THE ALARM REACTION
Stress is any situation that upsets the homeostatic balance. Stressors can be physical or emotional events. The first step in the stress response is the alarm reaction, which triggers the fight-or-flight response.
THE STAGE OF RESISTANCE
After glucose stores are used up, the body needs to find and use an alternative fuel source. This is known as the stage of resistance and is characterized by the presence of the hormone cortisol. Over a prolonged period, cortisol suppresses the immune system, resulting in more infections and slower healing.
THE STAGE OF EXHAUSTION
When fat supplies in the body are used up, there are no easy fuel sources for the body and the homeostatic processes of the body become overwhelmed. This is known as the stage of exhaustion.
