[Question] What are some good ways to heighten my emotions?

I’ve noticed when I don’t get enough sleep, the emotions I feel the next day are higher variance—I’m a sadder sad person and a happier happy person.

I want more of this, since I prefer feeling emotions to not feeling emotions and generally enjoy higher variance in life due to novelty and stuff. What are some ways I can get this without being sleep deprived?

(Also would appreciate pushback! Think this may be wrong due to similar reasons to variance being bad in finance.)
