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.
Many adults now spend more hours of the day using laptops and phones than they do asleep, a survey has revealed. People spend an average of 8 hours 21 minutes sleeping a day â but spend an average of 8 hours 41 minutes on media devices.
