The Science of Sleep. Sleep is one of the strangest things we do each day. The average adult will spend 36 percent of his or her life asleep. For one-third of our time on earth, we transition from the vibrant, thoughtful, active organisms we are during the day and power down into a quiet state of hibernation.
About 69.7 percent of warehouse and transportation workers and 52.3 percent of health-care and social assistance workers donât get enough sleep. Americans who work more than 40 hours a week are also less likely to get enough sleep per night, compared to those who work 40 or fewer hours. The report also indicates that people between the ages of 30 to 44 were most likely to be sleep deprived compared to other age groups.
