Ahdistusvaste

Ahdistusvaste refers to the physiological and psychological reactions of an organism when faced with a perceived threat or stressor. This response is a complex, automatic process designed to prepare the body for action, often described as the "fight-or-flight" response. When an individual encounters a situation they interpret as dangerous or overwhelming, their nervous system becomes activated. This activation triggers a cascade of hormonal and physiological changes.

Key physical manifestations can include an increased heart rate, faster breathing, muscle tension, and a heightened state of alertness. The body diverts blood flow to essential muscles, preparing for physical exertion. Psychologically, individuals may experience feelings of anxiety, fear, or panic. The intensity and duration of the ahdistusvaste can vary greatly depending on the nature of the stressor and individual differences.

While this response is a crucial survival mechanism, persistent or excessive activation of the ahdistusvaste can contribute to various health issues, including chronic stress, anxiety disorders, and other mental and physical health problems. Understanding the ahdistusvaste is important in fields like psychology, medicine, and stress management.
