Physiological changes are triggered by the fear response. The body experiences a spike in heart rate, breathing, and muscle tension. The immune system reacts by increasing the level of serotonin in the blood. Some individuals also experience goosebumps and increased blood pressure. The fight or flight response is not a healthy response. The goal is to avoid the danger and minimize the risk of death or injury, but this response can be harmful to the body.

The brain triggers a fear response by sending signals to different parts of the body. These reactions include increased blood pressure, a faster heartbeat, and an increased blood pressure. Blood is pumped to the affected muscles for physical action, and skin sweats to cool the body. Some people experience physical sensations in the chest, legs, and hands. However, this reaction is not permanent and can only happen when the threatening stimulus is removed.
