How Sunrise Alarms Work
Your body is built to wake naturally with the sunrise and feel sleepy as the sun sets. The light at both the beginning and end of the day is a warm, golden tone, unlike the midday bright, slightly blue sunlight that keeps you wide awake. A sunrise alarm clock mimics this transition from morning to bright daytime light, helping to signal your body to wake up (or fall asleep, if the clock also has a sunset option).
Each alarm below offers a sunrise routine, meaning you choose a time to wake up and then the alarm clock will start displaying a deep orange glow and transition to a bright light by the time your alarm is set for. Some offer customization, allowing you to choose how long you want that artificial sunrise to be, while others have set timers. Some also allow the reverse option with a sunset routine and can double as sound machines. Most of these plug into the wall like a classic alarm clock and stay put, though sometimes there’s a companion app or recharging capabilities (if it’s not mentioned, though, assume it doesn’t).
