Why Sudden Alarms Ruin Your Morning (And How Light Fixes It)
How did you wake up this morning? If you are like 85% of modern adults, your brain was jolted out of deep REM sleep by a harsh acoustic siren. That sudden noise forces your nervous system into an immediate “fight-or-flight” response, spiking cortisol levels and leaving you groggy for hours.

Human biology wasn’t evolved to react to loud sirens. Naturally, our ancestors woke up to a gradual progression of morning light and rising ambient sounds. Morning Horizon brings this biological harmony to your nightstand.
