LIGHT AND HEALTH lack of light right lighting

Modern indoor 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, is present.

 

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?
