For many people with ADHD, lighting can make the difference between focus and fatigue. It is not just about brightness; it is about how light affects sensory comfort, dopamine regulation, and executive function. According to NICE guidance (NG87), lighting adjustments, there is a recognised environmental modification that can reduce distraction and support sustained attention in ADHD.

Why Light Matters for ADHD Brains 

The Royal College of Psychiatrists (2023) notes that adults with ADHD often have heightened sensitivity to artificial light, especially fluorescent or blue-enriched tones. These can trigger eyestrain, irritability, and restlessness (RCPsych, 2023). The NHS England ADHD Taskforce (2025) recommends sensory-friendly workspaces with adjustable or natural light to help regulate arousal and prevent cognitive fatigue. 

Consistent, warm lighting improved attention and decision-making in adults with ADHD, while irregular or harsh lighting disrupted prefrontal cortex activation and slowed reaction time. 

How to Optimise Lighting for Focus and Comfort 

Occupational therapy guidance from RCOT (2023) and NHS sensory-processing programmes offer several practical, evidence-based steps: 

Use natural or warm light  

Position desks near windows when possible. Warm tones help calm the nervous system and support the circadian rhythm. 

Avoid harsh fluorescents  

Choose diffused LEDs or shaded lamps to prevent flickering and glare. 

Layer lighting  

Combine ambient, task, and accent lighting for flexibility during different times of day. 

Control of brightness  

Dimmable lights give personal control over stimulation levels. 

Incorporate sensory zoning: Brighter areas for focus tasks, softer light for rest or reflection. 

Behavioural and environmental support programmes such as Theara Change integrate CBT-style coaching with sensory awareness training, helping individuals identify how lighting and other sensory inputs influence their focus, energy, and wellbeing. 

The Takeaway 

Lighting is more than an aesthetic detail; it is a form of environmental therapy. According to NICE and NHS guidance, maintaining balanced, adjustable, and natural lighting reduces overstimulation, improves concentration, and supports healthy dopamine rhythms for people with ADHD. Even small changes to light quality can create a more productive workspace.
