When you limit yourself by time or space stress occurs
Stress is body’s way of responding to any kind of demand or threat. When a person feels threatened, the nervous system responds by releasing a flood of stress hormones, including adrenaline and cortisol, which prepares the body for emergency action. Heart pounds faster, muscles tighten, blood pressure rises, breath quickens, and senses become sharper. These physical changes increase the strength and stamina, speeds up the reaction time, and enhances our focus. This is known as the “fight or flight” or mobilization stress response and is the body’s way of protection.
When stress is within the comfort zone, it can help to stay focused, energetic, and alert. In emergency situations, stress can save our life—giving the extra strength to defend our self, for example-spurring us to slam on the brakes to avoid an accident.
But beyond comfort zone, stress stops being helpful and can start causing major damage to mind and body.
