This is the content of the report 'IKEA Sleep Uncovered' released by global home furnishings brand IKEA on the 19th.
From August 13 to September 20 last year, IKEA surveyed 55,221 people (1,003 in Korea) in 57 countries around the world for their sleeping habits and sleep disturbances. A sleep index of 0-100 points was calculated based on a total of five items: sleep quality, sleep time, sleep time, sleep flow, and weather condition.
As a result of the analysis, Korea's sleep index was 59 points, lower than the global average (63 points), and ranked 50th out of 57 survey countries. China, which scored 74 points, ranked first in the sleep index, and Norway, which scored 56 points, ranked lowest.
South Korea, in particular, evaluates the quality of sleep low, according to the survey. Only 17% of respondents answered that their self-evaluated sleep quality was good, ranking at the bottom of the survey. Egypt ranked first, with 64% of respondents saying they have good sleep quality.
The average daily sleep time in Korea was 6 hours and 27 minutes, which was recorded as the fourth sleep-deprived country among the survey subjects. The countries with the lowest average sleep time were Japan (6 hours and 10 minutes), Israel (6 hours and 21 minutes), and the United States (6 hours and 25 minutes). China, which ranked first in average sleep time with 7 hours and 13 minutes, is the only country among the survey countries to sleep more than 7 hours.
Stress (17%), anxiety disorders (12%), too much thinking (11%), and sleep disorders (8%) were identified as the top four factors that interfere with people's sleep around the world. The top four sleep disruptors selected by Korean respondents were sleep disorders (16 percent), temperature (15 percent), stress (14 percent), and electronic devices (12 percent), which are higher than the global average (8 percent for sleep disorders and 3 percent for electronic devices).
Despite concerns that it affects the quality of sleep, it has been confirmed that cell phone use has become a pre-bed routine for many people. Seventy-two percent of respondents around the world said they use mobile phones in their bedrooms, with 86 percent of those aged 18 to 24. Forty-eight percent of Korean respondents also said they use mobile phones in their bedrooms, and the percentage of respondents aged 18 to 24 soared to 73 percent.
Respondents around the world cited regular bedtime and wake-up time (15%), tranquility and rest (13%), and comfortable beds and bedding (10%) as the top three factors conducive to a good night's sleep. Exercise (22%) was the most conducive factor for deep sleep as revealed by Korean respondents, followed by regular bedtime and wake-up time (11%), and noise reduction (6%).
Air conditioners or fans (24%), blackout curtains or blinds (21%), about (19%), music, podcasts, and audiobooks (17%) were among the top sleep aids preferred by respondents worldwide. Korea also had high preference in the order of air conditioner or fan (34%), blackout curtain or blind (22%), music, podcasts, audiobooks (15%), and about (12%). Drinking (10%) is the fifth most preferred sleep aid in South Korea, and the response rate was about twice as high as the global average (5%).
In addition, 66% of respondents worldwide and 58% of Korean respondents answered that the quality of sleep increases in neatly organized spaces, so the environment of the space also affects sleep.
According to Ikea's report, ▲ As an effective way to sleep well, ▲ Maintain a constant bedtime and wake-up time even on weekends ▲ Darken the lighting and provide comfortable bedding to create a cozy sleep environment ▲ Avoid using electronic devices before bedtime ▲ refrain from overeating or caffeine and alcohol ▲ Don't try to fall asleep by force.
