If stress is prolonged the response may be ineffective and cause damage to the body resulting in increased risks to illness. Stage three is the final stage which occurs if the stressor wasn’t effective. If the adapting resistance stage lasts longer than expected exhaustion will occur. This stage results in withdrawal of body resources and energy and can lead to long term illnesses.
