Can humans survive very extreme condition

Research and theorising

There's a lot of different cells in the human body could they all for example get through
extreme high temperatures above 50-60 degrees celcius for several days.
Or through extreme cold temperatures below -19 for several days without clothing (and normal hair growth).

Even better temperatures above 100-200 degrees celcius for several days.

Human extremophile cells.
For example:
-Thermo
-Hyperthermo
-Cryo, psychro

For thermophilic: Endogenous enzymes which function at high temperatures.

For cryo, psychro: Organs protected by antifreeze proteine. Biological antifreeze.
                   Very important: Endogenous (self produced) antifreeze protein.

Cryo, psychro extra: 1 Being able to partially freeze and thaw and live on.
                                  2 Being able to freeze and thaw and live on.
                                  Endogenous (self produced): Cryoprotectants, or solutes
                                  -Which lower the freezing temperature.
                                    Protects the cells and limits the amount of ice which can form inside the body.

And: Polyextremo humans

Extra: High radiation resistance

Finding out how to cause and get extremophile cells and extremophile proteins and or enzymes.

Studying single celled and multicellular extremophiles.

Research:
1 Eating eadible single celled and multicellular extremophiles.
2 Getting through the conditions of those eaten
  Building up resistance

Theorising, researching if human cells can become extromophilic or just survive those conditions.
