How Light Wakes You Up
Light enters the body through closed eyelids and sends signals down light-specific nerve tracks to the brain. The light travels to the suprachiasmatic nucleus — a special area where the light stimulates the wake cycle with proteins and chemicals. This same area produces the sleep cycle. Dr. Hurst also noted that many mammals are tuned into the sun as their cue to wake and rest for the day.
The area in the brain that processes sound — the auditory cortex — is completely different. It focuses on communication, not wakefulness. As such, noisy alarm clocks are not naturally designed to wake you up rested.
What LightAwake Does
In mammals, visible light is the official stimulus of the sleep/wake center in the brain. Light flashes provide a more natural, effective way to wake up. Controlling certain light qualities creates more effective stimulus of the wake cycle, such as:
The LightAwake app allows users to control these variables to find the best way to wake up.
By providing user-controlled light flashes as an alarm clock, LightAwake offers an effective new way to stimulate you to a more alert, wakeful state using your iPad, iPad mini and iPhone. You can use it at home or on trips as a travel alarm. In addition to being completely portable, this silent alarm is less likely to disturb others when propped directly by your side of the bed.
Start your day the right way!
