Leolightdesign specialises in Light and Health. Both Lighting Consultants have researched
the effects of light on health and wellbeing and incorporate their lighting research
knowledge in the benefits of light on health into healthy lighting designs. We aim
to fill your living and working environment with light vital for a good quality life
and a high standard lifestyle.
The invention of electricity has provided us with the means to generate artificial
lighting, which has enabled us to spend most of the day and night indoors. As we
no longer dependent on natural light with its seasonal conditions and have gravitated
more towards an indoor lifestyle under artificially lit conditions, people are missing
out on natural daylight and sunlight.
Lack of light starves our body
However, there is a vast difference when comparing the light levels we receive outside
with the level of light we get under artificial lighting. On an over cast day the
light levels can be anything from 5,000 -10,000 lux compared with 500 – 1,000 lux
in an interior environment that is lit with artificial lighting.
We must understand that artificial light lacks spectral qualities present in natural
light. A lifestyle under artificial lighting starves the body of vital light energies
when insufficient lighting, like low light levels as well as poor quality of light,
Insufficient lighting causes health problems
Lighting research shows that people who work under artificial lighting conditions
for a prolonged period, which lack the right quantity and/or quality of light, complain
of feeling tired, lethargic, less motivated and less productive. In some cases it
has resulted in absenteeism in the work place.
Do we starve our bodies with insufficient light and lighting?
