![]() ![]() Should You Use Both a Wake-Up Light and a SAD Light? But when placed a foot or so from the body, and exposed for over 30 min, they seem to be quite effective at treating Seasonal Affective Disorder. These lights are in fact much dimmer than the sun. ![]() SAD lights (or Happy Lights, to use a more friendly term) are designed to blast you with daylight-simulating light for a period of time. These lights, such as the Verilux Happy Light line of SAD lamps, function very differently than a dawn simulator. The lights used to treat Seasonal Affective Disorder are often 10,000 Lux or more in power. ![]() Is a Dawn Simulator the same as a SAD Light? These apps are mostly free, and are often built-into your OS at this point. If you’re even considering purchasing a dawn-simulating light, you should absolutely be using fLux on your computer, Night Shift on your phone, or any other blue-light filtering systems available. This method doesn’t work as well, as it doesn’t actually simulate the color changes perceptible to the eye.įor this reason, none of these alarm clocks are included in this list. Instead, they have essentially a dimmer on the bulb, and that dimmer is slowly increased. There are many lower-end alarm clocks like the Mosche Clock reviewed here that advertise themselves as dawn simulating or sunrise simulating, but they don’t actually change color temperature. This is designed to mimic the way the sun’s rays actually work, and to simulate dawn and dusk as accurately as possible. In the case of dawn simulation, this means that the light will start out with a red/orange glow, and slowly morph into a daylight color cast. Color Temperature ChangesĪll of the sunrise alarm clocks in this round-up feature color temperature changing lights. With the dawn simulator, it will just turn on at the right time in order to help your sleep and wake-up process. If you are working with Light Therapy Glasses or a SAD lamp, you’ll need to actively carve out 30 minutes or more to sit in front of it to get benefits. 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. ![]()
