Hot flashes are short, sudden episodes of the feeling of intense heat of the head, neck, and chest. When a hot flash occurs with a red face, neck, and/or chest it is called a hot flush. Hot flashes typically follow a consistent pattern that is unique to the person. Some women experience sweating and/or palpitations during these episodes. Hot flashes can occur at any time, day or night, without warning. They usually last 3-5 minutes, but the duration can vary from 30 seconds to 30 minutes. Some women can have hot flashes up to twenty times a day or more. Hot flashes can greatly impact a woman’s quality of life–causing discomfort, disturbing sleep, and leading to embarrassment in social situations.
