London: People’s perception of their sleep quality is linked to their well-being, especially their mood the next day, finds a study.
Researchers from the University of Warwick in the UK conducted a study across a two-week period. More than 100 participants aged 18-22 years were asked to keep a daily sleep diary about the previous night’s sleep, including what time they went to bed, time they got ready to fall asleep, the amount of time it took them to fall asleep, what time they woke up, what time they got out of bed, and how satisfied they were with their sleep in general.
Five times throughout the following day, participants were asked to rate their positive and negative emotions and how satisfied they were with their life. Participants also wore an actigraph on their wrist which measures a person’s movement, for the duration of the study, to estimate their sleep patterns and rest cycles.
Researchers compared the actigraphy data with the participants’ perceptions of their sleep and how they felt throughout the following day. They wanted to find out how fluctuations from people’s usual sleep patterns and quality are related to their mood and life satisfaction the next day.
