The "Fight or Flight" response is a natural reaction that occurs when we face danger or stress. It prepares our body to either confront the threat (fight) or escape from it (flight). This response is controlled by the amygdala, a part of the brain that detects fear and triggers the release of stress hormones like adrenaline. These hormones increase our heart rate and energy levels, helping us react quickly. When we experience this response, our senses become sharper, and we may feel a rush of energy. This can be helpful in emergencies, allowing us to make quick decisions. However, if we experience this response too often, it can lead to chronic stress and health issues, affecting our overall well-being.
