A person wearing large headphones is surrounded by various colorful and abstract elements, symbolizing a vibrant mix of creativity and discovery.

Sensory sensitivity is one of the most critical yet misunderstood aspects of human experience. For neurodivergent individuals—those whose neurological functioning differs from societal norms—sensory processing can be a source of profound challenges or unique strengths. Whether through heightened sensitivities (hypersensitivity), diminished responses (hyposensitivity), or even sensory-seeking profiles, these experiences shape how individuals perceive the world, interact with their environment, and regulate their attention, energy, and emotions.

As someone who has dedicated his career and the latter part of my life to neuroscience, assistive technology and app development, and advocacy for neurodiversity, sensory sensitivity is at the heart of my work. Inspired by our autistic daughter’s experiences navigating a world not designed for her needs, I have come to understand how vital it is to address sensory sensitivities thoughtfully and inclusively. This blog post explores why sensory sensitivity matters—not just for neurodivergent individuals but for society as a whole—and offers actionable strategies for creating environments where everyone can thrive.

The Science Behind Sensory Sensitivity

Sensory sensitivity refers to how individuals process stimuli from their environment through their senses. While most people are familiar with the five traditional senses—sight, sound, touch, taste, smell—there are additional senses that play an equally important role in sensory processing:

Proprioception: The sense of body awareness and positioning.
Vestibular Sense: The sense of balance and spatial orientation.
Interoception: The sense of internal body states like hunger, thirst, or pain.

For neurodivergent individuals—such as those with autism spectrum condition (ASC), attention deficit hyperactivity disorder (ADHD), epilepsy, or sensory processing disorder (SPD)—these sensory systems often function differently than they do in neurotypical people. These differences can manifest as:

Hypersensitivity: An increased sensitivity to stimuli. For example, bright lights may feel blinding or loud sounds overwhelming.
Hyposensitivity: A decreased sensitivity to stimuli. Individuals may seek out intense sensory input, such as strong flavors or deep pressure.
Sensory-Seeking: Actively looking for experiences that stimulate touch, sound, sight, taste, and movement. For example, spinning, jumping, or seeking out tactile experiences like playing with play dough or sand. These are not merely playful; they serve a crucial purpose in helping the individual regulate their sensory experiences and maintain a sense of equilibrium.

These variations are not inherently problematic but become challenging when environments fail to accommodate them. Understanding these differences is essential for creating spaces where neurodivergent individuals can thrive.

The Neurological Basis

Sensory processing differences stem from variations in how the brain interprets signals from sensory organs. Research has shown that certain areas of the brain—such as the amygdala (which processes emotions) or sensory cortex—may be hyperactive or under active in neurodivergent people. This can lead to heightened emotional responses or difficulty filtering out irrelevant stimuli. For example:

Autistic studies have reported atypical connectivity between sensory regions of the brain and other areas involved in attention and emotion regulation.
ADHD research suggests sensory modulation may contribute to behaviors like fidgeting or seeking stimulation.

These neurological differences underscore why sensory sensitivity should be viewed not as a deficit but as a unique way of experiencing the world.

How Sensory Sensitivity Impacts Daily Life

Sensory sensitivity influences nearly every aspect of life—from education and work to social interactions and emotional well-being, including:

1. Education

Classrooms are often designed with neurotypical students in mind: fluorescent lighting, crowded seating arrangements, and constant background noise are common features that may overwhelm students with hypersensitivity. Conversely, students with hyposensitivity may struggle to stay engaged without sufficient sensory input. For example:

A child hypersensitive to sound might find it impossible to focus during group activities due to chatter or scraping chairs or chalkboards.
A child with hyposensitivity might benefit from movement breaks or tactile learning tools like sandpaper letters.

2. Workplaces

Work environments present similar challenges, including:

Open-plan offices can be overwhelming for employees sensitive to noise or visual clutter.
Bright lighting or strong odors (e.g., perfumes) may trigger discomfort or migraines in those with hypersensitivities.

Employers who prioritize sensory-friendly accommodations—such as quiet zones or remote work options—not only support neurodivergent employees but also foster productivity and well-being across their teams.

3. Social Settings

Social interactions often involve unpredictable sensory inputs that can be distressing for neurodivergent individuals:

Crowded events like concerts or parties may provoke anxiety or fatigue due to overwhelming stimuli.
Certain textures in clothing or food may make socializing uncomfortable.

Understanding these challenges helps create more inclusive social spaces where everyone feels welcome.

4. Emotional Regulation

Sensory experiences are closely tied to emotional regulation. Overwhelming stimuli can exacerbate feelings of anxiety or irritability, while calming inputs—like soft textures or soothing sounds—can promote relaxation. For instance:

Weighted blankets provide deep pressure that helps regulate anxiety by activating the parasympathetic nervous system.
Noise-canceling headphones allow individuals sensitive to sound to potentially participate in noisy environments without feeling overwhelmed.

Recognizing this connection is key to supporting neurodivergent individuals in managing stress effectively.

A Personal Perspective: Why This Work Matters

My understanding of sensory sensitivity is deeply personal—it stems from my experiences as a father advocating for our daughter Phoebe. Diagnosed with autism, ADHD, and epilepsy at an early age, Phoebe continues to face profound hypersensitivities that affect her ability to navigate everyday environments.

From fluorescent lights in stores that cause her physical discomfort to certain fabrics she cannot tolerate wearing, Phoebe’s world is shaped by her unique sensory profile. These challenges inspired me to develop ethical wearable devices and apps designed specifically for real-time sensory regulation—technologies that empower individuals like Phoebe without asking them to mask their authentic selves.

This work matters because it goes beyond addressing discomfort; it’s about giving people agency over their environments so they can thrive on their own terms.

Creating Sensory-Friendly Environments

Addressing sensory sensitivity requires proactive efforts across various settings—homes, schools, workplaces, public spaces—and involves both physical changes and cultural shifts toward inclusivity.

1. Lighting Adjustments

Use lights for sensory sensitivity, dimmable lamps or natural light instead of harsh fluorescent bulbs.
Offer light filters or warm-toned LEDs that reduce glare.
Provide individual control over lighting where possible (e.g., desk lamps).

2. Sound Management

Incorporate soundproofing materials into walls/ceilings.
Offer specific apps that use existing headphones or earplugs.
Designate quiet zones free from background noise (e.g., libraries).

3. Tactile Considerations

Use soft furnishings made from breathable fabrics.
Provide fidget tools/toys for tactile stimulation during meetings/classes.
Avoid scratchy materials when designing uniforms/clothing policies.

4. Flexible Policies

Allow remote work options if office environments prove overwhelming.
Implement movement breaks during long meetings/classes.
Encourage open dialogue about individual needs/preferences without stigma attached.

Technology’s Role in Supporting Sensory Needs

Technology offers powerful tools tailored toward managing diverse sensory profiles:

Wearable devices like smartwatches track physiological responses (e.g., heart rate variability), enabling users real-time feedback during stressful situations.
AI-driven platforms suggest personalized accommodations based on user data patterns over time (e.g., recommending noise-canceling headphones).
Assistive apps guide mindfulness exercises tailored toward calming overstimulated nervous systems effectively!

The Role of Technology in Supporting Sensory Needs

Technology has become a game-changer in addressing sensory sensitivity. For neurodivergent individuals, assistive technologies can provide tools for managing overwhelming environments, enhancing autonomy, and improving quality of life. Here are some ways technology is making a difference:

1. Wearable Devices

Wearable devices designed for sensory regulation are transforming how individuals manage their sensory needs in real time. Examples include:

Noise-Canceling Headphones: These block out overwhelming auditory stimuli, making noisy environments like airports or offices more tolerable.
Weighted Wearables: Weighted vests or blankets provide deep pressure stimulation, which can help calm the nervous system during moments of stress.
Smart Glasses: Glasses that filter blue light or reduce glare can mitigate visual hypersensitivities caused by fluorescent lighting or digital screens.

In my work as a neuroscientist and entrepreneur, I’ve developed ethical wearable devices and apps that not only accommodate sensory needs but also empower users to take control of their environments. These devices are co-designed with neurodivergent people to ensure they address real-world challenges and respond to your lived experiences.

2. AI-Driven Platforms

Artificial intelligence (AI) is another powerful tool for supporting sensory needs. AI-driven platforms can:

Monitor physiological responses (e.g., heart rate, skin conductance) to detect signs of sensory overload.
Provide personalized recommendations for accommodations, such as suggesting specific alerts, dynamic or frequency canceling filters, or gentle text-to-speech guidance when auditory stress, distraction, or fatigue is detected.
Learn individual preferences over time to offer tailored solutions for managing sensory sensitivities.

For example, an AI platform might alert a user to take a break from a visually overstimulating environment or suggest calming exercises during moments of heightened stress or tiredness.

3. Assistive Apps

Mobile apps designed for mindfulness, relaxation, and sensory regulation are widely available and accessible. Examples include:

Calming Apps: Apps like Calm or Headspace guide users through breathing exercises, meditation, or progressive muscle relaxation.
Sensory Input Tools: Apps that simulate soothing sounds or music (e.g., rain, ocean waves) or provide visual stimuli (e.g., calming animations) can help individuals self-regulate during moments of overload.
Customizable Alerts: Some apps allow users to set reminders for hydration, movement breaks, or other self-care activities that support sensory regulation.

Technology is not a replacement for human understanding but an enabler of autonomy and comfort. By integrating these tools into daily life, neurodivergent people can navigate their environments with greater ease and confidence.

Advocacy and Collaboration

Creating a world that accommodates sensory sensitivity requires collective effort across multiple sectors—education, employment, healthcare, architecture, and public policy. Advocacy plays a critical role in driving this change by raising awareness and promoting inclusive practices.

1. Advocacy in Education

Schools are often the first environments where neurodivergent children encounter barriers related to sensory sensitivity. Advocates can push for:

Sensory-Friendly Classrooms: Incorporating quiet zones, dimmable lighting, and fidget tools into classrooms ensures that students with diverse sensory needs can focus and learn effectively.
Teacher Training: Educators should receive training on recognizing signs of sensory overload and implementing accommodations tailored to individual students.
Individualized Education Plans (IEPs): IEPs should include specific strategies for addressing sensory sensitivities, such as allowing noise-canceling headphones during tests or providing movement breaks throughout the day.

2. Advocacy in Workplaces

Employers must evolve to accommodate employees with sensory sensitivities. This includes:

Encouraging flexible work arrangements (e.g., remote options or adjustable schedules).
Designing offices with quiet zones and customizable workstations.
Offering employee resource groups (ERGs) where neurodivergent people can comfortably share experiences and advocate for change internally without fear of retaliation or scorn.

3. Advocacy in Public Spaces

Public spaces—such as parks, transportation systems, and retail stores—should be designed with universal accessibility in mind. Advocates can do better promoting beyond impractical sensory-friendly hours to include:

Accommodations at stores or museums (e.g., dimmed lights and reduced noise levels).
Clear signage that helps individuals navigate spaces without feeling overwhelmed.
Inclusive design principles that prioritize accessibility for all users.

4. Collaboration Across Sectors

Among caregivers, healthcare providers, educators, employers, architects, and policymakers, joint efforts are essential for creating systemic change, for example:

Healthcare providers can work with educators to develop sensory-friendly accommodations for autistic children.
Architects can collaborate with neurodivergent people to design buildings that minimize sensory triggers.
Policymakers can enact legislation mandating accessibility standards that account for sensory sensitivities.

By working together across disciplines, we can all participate in creating meaningful environments where everyone—not just neurodivergent people—feels supported and included.

Celebrating Neurodiversity

A neurodiversity-affirming approach shifts the narrative from "fixing" differences to celebrating them as valuable aspects of human diversity. Sensory sensitivities are not deficits but unique ways of experiencing the world that often come with strengths worth recognizing.

1. Unlocking Hidden Talents

Many neurodivergent individuals possess exceptional talents shaped by their unique sensory profiles:

Those with heightened visual processing may excel in graphic design or photography.
People with auditory sensitivity might thrive in music production or sound engineering.
Those seeking tactile input bring creativity to professions like sculpture or textile arts.

By accommodating sensory needs rather than suppressing them, we may unlock talents often overlooked due to unhelpful environments.

2. Fostering Creativity

Diverse perspectives lead to innovation. Neurodivergent people approach challenges differently due to their unique processing strategies—a trait that fosters creativity in fields ranging from technology to the arts. For example:

Temple Grandin’s hypersensitivity to visual details enabled her to revolutionize livestock handling systems by designing humane facilities based on how animals perceive their environments.
Greta Thunberg’s autism allows her to focus intensely on climate change advocacy without being swayed by societal norms.

These examples illustrate how embracing neurodiversity enriches all of society.

The Future of Sensory-Inclusive Design

As awareness grows around sensory sensitivity, there is immense potential for innovation in design and policy:

Architecture: Future buildings could feature adjustable acoustics, customizable lighting systems, and designated quiet zones tailored to diverse sensory profiles.
Urban Planning: Cities may incorporate green spaces (which have calming effects) while reducing overstimulating elements like excessive signage or loud traffic noise.
Product Design: Consumer products—from clothing to furniture—could be designed with greater tactile comfort, offering options for hypersensitive people.
Legislation: Governments can mandate accessibility standards that account for physical disabilities and invisible conditions like autism, ADHD, and epilepsy.

The future lies in creating environments where everyone—not just neurodivergent individuals—can thrive comfortably.

Conclusion: Building a More Inclusive World

Sensory sensitivity matters because it shapes how people experience life—and no two experiences are alike. For neurodivergent individuals, these sensitivities are not mere inconveniences but integral aspects of their identity. By understanding and accommodating these needs:

We affirm the value of neurodiversity.
We empower individuals to live authentically without fear of judgment or exclusion.
We enrich society by fostering empathy, creativity, and inclusivity.

Whether through technological innovations like apps or wearable devices or simple acts like dimming lights in shared spaces—we all have a role in building a more inclusive world where everyone feels seen, heard—and most importantly—understood.

In honoring the importance of sensory sensitivity today, we take one step closer toward a society where every individual’s unique way of experiencing life is celebrated rather than suppressed.
