ecent studies show that blue-shifted light has a great effect on our brains, our sleep, and by extension, our bodies.
Our brains use blue light to help set our circadian rhythm which regulates sleep timing.
Our modern society with TV, fluorescent lighting, and computers is causing
many people to have trouble falling asleep at night and staying awake during the day.
We don't get daily cycle clues soley from the sun anymore like our ancestors did for thousands of years.
Presented here is a simple project you can make which shines blue light into your eyes
to adjust your sleep cycle.
This example is mounted on a baseball cap, but you could also mount the circuit on glasses.
Use the Blue LED Hat during the morning to set the start of your wake cycle, then avoid exposure
to blue-shifted light in the evenings.
You may also want to try using the hat while doing activities that normally put you to sleep.
Of course, don't tempt the Sandman by experimenting with dangerous situations like driving.
Monitor your wakefulness and see if you can quantify the effectiveness.
Let me know what you discover!
