Physically exhausting yourself isnt a solution. Its tangential to the real issue. Its a bit like suggesting you can solve anxiety caused by trauma by drinking large amounts of alcohol everyday. No, instead we should be treating trauma. Its like putting autistic kids through rough ABA therapy, no instead we should finding accommodations and support for autistic people.

People have natural sleep rhythms. Society should conform to that, instead capitalism demands we conform to what it deems profit maximizing.
