Your body heats, then shivers. You push off the duvet, then pull it back to your chin. If you feel cold at the very moments you were told to expect heat—if the chills, prickling skin, and goosebumps arrive without warning—this book is for you. Cold flushes and temperature chaos are a real, common, and stubbornly invisible part of the menopause transition. This calm, practical guide helps you recognise what is happening, understand the part of the brain that operates your internal thermostat, and build a personal toolkit for unpredictable waves of heat and cold. You will learn how to talk about your symptoms without embarrassment, protect your sleep, and know exactly when to bring them to a doctor. Whatever you decide about treatment, including HRT, this book never tells you what to choose; it explains what is generally understood, what the trade-offs are, and what to ask your own medical team. Your symptoms deserve to be taken seriously. Part of The Menopause Companion Library.
