Designing workspaces for optimal focus, productivity and creativity - Light

The first in a series of articles, we look at the role light can play in creating the optimal workplace conditions to foster creativity, productivity and focus.

Wherever you work from, ensuring optimal working conditions is an effective way to inspire productivity, creativity and focus in yourself, your employees, or your colleagues. From the air you breathe to the arrangement of your furniture, there is a whole range of metrics that induce natural biological responses, which can be harnessed to do better, more effective work.


In this article, we explore the impact of light, and what steps you can take to optimise your workplace design through the best use of light.


Let there be light

It’s almost a given that your workspace should be bathed in light. It is pretty difficult for normally sighted individuals to work well in the dark and we have all been warned about staring at bright screens in poorly lit rooms, but apparently there is a bit more to it than that.


Speaking on his podcast, American neuroscientist and Stanford University professor Dr. Huberman notes the biological impact light has on your body, and how the right light conditions can induce better focus and productivity. For the first six to nine hours after waking up, your brain is producing high levels of dopamine and epinephrine, which establish a unique state of alertness – caffeine, or not.


This state can be maintained by providing high levels of light, especially overhead light. This is because eye neurons are mainly enriched in the lower half of your retinas, which view the upper field of vision. Keeping your upper field of vision light therefore causes the continued release of chemicals, to facilitate more focus.


Optimising your workspace

Sunlight is the king when it comes to overhead lighting, but it’s not always the most practical. In the office, it is worth investing in high quality overhead lighting that maintains bright full coverage of areas where focused work will take place.


Where you can take advantage of sunlight, place desks as close to windows as possible, but do think about the daily progression of the sun and any impact it may cause when it comes to screen glare or shining into people’s eyes. If you can open your window, then even better, as closed windows can be up to 50 times less effective than open windows due to the filtering of blue light, which is key to the process.


If you work from home, make sure your ceiling light is appropriate. Many homes are designed with more mood lighting, with some shades reducing overhead light to a more relaxed ambience. Consider switching out to a brighter fitting to help bump up your natural chemical production.


It is important to get the balance and type of light right, especially as peoples light sensitivity can differ. Contrary to popular believe overly bright fluorescent or halogen lighting cannot cause migraines, but it does seem to make regular sufferers feel worse, and can negatively effect the ambience of poorly designed workspaces. LED lighting is a good choice as not only is it more energy-efficient and longer lasting, it can be easily dimmed to adjust to the right level.

The colour of light

We’ve all played with a light prism at school, and understand that white light is in fact made up of a whole rainbow of colours – but why do different colours of light matter in the workplace?


Blue light reduces the production of melatonin, a chemical that supports sleep. More blue light equals more alertness and less sleepiness. A study by the University of  Greenwich found that blue-enriched light bulbs made staff members feel happier and more alert, and they experienced much less eye strain.


Optimising your workspace

Warmer lighting such as red or yellow/white hues does not inhibit the same physiological responses. By turning to these lights as the day wears on, they allow your body to work its natural course, which in turn keeps people happy and motivated. They are also often preferred in work environments such as client meeting rooms or places to eat as they provide a more comfortable, relaxed atmosphere.

Daily Rhythms

With light, it is key to follow your natural circadian rhythm. Your body is shifting from dopamine to serotonin and other neuromodulators, which are better for creative and abstract thinking. Naturally, as the day wears on, the sun begins to lower. Mimicking this with your workspace light helps to maintain a healthy chemical balance, allowing you to work to effective levels. By providing the wrong light levels, you can disrupt your natural rhythms, causing loss of concentration and poor productivity.


Optimising your workspace

In the afternoon, light levels should be brought down, with desk lighting introduced and overhead lights made dimmer. If possible, more warm yellow lighting should be preferred in the afternoons instead of blue lights.


Screen brightness

Most office workers will use a computer all day long. Moderating brightness levels should be a standard part of any lighting strategy. One important part of keeping your workspace light during the early part of the day is to ensure your screen isn’t overly bright in comparison.



AS the day wears on and your overall workspace will dimmer down dimmer, meaning you should look to reduce screen brightness, and if possible, lower blue lighting specifically. You can set this to automatic on many devices (My mobile phone is set to automatically remove blue light from 8pm onwards) and once set can be left to do its thing.
