Q. Hot water works for itches! I used the hottest water I could stand for a few seconds on my mosquito bites. It gave much more relief than scratching and lasted for hours. Why isn’t this technique common knowledge?
A. We have been writing about hot water (hot enough to hurt but not so hot as to burn) for itchy bug bites for 36 years. We first learned about this remedy from a 1961 edition of the textbook, Dermatology: Diagnosis and Treatment. Perhaps it is no longer mentioned in medical school, since dermatologists now have potent corticosteroid creams to ease itching.
Hot water can also be helpful in easing the itch from poison oak or poison ivy. It should never be used for hives, however, as it can make them worse.
