A majority of women experience vasomotor symptoms (VMS) in the years leading up to menopause (also known as perimenopause). Vasomotor symptoms are more universally known as hot flashes (or hot flushes) and night sweats.

SWAN researchers found that African American women had the highest prevalence of VMS. Asian women had the lowest VMS prevalence.
Treatment for VMS depends on the severity of your symptoms. You may be able to manage symptoms with lifestyle changes, like avoiding triggers and keeping your bedroom cool at night.
