<p>Is there any clear description as to how Aang survived for 100 years inside of the iceberg?</p>

<p>Can Avatars do that? If they can, then why didn't the other Avatars stay alive for long time periods? And whatever was the case, how did Aapa stay alive too?</p>

In the Avatar universe, much like in the *Futurama*, *Frozen* or *Once Upon a Time* universes, some people who are frozen under certain conditions have their metabolisms pause.

In *A:TLA*, Aang, after freezing himself and Appa, is sustained through the Avatar State according to this [currently unsourced portion of Aang's page in Avatar Wikia](http://avatar.wikia.com/wiki/Aang):

> The Avatar State kept him alive, albeit not fully conscious, in the iceberg for about a hundred years while the war raged on.

I am guessing the Avatar State also sustains Appa.

This does not really happen in real life except for things like [Cryptobiosis](https://en.wikipedia.org/wiki/Cryptobiosis) but is seen in much fantasy and scifi.
