Why does perimenopause cause hot flushes?

Hot Flushes is a very common presentation of Perimenopause. A flush may begin in the face, neck, or chest and spread with warmth, sweating, a fast heartbeat, or skin redness. The body may then cool quickly, leaving you chilled or unsettled.

Triggers vary. A warm room, layered clothing, alcohol, spicy food, stress, or a hot drink may make episodes more noticeable for some people. Flushes can also disturb sleep, which may contribute to daytime tiredness and irritability.

Notice patterns in a symptom diary and try practical cooling measures such as breathable layers, a fan, cool water, and a cooler bedroom. Regular movement, relaxation strategies, and a consistent sleep routine may also help some people manage triggers and recovery.

If flushes affect sleep, work, or confidence, discuss treatment with a clinician. Options may include hormone therapy or non-hormonal medicines, depending on your symptoms, health history, and personal preferences. Do not stop prescribed medicines or begin hormone treatment without individual advice.

Arrange a review if new sweating or flushing is persistent, severe, occurs with unexplained weight loss, fever, chest pain, fainting, or a racing heartbeat that does not settle. Symptoms that start after menopause or follow a new medicine also deserve assessment.

Ask whether your symptoms fit perimenopause, which triggers are worth tracking, and how hormone or non-hormonal treatment might interact with your medical history.
