What Causes Hot Flashes in Your 30s?

Hot flashes in your 30s are commonly caused by hormonal fluctuations, particularly declining estrogen levels during perimenopause. This transitional phase can begin as early as your mid-30s, though it typically starts in the 40s. Other causes include thyroid disorders, which affect up to 20% of women in their reproductive years, medications like antidepressants or blood pressure drugs, and lifestyle factors such as stress, caffeine, or alcohol consumption. Medical conditions like premature ovarian insufficiency, affecting 1% of women under 40, can also trigger hot flashes. Additionally, certain autoimmune conditions, surgical procedures affecting the ovaries, or extreme weight changes may disrupt hormonal balance and cause these sudden temperature surges accompanied by sweating and flushing.
