Human: Is it normal for a woman to experience hot flashes in her 50s? Assistant: 
Yes, it is common for women to experience hot flashes in their 50s. Hot flashes are the most common symptom of menopause and occur when estrogen levels drop dramatically. Estrogen plays an important role in regulating body temperature, so when estrogen levels decrease, it causes a sudden increase in core body temperature that can result in hot flashes.
