Over a third of workers are adversely affected by a lack of natural light in their office, according to new findings.
The poll, which quizzed employees about the difficulties associated with workplace lighting, revealed that headaches and dizziness were a problem for one in seven.
Other employees reported finding the lighting too bright and dazzling (12.4%), while one in 10 said they had to strain their eyes due to a general lack of light.
A similar proportion said they were bothered by the position of the lights and by the ‘stressful environment’ created by their workplace lighting (9.3% each).
The findings come as reports of ‘sick building syndrome’ — a condition associated with office work that causes symptoms including headaches and respiratory problems — continue to hit the headlines.
Such symptoms are usually attributed to unhealthy or stressful elements of the working environment, such as poor ventilation and lighting.
And according to the latest figures, an estimated 137.3 million working days were lost due to sickness or injury in the UK in 2016 — or 4.3 days per worker — the most common reason for which was minor illnesses.
Many of the ailments synonymous with sick building syndrome, including headaches and dizziness, can be reduced through changes to lighting in the room.
Fluorescent tubes in offices are often cited as a source of complaint. Many companies now opt for LED panels, which produce light with a far lower Unified Glare Rating, reducing discomfort for employees.
Rob Holroyd, digital marketing manager at Lamp Shop Online, which carried out the survey, said:
“What many employers and facilities managers are continuing to neglect is that the fluorescent tube lights commonly used in offices are likely to be causing harm to employees, in one way or another, on a daily basis.
“Not only do they create glare and cause headaches, they’re seldom replaced when needed, forcing staff to work in darkness, which in turn strains their eyes.
“Where possible, natural light should be maximised in the workplace since it’s proven to benefit the health and wellbeing of employees. But thanks to advances in lighting solutions, such as the development of low-glare LED panels, poor office lighting need no longer be the cause of physical or mental health complaints.”
Panels are also available in a range of ‘colour temperatures’ to suit different environments. The higher the colour temperature (in Kelvin), the cooler the light — or the closer to natural daylight.
A colour temperature of 4,000 Kelvin is preferred in most office environments due to its crisp white working light, while 6,000 Kelvin imitates daylight more closely and is therefore favoured in some workplaces.
