"Even minor night-to-night fluctuations in sleep duration can have consequences in how people respond to events in their daily lives," said psychologist Nancy Sin from The University of British Columbia.

After assessing their baseline conditions, participants were asked for eight consecutive days about their sleep duration, daily stresses, and experiences of positive and negative events. .

Longer sleep makes positive events seem even better, and protects against the effects of daily stress.

"For those with chronic health conditions, we found that longer sleep - compared to one's usual sleep duration - led to better responses to positive experiences on the following day," said Sin.

As well as stress and chronic health conditions, other factors like disconnection from our natural sleep cycles, having to do shift work or multiple jobs, and loneliness can make getting the recommended amount of snooze time very difficult
