Does Lighting Impact Concentration? 

Yes, lighting and concentration are more connected than most people realise. The brightness, colour temperature, and even positioning of light in your environment can influence how alert, focused, or mentally drained you feel during the day. 

How Lighting Affects Focus and Mental Performance 

Lighting plays a critical role in regulating circadian rhythms, mood, and cognitive function. Poor or overly harsh lighting, especially in work or study spaces, can cause eye strain, fatigue, and lapses in attention. This makes workplace lighting focus optimisation essential for productivity. 

Here’s how your visual environment attention may be impacted: 

Dim lighting:  

It can lead to drowsiness and reduced mental alertness. 

Harsh fluorescent lighting:  

May cause headaches, glare, and overstimulation, especially in those with sensory sensitivity. 

Natural light exposure:  

Improves mood, energy, and sustained attention levels. 

Inconsistent lighting:  

Flickering or uneven brightness distracts the brain and breaks focus. 

Small adjustments, like adding desk lamps with warmer tones, reducing glare from screens, or working near a window, can noticeably boost mental clarity. In shared or office environments, using task lighting or blue-light filters may help mitigate concentration loss. 

If focus challenges persist despite these changes, it might be worth considering underlying issues like ADHD.
