Snoozing your alarm doesn't make you sleepier, moodier or less cognitively sharp during the day than getting up straight away
Some say that snoozing your alarm makes you feel less awake during the day, but new research suggests that isn’t the caseHitting the snooze button when your alarm goes off may not leave you in a sleepier state than if you just got up straight away.and her colleagues at Stockholm University in Sweden analysed 31 people, who ordinarily snoozed at least twice a week, while they spent two nights in a sleep laboratory.
Around a week later, they returned to the lab, where they set their alarm half an hour before getting up and hit snooze every 9 to 10 minutes. Immediately upon waking, the participants were given a saliva test to measure their levels of the hormone cortisol, with higher amounts being a sign of wakefulness. They also rated their sleepiness on a scale of 1 to 9 and were tested on their cognition skills and mood, both upon waking and 40 minutes later.
In another part of the experiment, the researchers asked nearly 1500 people to complete a survey about their sleep habits, with 69 per cent reporting that they snoozed at least part of the time, mostly on work days. The snoozers, who were generally women, were on average six years younger and four times more likely to report themselves as being night owls than their non-snoozing counterparts.
