Hot flashes were my biggest symptom in perimenopause. At one point I was getting more than 20 a day, some of them spilling into the night as sweats that left the bed soaked through like I'd been battling flu. It was exhausting. Disruptive. Genuinely overwhelming at times.
I was working in the police at the time, which made it worse. Static uniform, stab vest, the pressure of responding to incidents — I couldn't just peel off a layer when the heat rose. It was uncomfortable to the point of being nearly unbearable, and it left me with some nasty rashes. It was one of the reasons I eventually moved from response work into an office-based role.
These days, in post-menopause, I still get the odd flash. What I've noticed is that stress seems to bring them on — a useful reminder of the importance of paying attention to, and supporting the nervous system.
What's actually happening?
Most explanations of hot flashes stop at "hormones changing." True, but it doesn't tell you much. Here's the more interesting version.
Oestrogen has a hand in regulating the hypothalamus — the part of the brain that acts as your internal thermostat. As oestrogen fluctuates and then declines, that thermostat becomes more sensitive. It narrows its comfort zone. Small shifts in temperature, stress hormones, or blood sugar that your body would once have shrugged off now register as "too hot," and it triggers a rapid cooling response: blood vessels dilate, you flush, you sweat, your heart rate climbs.
In other words, a hot flash isn't your body malfunctioning. It's your body's alarm system recalibrating to a new hormonal reality — and reacting a little too fast while it finds its new baseline. That reframe matters, because fear and panic around a flash can make the nervous system response worse, feeding the very cycle you're trying to calm.
What tends to set them off
A flash can arrive with no warning, but it's helpful to keep a journal and track any common denominators such as:
Stress and emotional overwhelm
Caffeine and alcohol
Spicy food
Poor or disrupted sleep
Warm rooms or heavy clothing
Skipping meals or a blood sugar dip
The natural hormonal swings of perimenopause itself
None of these cause hot flashes on their own. They're more like the spark near dry kindling — the thermostat was already primed to overreact.
The nature-first approach
Here's where I sit on this, and it's the philosophy behind everything I write: nature will never harm you. Herbs, food, rest, movement, breath — these work with your biology rather than overriding it. That doesn't mean every remedy suits every woman, and it doesn't mean natural is a substitute for medical care when you need it. But as a starting point, or as an ally alongside medical supervision, staying close to what's natural is never going to be a wrong decision.
Calm the nervous system first. Since stress is one of the strongest triggers, this is where I put my energy before anything else. Breathwork, slow walks, time outdoors, journaling — even five minutes done consistently can shift how reactive your system feels day to day. I dedicate a wellness slot every morning to my routine. It's non-negotiable, as it sets me up for the day. There will be a future article linked here.
Steady your blood sugar. Regular meals with enough protein, fibre, and healthy fat keep your body from lurching between hunger and crash — a state that can aggravate an already-sensitive thermostat. Long gaps between meals are worth avoiding if you notice flashes cluster when you're hungry or tired.
Eat and drink to cool, not heat. Cucumber, berries, leafy greens, watermelon, herbal teas — hydrating, unstimulating foods that don't ask your body to work harder to process them.
Consider seed cycling. This is my holy grail. It's one of the gentlest ways to support hormone balance through food, by rotating specific seeds across the phases of your cycle (and for those in perimenopause or post-menopause, aligning with the moon instead). It won't stop a hot flash mid-flush, but as a foundational practice it supports the hormonal terrain the flashes are coming from. [I've written a full guide to seed cycling here], including a tool that tracks the phases for you if you'd rather not keep it all in your head.
Look at herbal support. Sage, red clover, flaxseed, and magnesium are among the most commonly used for menopause support. If you're on medication, have a health condition, or have had breast cancer or treatment-related menopause, speak to a qualified practitioner before adding any of these in — not every remedy suits every situation, and that carefulness is part of respecting nature, not working against it.
Protect your sleep. Hot flashes and poor sleep feed each other in a loop. A calming wind-down, lighter bedding, and reducing screens before bed all give your nervous system less to fight against overnight.
When menopause arrives suddenly
For some women, menopause isn't gradual — it's triggered abruptly by cancer treatment, surgery, or chemotherapy. That's a different experience entirely, and it deserves different handling. If this is you, please work closely with a healthcare professional who understands your history before introducing herbs or supplements, some of which may not be appropriate depending on your treatment. Gentle nervous system support, food, rest, and tracking your symptoms can still have a place — but this is one area where personal medical guidance has to lead.
The shift that actually helps
Hot flashes are a very common symptom and they are not fun. When they are happening several times a day often at the most inappropriate time, interrupting sleep, affecting work, or making you feel out of control, they can have a real impact on quality of life.
The biggest change for me was understanding what a hot flash is — your body recalibrating, not breaking down. Awareness, followed by acceptance, is the key to managing the impact.
If you're in the thick of it: track what triggers yours, tend to your nervous system before anything else, and reach for what's close to nature first.
