An increasing number of studies shows the connection between blue light and a disruption of the circadian rhythm through suppression of the melatonin production (here are links to some interesting studies). If the production of this so called “sleep hormone” is diminished, it seems logical that the result may be a poor sleep quality and overall health consequences.
But a new study has recently shown what a variety effects a lack of a consistent circadian rhythm can have on children. The research linked the regularity of bedtime with outcomes in school tests, children´s behavior and could even connect irregular bedtimes to obesity risk. Amazingly, it didn´t seem to matter when children went to bed, but just if it was more or less the same time every day.
This research emphasizes once more how important a healthy and natural rhythm of day and night is, and that a functioning circadian rhythm is essential for health, development and well being.
