Every moment of every day, your brain is processing an extraordinary amount of sensory information. The hum of fluorescent lights, the texture of your clothing against your skin, the distant sound of traffic, the subtle scent of coffee brewing in the next room—all of these sensations compete for your attention, requiring your nervous system to filter, prioritise, and respond appropriately. This remarkable process is called sensory regulation, and when it works well, we barely notice it happening. But when it doesn’t, the effects can be profound, touching every aspect of our mental health, learning capacity, and daily functioning.
Sensory regulation isn’t just a clinical concept reserved for therapy rooms and specialist clinics. It’s a fundamental human experience that affects how we feel in our own bodies, how we interact with others, and how successfully we navigate the demands of modern life. For children learning in busy classrooms, adults managing workplace stress, or anyone struggling with anxiety, understanding and supporting sensory regulation can be genuinely transformative.
One of the most exciting developments in supporting sensory regulation has been the growing recognition of how animals—particularly dogs—can play a powerful role in helping humans find their calm. The gentle pressure of a dog resting against your leg, the rhythmic motion of stroking soft fur, the grounding presence of a calm canine companion: these interactions offer something uniquely valuable that we’re only beginning to fully understand and appreciate.
What Exactly Is Sensory Regulation?
Sensory regulation refers to the brain’s ability to manage and respond appropriately to sensory input from our environment and our own bodies. This includes the familiar five senses—sight, sound, touch, taste, and smell—but also extends to three often-overlooked sensory systems that are equally crucial for our wellbeing.
The Eight Sensory Systems
Beyond the traditional five senses, our bodies rely on three additional sensory systems that significantly impact regulation:
- Proprioception: This is your body’s awareness of its position in space. Proprioceptive input comes from receptors in your muscles, joints, and tendons, telling your brain where your limbs are without you needing to look at them. Activities that provide proprioceptive input—like carrying heavy objects, pushing, pulling, or receiving firm hugs—are often deeply calming.
- Vestibular sense: Located in your inner ear, this system detects movement and changes in head position. It’s responsible for your sense of balance and spatial orientation. Some people find movement soothing, while others may feel overwhelmed by certain types of motion.
- Interoception: This internal awareness system helps you recognise signals from inside your body—hunger, thirst, temperature, heart rate, and the need to use the toilet. Strong interoceptive awareness is closely linked to emotional regulation, as recognising physical sensations is often the first step in identifying and managing emotions.
When all these systems work together harmoniously, we experience a state of regulation—we feel alert but calm, able to focus and engage with our environment appropriately. When sensory processing becomes disrupted or overwhelmed, we may experience dysregulation, which can manifest as anxiety, irritability, difficulty concentrating, emotional outbursts, or withdrawal.
Signs of Sensory Dysregulation
Sensory dysregulation doesn’t look the same for everyone. Some individuals become over-responsive to sensory input, finding ordinary stimuli overwhelming or even painful. Others may be under-responsive, seeking out intense sensory experiences or appearing disconnected from their environment. Many people experience a combination of both, depending on the type of sensory input and their current state.
Over-Responsivity May Look Like:
- Covering ears in response to sounds others barely notice
- Avoiding certain textures in food or clothing
- Becoming distressed in crowded or busy environments
- Difficulty tolerating bright lights or certain visual patterns
- Strong reactions to unexpected touch
- Feeling overwhelmed by strong smells
Under-Responsivity May Look Like:
- Seeking out intense movement or physical activity
- Appearing not to notice pain or temperature extremes
- Craving strong flavours or crunchy textures
- Difficulty recognising hunger, thirst, or fatigue cues
- Seeming to need extra stimulation to stay alert
- Frequently touching objects or people
It’s important to recognise that sensory processing differences exist on a spectrum. Many people experience mild sensory sensitivities that don’t significantly impact their daily life, while others may have sensory processing disorder or experience sensory challenges as part of conditions like autism, ADHD, anxiety disorders, or trauma responses.
The Science Behind Sensory Regulation and the Nervous System
To understand why sensory regulation matters so much for mental health and learning, we need to consider the autonomic nervous system. This system operates largely outside our conscious control, managing essential functions like heart rate, digestion, and stress responses. It has two main branches:
The sympathetic nervous system activates our fight-or-flight response. When we perceive threat or danger, this system increases heart rate, releases stress hormones, and prepares our body for action. While essential for genuine emergencies, chronic activation of this system leads to anxiety, exhaustion, and difficulty learning or connecting with others.
The parasympathetic nervous system promotes rest, digest, and social engagement. When this system is dominant, we feel safe, calm, and able to connect. Learning, creativity, and relationship-building all happen most effectively when we’re in a parasympathetic state.
Sensory input directly influences which branch of the nervous system is active. Certain types of sensory experiences—particularly rhythmic, predictable, and grounding sensations—can help shift us from a stressed sympathetic state into a calmer parasympathetic one. This is where the magic of sensory regulation strategies lies, and it’s also where our canine companions enter the picture in the most beautiful way.
The Unique Role of Dogs in Supporting Sensory Regulation
There’s something almost alchemical about the way dogs can help humans regulate their sensory and emotional states. While many sensory regulation strategies involve tools or techniques, interacting with a calm, well-trained dog offers something uniquely alive and responsive—a form of co-regulation that humans have been benefiting from for thousands of years.
Deep Pressure and Proprioceptive Input
One of the most powerful ways dogs support sensory regulation is through deep pressure touch. When a dog lies across someone’s lap, leans against their body, or rests their head on a person’s feet, they provide firm, sustained pressure that activates proprioceptive receptors throughout the body. Research consistently shows that deep pressure touch reduces cortisol levels (the stress hormone) and increases oxytocin and serotonin (hormones associated with bonding and wellbeing).
For children in educational settings who struggle with sensory overload, having a therapy dog rest against them during challenging tasks can provide the regulatory input they need to stay calm and focused. Adults with anxiety often report that the weight of a dog on their lap helps them feel grounded and present in a way that’s difficult to achieve through other means.
Rhythmic, Predictable Sensory Experiences
Stroking a dog’s fur provides a rhythmic, repetitive sensory experience that is profoundly calming to the nervous system. The predictability of this motion—combined with the soft, warm texture of fur—activates the parasympathetic nervous system and can help regulate breathing and heart rate. Many people unconsciously slow and deepen their breathing while petting a dog, which further enhances the calming effect.
Listening to a dog’s breathing or heartbeat can have similar effects. Some therapy dog programmes encourage children to lie next to a resting dog and simply listen, providing auditory input that is both rhythmic and reassuring.
Warmth and Temperature Regulation
Dogs have a higher body temperature than humans (typically around 38-39°C), and their warmth can provide comforting sensory input that helps regulate our own bodies. For individuals who find warmth soothing, cuddling with a dog offers a natural, responsive heat source that adapts to their needs.
A Living, Responsive Presence
Perhaps what sets canine-assisted sensory support apart from other tools is that dogs are living beings who respond to us. A weighted blanket provides deep pressure, but a dog provides deep pressure while also adjusting their position, offering gentle licks, or sighing contentedly. This responsiveness creates a feedback loop of co-regulation, where the calm presence of the dog helps the human regulate, and the human’s growing calm in turn settles the dog.
Practical Strategies for Supporting Sensory Regulation
Whether or not you have access to a therapy dog, there are numerous evidence-based strategies for supporting sensory regulation in yourself or others. The key is understanding individual sensory preferences and building a personalised toolkit of strategies.
For Over-Responsive Individuals (Those Who Feel Overwhelmed)
- Create calm environments: Reduce visual clutter, use soft lighting, and minimise background noise where possible. Consider using noise-cancelling headphones or sunglasses when needed.
- Provide advance warning: Unexpected sensory input is harder to process. When possible, prepare for transitions and new environments.
- Use deep pressure: Weighted blankets, compression clothing, firm hugs, or spending time with a therapy dog can provide calming proprioceptive input.
- Establish predictable routines: Predictability reduces the cognitive load of processing constant novelty, freeing up resources for sensory processing.
- Create a sensory retreat: Having a quiet, low-stimulation space to withdraw to when overwhelmed is essential.
For Under-Responsive Individuals (Those Who Seek Sensory Input)
- Build movement breaks into the day: Regular opportunities for physical activity, jumping, spinning, or heavy work can help maintain optimal arousal.
- Offer varied textures: Fidget tools, textured objects, and opportunities to explore different tactile experiences can be helpful.
- Provide strong flavours and crunchy foods: These offer intense oral sensory input that some individuals find regulating.
- Use alerting sensory input: Cool temperatures, bright light, and upbeat music can help increase alertness when needed.
- Encourage body awareness activities: Yoga, martial arts, and animal-assisted activities can improve interoceptive awareness.
Universal Strategies
- Practice mindful breathing: Slow, deep breathing activates the parasympathetic nervous system. Try breathing in rhythm with a resting dog’s breath for added benefit.
- Stay hydrated and well-nourished: Physical needs directly impact our ability to process sensory information.
- Prioritise sleep: Fatigue significantly impairs sensory processing and regulation.
- Build in transition time: Moving between activities requires shifting sensory gears. Allow time for this adjustment.
- Engage with animals: Regular interaction with calm, well-trained dogs provides multi-sensory regulatory input that supports overall nervous system health.
Sensory Regulation in Educational Settings
For children and young people, the classroom environment presents constant sensory challenges. Fluorescent lighting, busy wall displays, the noise of other students, uncomfortable chairs, unexpected fire drills—all of these demand sensory processing resources that might otherwise be available for learning.
Progressive schools are increasingly recognising the importance of sensory-informed approaches. This includes creating calm corners or sensory rooms, allowing movement breaks, offering alternative seating options, and—in growing numbers of schools—incorporating therapy dogs into the learning environment.
School-based therapy dogs provide remarkable benefits for sensory regulation and learning. A child who struggles to settle at the start of the school day might spend ten minutes greeting the classroom dog, the rhythmic stroking helping to downregulate their nervous system and prepare them for learning. A student who becomes overwhelmed during a test might be allowed to sit next to the dog, whose calm presence and warm weight against their legs helps them stay regulated enough to demonstrate what they know.
Research from the University of British Columbia found that students who read aloud to therapy dogs showed significant reductions in cortisol levels compared to reading alone or to peers. This biological shift—from stress to calm—creates optimal conditions for learning and memory consolidation. The non-judgmental presence of the dog, combined with the sensory benefits of physical contact, creates a virtuous cycle of regulation and confidence.
Sensory Regulation and Mental Health
The connection between sensory regulation and mental health is bidirectional and powerful. Poor sensory processing can contribute to anxiety, depression, and emotional dysregulation, while mental health challenges can impair our ability to process sensory information effectively.
For individuals with anxiety disorders, sensory sensitivities often intensify during periods of heightened stress. What was tolerable background noise becomes unbearable; textures that were merely uncomfortable become intolerable. This creates a feedback loop where sensory overload increases anxiety, which increases sensory sensitivity, which increases anxiety further.
Trauma can also profoundly impact sensory processing. The nervous system of someone who has experienced trauma may be hypervigilant, constantly scanning the environment for threat and over-responding to sensory input that resembles past danger. Sensory-informed approaches are increasingly recognised as essential components of trauma-informed care.
Here, too, dogs offer something special. Therapy dogs used in mental health settings provide a unique form of support that addresses both emotional and sensory needs simultaneously. The dog’s calm presence helps co-regulate the human’s nervous system while their warmth, weight, and texture provide grounding sensory input that anchors attention in the present moment—a powerful antidote to both anxiety and trauma responses.
Our understanding of sensory regulation continues to grow, revealing ever more clearly how fundamental it is to human wellbeing, learning, and connection. In a world that bombards us with sensory information at unprecedented levels, the ability to regulate our responses to this input has never been more important. And in this essential work, we are fortunate to have partners who have walked beside humanity for millennia—our dogs, whose simple, steady presence offers a form of regulation that no technology can replicate. Whether in schools, therapy settings, or our own homes, these remarkable animals remind us that sometimes the most powerful interventions are also the most natural: warmth, weight, rhythm, and the gift of being together.
