22 Unexpected Physical Symptoms Caused by Chronic Stress

16. Flare-ups of Hives or Unexplained Rashes

That sudden itchy rash or outbreak of hives that appears from nowhere could be your skin screaming "stress!" The immune system, heavily influenced by stress hormones like cortisol, can go into overdrive, triggering inflammatory responses in the skin. This can lead to the release of histamine, causing hives (urticaria) or worsening conditions like eczema. These dermatological SOS signals are often a visible manifestation of internal turmoil. Recognizing stress as a potential trigger is key to managing these flare-ups through both skincare and dedicated stress-reduction practices.
