Didn't get a great night's sleep? Just lie to yourself and pretend you had an AMAZING night's sleep. It might make a difference.
A new study found that when it comes to your mood, thinking you got a good night's sleep might matter more than actually getting a good night's sleep.
Researchers in England used Fitbit-style monitors to track people's sleep patterns. Then they compared the data to notes each person kept about how restful their sleep felt, and how moody they were the next day.
It turned out that when they thought they got a good night's sleep, they were more likely to be in a good mood. And if they thought they didn't sleep well, they were more likely to be in a bad mood that day.
