A hot flash is the sudden feeling of warmth in the upper body, which is usually most intense over the face, neck and chest. Your skin might redden, as if you're blushing. A hot flash can also cause sweating. If you lose too much body heat, you might feel chilled afterward.

Hot flushes can cause due to eating hot food, drinking hot drinks, eating spicy food, menopause, thyroid problems or an adrenal rush from a dangerous situation.

Homeopathic medicines can reduce the levels of hot flashes to negligible amount, thereby bringing relief in symptoms that cause discomfort.
