![]() ![]() Just go to bed, which you’ll be doing anyway. Once you’ve got your dawn simulation and dusk simulation setup, you don’t usually need to do much in order to use it. When it comes to light therapy, one of the nice things about a wake-up light is that it’s a set-and-forget system. Easier to use regularly than “SAD lights”.Benefits of a Wake-Up Lightĭawn Simulating Alarm Clocks have several benefits. Blue light suppresses melatonin production, which prevents people from getting to sleep at night. This is why there has been such a push for people to stop using their screens late at night, or to use Night Shift or f.Lux apps to remove blue light from the light spectrum. The reverse takes place as you go to sleep. As the color cast becomes bluer in temperature, more melatonin is suppressed, and you wake up. This light helps set the biological clock and jumpstart circadian rhythm.Īs the sensors inside the retina detect light, melatonin is suppressed in the body, and you begin to feel more awake. During dawn, your eyes are closed and you are sleeping, but your retinas still absorb some light through the closed eyelids. How Do Dawn Simulators Work?ĭawn simulator lights emit light that mimics the sun’s rays in the early dawn. The way the color temperature changes mimics the sun, and this progression is what seems to work so well for light therapy for SAD treatments. The key to this system is the changing color cast and timing of the light simulation, as opposed to the overall brightness of the sun. How Much Light Does a Dawn Simulator Put Out?ĭawn simulators tend to work with just 100-300 lux of light, surprisingly little.
