Your Body Knows: The Preventive Power of Listening
Our bodies are communicating with us all the time.
It may begin as the heaviness behind your eyes late in the afternoon, a tightening in your shoulders during a difficult conversation, or the unmistakable feeling that you’ve waited too long to eat. It might arrive as a flutter in your stomach before you walk into a room, a sudden desire to step outside and breathe, or the realization that even though you’ve slept for seven hours, you still feel deeply tired.
The question is whether we’re listening, I mean truly listening.
We live in a culture that often encourages us to override these messages. We drink another cup of coffee when we’re tired. We postpone lunch because there’s one more email to answer. We eat quickly while working and barely notice when we become full. We stay up later than we intended because there’s still something to finish, watch, read, or scroll through. We tell ourselves we can rest when the work is done, even though the work rarely seems to be completely done.
Over time, overriding the body's signals can become so familiar that we may stop noticing that we’re doing it.
So I’ve been thinking about a simple idea: the best prevention may begin with listening.
Of course, preventive health certainly includes screenings, medical care, vaccinations when appropriate, movement, nourishing food, sleep, and other evidence-based practices. And listening to our bodies isn’t a substitute for professional medical care, nor can every illness be prevented through lifestyle choices. But learning to notice what’s happening inside us can become another valuable part of prevention. When we become more attentive to changes in energy, appetite, digestion, sleep, tension, pain, mood, breathing, thirst, and our need for rest, we have more information with which to care for ourselves.
The body doesn’t always speak loudly at first. Sometimes it whispers.
The Sense We Rarely Talk About
Most of us learned about five senses when we were children: sight, hearing, smell, taste, and touch. Yet our bodies have other sensory systems as well, including one called interoception.
Interoception is our ability to sense and interpret signals coming from within the body. These signals help the brain keep track of our internal physiological state: hunger and fullness, thirst, heartbeat, breathing, body temperature, fatigue, bladder fullness, nausea, tension, pain, and other sensations arising from inside us.
In simple terms, interoception helps answer the question: What’s happening inside me right now?
This process is happening constantly, whether we’re consciously aware of it or not. Receptors throughout the body send information through the nervous system to the brain. The brain receives and integrates these signals with information about our environment, emotions, memories, expectations, and previous experiences. From all of this information, we develop a sense of how we’re feeling and, ideally, what we might need.
Think about hunger. Hunger isn’t simply a thought that says, It’s noon, so I need lunch. Your body is continually regulating energy availability and communicating with the brain through multiple hormonal, metabolic, gastrointestinal, and neural pathways. We experience the result as sensations that might include an empty feeling in the stomach, reduced energy, irritability, difficulty concentrating, or a growing awareness that food would feel good.
Fullness has signals too. So does thirst. So does fatigue. Even our heartbeat can become part of our conscious awareness. Perhaps you have noticed your heart beating faster before speaking in front of a group, or felt your breathing become shallow during a stressful moment. Your body may register what is happening before you have found words to describe your emotional experience.
Interoception is therefore closely connected to emotional awareness as well as physical awareness. A tightening chest, warm face, unsettled stomach, clenched jaw, or quickened heartbeat may accompany fear, excitement, anger, anxiety, anticipation, or joy. The physical sensation does not always tell us exactly what an emotion means, but it gives us information. And information can help us make choices.
Listening Is a Practice
Some of us are naturally more aware of internal sensations than others, and our ability to interpret those sensations accurately can vary. Stress, trauma, illness, medications, neurodivergence, hormonal changes, chronic dieting, sleep deprivation, and other factors can affect how internal signals are perceived. Interoception is not a magical diagnostic system, and a sensation does not always have an obvious meaning.
That’s why listening to the body is less about immediately interpreting every sensation and more about becoming curious.
Instead of asking, What is wrong with me? we might begin with: What am I noticing?
Perhaps you notice that you consistently become exhausted around three in the afternoon. Before automatically reaching for caffeine, you might become curious about what happened earlier in the day. Did you sleep well? Have you eaten enough? Have you had any water? Have you been sitting in front of a screen for four uninterrupted hours? Have you been concentrating intensely without a break? The answer may be different from one day to another. Listening creates a small space between sensation and response. Inside that space, we have an opportunity to choose.
Knowing When to Eat
Many of us have become accustomed to eating according to external cues. The clock tells us when it is lunchtime. A meeting determines whether we can eat. A diet tells us how much food we are allowed to have. The size of the package or plate tells us what constitutes a serving.
There’s nothing inherently wrong with structure. Regular meal patterns can be very helpful, and some health conditions require eating according to a schedule rather than relying solely on hunger signals. But when it’s appropriate for us, noticing hunger and fullness can add another source of information.
Hunger doesn’t always begin with a growling stomach. You may notice your concentration fading, your energy dropping, or food beginning to occupy your thoughts. When we repeatedly wait until we’re ravenously hungry, it can become much more difficult to eat slowly enough to recognize fullness.
Similarly, fullness isn’t necessarily the moment when we physically cannot eat another bite. There may be an earlier point when hunger has eased, the food is becoming less compelling, and the body begins to feel comfortably satisfied. Listening for that point takes practice. It also requires something many of us do not give ourselves very often: attention while we eat.
This is part of what inspired our Just Eat Challenge—the invitation to experience a meal without simultaneously answering email, watching television, working, scrolling, or accomplishing something else. When we remove some of the competing stimulation, we have a better opportunity to notice taste, texture, satisfaction, hunger, fullness, and how the experience of eating actually feels.
The practice isn’t about eating perfectly. It’s about being present enough to receive information.
Knowing When to Rest
Rest has signals too, although many of us have become exceptionally skilled at negotiating with them.
I will lie down after I finish this. I can push through for another hour. I shouldn't be this tired.
That last sentence is particularly interesting because it replaces a bodily experience with a judgment. You are tired.
The question doesn’t necessarily need to be whether you have earned the right to feel tired. A more useful question might be: What kind of rest is my body asking for? Sometimes the answer is sleep. Sometimes it is movement after sitting for too long. Sometimes it is food, water, quiet, fresh air, solitude, companionship, laughter, or a temporary release from decision-making. There are also times when persistent fatigue deserves medical evaluation. Listening to your body includes recognizing when something feels different from your usual experience and seeking appropriate professional care rather than assuming that every symptom can be addressed through lifestyle changes. Prevention involves attention, but it also involves knowing when attention needs to become action.
Knowing When to Sleep
Our bodies have internal systems that help regulate sleep and wakefulness, including our circadian rhythms and the gradual accumulation of sleep pressure during waking hours. Yet modern life gives us countless opportunities to override these systems.
We may recognize the first signs of sleepiness—yawning, heavy eyelids, decreased concentration—and continue watching television or looking at our phones. Sometimes we push through that first window of sleepiness and later feel strangely awake again. Listening to the body's transition toward sleep can become its own preventive wellness practice.
What would happen if we treated the first signs of genuine sleepiness as useful information rather than an inconvenience? Perhaps the lights become softer. The phone gets put away. The workday is allowed to end. We begin a small evening ritual that tells the nervous system that nothing else is required of us tonight. Not every night will unfold this way. Life includes caregiving, travel, deadlines, insomnia, hormonal changes, illness, and countless other circumstances that affect sleep. I’ve said this before and I believe it’s worth mentioning again. The goal isn’t perfection. The practice is noticing.
Your Body Keeps Notes. You Can Too.
One of the simplest ways to strengthen awareness is to write down what you notice. This doesn’t need to become another elaborate wellness project. You don’t need a special journal or a complicated tracking system. A few sentences can be enough.
You might write:
I felt unusually tired after lunch today.
I slept well after walking outside yesterday.
My shoulders tighten every time I start answering work emails.
I wasn't very hungry at dinner because I ate a satisfying afternoon snack.
I notice that I am more irritable when I go too long without eating.
I feel calmer when I spend even ten minutes outside.
Over days and weeks, patterns may begin to emerge. This is where journaling can become a meaningful preventive practice. A single sensation may not tell us very much. A pattern can tell us more. You might discover that certain foods consistently leave you feeling energized while others don’t agree with you. You might notice that your digestion changes during particularly stressful weeks, that you sleep better on days when you move your body, or that your energy improves when you take a genuine lunch break. A journal can also be useful when you meet with a physician or another healthcare professional because you’re bringing observations rather than trying to reconstruct several months of symptoms from memory.
Intentional Prevention Is an Act of Care
When we hear the word prevention, we may think first about medical screenings, bloodwork, mammograms, colonoscopies, vaccinations, blood pressure checks, or annual physicals. Those forms of preventive care matter enormously. But prevention also lives in ordinary days.
It lives in getting enough sleep consistently rather than waiting until exhaustion forces us to stop. It lives in moving our bodies in ways that support strength, mobility, balance, cardiovascular health, and joy. It lives in eating nourishing food, cultivating meaningful relationships, spending time outside, tending to stress, and seeking medical attention when something changes.
Intentional prevention isn’t a guarantee against illness. We cannot control everything that happens in our bodies, and wellness culture can become harmful when it suggests otherwise. Genetics, environment, access to healthcare, socioeconomic conditions, discrimination, infectious disease, chance, and many other factors influence health.
What intentional preventive practices can give us is greater participation in our own care. They allow us to ask: What is within my reach today?
Perhaps it’s making the appointment you have been postponing. Perhaps it’s going to bed thirty minutes earlier. Perhaps it’s eating lunch away from your computer. Perhaps it’s noticing that the pain you have been dismissing has persisted long enough that you want to talk with your physician.
Healing isn’t always about doing more. Sometimes it begins with noticing sooner.
Try a Daily Body Check-In
For the next week, I invite you to pause once or twice during the day and give yourself a minute of undivided attention. You might close your eyes if that feels comfortable, or simply soften your gaze. Notice your breathing without trying to change it. Notice your jaw, shoulders, chest, belly, hands, and feet. Notice your energy.
Then ask yourself:
Am I hungry?
Am I thirsty?
Am I tired?
Do I need to move?
Do I need to be still?
Is there tension somewhere in my body?
What might feel nourishing right now?
You don’t have to respond to every signal immediately. Sometimes circumstances simply don’t allow it. The first practice is noticing that the signal exists. At the end of the day, write down one thing your body told you. Over time, you may begin to recognize your body's vocabulary.
An Invitation to Listen
This week, choose one part of your day when you normally operate on autopilot. It might be breakfast, your afternoon work period, dinner, your commute home, or the hour before bed. Pause there. Listen. Notice what your body is communicating before deciding what comes next. You may want to keep a small notebook beside your bed, in your bag, or near your workspace and record what you notice for seven days. Don’t try to analyze or fix everything. Simply gather information with curiosity and compassion. At the end of the week, look back over your notes and ask yourself:
What signals does my body send me most often?
Which signals do I tend to listen to?
Which ones do I regularly override?
What is one small choice I could make differently because of what I am learning?
That one choice might be the beginning of a preventive practice that serves you for years.
And if you have already tried the Just Eat Challenge, I would love to hear about that too. What have you noticed when you give a meal your full attention? Are you recognizing hunger or fullness differently? Are you tasting your food differently? Does eating without distraction change the pace of your meal or the way your body feels afterward?
Send me a note and tell me what you are learning.
Perhaps prevention doesn’t always begin with adding another practice, buying another product, or making another resolution. Perhaps sometimes, the best prevention is listening.
