Back in middle school, I had a science teacher who said, ‘Whenever you’re feeling down, force yourself to tense the muscles around your mouth and smile. This will fool your brain into thinking you’re happy.’ Years later, science has proven her right—forming a smile actually produces endorphins.

Now, psychologists are using a similar method to improve people’s moods at work (and beyond). The prescription is simple: At the end of the day, instead of complaining about your job, write down three good things that happened and why.

The researchers worked with a group of workers and discovered that after only three weeks, participants’ stress levels were lower. They also reported bringing less work baggage home. “What most people don’t realize is that positive experiences — even small ones — provide you with valuable resources that can be used to reduce stress, including physical symptoms such as headaches or muscle tension,” says the researchers. “They make it easier for you to detach yourself from work at the end of the day.”

Would you try this experiment, or do you think these mood-improvement techniques sound too good to be true? You can read the entire article here: The Powerful Effect of Noticing Good Things at Work
