The NHS suggests lightweight clothing, keeping the bedroom cool at night, and a cool shower, a fan or a cold drink.2
Knowing your triggers
Alcohol, caffeine, spicy food and stress can set some people off. A log helps you see your own pattern.2
HRT
NICE recommends offering HRT for hot flushes and night sweats, after talking through its benefits and risks.4
