Regular lack of sleep deprives us of this most important skill: about the benefits of sleep

Even minor lack of sleep from night to night can affect how people react to events happening to them, says psychologist Nancy Sin from the University of British Columbia.

Sin and her colleagues found out how much time almost 2,000 adults aged 33 to 84 years who took part in the study spent on sleep. They were also asked questions about the stress they were experiencing and the events taking place in their lives.

"When people do pleasant things, like cuddling or spending time in nature, they usually feel happier that day," explained Sin, "but we found that when a person sleeps less than usual, they don't experience so many positive emotions when engaged in pleasant activities.

Fortunately, this effect is unstable and with an increase in the duration of sleep in a person, everything goes away. Longer sleep makes positive events seem even better and protects a person from the effects of daily stress.

At the same time, the researchers did not find a link between sleep duration and negative reactions. This suggests that sleep is especially important for positivity, the scientists note in their article, and that it is important to take into account both positive and negative effects when studying sleep.

But it should be noted that this study is based solely on the feedback of respondents, which means that its results may be inaccurate. Nevertheless, this is one of the first studies in which the effects of sleep are studied in natural rather than laboratory conditions.

Obviously, it is impossible to save on sleep. But that's easier said than done. A recent study has shown how stress is interconnected with our ability to fall asleep — both physiological processes use the same neural network. Therefore, it is not surprising that the collective stress that we experience, including due to the pandemic, affects sleep.
