What they are:

A hot flash is a feeling of intense body heat that can occur during the day or at night. They are a naturally occurring reaction from your body to hormonal changes, especially during perimenopause and menopause period. Depending on the cause of hot flashes, they can sometimes last for 6 to 24 months for menopause-related symptoms, or even 7 to 11 years for others. While they can be mild, moderate, or severe, hot flashes can be uncomfortable, causing discomfort or even sleep disruption.

Smoking:When smoking, your heart rate increases naturally. Other than the increased heart rate, the warmth that comes from smoking will also increase the possibility of getting heat flashes.
