I had hot flashes for years. First in perimenopause, five or six a day at my worst. With consistent lifestyle changes and the right supplements, they eased up significantly. By the time I reached post-menopause they were infrequent and no longer disruptive. I treated them the way most of us do: as something to manage and move through, not as a signal worth paying closer attention to..
I was wrong about what they were.
What I have since learned is that hot flashes are not just a symptom of hormonal change. For some women, they are a signal. And that signal is about your heart.
I want to share this because I genuinely do not think most women, or most doctors, are having this conversation. And after two doctors dismissed my health concerns in post-menopause, I have zero patience for information that should be reaching us and isn't.
What the Research Actually Shows
Hot flashes were studied for a long time as a quality-of-life issue. Are they disruptive? Yes. Do they affect sleep? Absolutely. But in recent years, researchers started asking a different question: what is happening inside the body when a hot flash occurs? And what they found changed how I think about this entirely.
Women who experience frequent or severe hot flashes show measurable changes in how their arteries function. Specifically, their arteries have a reduced ability to relax and dilate properly. This is called reduced flow-mediated dilation, and it matters because healthy arteries need to be flexible and responsive. When they lose that elasticity, blood flow is affected and your cardiovascular risk goes up.
On top of that, studies have found a strong connection between hot flashes and higher levels of aortic and coronary artery calcification. Your arteries can become stiffer and less elastic. And here is the part that stopped me cold: these vascular changes can exist even in women who have no other traditional risk factors, meaning no high blood pressure, no high cholesterol, none of the usual markers. Hot flashes can be an independent signal of subclinical cardiovascular disease.
"Hot flashes are not just a nuisance. For some women, they may be telling us that the arteries are changing in a way that increases cardiovascular risk."
Night sweats carry an even higher level of concern. Nocturnal hot flashes that disrupt your sleep are particularly linked to elevated cardiovascular risk, according to The Menopause Society. So if you are lying awake at 3am kicking off the covers and then freezing five minutes later, that is not just an annoyance. It is worth paying attention to.
Why This Matters So Much in Post-Menopause
When we enter post-menopause, estrogen drops by up to 90%. Estrogen was doing a lot of quiet work in our bodies, including protecting our cardiovascular system. With that protection largely gone, heart disease becomes the number one killer of women in post-menopause. That is not a small fact to sit with.
So when hot flashes persist into post-menopause, which they do for many women, and those hot flashes are now linked to arterial changes and calcification, the picture becomes more serious than most of us were ever told.
I have Atrial Fibrillation. When I tried to talk to two different doctors about my weight and my heart health in post-menopause, I was dismissed. One told me my weight had nothing to do with my heart. I knew that wasn't right but he said it with enough certainty that I started questioning my own knowledge. I was right to question him, not myself. The connection is real and documented. And the connection between persistent hot flashes and cardiovascular risk is just as real.
The Menopause Society and Mayo Clinic both flag hot flashes as an independent cardiovascular marker, meaning these vascular changes can show up regardless of other risk factors like cholesterol or blood pressure.
If you have frequent or severe hot flashes, especially if they are persisting beyond two or three years after your last period, this is worth a specific conversation with your doctor about your heart health.
What I Want You to Do With This Information
I am not sharing this to scare you. I am sharing it because I believe you deserve to walk into your doctor's office with this knowledge in your pocket.
Most women are told that hot flashes are something to ride out. Take this supplement. Try this breathing technique. Wait it out. And yes, there are absolutely things that help reduce the frequency and intensity, and I talk about those a lot because I have lived it. But the conversation also needs to include: hot flashes are a signal worth taking seriously from a heart health perspective.
Here is what the research supports doing:
- Manage blood pressure and cholesterol proactively, even if your numbers look okay right now
- Prioritize strength training, which protects your heart and your muscle mass at the same time
- Address sleep disruption seriously, because nighttime hot flashes carry higher cardiovascular risk
- Talk to your doctor specifically about cardiovascular screening if you have frequent or persistent hot flashes
- Look into Menopause Hormone Therapy if you have not already, as current research suggests it may offer cardiovascular protection when started in the early post-menopause years
My Own Experience With Persistent Hot Flashes
I never got rid of my hot flashes completely. In perimenopause I brought them down from five or six a day to occasional and much milder. In post-menopause they are few and far between now, but they still show up, especially when I fall off my supplement routine or when my stress levels go up.
When I learned about the cardiovascular connection, it reframed everything for me. I stopped seeing my lingering hot flashes as a failure, as something I hadn't fixed yet, and started seeing them as information. My body telling me: pay attention here. Support your heart. Do not get lazy about the lifestyle habits that are protecting you.
And that is the message I want to leave you with. Hot flashes are not just uncomfortable. They are your body communicating. The question is whether we are listening.
"I stopped seeing my lingering hot flashes as a failure and started seeing them as information. My body telling me: pay attention here."
The Bigger Picture
We live a third or more of our lives in post-menopause. What we do in this phase, how we eat, how we move, how seriously we take our cardiovascular health, determines so much of how we feel and how long we feel well.
The women I talk to who think they are fine after perimenopause, who are accepting the aches and the weight and the sleep disruption as just getting older, most of them do not know that these things are connected to estrogen loss and that they can change how they feel. They do not know that their hot flashes might be worth a cardiovascular conversation.
That is exactly why I show up here. I did the research so you do not have to spend years piecing it together the way I did. You deserve to know this now, not after something happens.
Your heart health is worth advocating for. Even when your doctor doesn't lead with it.
What I Take to Support My Heart
I want to be upfront with you. The original reason I started paying serious attention to heart-supporting supplements was becauseof my AFIB. But when the research on hot flashes and cardiovascular risk started coming out, I was glad that I had already been doing something about it, even before I had the full picture.
Two supplements I take consistently and genuinely believe in for heart health:
doTERRA EO Mega+ is my omega and I am picky about this one. I tried so many different fish oils over the years and most of them either made me burp fish all day or I had no idea if they were actually doing anything. What I love about EO Mega+ is that the fish oil comes from wild-caught fish off the coast of Norway. The Nordic seas are some of the coldest and cleanest waters in the world, which means lower contamination and less exposure to heavy metals. That actually matters when you are taking something every single day. It also has Wild Orange essential oil in it, which I thought was a bit random at first until I looked into it. Turns out the Wild Orange helps protect the fish oil from oxidizing, so your body actually absorbs what you are paying for and it prevents burping up the taste. Three softgels a day with food and you are done. It is one of those supplements that works quietly in the background and you do not fully appreciate it until you run out. Which I have done. More than once.
doTERRA Turmeric Duo Capsule is my turmeric of choice. Regular turmeric has a bioavailability problem, meaning your body does not absorb much of it. This formulation is designed to actually get into your system. I take it for inflammation support and heart health. It is a non-negotiable.
If you want to know more about why I chose doTERRA specifically, and what the rest of my supplement routine looks like, I put it all together on my supplements page. The story behind why I switched matters as much as the products themselves.
