How Sleep and Fatigue Affect Your Senses

Lack of sleep dulls sight, sound, and taste sensitivity.
Fatigued brains filter information less efficiently.
Reaction times slow as sensory processing lags.
Even mild sleep loss reduces color perception accuracy.
The sense of smell weakens, muting appetite and flavor.
Drowsy drivers often misjudge distance and motion.
REM sleep restores sensory circuit performance.
Chronic fatigue can mimic sensory disorders.
Deep sleep clears sensory “noise” from neural pathways.
Rested senses perceive sharper, faster, and happier.
