At what age might men start experiencing hot flashes due to hormonal changes?

Hot flashes in men typically begin in the mid-50s and often become more frequent and intense with age. Common causes include low testosterone (andropause), prostate cancer treatments like androgen deprivation therapy, thyroid disorders, medication side effects, anxiety, and certain infections. Symptoms may include sudden warmth, sweating, flushed skin, and rapid heartbeat. Because hot flashes can signal an underlying hormonal or medical condition, men experiencing them should consult a doctor for proper evaluation.

Explanation

Hot flashes in men are not as common as in women but can happen, especially when there are changes in hormone levels. Research has looked at men aged 55, 65, and 75 years and found that some men in these age groups have experienced hot flashes. This means that many men might start noticing these symptoms around their mid-50s. The reason for these hot flashes is linked to changes in hormones, especially a decrease in testosterone. When testosterone levels change or drop, it can affect how the body regulates temperature, sometimes causing a person to suddenly feel very warm and sometimes even sweat. Similar reactions may also occur in men who are recovering from treatments that lower testosterone, like therapy for prostate cancer. If you or someone you know starts experiencing hot flashes, you can get personalized insights by taking a free symptom checker test to better understand what might be causing these symptoms, though it's always a good idea to follow up with a doctor for professional advice.
