year olds (54%) say they wake up between 5:00 am and 6:30 am on weekdays— compared to 45% of generation X'ers and baby boomers and 24% of generation Y'ers.
"As children develop into their teenage years, their bodies are biologically predisposed towards later bedtimes," says Amy Wolfson, PhD, an expert on adolescent sleep. "If they are required to get up before 6:30 to go to school, it's impossible for teens to get the amount of sleep they need."
Coping with sleepiness through caffeine and naps.
Americans are coping with sleepiness by drinking caffeine and taking regular naps. The average person on a weekday drinks about three 12 ounce caffeinated beverages, with little difference between age groups.
Napping is common in all age groups, but the two youngest groups reported slightly more napping during the week. More than half of generation Z'ers (53%) and generation Y'ers (52%) say they take at least one nap during the work week/school week compared to about four in ten generation X'ers (38%) and baby boomers (41%).
For the more than a quarter who say their schedules do not allow for adequate sleep, when asked to evaluate the day after getting inadequate sleep, more than eight in ten (85%) said that it affects their mood; almost three-quarters (72%) said it affects their family life or home responsibilities, and about two-thirds (68%) said it affects their social life.
For those who are employed and report not getting adequate sleep, about three quarters (74%) of those over 30 said that sleepiness affects their work. About two-thirds of adults (61%) said that their intimate or sexual relations were affected by sleepiness (13-18 year olds were not asked this question).
Sleepiness also played a factor in safe driving practices. Half of generation Y'ers (50%) say they have been drowsy driving at least once in the past month. More than a third of generation X'ers (40%) and approximately a third of generation Z'ers (30%) and baby boomers (28%) also say so. A staggering number, about one in ten, of generation X'ers (12%), generation Y'ers (12%) and generation Z'ers (8%) say they
