Progressive alarm clocks use gradual light or sound to reduce sleep inertia, offering a gentler, more effective wake-up than abrupt alarms and supporting circadian timing.

From twin-bell bedside clocks to sunrise simulators and smart wake-ups, alarm clocks evolved into varied tools. Modern options include radio-controlled accuracy, sunrise lamps, smart speakers, wearables, and battery-backed travel models - choose based on how you wake and whether you need integration or simplicity.
