Written by HealthAnswers editorial team Medically reviewed by [HealthAnswers UK doctor review panel](https://healthanswers.co.uk/our-doctors/) Reviewed 3 July 2026 ## Quick answer What could hot flushes mean? Hot flushes are sudden waves of heat, sweating and flushing, usually linked to falling oestrogen around the menopause. Keeping cool and avoiding triggers helps some people; HRT is the most effective treatment for many women. Flushes before 40, or in men, should be checked by a GP. ## Who is this page for? This page is for people in the UK who want a plain-English overview of Hot flushes, including when to seek help and what NHS care usually involves. It explains general information, not what is wrong with you personally. ## Who should skip this page? Skip this page if you need a diagnosis, a prescription, or emergency care. It cannot replace a GP, pharmacist, NHS 111 or 999. If you are in immediate danger, call 999; for urgent advice that is not life-threatening, call 111 in England, Scotland or Wales, or use your GP out-of-hours service in Northern Ireland. On this page 5 sections ## Common causes of hot flushes - Hot flushes are common in the perimenopause and menopause. - Falling oestrogen affects the brain's temperature control. - Heat, alcohol, caffeine, stress and spicy food can trigger flushes. - HRT is the most effective treatment for many women under 60. - Flushes before age 40, or in men, need medical assessment. ## What are hot flushes? Hot flushes (also called hot flashes) are sudden feelings of heat, often with sweating, a red face or neck, and sometimes a rapid heartbeat. Night-time flushes are called night sweats and can disrupt sleep. They are very common in the **perimenopause and menopause**, when oestrogen levels fall and the brain’s thermostat becomes more sensitive. ## Triggers Not every flush has a trigger, but common ones include: - Warm rooms, hot drinks or heavy bedding - Alcohol and caffeine - Spicy food - Stress and anxiety - Smoking Dressing in layers, using a fan, keeping the bedroom cool, and cutting back on alcohol or caffeine help some people. ## Treatment options **Hormone replacement therapy (HRT)** is the most effective treatment for flushes for many women. It replaces oestrogen (with progestogen if you still have a womb). A GP will discuss tablets, patches, gel or spray, and your individual risks and benefits. If HRT is not suitable or not wanted, non-hormonal options may include CBT for menopause symptoms, and certain prescription medicines. Self-help alone is enough for mild flushes; you do not have to “put up with” severe symptoms. ## Other causes to consider Flushes before 40 may mean early menopause (premature ovarian insufficiency) and need prompt assessment. Flushes can also relate to some medicines, overactive thyroid, infection, or, less often, other medical conditions. Men with flushes should mention them to their clinician, especially during prostate cancer treatment. ## When to seek help See a GP if flushes are frequent, soak clothes or bedding, wreck sleep, or affect your mood and work. Ask about HRT and alternatives. Seek urgent care for symptoms that sound like a heart attack or stroke rather than a typical brief flush — for example crushing chest pain, one-sided weakness, or sudden speech difficulty. ## ! When to get medical help for hot flushes See a GP if hot flushes disturb sleep, work or daily life, or if you want to discuss HRT or non-hormonal options. See a GP if flushes start before age 40, occur with unexplained weight loss, or affect men — these need investigation. Call **111** if you need urgent advice. Call **999** for sudden chest pain, severe breathlessness, or symptoms of stroke — do not assume these are "just a flush". ## Common questions about hot flushes How long do hot flushes last? Many women have flushes for several years around the menopause, though the pattern varies widely. Some settle within a year or two; others continue longer. Treatment can reduce how often and how intensely they occur. Is HRT safe for hot flushes? For most women under 60, or within 10 years of menopause, the benefits of HRT for flushes often outweigh the risks. Risks and benefits depend on your age, medical history and the type of HRT. A GP will assess what is right for you. What non-hormonal options help hot flushes? Options include cognitive behavioural therapy (CBT) adapted for menopause symptoms, lifestyle measures, and medicines such as certain antidepressants or other non-hormonal drugs when HRT is unsuitable. A GP can discuss current NHS options. Can men get hot flushes? Yes. Men can get flushes, especially during androgen-deprivation treatment for prostate cancer, or with other hormone changes. This should be discussed with the treating team or a GP rather than ignored. Do complementary therapies work? Evidence for many herbal products is limited, and some interact with medicines or have oestrogen-like effects that are unsuitable after certain cancers. Speak to a pharmacist or GP before trying supplements. ## Sources - [NHS — Menopause](https://www.nhs.uk/conditions/menopause/) - [NICE — Menopause: diagnosis and management (NG23)](https://www.nice.org.uk/guidance/ng23)
