vasomotor symptoms

Vasomotor symptoms refer to sudden sensations like hot flashes and night sweats that occur when the body's blood vessels respond abnormally, often due to hormonal changes during menopause. These episodes happen because the brain's temperature regulation system becomes less stable, causing blood vessels to widen quickly and release heat, leading to feelings of intense warmth, sweating, and sometimes chills. They can vary in frequency and intensity and are common during menopause but may also occur in other conditions affecting hormone levels. These symptoms can impact comfort and sleep but often improve over time.
