Twin studies make my heart sing, so if you have a link I would be grateful!
Circulation and stress regulation are rather vague. There is more blood flowing, so suddenly your neurons are long-term better working? How is this consistent with (i) the blood-brain barrier and (ii) the general observation that cognition cannot be reliably be improved by interventions? Also, what is the evolutionary story?
The sleep quality seems anecdotally somewhat real. If you follow the links above otoh much of the research seems rather iffy.

In general, references would be appreciated.
