Stress affects the body in numerous ways, one of which is triggering an inflammatory response. When you are stressed, your body releases chemicals like histamine, which can cause hives. Here’s how stress-induced hives occur:
- Stress Response: When under stress, the body activates the "fight or flight" response, releasing various chemicals, including cortisol and histamine.
- Histamine Release: Histamine can cause blood vessels to expand and become more permeable, leading to the characteristic swelling and redness of hives.
- Inflammation: Chronic stress can lead to prolonged inflammation, making the skin more reactive and prone to hives.
