What are hot flashes?

Hot flashes are a sensation of the body suddenly feeling hot. They typically begin with an uneasy feeling, then feeling intensely hot in the face and/or upper body, then feeling hot all over. Before or during a hot flash, you may feel nausea, anxiety, rapid heartbeat, dizziness, and/or headache. You may experience flushing and sweating. They can be a distressing symptom and affect your quality of life, particularly when they interrupt sleep frequently.

Hot flashes are also called hot flushes or vasomotor symptoms. They may be called night sweats if they happen at night.

What can contribute to hot flashes?

Hot flashes are usually caused by hormone changes. They are common among people with cancer and may be side effects of cancer or treatment including surgery, radiation therapy, and some medications.1National Cancer Institute. Hot Flashes and Night Sweats (PDQ®)–Patient Version. July 29, 2021. Viewed April 9, 2023. They are more common in women but also occur in men with locally advanced or metastatic prostate cancer after medical or surgical removal of one or both testicles (orchiectomy).2Charig CR, Rundle JS. Flushing. Long-term side effect of orchiectomy in treatment of prostatic carcinoma. Urology. 1989 Mar;33(3):175-8.
