A systematic review by Irwin et al. (2020) provided an in-depth analysis of how sleep deprivation contributes to traffic accidents. The review consolidated findings from multiple studies, concluding that drivers who slept less than five hours each night faced double the risk of being involved in a car accident compared to well-rested drivers. Microsleeps—brief, involuntary episodes of sleep occurring during wakeful activities—were identified as a significant risk factor. Sleep-deprived drivers also demonstrated impaired decision-making, slower reaction times, and diminished attention spans, all of which are critical for safe driving. The review further noted that nighttime drivers or those with irregular work schedules, such as shift workers, were at a heightened risk due to disrupted circadian rhythms.

This article highlights the pervasive impact of sleep deprivation beyond occupational or athletic contexts, extending to everyday activities like driving. It underscores the importance of public health campaigns to promote sleep awareness and enforce policies such as mandatory rest periods for commercial drivers. Moreover, it calls for technological innovations like in-vehicle fatigue monitoring systems to alert drivers before accidents occur. The findings make a strong case for addressing sleep deprivation as a public safety issue and emphasize the collective responsibility of policymakers, employers, and individuals to mitigate risks associated with insufficient sleep.
