Harvard researchers conducted an experiment comparing the effects of 6.5 hours of exposure to blue light to exposure to green light of comparable brightness.  The results were clear: blue light suppresses the production of melatonin (the sleep hormone), which disrupts the circadian rhythm (our body clock). The researchers postulate that the mechanism exists to make humans spur into action when they see the beautiful blue sky in the morning.  Artificial lighting often emits a large amount of blue light, and most of us are using this lighting right up until bedtime.

The researchers believe that using artificial lighting before bed disrupts our sleep and circadian rhythm. Poor quality sleep has been linked to a myriad of negative health conditions including depression, diabetes and cancer. So how can we avoid this?

In our homes, solutions include:

  • Avoid looking at bright screens two to three hours before bed. Alternatively, investigate a piece of software called f.lux which adjusts the blue light emission of your monitor to match the current output of the sun.
  • Use dim red lights at night time. Red light mimics the sunset and can relax the body, getting it ready for sleep. Alternatively, you could invest in some groovy looking blue blocking sunglasses and wear them around the house at night.
  • Expose yourself to lots of bright daylight during the day, which will boost your ability to sleep at night.

The best solution is to experience The Photon Space. Living inside the glass house you will fully experience the sunset and the artificial lighting at night time emits no blue light. The Photon Space takes every measure to ensure you have the best night sleep of your life.
