Stress Triggers the Sympathetic Nervous System (SNS): Anxiety activates the SNS, which prepares the body for action by releasing adrenaline.
Increased Heart Rate: Adrenaline causes the heart to beat faster, sending more oxygen and nutrients to vital organs and muscles.
Rapid Breathing: To support heightened physical demands, the lungs work harder, speeding up the breathing rate.
Blood Flow Redistribution: Blood is diverted from non-essential areas (like the digestive system) to major muscles and vital organs.
Dilated Pupils: The pupils dilate to allow more light into the eyes, improving vision in preparation for danger.
Decreased Digestion: Anxiety slows down the digestive process, which can lead to nausea or discomfort.
Mental Alertness: Anxiety sharpens focus and increases mental clarity, allowing a person to quickly assess a threat.
