Back to topWirecutter has been researching and testing sunrise alarm clocks since 2018. For this guide:We read scientific articles about light therapy and the relationship between light exposure, sleep, and circadian rhythms.We measured each sunrise alarm clock with a light meter in a completely dark room to assess its brightness.We slept with each model at home for at least two nights, using blackout curtains to ensure a pitch-black environment.We closely evaluated the specs of each sunrise alarm clock to determine whether theyβre actually worth the investment.If you live in a home that doesnβt get a lot of natural sunlight or need a little help in the winter as the days grow darker, a sunrise alarm clock may be a good solution to help you wake up feeling less groggy. Biologically, our physiological clocks are set to wake up with the sun. As it sets, our brains start producing melatonin for sleep in the evenings. Sunrise alarm clocks (sometimes called βdawn simulatorsβ) are designed t...
