The quick answer is yes, the challenge is dangerous. There are plenty of videos, we won’t share them here, of people breaking bones and badly hurting themselves after falling during their attempts. There are tweets of people jokingly saying that hospitals are filling up quickly, with half COVID patients and half milk crate challenge survivors. 

While most of the challenges are attempted on grass to soften the blow, some iterations show people doing it above concrete, dirt, or other, less forgiving options, so their landings look a lot more painful. Falling from that high up while hitting the crates on the way down can lead to some pretty nasty injuries. The last thing anyone needs at this point is to deal with health issues that could have been prevented. I would be remiss if I didn’t say please don’t try this at home. One viral moment is not worth the expensive medical bills.
