The alarm stage of stress is more popularly known as the fight or flight stage stage. It is in this stage that the brain sends signals to the different parts of your body taking the message that you are in a perilous situation. Upon receiving the messages and your body started to react, you can choose between the flight and fight response. You can either fight or flee away from that dangerous place. This alarm stage of stress as explained by the father of stress, Hans Selye is commonly characterized by fast and racing heartbeats.
The heart is the primary organ, which pumps blood through the body. The heart automatically adjusts the blood flow to match the activity levels by the intake of more oxygen.
The heart functions appropriately in the presence of oxygen. During a time of activity or an exercise, the body requires an extra amount of energy to meet the needs of the activity. The heart adjusts itself by taking up more oxygen so that the blood flow is increased and the oxygen demand is met.
