Boosts alertness

Inemuri involves light, non-REM sleep that can enhance focus, memory, and energy without causing grogginess, making it ideal for busy, sleep-deprived individuals. Source: Canva

Short naps work best

Naps of 10–20 minutes are ideal for restoring alertness without disrupting night sleep. They prevent sleep inertia and offer a quick energy reset. Source: Canva

Flexibility is key

Inemuri allows flexible nap durations—from minutes to longer stretches—based on the situation and the napper’s schedule and environment. Source: Canva

Enhances mental clarity

Short inemuri naps can boost cognitive function, especially during mid-afternoon energy slumps, aligning with the body's natural rhythm. Source: Canva

Not a full sleep replacement

Inemuri offers short-term benefits but can't replace the deep sleep cycles required for full physical and mental recovery from chronic deprivation. Source: Canva

Risk of sleep disruption

Frequent daytime naps may shift circadian rhythms, delay nighttime sleep, and worsen sleep disorders if not managed properly. Source: Canva

Psychological dependence

Relying on inemuri instead of improving sleep hygiene may mask underlying problems and discourage efforts to get adequate night rest. Source: Canva
