Fun Fact
A typical human sleep cycle lasts approximately 90 minutes, progressing through light sleep, deep sleep, and REM stages. Setting a 45-minute alarm lets you wake up roughly halfway through a complete cycle, typically during lighter sleep stages. This timing can make awakening easier compared to waking from deep sleep, which often causes grogginess. Sleep researchers note that 45-minute naps, while longer than the optimal power nap, can provide both light sleep benefits and some slow-wave sleep, potentially improving procedural memory and creativity.
