What Causes Hot Flushes?

Hot flushes, also known as hot flashes, are typically caused by hormonal fluctuations, particularly a decrease in estrogen levels, commonly experienced during menopause. These hormonal changes can disrupt the body’s ability to regulate temperature. The hypothalamus, the part of the brain responsible for controlling body temperature, becomes more sensitive to slight changes in body temperature. When it senses your body is too warm, it initiates a hot flush to cool down, resulting in the sudden feeling of heat, often accompanied by sweating and a red, flushed appearance, particularly around the face and neck.
