Hot Flushes in Menopause

What’s Really Going On—And How to Ease Hot Flushes Naturally

Suddenly feeling like you’re on fire from the inside out?

Face flushed, brow sweating, heart racing, and the urge to rip off every layer of clothing—even in the middle of winter?

You’re likely having a hot flush, one of the most common and uncomfortable symptoms of menopause and of it often at the most inconvenient times, like in the middle of an executive  meeting.

They can come without warning, last a few seconds to several minutes, and leave you feeling uncomfortable, embarrassed, and even anxious. And at night, they often show up as night sweats, waking you from sleep and leaving you exhausted the next day.

The good news is that while hot flushes are linked to hormonal changes, they’re not something you just have to “put up with.” With a better understanding of what causes them and the right support, you can reduce how often they happen—and how intense they feel.

Hot flushes are one of the most common symptoms of perimenopause and menopause. But what exactly causes them? And more importantly—can you do anything about them?

What Is a Hot Flush in Menopause?

This leads to what researchers call a “narrowed thermoneutral zone”—meaning your body reacts to very small changes in temperature as though you are overheating. It triggers sweating, vasodilation (widening of blood vessels), and a heat rush—when in fact your core temperature hasn’t risen much at all.

3. Altered Neurotransmitters: Norepinephrine and Serotonin

Hormonal changes also affect levels of neurotransmitters, particularly norepinephrine and serotonin, both of which are involved in thermoregulation. Increased norepinephrine activity, in particular, is associated with more frequent and intense hot flushes.

4. Genetic and Individual Sensitivities

Not all women experience hot flushes the same way. Genetics, body composition, stress levels, and existing inflammation can all influence how strongly your body reacts to hormonal shifts.

Factors That Make Hot Flushes Worse

1.Hormonal Changes

As oestrogen levels drop, your body becomes more sensitive to temperature changes. The hypothalamus—the part of your brain that regulates body temperature—gets confused and reacts as if you’re overheating, triggering a hot flush even when you’re not actually hot.

2.Blood Sugar Swings

Sudden drops or spikes in blood sugar can trigger hot flushes. Skipping meals or eating sugary, processed foods can make this worse.

3.High Cortisol (Stress Hormone)

Stress plays a big role in many menopause symptoms. Cortisol affects oestrogen and can make flushes more intense or more frequent—especially when combined with lack of sleep.

4. Inflammation

Low-grade, chronic inflammation in the body (from poor diet, alcohol, or stress) can increase your body’s reaction to hormone shifts, including how it handles temperature regulation.

5. Gut Imbalance

The gut influences hormone regulation and detoxification. If your gut health is out of sync, it can make hot flushes harder to manage.

Other factors that make can cause or increase hot flushes:

• Caffeine
• Alcohol
• Spicy food
• Smoking
• High stress or anxiety
• Poor sleep

Each of these can either raise body temperature, increase adrenaline/norepinephrine, or make the hypothalamus more reactive.

How to Reduce Hot Flushes Naturally

You can’t stop menopause—but you can support your body and reduce the frequency and intensity of hot flushes with these evidence-based strategies:

Support Oestrogen Balance Naturally

Certain foods contain phytoestrogens, plant-based compounds that weakly mimic oestrogen in the body. These can help buffer the effects of declining hormones:

• Flaxseeds
• Lentils and chickpeas
• Soy products (ideally fermented, like tempeh or miso)

 Manage Stress and Cortisol

Chronic stress raises cortisol, which can narrow the thermoneutral zone further.

• Deep breathing, yoga, meditation or gentle movement like Tai Ci or simply taking a quiet walk can help calm the nervous system
• Prioritise rest, even short breaks during the day, to lower cortisol levels

Address Inflammation and  Gut Health

An inflamed system can worsen vasomotor symptoms. Focus on an anti-inflammatory diet rich in:

• Leafy greens, especially cruciferous ones like broccoli and cauliflower
• Oily fish (like salmon or sardines)
• Berries
• Healthy fats (avocados, nuts, seeds, olive oil)
• Fermented foods to support gut flora
• Focus on slow-release carbs (like oats and sweet potato) to avoid blood sugar spikes

Avoid Triggers and Keep Cool

• Wear lightweight, breathable layers
• Keep your bedroom cool and dark
• Use a fan or cooling pillow at night
• Limit spicy food, alcohol, caffeine, and sugar—especially in the evening
• Pay attention to what sets off a flush—then adjust
• Stay well hydrated throughout the day

Prioritise Sleep

Sleep disruption increases cortisol and norepinephrine, both of which can intensify flushes. Support deep sleep with:

• Magnesium-rich foods or supplements
• A regular bedtime routine
• Use Blue light blocker glasses when working on laptop or watching TV.
• An hour before going to be turn off the  TV, stop cell phone scrolling, and avoid bright lights before bed.

You’re Not Overreacting—Your Body Is Just Out of Sync

Hot flushes can feel intense, embarrassing, and exhausting—but they’re not forever, and they can be reduced naturally. Understanding what your body is trying to tell you is the first step.
