Why do I experience whole-body itching after bathing following the Start of Autumn?

Generalized pruritus (itching all over the body) is typically an allergic reaction—possibly triggered by environmental allergens, cold air, or even bath water. Avoid these potential irritants. Mild cases may be managed with appropriate antihistamines or anti-itch medications. However, if severe pruritus is accompanied by a rash, consultation with a dermatologist is recommended for proper evaluation and targeted treatment. Avoid spicy foods, “trigger foods” (e.g., seafood, lamb, bamboo shoots, mangoes), and other heat-inducing or inflammatory foods. Minimize consumption of “trigger foods” as much as possible.
