The world isn’t feeling so hot — emotionally, that is.

A new survey of people’s daily emotions found that, worldwide, reports of negative emotions — including sadness, worry and stress — have increased over the last decade, reaching a record high in 2017.

For the survey, researchers interviewed more than 154,000 people in 147 countries throughout 2017.

Participants were asked whether they had certain positive or negative emotions or experiences the day before. For example, for positive experiences, they were asked whether they felt well rested, were treated with respect, smiled or laughed a lot or enjoyed themselves the day before. For negative experiences, they were asked whether they felt worry, sadness, stress, anger or physical pain on the previous day.
