What side of the bed do you sleep on?
People who get out on the left side feel like they're awake an average of six minutes earlier . . . and their mood picks up an average of 15 minutes earlier. They're also 7% less likely to have someone at work comment on how tired they look.
The survey didn't offer up any reason WHY people who wake up on the left side of the bed are happier, so it's entirely possible this is a coincidence.
But we'll offer up a theory. People who sleep on the right side of their bodies are more likely to have heartburn and acid reflux, because it opens up the path between your stomach and esophagus which can throw off your stomach acid levels.
So if you sleep on the right side of the bed, you might be more likely to sleep on your right SIDE . . . so that you're not facing into the middle. And that could cause minor stomach issues that make you sleep worse.
