interesting, too, 65 per cent of people surveyed take naps, which can help provide extra rest without disrupting nighttime sleep, dr. christian benedict, neuroscientist at uppsala university, said in the report. his advice is to avoid napping too long as it can lead to “sleep inertia,” a state of grogginess and impaired performance when you wake after the nap.
the researchers developed an ikea sleep score based on respondents’ answers to questions about five factors that make up quality sleep, including sleep duration, how long it takes to fall asleep, how often people are waking up at night, do people feel tired or refreshed upon waking and are people getting a good or poor sleep (each scored from 0 to 20) for a score out of 100.
the global average sleep score is 63 out of 100, and canada comes in with the third-worst score of 58 (alongside the u.k. and australia). there’s room for improvement. by comparison, the u.s., ireland and sweden each scored even lower at 57 and norway received a score of 56.
so, who’s sleeping best? mainland china, indonesia and egypt were top sleepers at respective scores of 74, 71 and 70. india and u.a.e. scored 68, while greece, estonia and qatar scored 66.
“a lot of the higher scoring nations, such as indonesia and india, put a lot of importance on family. social connections can often help to build community and a higher purpose that feeds into your general happiness, and that in turn can impact sleep,” dr. sophie bostock, founder of the sleep scientist, said in the report.
