Mattress City wants you to know that young drivers who don’t get enough sleep are at a significant risk of having a car accident. This is according to a study published in the May 21st edition of the journal pediatrics. Sleeping less on weekends can put young drivers at greater risk of having a car crash at night, as well as having an increased risk of run-off-road crashes. Sleepiness is associated with lapses in attention, slowed reaction times, impairments in judgment, difficulty regulating emotions (including aggression) and risky behavior. These effects are magnified by alcohol consumption. The study examined the association between sleep and motor vehicle crashes in more than 20,000 newly licensed drivers ages 17 to 24 and found that 86% of young-driver deaths happen between 8pm and 6am.
