What are the typical hours when most sleep crashes occur?

Most sleep crashes typically occur between midnight and early morning. This timeframe aligns closely with the natural sleep cycle of many individuals, as these hours often coincide with the body’s circadian rhythms, leading to heightened sleepiness and fatigue. During the late-night and early-morning hours, the body's production of melatonin increases, signaling that it’s time for rest.

Drivers who are awake during these hours may struggle to maintain focus and alertness, making them more susceptible to drowsiness and accidents. Poor sleep patterns or insufficient rest contribute to this increased risk of sleep-related incidents, which tend to be more frequent during this period. Understanding this information can help drivers be more aware of their own alertness levels during these critical hours and take necessary precautions to avoid driving when they might be more likely to be fatigued.
