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.
I agree with you. I regularly have strong insomnia and I have tried physical exhaustion.
It usually works for the first few days of doing it but then it's like my body (probably moreso my mind) gets used to it and it doesn't help with sleep anymore.
Arguably it feels even more unhealthy because it's like my body is fully exhausted and tired but my mind won't let me sleep so no restoration can happen.
Not physically exhausting yourself is the real issue. It's our natural state as humans. We're not meant to be staring at screens having discussions about chronic sleep deprivation on an internet forum, we're meant to be outside moving our bodies.
