AP PSYCHOLOGY

Detailed explanation-1: -We spend about one-third of our life either sleeping or attempting to do so.

Detailed explanation-2: -A good night’s sleep is vital for every human being to survive. Given that an average a person sleeps for 8 hours in a day, that means that an average person will sleep for 229, 961 hours in their lifetime or basically one third of their life.

Detailed explanation-3: -Sleeping, like breathing, is an action that we undertake throughout our entire life. We spend approximately 30% of our time sleeping [1], and this is strictly necessary since sleep is the natural state of rest and self-regulation of the organism.

Detailed explanation-4: -If the average night’s sleep is eight hours (ie one third of a day), one sleeps for one third of one’s life. If you live, say, 75 years, that’s 25 years asleep, or 9, 125 days.

Detailed explanation-5: -As shown in Figure 2, pooled mean estimates for overnight sleep duration declined from 9.68 hours (3–5 years age band) to 8.98 hours (6–8 years age band), 8.85 hours (9–11 years age band), 8.05 hours (12–14 years age band), and 7.4 hours (15–18 years age band).
