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 jumpstarts 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. If you don't find one, don't worry, we've got also got a list of the best regular alarm clocks that can help.How Much Light Does a Dawn Simulator Put Out?ĭawn simulators tend to work with just 100-300 lux of light, surprisingly little.

So these clocks can come in handy to sync your sleep/wake patterns with the cycle of the sun, attune your body to a different time zone or daylight savings, as well as help make waking at least a bit more pleasurable.īut they may not work for everyone, says Dr. The brain then suppresses melatonin - the sleep inducing hormone - and bumps up the release of cortisol and neurotransmitters such as serotonin, norepinephrine, and histamine to stir you awake. When the light is bright enough, it can stimulate the sensors at the back of your eye to tell your brain it's time to get up, according to Yuen. They contain a light that mimics sunlight as it gradually increases in intensity until your desired wake up time. Unlike your classic alarms, these clocks are designed to help you wake up more naturally to your biological rhythm.
So instead of adding to that stress with loud, triggering bells and ringtones, some people are choosing to wake up with sunrise alarm clocks - a.k.a. "Cortisol, a stress induced hormone, helps with that process." But when we start to open our eyes, "the brain has to adapt by speeding up our heart rate and constricting blood vessels ," says Dr. When we are asleep, our blood pressure is lower, which is normal when we are lying down for hours sleeping.
