Health is a matter of design… with Lights

As the world around us is undergoing rapid technological revolution, we are spending an increasing amount of time indoors. Workspace demands, climactic changes – all contribute to us denying ourselves of the natural light our body needs.

Does this mean that we have to compromise on our wellbeing?

WELL Standards to the rescue!

The WELL Building Standard is a performance-based system for:

  • measuring
  • certifying
  • monitoring

features that impact the health and human wellbeing in any space.

It is managed and administered by the International WELL Building Institute (IWBI), and outlines clear directives on how different parameters of a building should be maintained to assure the wellbeing of the occupants

Light is evidently one of these parameters.

Effects of light on wellbeing

Light has a direct correlation on the physical, mental and emotional health of the recipient. Our body is an outcome of 70,000 years of evolution, and its responses to light will be more in line with this than with the last 50 years of technological revolution.

Impact on Physical Health

Everyone’s body is attuned to the natural sunrise and sunset cycle of the day. This rhythm of our body is called the Circadian Rhythm. As the day progresses, the natural light emitted by the sun changes in color, angle and intensity. The body requires both periods of brightness and darkness at appropriate points throughout the day to maintain optimal circadian rhythm.

Disruption to this circadian rhythm can cause problems like diabetes and obesity.

Impact on Mental and Emotional Health

Light is a powerful neurobiological agent. Studies have shown that lack of good lighting can result in chronic depression. Exposure to bright white light during the day can reverse this to an extent.

What should workspace lights do for you?

A well-designed lighting system should

  • making better use of existing lights
  • making sure that all lights are clean and in good condition
  • ensuring that lights are positioned correctly for each task
  • making the best use of natural light

It should adapt to the natural daylight according to the Circadian Rhythm. While a good portion of this has to do with lighting controls, the design of the lighting sources also play a huge role in this.

A WELL Lighting Source

Some of the main factors to consider in a lighting source are:

Visual Lighting Design – The source should provide good visual acuity (clarity of vision) and offer task lighting (illuminance for accomplishing a specific task).

Electric Light Glare Control – Luminaire shielding for minimizing glare and improving visibility should be incorporated.

Colour Quality – The lighting source should have optimized CRI (Colour Rendering Index which is a measure of the ability of the source reveal the colours of an object as closely as when viewed under natural light).

Circadian Lighting – The lighting source should be easy to integrate in a system that can mimic the body’s circadian rhythm.

At Arraystorm, we constantly strive to create products that offer the healthiest lighting an occupant can experience. Our Lineage, Fabia, Swank, Astro are compliant to the above standards, and are highly sought after for these benefits.

Healthy Lighting isn’t Heavy Lighting

Of course, poor lighting is a strict no for any organization. Not only can it lead to safety risks and hazards, it also causes people to feel lethargic, irritable and at times, depressed. The solution, however, does not lie in merely adding more light fixtures that glare the eyes out.

A lighting system should be designed intelligently to cater to the physical needs of the employees. There must be a balance between natural light and artificial light. It must be sensitive to the scope of work in a given section.

As per the International Labour Organization (ILO), a good lighting system doesn’t mean that you need more lights. It is often a merely a case of:
