Do you suffer from insomnia? Looking to brighten up those dark winter mornings? Travel much? Re-Timer claims to be able to help people adjust their circadian rhythm by strapping a 500nm / 500 lux UV free green-blue spectrum of light at a specific angle below the eyes.
Unlike traditional light therapy devices re-timer fits directly on your face like a large pair of sunglasses. It is large enough to fit over a pair of standard glasses for those who wear them. Generally re-timer prescribes 30-60 minutes each morning of wearing the device upon waking up. They also claim to be helpful for midday energy boosts and getting to bed at a desired time.
The experimental groups showed significant melatonin suppression during light stimulation, with the blue-green LEDs producing the greatest (70%) suppression.
The blue light group showed a significant 2.53-h advance of dim light melatonin onset.
The shorter wavelengths of 470, 497, and 525 nm showed the greatest melatonin suppression – 65% to 81%.
An average advance of 2 hours and 30 minutes was achieved across the sample (n = 24).
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
