Blue Light Blocking Glasses
We evolved in tune with the natural rhythms of the Earth. The movements of the sun, moon and earth control all our biological functions including hormones, sleep/wake cycles, metabolism and behaviour. Through millions of years of evolution, we were only exposed to blue light from the sun in the morning. This would signal to our bodies to release a hormone called cortisol to prepare us for the day. As the day goes on, the sun’s spectrum moves away from the blue wavelengths and closer to the red wavelengths, and these red wavelengths in the afternoon would tell our body to release melatonin to prepare us for bed. The problem in today is that electronic devices like cellphones, laptops, televisions and lightbulbs emit high amounts of blue light which interferes with our bodies circadian rhythm, tricking it into thinking its mid day. So when being exposed to artificial light after the sun sets, we realise cortisol instead of melatonin to prepare us for the day! This is one of the major reasons why we just don't get enough good quality deep sleep.
