It’s no secret that sleep significantly affects our mood and performance the next day. But how many hours of sleep is the sweet spot? Jawbone’s study offers concrete recommendations.
The company analysed the sleep and recorded moods of its hundreds of thousands of UP wearers (over 80 million nights of sleep, and 5.6 million self-reported mood entries) and found that the “right” amount of sleep for the best mood is between eight and 9.5 hours at night. Those who get that amount woke up happier than those who slept fewer or more hours.
Other interesting findings:
- When people got an extra hour of sleep compared to normal, they woke up 5 per cent happier
- Losing two hours of sleep had a bigger effect on mood than gaining two hours of sleep
Everyone’s different, of course, and we might differ in how much sleep we require. However, if you’re like the average person in this study, you might want to aim for a consistent 8-9.5 hours of sweet sleep every night.
