Trust Your Gut: Harnessing the Power of Interoception

Updated: Aug 17, 2020

When we ask others, “How do you feel?” we’re inquiring about emotions and physical sensations. This is just one of many common sayings reflecting folk wisdom about the mind-body connection. Researchers are delving deep into the science and physiology of this brain, and body wisdom called interoception.

Interoception is simply our “perception of the state of the body.” 1 Not to be confused with introspection - the inward reflection on one’s thoughts and feelings - interoception deals with our physical body, sensations, and perceptions. It’s also different from our ability to sense the external world around us (exteroception) and our sense of different parts of our bodies relative to each other and moving through space (proprioception). Interoception instead allows us to “sense physiological signals originating inside the body, such as hunger, pain, and heart rate.” 3

Neuroscientists and psychologists have long studied the abilities we have to sense our own internal bodily experiences. Interoception provides essential feedback allowing our central nervous system to keep our bodies in a tightly controlled homeostatic balance. Our brains keep track of and make adjustments to keep our bodily processes running smoothly, from maintaining a constant body temperature to regulating breathing rate, heart rate, hunger, and thirst. We typically think of these processes as subconscious phenomena, but new science shows that your gut feelings are interoceptive sensations that can sometimes act as useful behavioral guides. It’s also another way to build neuroplasticity.

Going with Your Gut

In financial markets, gut feelings are often discussed. New research suggests that our autonomic systems' feedback to our brain can beneficially influence complex decision making. Interoceptive abilities can happen in the gut, but can also result from a sense of the heart, lungs, or other aspects of the body. A recent study investigated the interoceptive abilities of traders making rapid, high-stakes decisions on the markets. The results are shocking: traders who were better at introspection than the general population did better at trading! The more accurately they were able to estimate their heart rate, the more profitable they were.

This study of high-risk decision making on the trading floor is among the first real-world studies linking interoceptive ability to performance. The results sync with previous research showing that people in a laboratory setting could make more rapid and optimal gambling decisions with interoception without spending time using conscious reasoning. These studies don’t “prove” that being in touch with your heart rate yields better performance, but they present strong evidence that an ability to listen to one’s gut does ead to better decision making.

Another recent study tested experience-based risk-taking behavior by virtually inflating a body silhouette, where more pumps into the silhouette yielded bigger prizes. Participants had to learn when to stop inflating and avoid popping the items, which would result in losing the prize. The results showed that higher interoceptive skills led to more conservative decision making of the body stimulus, suggesting that people with higher body awareness themselves were more careful making decisions about the body. 7

There is a strong connection between internal self-awareness and bodily awareness because they have been linked to interoceptive processing of body-related stimuli. It turns out that people with high interoceptive abilities showed a stronger memory-guidance of spatial attention towards images of the body compared to pictures of familiar objects.7 We gather from this data that more accurate interoception means stronger internal somatic awareness which helps guide our intuition to make better decisions!

Decision making is also influenced by emotion-regulation capacity. Mental clarity is the result of proper emotion-regulation, which can be strengthened by using interoception techniques. A recent study found that early life adversity, specifically childhood trauma, negatively impacts interoception accuracy. Interoceptive accuracy is strongly related to emotion-regulation, where higher interoceptive efficiency was associated with bodily and emotional awareness. Participants with childhood trauma had lower interoceptive awareness after stressful events, suggesting an inefficient mind-body connection. 5 Mastering interoception seems to be crucial for people who have been exposed to early life adversity, trauma, and related anxieties because somatic awareness can facilitate the brain-body connection and help with self-awareness and healing.

The Physiology of Interoception

Where do neuroanatomists think interoception lives in our brains?

Our brains work as dynamic, ever-shifting networks and pathways that do not easily map to the colored blobs that show up on brain scans. The interoceptive channels seem to “represent the ongoing status of all tissues and organs of the body, including skin, muscle, and viscera.”2 Sensory neurons that ascend from the body to the brain tell our central nervous system about the condition of the body, triggering signaling cascades that act to correct any perturbations from the delicate homeostatic balance. We experience automatic feelings related to homeostatic balance regularly - we feel hot or cold, feel pain, itch, feel hunger or thirst, muscle aches, or a need to breathe more deeply.2

Our internal somatic awareness and our feelings are deeply intertwined: the parts of the brain that make us consciously aware of our emotions depend on how our brains represent our physical state.2 A brain region called the insula is known to play an essential role in processing both our emotional awareness and physical body. The multitude of signals given off about our bodies’ state all come up into the insula for processing. The body-emotion link is strong here: we sometimes act on emotions that aren’t linked to subjective feelings - these are perhaps generated by a subtle internal awareness of our inner physical state.

Neuroscientists are interested in how the brain forms these higher-order representations of our physical bodies. While our brains control many homeostatic processes consistently below the conscious awareness level, the central nervous system also creates a subjective, higher-order perception of the body’s state. While our sense of the body might be elicited by an automatic change to maintain homeostasis, we can also become aware of our bodies at other times. Interoception, in this sense, happens “from the point in processing onward where there is a higher-order integration of information, sensory and neural, taking place to form a body state representation in the central nervous system.”2 Some brain injury studies point to the importance of interoceptive signals for learning. People with brain damage in a specific area called the ventromedial prefrontal cortex can lose the ability to learn from negative feedback despite retaining IQ.3

A recent functional connectivity MRI study revealed that interoception and anxiety states have some overlapping biomarkers. The intensity of interoception is mainly governed by top‐down processing of somatic information, while anxiety is mostly related to bottom‐up processing in interoceptive attention tasks. The findings point to the heavy involvement of the cingulo-opercular task control (COTC) network, which transmits interoception to the superior cortex for cognitive control and guides intrinsic arousal involved in attention sustainability. Two other significant systems were identified biomarkers for interoception: sensorimotor area (SSM), which is extensively connected to the insula, and the ventral attention network (VAN), which plays a role in attentional trend and processing emotional signals of anxiety.8 COTC plays a role in anxiety and interoception, but the connectivity within this network may be abnormal for anxiety-related sensations compared to interoception. The overlaps in functional connectivity between anxiety and interoception help us understand that interoception may be an excellent skill to work with in anxiety treatment.

Healing Powers

Interoception has long been recognized for its healing potential in healing the body and mind. Enhancing interoceptive abilities may be a way to address mental and physical health problems and increase neuroplasticity.

Some traditional Mexican healing and addiction treatment ceremonies employ salvia, a substance known to alter our interoceptive perceptions. Salvia leaves contain salvinorin-A, a potent naturally occurring psychedelic substance.4 Scientists know that “salvia alters dopamine levels in ancient parts of the brain responsible for motivation, reward, and the internal sense of what is going on in our bodies.”4 Low doses of salvinorin-A can improve interoceptive abilities, and subjects experienced their bodies as "safe and trustworthy, suggesting that increasing interoception can be helpful in healing addictions.

The healing powers of yoga are increasingly well known and although practices vary tremendously, each yoga practice’s core teaching is body awareness and enhancing the body-mind connection. The fundamentals of all yoga poses and exercises rely on interoception. A recent study has shown that an 8-week yoga intervention helped reduce symptoms of depression, anxiety, stress, and increased interoceptive abilities in patients who have PTSD.6 Perhaps the substantial benefits of yoga stem from its focus upon improving interoceptive skills. Yoga’s origins are in meditative practice aimed at concentrating on the body-mind connection, with each pose(asana) enhancing a slightly different area of bodily awareness.

Some Western researchers suggest that interoception could have additional clinical applications in the treatment of emotional problems or the many medical conditions that respond to psychological factors. For example, it’s long been understood that emotion plays a major role in the experience of pain. Negative emotions are known to intensify experiences of pain and lower our pain tolerance abilities, while positive emotions have the opposite effect. Interoception and the body-emotion link are therefore essential for understanding the causes and treatment of chronic pain.1

In Western psychology, interoceptive exposure techniques help expose people to uncomfortable bodily sensations. Interoceptive conditioning is sometimes used to treat a panic disorder by including the physical sensations associated with panic attacks in a controlled environment while working to reduce a patient’s conditioned fear that the appearance of these symptoms will inevitably mean a panic is on the way. Interoceptive conditioning has also been investigated in the treatment of cancer-related fatigue, hypertension, eating disorders, mood and anxiety disorders, and drug addiction. Interoception has also been explored in relation to emotional regulation, decision making, sexual dysfunction, empathy, hypnosis, and meditation.1 Most people in medicine and healthcare are trained to be very cognitively oriented and forget about reading the subtle information from their bodies or guiding their patients to sense themselves from their inner sensations and perceptions. Interoception is a useful tool to lay strong foundations for a genuine body-mind connection.

Why is it so important to develop this skill? Interoceptive abilities form the very underpinnings of the powerful mind-body connection. In psychosomatic illness, interactions between perturbations in our homeostatic balance and emotional states are very likely at play. The “feeling self” is not just in the head - it is rooted throughout the entire body.2 When we can balance the inner experience of our bodies with our outer experience of the world, then true peace and harmony can occur.

Body Scan Meditation

While the applied science of interoception is still a fledgling field, there are some proven ways to get back in touch with your body.

If you prefer to listen to an audio guide, a recorded body scan meditation is available from the University of Berkeley’s Greater Good In Action.

This body-scan meditation asks you to focus on different areas of your body, one by one. Moving from your toes to the top of your head, the exercise helps you become mindful of the body. Although we often do not notice, our bodies respond to our emotions. If you pay attention, you are likely to find strong sensations in different parts of the body. These feelings may be caused by stress, such as a tightness in the stomach or shoulders. Doing a systematic body scan helps you relieve tension where you find it. As you go through the body scan, remember not to judge uncomfortable feelings when and where you find them. Simply notice the tension - a tightness in the forehead, a clenched jaw, and let go with the breath. Remember that you may have to repeat the 'letting go' part multiple times. If you experience mind wandering or have a hard time keeping a sharp focus on each layer of the body throughout the body scan, take a few cleansing breaths or start to count your breaths for a few rounds to regain focus. Always remember to be non-judgemental and accepting of yourself and your current emotional state. Simply observe what is happening. With awareness and acceptance, the ‘letting go’ becomes easier.

Begin in an upright seated position or lying down on the floor. Create a straight line with your upper body from head to pelvis. Let your shoulders down away from your ears, bring your chest forward, and draw your belly in. If you are sitting up, straighten your spine, lifting yourself from the crown of your head. If you are lying down, draw your chin closer to your chest. Find a relaxed state in the position you are in. If you feel tension by being in this position adjust to ensure comfort while maintaining an optimally straight spine.

Close your eyes. Now, bring your attention to your body.

Feel the weight of your body on the chair or the floor.

Notice your breath. Follow the natural flow of your inhales and exhales. Notice the breath entering the body and leaving the body.

Bring your attention to your feet. Notice the weight of your feet on the floor. Feel inside your feet - the vibration, pulsations, pressure. With the out-breath, relax your feet.

Notice your legs. Feel any tension. Scan the calves, the knees, the thighs, and hips. With the inhale, send attention to any tense areas, on the out-breath, release.

Notice your back. Feel any sore spots and points of tension. With the in-breath, send oxygen to the tension, with the out-breath, release.

Notice your stomach. Feel the sensation of the in-breath in your stomach. On the out-breath, let the stomach soften.

Bring attention to your hands. Feel into the fingertips. Notice any sensations, tingling, pulsing. Feel the aliveness of your hands. With the out-breath, relax your hands.

Notice your arms. Feel sensations in the wrists, lower arm, elbows, upper arms. Let your arms be soft.

Feel your shoulders. Notice any tenseness. Let the shoulders relax away from your ears. Spend a few breaths, in and out, in and out, relaxing the shoulders.

Notice your neck. Notice your throat. Is your throat tight? Breath into the throat. With the out-breath, soften.

Bring your attention to your jaw and to your tongue. Relax.

Bring your attention to your whole head. With the breath, relax the top of your head. With the next breath, relax the forehead.


Allow your attention to expand. Be aware of your whole body. Tune into your breath and send waves of relaxation throughout the body.

Open your eyes when you feel ready.

Notice changes that occurred in your body and your mind. Regular practice of a body scan meditation may help you build your interoceptive abilities, becoming more in touch with your body throughout your day. Interoception builds the mindful awareness of bodily sensations and their shifts. For example, after regular mindfulness practice, you might be more likely to notice the sensation of anger rising in your body. You can then use mindful breathing in combination with the body scan to identify anger and self-soothe Do that you can direct anger in a positive direction, making you feel more empowered. Interoception builds mind-body awareness and builds neuroplasticity. It helps you to become more emotionally intelligent and physically aware so that you can make good choices about your own healing and readjust choices based on feedback from your wise body.
