If I asked you right now: are you hungry? Cold? Does your heart feel like it’s beating quickly? How do you know? The answer is interoception — the sensory system that detects signals from inside your body. It is sometimes called the eighth sense, and it is one of the most important yet least-known sensory systems in human development.

Interoception tells us how our body feels from the inside. It registers hunger, thirst, temperature, pain, heart rate, the need for the bathroom, nausea, and the physical sensations that accompany emotions — the tight chest of anxiety, the heavy warmth of calm, the fizzing energy of excitement.

Without interoception, we cannot reliably understand what our body needs or what we are feeling emotionally. For many children — particularly those with sensory processing difficulties, autism, ADHD, or trauma histories — interoceptive processing is disrupted.

Interoception and Emotional Regulation

The link between interoception and emotional regulation is profound. Emotions have two components: a cognitive label (“I feel anxious”) and a physical sensation in the body (tight chest, shallow breathing, racing heart). Interoception is the system that detects those physical sensations.

A child with poor interoceptive awareness may not feel the early physical signs of rising anxiety, hunger, or fatigue. By the time they register that something is wrong, they are already in meltdown or shutdown. Teaching interoception is teaching emotional awareness from the inside out.

Signs of Interoceptive Difficulties in Children

Interoceptive difficulties are more common than most people realise. Here are some signs to watch for.

Under-Responsiveness to Body Signals

• Does not notice when they are hungry or thirsty — may go all day without eating or drinking unless prompted
• Does not notice when they need to use the bathroom until it is urgent — or has accidents despite being toilet trained
• Seems unaware of pain — does not notice minor injuries, or does not seek comfort after hurting themselves
• Cannot identify where in their body they feel emotions
• Difficulty knowing when they are tired
• Gets sick without seeming to notice early symptoms

Over-Responsiveness to Body Signals

• Hypervigilant about body sensations — catastrophises minor physical sensations
• Intense anxiety about internal body feelings (heart beating quickly, stomach churning)
• Frequent complaints of stomach aches, headaches, or feeling unwell that do not have a medical cause
• Difficulty distinguishing between emotions and physical illness

Why Interoception Is Particularly Important in Autism

Research shows that many autistic individuals have significant interoceptive differences. This helps explain several aspects of autism that are often misunderstood. Difficulty identifying emotions (alexithymia), meltdowns that seem to come from nowhere, not noticing hunger or thirst, and challenges with toilet training can all be linked to interoceptive processing differences rather than behavioural choice or non-compliance.

Understanding this changes how we approach support. Instead of focusing only on behaviour, we help children develop awareness of their internal landscape — the signals their body sends before a meltdown happens.

Activities to Build Interoceptive Awareness

Building interoceptive awareness is a gentle, gradual process. It involves directing attention to body sensations in a curious, non-judgmental way.

Body Scan Activities

Ask your child to lie down comfortably and take three slow breaths. Then guide their attention through their body: “What does your tummy feel like right now? Does it feel full or empty? Does it feel comfortable or a bit uncomfortable?” Start with simple, concrete sensations before moving to more complex emotional ones.

Before and After Movement

Physical activity creates clear, detectable body signals. Ask your child to notice their heart rate, breathing, and muscle sensations before and after exercise. “Put your hand on your heart. Can you feel it beating? Is it beating fast or slow?” This gives them vocabulary and body awareness simultaneously.

Hunger and Fullness Scales

Create a simple visual scale from 1 (very hungry) to 5 (very full) and ask your child to rate their hunger before and after meals. Start with the extremes — very hungry, very full — and gradually introduce the middle states. This builds the skill of internal monitoring in a concrete, accessible way.

Emotion-Body Mapping

When your child is feeling a clear emotion — joy, frustration, excitement — invite them to describe where they feel it in their body. “When you feel excited, where do you notice it? In your tummy? Your chest? Your legs?” Over time, children build a body map of their emotional states.

Scheduled Check-Ins

Build brief body check-ins into the daily routine. At mealtimes, bedtime, and after school — ask three simple questions: “How hungry are you? How tired are you? How are you feeling?” Consistency builds the habit of internal monitoring.

How Occupational Therapy Addresses Interoception

Interoception is an area I address regularly in my practice in Malta, particularly with children on the autism spectrum, those with ADHD, and children who experience significant emotional regulation difficulties. OT sessions use structured, playful activities to help children tune in to their bodies in a safe and supported environment.

Families are always central to this work. When parents understand interoception and use consistent language and check-in routines at home, the progress is far greater than anything I can achieve in the therapy room alone.
