Why the body's internal signals shape how we cope
Interoception is the everyday business of noticing and making sense of what is happening inside you — a racing heart, a tight stomach, a shallow breath. It is not one skill but several: noticing sensations, interpreting them accurately, and trusting them enough to act on them. These studies treat those strands as separable, and that matters because they can move in different directions with age and with emotional state [1][4].
The link to coping runs through emotion. Bodily signals are part of how an emotional reaction gets its intensity, so how strongly you register them can shape how strongly you feel and remember an event. In one dissertation spanning early to late adulthood, older age was associated with weaker sensitivity to experimentally perturbed bodily signals, and that weaker sensitivity in turn reduced both the emotional response and the memory boost tied to those signals [1]. In other words, the signal itself was quieter, and so was its downstream effect.
Does interoception really decline with age?
Mostly, but not uniformly. A systematic review of 22 studies found age-related declines in interoceptive sensitivity in about 48% of comparisons, no age difference in about 32%, an age-related increase in about 16%, and an inverted U-shape — rising then falling — in about 3% [4]. That spread is the headline: the direction of change depends on which dimension of interoception is measured and which age groups are compared, so "interoception declines with age" is only partly true.
The review also suggests the consequences are not purely negative. Altered mind-body connections in older adults were associated with fewer high-arousal and more positive emotional experiences, with cognitive protective effects, and with better body representation correlating with better interoceptive sensitivity [4]. This is consistent with a mix of decline and compensation rather than a simple downward slope. Note the scope: this review synthesizes comparisons across age groups rather than following the same people over time, so it describes age patterns, not individual trajectories.
If sensitivity fades, can attention bring it back?
There is a promising hint that the decline is not the whole story. In the lifespan dissertation, when older adults were explicitly directed to attend to their bodily signals while learning new material, they showed memory benefits comparable to younger adults [1]. The interpretation offered is that orienting toward interoception can work as a memory strategy at any age, with brain regions involved in self-awareness and emotional processing — the posterior cingulate cortex and amygdala — potentially supporting that benefit [1]. This is a proposed mechanism, not an established one, and it concerns memory rather than coping directly.
Treatment research points in a similar direction for emotion. In a longitudinal panel of 444 adult patients in multicomponent psychotherapy, followed weekly for 4 to 12 weeks, trust in bodily signals was among the factors positively associated with well-being, alongside readiness to confront negative emotions and activity engagement [2]. Noticing bodily sensations, not worrying, and self-regulation contributed indirectly to well-being changes [2]. The authors frame these as hypotheses generated by an exploratory network model, and the sample was adults in treatment rather than a lifespan sample, so this speaks to coping during therapy, not to development across the whole lifespan.
What the evidence can and cannot yet tell us
The pieces do not yet form one continuous lifespan picture. The dissertation compares age groups from early to late adulthood and examines interoception's role in emotional memory [1]; the review aggregates cross-age comparisons [4]; the treatment panel tracks adults over weeks [2]. Each answers a different question, and none follows the same people from young adulthood into old age while measuring both interoceptive accuracy and emotional coping.
Shorter-term work adds texture but narrows the scope further. In women aged 40–55, longitudinal assessments during Tai Chi linked improvements in interoceptive sensitivity to reductions in depressive symptoms [3] — a specific midlife window and a specific practice, not a general lifespan claim. And in a 21-day study of adults with restrictive eating disorders, moment-to-moment swings in interoceptive attention were examined as a risk factor for self-injury, suicidality, and disordered eating [5], pointing to reactivity — how much attention to bodily signals jumps between moments — as a distinct feature worth tracking, separate from average accuracy or sensibility. Taken together, the evidence supports a real connection between interoception and emotional coping, while leaving the exact shape of change across a full lifetime an open question.

Interoceptive awareness and emotional episodic memory across the adult lifespan
Across early to late adulthood, older age was associated with reduced sensitivity to interoceptive perturbations, which in turn lowered the emotional response and memory modulation tied to bodily signals, though directing older adults to attend to interoception produced memory benefits comparable to younger adults.
The associations between interoceptive awareness, emotion regulation, acceptance, and well-being in patients receiving multicomponent treatment: a dynamic panel network model
In a weekly longitudinal panel of 444 adult psychotherapy patients, trust in bodily signals was positively associated with well-being, while noticing bodily sensations, not worrying, and self-regulation contributed indirectly to well-being change.
