Research results show that 'joy of life' is lost due to lack of sleep

It has been pointed out that lack of sleep

causes various health problems, and that people who sleep for 6 hours have cognitive abilities that are as low as those who stay up all night . A new study shows that lack of sleep undermines 'the joy of life.'

Nancy Sin's research team, an assistant professor of psychology at the University of British Columbia in Canada, investigated the effect of sleep time on responses to daily events in a total of 1982 adults aged 33-84.

After investigating the subjects' basic sleep time, the research team conducted telephone interviews with the subjects for eight consecutive days. In the interview, he asked about 'sleep time the night before,' 'positive or negative events that he experienced that day,' and 'feelings received from the events.'

'People experience positive things like hugging and spending time in nature, which generally makes the day happy,' said Sin. However, an analysis of the interview results found that less than normal sleep time reduced the positive emotions received from positive events, Sin said. In addition, the decrease in positive emotions caused by negative events was exacerbated by lack of sleep.

While sleep deprivation has been shown to reduce positive emotions, longer sleep times have also been shown to increase the positive emotions received from positive events. In addition, the negative effects of stressful events have also been reduced.

The researchers also found that increased sleep time was particularly beneficial to people with chronic health problems. 'We have found that in people with chronic health problems, longer sleep times lead to a more positive response to the next day's positive events,' Sin said.

Sin and colleagues point out that there were some restrictions because the study relied on patient self-reporting through telephone interviews. However, as an initial study under everyday conditions rather than laboratory conditions, we believe that the results of this study may be useful for future research.

Science Alert, a science media outlet, points out that in developed countries, people tend to sleep less than the recommended 7-9 hours, and that the pandemic of the new coronavirus is further reducing sleep time. .. He argued that raising sleep priorities and sleeping longer would have a positive effect not only on health but also on the well-being of life.
