We complain about the short day length in winter but in many ways we are immune to the seasons as we move through our 21st-century, technological lives.
Yet light and day lengths remain important to our state of mind. The seasonal fluctuations have an impact as the actual wavelengths present and daylight varies from one day to another. They also vary depending on latitude, meteorological conditions and the seasons. SAD syndrome is definitely a reality for many people in winter.
That’s just a part of its importance to all life. Research demonstrates light has a fundamental impact on human health. It controls the body’s circadian system and certainly impacts on our moods and perception.
Block lighting managers will sense the change in atmosphere when lights are out in corridors. The whole tone in a building changes. It gives off all kinds of messages too about not valuing residents and this may well prompt them to take less care also.
With contemporary lighting solutions we can improve the way humans perform visual tasks and function within their environments. The more light that can be thrown on the subject, the better we function.
This is especially true with age. Eyesight deteriorates more rapidly after the age of 45. So with an ageing population in the UK, who will live far longer, it’s essential care is taken when designing lighting systems.
Consideration regarding who will be using a block or how they might be using it should be part of the design spec and conversation before anything is installed. After all it might even save money for health care in general.
How? By increasing light levels, depression is often reduced. This might impact on medicines prescribed and even how long people stay in hospital. Even dementia patients are shown to be less agitated when light levels are controlled effectively.
It also prevents trips, falls and other accidents. But it’s not just about artificial light. Anyone unlucky enough to work in an office without natural light will know the negative impact that has on mood and overall health. Next time you look out the window or step outside into sunlight, appreciate it. Certainly your body and mind will thank you for it.
If artificial light is the only option make sure it’s well-designed, fit for purpose and runs efficiently to suit everyone’s needs.
