Can Mold Cause Heart Problems? What You Need to Know

I know how scary it can feel when your heart starts acting up for no clear reason. Palpitations, strange pressure in your chest, or a racing pulse out of nowhere - it’s enough to send anyone spiraling.

What many people don’t realize (and what doctors often miss) is that mold exposure can affect way more than your lungs or skin. It can mess with your heart - yes, your actual heartbeat - and cause a range of symptoms that seem totally unrelated at first.

Let’s break it down together.

First Things First: Can Mold Affect Your Heart?

Yes - mold can absolutely impact your cardiovascular system. It doesn’t happen to everyone, but if you’ve been exposed to toxic mold for long enough, especially in a water-damaged space, it’s something to take seriously.

Here’s what we know:

• Mold releases tiny particles called mycotoxins into the air

• These can trigger inflammation in the body, including in blood vessels and the heart

• Some people with mold illness develop heart palpitations, arrhythmias, or even chest pain

• Black mold (Stachybotrys) in particular has been linked to severe systemic symptoms, including heart-related issues

Common Heart Symptoms Linked to Mold Exposure

You don’t have to check every box to be affected. Just one or two of these symptoms could be your body waving a red flag:

• Irregular heartbeat or fluttering

• Heart palpitations (feeling like your heart is skipping or pounding)

• Tightness or pressure in your chest

• Dizziness or lightheadedness

• High or low blood pressure swings

• Fatigue that feels like you ran a marathon - when you didn’t

And here’s the kicker - these symptoms often come and go. That’s one reason why they’re so hard to pin down. But once you know the root cause, everything starts to make more sense.

How Mold Can Disrupt Your Heart (In Plain English)

Let’s keep this simple.

Mold exposure can mess with your heart in a few ways:

1. Inflammation overload

Mold triggers the immune system constantly, which creates inflammation throughout the body. Chronic inflammation can affect blood vessels and make the heart work harder.

2. Nervous system chaos

Your nervous system controls your heart rate. Mold can cause your body to get stuck in “fight or flight” mode - raising your heart rate even when you’re at rest.

3. Electrolyte imbalance

Mold can deplete minerals like magnesium and potassium, which your heart needs to beat properly. Without them, you may feel jittery, anxious, or off balance.

4. Mycotoxins and the vagus nerve

The vagus nerve helps regulate your heartbeat. Mold toxins can irritate it, leading to strange rhythms or skipped beats.

What to Do If You Think Mold Is Messing With Your Heart

Don’t panic - but do pay attention. Here’s where to start:

1. Check your space

• Use a mold test kit (I recommend a general DIY test or SuperStratum’s test kit)

• Look for musty smells, water damage, or visible spots on walls, ceilings, or vents

• Mold often hides behind furniture, under sinks, and in HVAC systems

2. Check your body

• Take a free symptom quiz

• Book an EZ Scan consult to get non-invasive feedback on your heart, nervous system, and inflammation patterns

• Ask your doctor to test for mycotoxins or inflammation markers

3. Support your detox pathways

• Start with gentle detox baths (like Epsom salt or clay soaks)

• Drink water with electrolytes

• Try castor oil packs over your liver to help move toxins out

4. Use nasal sprays

Yes, really. Mold colonizes the sinuses first. Clearing them helps reduce total body load and symptoms like heart palpitations.

Try:

• Snoot Spray (deep-clearing)

• Sovereign Silver (gentle and anti-inflammatory)

• Nutribiotic GSE (great for persistent sinus issues)

Can Black Mold Cause Heart Failure?

It’s rare - but in extreme cases, yes. If someone is immunocompromised or exposed to high levels of black mold over time, it can contribute to organ stress, including the heart. More often, it’s a slow, cumulative burden rather than a single dramatic event.

Remember, mold illness is a total-body condition. Your heart doesn’t get isolated from the rest of you. If your immune system, gut, nervous system, or lungs are struggling - your heart probably is too.

What’s the Long-Term Outlook?

Here’s the good news: Once you remove the mold and support your body, your heart symptoms often calm down too.

I’ve worked with countless people who were dealing with:

• Daily heart palpitations

• Racing heart at night

• Blood pressure swings

• Constant anxiety and fear of something being “wrong”

And when they followed the Clear Mold protocol - starting with their space, supporting their detox pathways, and calming the nervous system - they started feeling steady again. Peaceful. Normal.

You can get your life back. I did, and you can too.

You’re Not Crazy, and You’re Not Alone

I know how discouraging it feels to be told “your heart is fine” when your body is clearly telling you otherwise. Mold-related heart symptoms are real, but they’re also reversible. You’re not stuck like this.

Start by listening to your body. Then take one step today - whether it’s checking your air quality, switching to a safer nasal spray, or just booking a consult to explore your next move.

You don’t have to live in fear of your own heartbeat. You just need the right tools and a little support from someone who’s walked the path before.

I’m cheering you on!
