Research shows that the healthiest way to wake up is along with the sun rising and the world gradually becoming lighter. And there’s the premise of a wake-up light alarm.
The gradual increase in light intensity tells your body the sun is coming up. As a result the pineal gland reduces the hormone melatonin that makes you sleepy and secretes the hormones cortisol and serotonin into your bloodstream.
These play an essential role in waking you up.
