circadian rythm

Most circadian rhythms are controlled by the body/s biological “clock” called the suprachiasmatic nucleus or SCN. The SCN rests in the brain, light that reaches the photoreceptors in our retina at the back of the eye creates signals that travel along the optic nerve to the SCN.

These signals from the SCN travel to several brain regions namely the pineal gland that responds to light-induced signals by switching off the production of melatonin. Our levels of melatonin increase as the day gets darker. By using computers and devices, the bright lights can reset the SCN.

This free app will adjust the glow of your monitor or device by adjusting the tint based on the time of day. By dimming your monitor later in the evening and tinting the screen colour based on your selection to keep your circadian rhythm in check and help you get a good nights sleep.
