Major publishers like Hachette have recently released adult coloring books in France. Even luxury brands like Hermès and Yves Saint Laurent have put out high-end books of intricate black-and-white designs.  Fans say coloring helps them relax and de-stress. And there’s some research to back up the practice. A 2012 study in the journal Art Therapy (where else?) found adults who colored intricate forms like Hindu mandalas enjoyed a big drop in anxiety compared to those who did not color or who colored on blank sheets of paper. “Coloring of a reasonably complex geometric pattern may induce a meditative state that benefits individuals suffering from anxiety,” the Art Therapy authors say.

People gather in theaters or presentation spaces and watch sentimental videos intended to make everyone weepy.

Some early research from Swansea University in the UK indicates ASMR may actually provide some calming benefits.  A Good Tickle You’ve heard that laughter is the best medicine. But a good tickle may also cure what ails you. A Japanese study team found tickling rats—yes, you can tickle a rat—helped the rodents overcome fear and anxiety related to past memories of electric shock.

In both Georgia and Colorado, groups have organized recreational tree climbing as a fun, therapeutic escape from adult life.  Dry Skin Brushing This one has recently gained some popularity in the U.S., though there’s still little-to-no research backing it up.
