Sunrise alarm clocks reviewed for gentler wake-ups

Reviewers from The Guardian and TechRadar tried multiple sunrise alarm clocks—gadgets that wake you by gradually getting brighter before your alarm goes off, simulating a sunrise. The goal is to help you feel more alert and less groggy compared to waking with a harsh phone alarm. Devices range from simple brightening lights to advanced models offering customizable sounds and sunset features to ease you into sleep, too.
