Some over-the-counter treatments for hot flashes are vitamin B complex, vitamin E and ibuprofen. Natural or alternative remedies, including evening primrose, soy products, black cohosh and flaxseed, may also help to relieve hot flashes, as WebMD reports.
Avoiding stress, caffeine, alcohol, spicy foods and cigarette smoke helps lessen the frequency or severity of hot flashes. Deep, abdominal breathing and daily exercise may also help to minimize hot flashes, according to WebMD. Wearing light layers of clothing made of natural fibers, using fans, using a cool pillow and sleeping in a cool environment may help minimize the effects of hot flashes.
