How does doing exercise not make you tired? When I do a workout I can’t fight the exhaustion when 9pm hits and I’m in bed and sleep like a rock until the sun comes out.

Could be the difference between those that get a "runner's high" from exercise vs those that don't. If I'm going to have to stay awake for longer than normal (adjusting for swing shifts), I plan for my exercise to take place before the last 6-8 hours of that because it gives me such a mental and physical energy boost.

Doesn’t everyone get a runner’s high if you run long enough? It just takes 20+ mins of running and most people can’t do that.

I run fairly regularly for a lot longer than 20 minutes. I have had runner's high hit me exactly one time, and it was amazing. Never again since then. Always feel like I'm dying by the time I'm done.
