In some ways, modern life has driven us back to the Stone Age, when we lived in caves. In the 60s there were several experiments by French people who went into caves and stayed there. They all began to sleep either for extraordinarily long periods of time or extraordinarily short periods of time, and they couldn't tell the difference. They all said they had severe mood disturbances and depression, so much so that some of them had to leave long before they really had planned to.
The wavelengths that have the most powerful impact are the bluish-coloured ones. Within our eyes there are these cells that have a pigment that's sensitive to this blue light, that then signals to the body clock to tell it what time of day it is. Your systems within your body tend to desynchronise and so you tend to have a higher incidence of diabetes, obesity, cardiovascular disease.
