The Impact of Sleepiness on Accidents

Sleepiness increases attention lapses, slows reaction time and cognitive processing, and makes the drowsy driver as dangerous as one who is impaired by alcohol. This was demonstrated by results from studies with adults who were exposed to extended periods of wakefulness and then subjected to grammatical reasoning and psycho-motor testing.

Afternoon nap-time typically coincides with a brief lag in the body’s internal alerting signal. This signal, which increases throughout the day to offset the body’s increasing drive to sleep, wanes slightly in mid-afternoon, giving sleep drive a slight edge.

Insomnia is the perception of poor-quality sleep, including the inability to fall asleep or stay asleep. Because people differ in their need for sleep, there are no fixed criteria that define insomnia. Insomnia is very common and occurs in 30% to 50% of the general population. Approximately 10% of the population may suffer from chronic (long-standing) insomnia. Sleep onset insomnia is characterized as occurring at the beginning of the desired sleep time and lasting for greater than 30 minutes. Sleep maintenance insomnia is when individuals fall asleep, but awaken periodically or for lengthy periods during the night, increasing the “wake after sleep onset.”
