What are some of the extremes a human body can reach before collapsing down completely?

Answer 1

The human body is the example of a perfect machine. When the body is working normally, all systems are contributing to a balanced body. When the body is at balance, or at equilibrium, it is known as homeostasis. Two extremes that the human body can reach is both "hyperthermia" and "hypothermia". Hyperthermia occurs when the body enters extreme heat. When this happens, the body core temperature spikes to abnormal levels (way above 98.6). When the body becomes this hot, it begins to take in more heat than it can release. As we know, exocrine glands are activated when our body begins to overheat. In hyperthermia, the exocrine glands can not produce enough sweat to evaporate and cool the body down.

On the other hand, hypothermia is the exact opposite effect. Hypothermia occurs when the core body temperature drops to below normal levels. Extremely cold environments can cause hypothermia to set in. In this situation, the body becomes so cold that it loses heat faster than it can produce heat. The body will begin to shiver in its last attempt to produce energy in the form of heat. These are two extreme conditions that can cause the body to completely shut down, ultimately leading to death.
