Questions & Mysteries What is Teach's non-sleeping ability related to?

[Erkan12]

Is it related to his Haki? He trained himself by using Haki that he doesn't need sleep?

Haki is also = willpower, his willpower become so powerful that it's supersedes his physicality so he doesn't need sleep?

Similar but different version of that could be: what Kuma did when his body was destroyed but he still continued to fight due to his insane willpower.

Or related to something else like special mutant-like bloodline even though that wasn't mentioned for Xebec?

unless you take having multiple souls as something to do with haki
