention to emotions can calm the brain's reaction. Whether memories are physically stored in tissue is a different question, and scientific evidence for it remains limited.

Practical Steps to Try

None of these replace professional care, but they are low-risk starting points:

• Name it. When a strong feeling appears, try a simple sentence such as "I feel anxious" or "I feel rejected." Be as precise as you can.
• Write it down. A few short journaling sessions about a stressful experience may help some people. Stop if it feels overwhelming.
• Notice the pattern. Ask yourself where a reaction feels familiar from earlier in life. Seeing a repeating cycle is the first step to changing it.
• Talk to someone. Sharing with a trusted friend or therapist is a classic form of putting feelings into words.

When to Seek Professional Help

Deep wounds from abuse, neglect or other trauma should not be handled alone. A licensed psychologist or psychotherapist can offer structured, evidence-based support.

If you are thinking about harming yourself, contact emergency services right away. In the United States, you can call or text 988 (Suicide & Crisis Lifeline). Elsewhere, please contact your local emergency number or crisis service.

Outlook

Old pain tends to repeat when it stays unspoken. The research is clear that avoiding feelings has costs, and promising, though not perfect, that naming and processing them can ease their grip. Small, steady steps matter more than dramatic breakthroughs.
