Lighting for Neurodiversity

Why Lighting Matters for Neurodiversity

It is well recognized that interactions between a person and the surroundings in which they perform everyday duties influence human behavior and performance. Each of us has unique sensory thresholds and processing preferences that affect how we perceive and engage with the world around us. This can lead to being “over-sensitive” or “under-sensitive” to sensory parts of the environment or even getting overwhelmed by sensory input for neurodivergent people, whose abnormalities in sensory processing are frequently more noticeable.
Neurodiversity encompasses people with autism spectrum disorder (ASD), ADHD, sensory processing challenges, and other cognitive differences—and while around 1 in 100 people worldwide are diagnosed with autism, the actual number is likely higher, as many individuals remain undiagnosed.

Traditional lighting solutions—like flickering fluorescent tubes, high-intensity LEDs, or harsh glare from reflective surfaces—can lead to sensory overload, anxiety, headaches, and discomfort. Public spaces like libraries, healthcare facilities, airports, and schools can unintentionally make it difficult or uncomfortable for neurodiverse people to use and enjoy them.

As a result, when creating their workplaces, organizations need to consider how sensory elements affect the surroundings.

Planning Lighting for Neurodiverse-Friendly Spaces

Creating neurodiverse-friendly lighting does not mean overhauling every bulb in your building. Often, small changes can make a big difference.

At Kaash Light Engineers, we specialize in creating neurodiverse-friendly lighting solutions. We offer a curated collection of fixtures—like the Lofty Reflex for soft, diffused light and Zoom Spots for precision control—that enhance comfort, reduce sensory overload, and promote inclusivity in public spaces.

Here’s how to plan lighting that truly includes everyone:

Adjustable Lighting Systems

Allow users to control the light intensity with dimmable systems. What works for one person may not work for another, so accommodating different needs is key. Offering control over light color—ranging from warm to cool—lets individuals customize their environment.

Say Goodbye to Flicker

Fluorescent lights, often used in public spaces, are notorious for flickering. While it may go unnoticed by some, neurodiverse individuals can find it incredibly distracting or even painful. Switch to flicker-free LED lighting for a smoother experience.

Uniform, Glare-Free Lighting

Uneven lighting and glare can create visual distractions, making it hard for neurodiverse individuals to focus. Indirect lighting, diffusers, and matte finishes help reduce these issues by keeping illumination balanced across the space.

Incorporate Natural Light

Natural light is a mood booster, but it’s essential to manage glare. Use shades or blinds to control outdoor light, offering a calming view without overwhelming brightness. Incorporate natural light where possible—but when it is not, mimic its soothing qualities with soft, diffused lighting from our collection.

Prioritize Personalization

The ability to customize one’s environment is one of the most inclusive tools available. For example, consider creating areas with varied lighting options, such as quiet rooms lit by warm, dim lights for respite from more brightly lit sections.

Benefits of Neurodiverse-Friendly Lighting

The benefits of inclusive lighting reach far beyond neurodivergent individuals. When spaces are comfortable and adaptable, everyone thrives. Here’s how thoughtful lighting design makes an impact:

• Improved Focus and Productivity: Neurodivergent individuals may struggle to focus in poorly lit spaces. Customizable lighting improves concentration and performance.
• Reduced Anxiety and Stress: A calm, well-lit space can significantly lower anxiety levels, especially in individuals prone to sensory overload.
• Greater Inclusivity: When lighting accommodates everyone, it fosters a sense of belonging. Neurodivergent individuals are more likely to engage with businesses or spaces that consider their needs.
• Better Overall Mood: Whether you are neurodiverse or not, lighting influences mood. Warm, soft light can create a soothing atmosphere for everyone.

Research-Backed Insights

According to recent studies, lighting and environmental design are crucial for helping neurodiverse people. According to the studies, the ideal balance for accommodating a wide range of sensitivities is provided by neutral surroundings with optional stimulating characteristics. Variability, adaptability, and user control were important themes that enabled people to modify their environment according to their requirements. Furthermore, it has been demonstrated that switching from fluorescent lighting to incandescent or halogen alternatives enhances behavior, engagement, and attention (Nair & Priya, 2022) (Sadia, 2020).

Additionally, inclusive design practices in workplaces have shown that productivity can increase by as much as 30% when neurodiverse employees are supported. These findings extend beyond offices to schools, retail spaces, and public buildings, underlining the importance of accessibility in lighting design.

Key Design Takeaways from Research:

• Warm color temperatures (2000K to 4000K) are generally more comfortable than harsh white light.
• Uniform lighting reduces distractions caused by shadows or bright spots.
• Providing options and flexibility appeals to a wide range of sensory needs.
