While studying the effectiveness of numerous treatments for menopause symptoms like hot flashes, researchers have discovered some interesting results. Nutritional supplements containing soy isoflavones are effective for hot flash treatment. Isoflavones are a type of phytoestrogens, a plant component that has an estrogen-like effect on the body.

But, dietary flaxseed and soy flour are not effective. Another way to reduce the severity of nigh sweats  is acupuncture. A research says that mindfulness based stress reduction decreased the severity of hot flashes by 40% in women in an 11 week period of study.
