Rethinking morning routine: The rise of light-based alarm clocks for gentler awakenings

The sound of an alarm clock can spoil the morning for many. Even if we substitute the traditional ticking alarm clock with, for instance, the alarm function on a phone, it might still start our day on a sour note.

An alarm clock isn't necessarily about an intrusive and unpleasant sound that abruptly interrupts our sleep and leaves us both irritable and exhausted despite a full night's rest. It's been found that wake-up light alarm clocks, which apply a completely different method, are increasingly becoming a popular bedroom accessory.

So, how do they operate? A light alarm clock acts much like a sunrise simulator - at a predetermined time, it begins to radiate a progressively intensifying light. By gently illuminating the room in this manner, it facilitates a natural awakening process. A preset gentle melody may play after some time passes. Thus, it's a much softer approach than a traditional alarm clock, making mornings much more agreeable.

Are light alarm clocks effective? This question may be particularly relevant for those who are heavy sleepers. Fortunately, there's no need to dread oversleeping. We naturally start feeling sleepier when the room darkens. This is when our body increases the production of melatonin, the sleep hormone. Conversely, when the surroundings start to brighten, melatonin levels drop, causing us to awaken.

Many light alarm clocks also possess a "sunset" feature. Their light slowly and gradually diminishes, promoting better relaxation and tranquility. Some even offer the option to play soothing music.
