Answer 1

You need oxygen and water and nutrients because those are fuel that sustains the constant chemical reaction that is your existence.

Freezing stops that chemical reaction. The human body becomes similar to a parked car. All the machinery and fuel is ready to move when you introduce the spark to start the reaction again. Heat instead of a literal spark for a frozen human.

It should work fine as soon as we find a way to freeze people without ice crystals shredding our cells apart on a massive and lethal scale.
