Why Hot Flushes Happen (And How to Calm Them Quickly)
A sudden wave of heat spreads across your chest, neck or face. Your skin feels hot, your heart may beat faster, and before you know it, you're reaching for a fan or peeling off a layer of clothing.
Hot flushes can be uncomfortable at the best of times. When they interrupt an important meeting, wake you repeatedly during the night or leave you feeling exhausted the next day, they can become much more than a minor inconvenience.
Hot flushes and night sweats are common symptoms during perimenopause and menopause. They're associated with changes in the body's temperature regulation, which can make you feel intensely hot even when the surrounding temperature hasn't changed.
The good news is that there are ways to manage them. Some practical adjustments may help you cope with individual episodes, while other approaches and medical treatments can help reduce the frequency or impact of symptoms over time.
Let's look at why hot flushes happen, what may help, and when it's worth discussing treatment with your doctor.
Why Do Hot Flushes Happen During Menopause?
Hot flushes, sometimes called hot flashes, are part of a group of symptoms known as vasomotor symptoms. Night sweats are essentially hot flushes that occur during sleep.
They are commonly associated with the hormonal changes of perimenopause and menopause.
Your body's temperature regulation becomes more sensitive
Your brain contains a temperature-regulating area called the hypothalamus. It helps keep your body temperature within a comfortable range.
Oestrogen interacts with the systems involved in temperature regulation. During the menopausal transition, changing oestrogen levels can affect how these systems respond.
The result is that your body may trigger a cooling response when there's no obvious need to cool down.
Blood vessels near the skin widen, increasing blood flow to the surface, and you may begin to sweat. You can experience a sudden sensation of intense heat, flushing and perspiration.
Some women also notice a faster heartbeat or a brief feeling of anxiety during an episode.
Although hot flushes are often described as an internal thermostat being broken, it's more accurate to think of the temperature-regulation system as becoming more sensitive.
Why do hot flushes happen at night?
Night sweats can be particularly disruptive because they interrupt sleep.
You might wake feeling hot and damp, need to change your nightclothes or bedding, or find yourself lying awake long after the flush has passed.
Repeated awakenings can leave you tired, irritable and less able to concentrate the following day.
This can create a difficult cycle: poor sleep makes everything feel harder, while worrying about another night of interrupted sleep can add to your stress.
If sleep disruption is becoming a problem in its own right, read my guide to the relationship between menopause, stress and sleep.
Hot flushes are one of the most recognisable menopause symptoms, but they rarely occur in isolation. Explore the full guide to menopause symptoms to understand the wider range of changes you may experience.
What Can Make Hot Flushes Worse?
Hot flushes are influenced by hormonal changes, and you can't necessarily eliminate them by changing your lifestyle.
However, some factors may trigger or intensify episodes for some people.
Common triggers to look out for
These may include:
Alcohol: You may notice more flushing or disrupted sleep after drinking.
Caffeine: Coffee, tea and other caffeinated drinks affect people differently.
Spicy foods: Some people notice that spicy meals trigger a flush.
Hot drinks: The temperature of the drink itself may contribute.
Warm environments: Heated rooms, heavy bedding or being overdressed can make an episode harder to tolerate.
Stress and anxiety: Feeling tense or under pressure may make symptoms more difficult to manage.
Smoking: Smoking is associated with poorer health outcomes and may be associated with more troublesome menopausal symptoms.
Not everyone has the same triggers. You don't need to eliminate coffee, spicy food or every enjoyable part of your routine just because you have hot flushes.
Instead, look for patterns.
If you suspect a particular food, drink or situation is contributing, make a note of what happened and whether the pattern repeats. Change one thing at a time where practical, so you can judge whether the adjustment makes a difference.
Weight management may also be relevant for some women. Research suggests that weight and vasomotor symptoms can be related, and some interventions may help reduce symptoms in certain circumstances. This doesn't mean that weight causes every hot flush or that weight loss is the answer for everyone.
The aim is to identify what is useful for you without turning symptom management into another source of pressure.
Three Practical Ways to Manage Hot Flushes
There isn't one lifestyle technique that reliably stops every hot flush. These approaches may help you manage episodes or reduce their impact, although the results vary from person to person.
1. Make it easier to cool down
When a flush starts, your immediate priority may simply be to feel more comfortable.
Try:
Wearing layers that you can remove easily.
Keeping a fan nearby or improving airflow in your usual workspace.
Keeping cool water within reach.
Choosing lighter bedding if you regularly wake feeling overheated.
Wearing breathable nightclothes.
Keeping a change of clothing available if night sweats are particularly heavy.
If you know that certain environments make symptoms harder to tolerate, plan around them where possible.
For example, you might choose a seat near a window or air vent in a meeting room, take a cool drink with you, or avoid wearing a heavy jacket when you expect to be in a warm space for a long time.
These measures won't necessarily prevent a flush, but they can make it easier to cope when one occurs.
2. Experiment with slow, comfortable breathing
Some women find that slow, controlled breathing or relaxation techniques help them manage the distress associated with hot flushes.
You could try the following when you notice yourself becoming tense:
Sit or stand somewhere comfortable, if possible.
Relax your shoulders and jaw.
Breathe gently and slowly, without forcing a deep breath.
Allow your breathing to return to its natural rhythm.
Continue for a few minutes if it feels comfortable.
You can also practise slow breathing at a quiet point in the day so that it feels familiar when you're under pressure.
It's important to keep expectations realistic. Research has not consistently shown that paced breathing alone reduces the frequency of hot flushes. Treat it as a possible coping strategy rather than a guaranteed way to stop an episode.
Cognitive behavioural therapy (CBT) has better evidence for helping some women manage the impact of hot flushes and night sweats. It may help reduce distress, improve coping and address the sleep difficulties associated with symptoms, even when the flushes themselves continue.
Clinical hypnosis is another approach that has evidence supporting its use for some women.
These techniques don't mean that hot flushes are caused by your thoughts or that you should be able to control them through willpower. They offer ways to manage the experience and its impact.
3. Discuss treatment options with your doctor
If hot flushes are frequent, severe or affecting your sleep, work or quality of life, you don't have to rely on lifestyle changes alone.
Several treatment options may be appropriate, depending on your symptoms, health history and preferences.
Menopause hormone therapy (MHT/HRT) is an effective treatment for many people experiencing bothersome menopausal hot flushes and night sweats. Whether it's suitable for you depends on your individual circumstances and the potential benefits and risks.
If you can't take HRT, don't want to take it, or would prefer to explore alternatives, ask your GP/doctor about non-hormonal options.
Depending on your circumstances and what is available, these may include:
Certain prescription medicines that can reduce vasomotor symptoms.
Menopause-specific CBT.
Other evidence-based approaches recommended by your clinician.
Some prescription medicines originally developed for other conditions can also be used to manage hot flushes. Their suitability, possible side effects and availability vary, so don't start or change medication without medical guidance.
As a menopause health coach, I can help you explore practical lifestyle changes, understand your priorities and build habits that fit your life. I can't diagnose the cause of symptoms or prescribe treatment, and coaching should complement rather than replace appropriate medical care.
You don't need to wait until symptoms become unbearable before asking for help.
Managing Hot Flushes at Work
Hot flushes can be especially uncomfortable in professional situations.
You might feel a sudden wave of heat while giving a presentation, speaking to a client or sitting in a meeting. The physical symptoms can be difficult enough without worrying about whether other people have noticed.
A few practical adjustments may help:
Wear layers that can be removed discreetly.
Keep cool water nearby.
Choose a seat with access to airflow where possible.
Take a short break if you need one.
Identify whether particular rooms, activities or situations seem to trigger symptoms.
Consider whether changes to meeting arrangements or the working environment would make things easier.
If symptoms are affecting your ability to work comfortably, you may also want to discuss workplace support or reasonable adjustments with your employer.
You don't have to explain every detail of your medical history to begin a conversation about practical support.

When Should You Seek Medical Advice?
Hot flushes are common during perimenopause and menopause, but it's important not to assume that every episode of flushing or sweating is hormonal.
Speak to your doctor if:
Symptoms are new, persistent or particularly troublesome.
Night sweats are repeatedly disrupting your sleep.
Sweating occurs alongside other unexplained symptoms.
You're unsure whether your symptoms are related to menopause.
You want to explore treatment options.
Seek urgent medical help if flushing or sweating occurs alongside concerning symptoms such as chest pain, severe breathlessness, fainting or sudden neurological symptoms.
Your doctor can help assess possible causes and discuss the most appropriate next steps.
You Don't Have to Keep Guessing What Might Help
When hot flushes keep happening, it can feel as though you're constantly adjusting your routine in the hope that something will finally work.
You change what you eat. You try to sleep better. You avoid a drink or a particular food. Sometimes you notice an improvement, but the symptoms return unexpectedly.
That doesn't mean you're doing something wrong.
Hot flushes can be influenced by several factors, and lifestyle adjustments don't always address the underlying problem. The most useful next step is to work out which changes are worthwhile for you and whether you would benefit from additional support.
Start with manageable adjustments, notice your patterns and seek medical advice if symptoms are affecting your quality of life.
You don't have to try every possible remedy at once.
