Digital games may beat mindfulness apps at relieving stress, new study shows -- ScienceDaily

Participants who played the shape-fitting game ("Block! Hexa Puzzle") reported feeling more energised and less tired afterwards, while those in the mindfulness and fidget-spinner groups reported the opposite: their level of "energetic arousal" appeared to decline. In a second part of the study, participants who played a shape-fitting game after arriving home from work for five days reported feeling more relaxed by the end of the week than those who were asked to use a mindfulness app.
