Two experimental methods were performed to test how long and how much the human body can tolerate until death ultimately takes over. The next is how to revive the bodies. These experiments were done to gain information so that doctors can save soldiers on the Eastern front from hyperthermia. The prisoners were either submerged in freezing cold water for hours until eventually freezing to death, or strapped to stretchers naked and placed outside in the sub-zero temperatures that Auschwitz had to offer. Most victims lost consciousness or died when the body temperature dropped to 25 degrees Celsius (77 degrees Fahrenheit).

After the victims were frozen doctors used sun lamps to try to revive the bodies. One man was frozen and revived so many time he eventually died. These lamps were so hot they often burned their skin.

For this experiment water was heated to a hot temperature that was close to blistering. Then the doctors would forcefully irrigate this hot water into the frozen victim's stomach, bladder, and their intestines. All of the victims appear to have died from this testing.

In the picture above is a man who was kept alive for 15 days on gas (didn't specify which gas). This experiment was performed to see how much the human body can withstand when exposed to poisonous gas. As you can see, this gas made the skin deteriorate and the lips and gums are essentially non existent.

Many doctors would cut out the organs of their "patients" with no anesthetic. Multiple experiments were preformed using this method and most commonly performed on children. "Dr. Herta Oberheuser, in order to kill them, would inject oil and evipan into children's blood streams. While the children were still conscious, she removed their vital organs and limbs with no anesthetics. They usually had about 3-5 minutes before death would come. Herta also focused on inflicting wounds that were similar to the wounds the German soldiers got on patients. She would then rub objects such as; glass, wood, rusty nails, and sawdust into the wounds. Herta was the only female defendant at the Nuremberg Medical Trials. She received a 20 year sentence, but only served 10. After being released in the April of 1952, she became a family doctor in Stocksee, Germany. Her license was revoked in 1958."

Many doctors performed experiments to make their victims sterile/ unable to reproduce by cutting off the male sex organs and removing the female overies. More than 400,000 forced sterilizations were preformed.

These experiments consisted of breaking bones and transplants of the bone, muscle, and nerve. No anesthetic was used.
