Think about the last time someone you know got a high blood pressure reading. Chances are, the conversation that followed went straight to medication. Maybe a new prescription, maybe an adjustment to an existing one. What almost certainly did not happen was a real conversation about why the number was elevated in the first place.
Joel Polley, RN, has spent the better part of his career watching exactly that pattern play out — in emergency rooms, in cardiac units, in telemetry floors, and in the lives of the clients he now coaches as a naturopathic practitioner and founder of BPQuiz.com. With 20 years of experience in ICU and emergency medicine, Polley left full-time clinical nursing to do the one thing the healthcare system rarely has time to do: find the cause.
The Flooded Basement Problem
Polley has a way of explaining root cause medicine that is hard to forget. “You have a pipe that’s leaking in your basement,” he says, “and you take a mop down there to clean up all the water. What happens if you don’t fix the pipe first? You’re just mopping endlessly.” That, he argues, is precisely what happens when chronic illness is treated symptom by symptom, prescription by prescription.
When a patient receives medication to lower a blood pressure reading but the underlying driver of that reading is never investigated, the body does not stop communicating. It finds other ways to send the signal. The prescription masks one symptom; another appears. A second prescription is added. Before long, the medicine cabinet is full and the person still does not feel well.
Polley points out something that rarely gets said plainly in a doctor’s office: the word “prescription” is itself a clue. “If you took something that cured you, you wouldn’t have to keep going back to take it,” he says. A prescription, by definition, manages. It does not resolve. That distinction matters enormously when the goal is actually getting better rather than just tolerating a diagnosis.
The Blood Pressure Triangle
After years of working with hundreds of clients, Polley developed a framework he calls the Blood Pressure Triangle. The three corners of the triangle represent the three primary root causes he has identified in the vast majority of high blood pressure cases: stress, blood sugar, and lifestyle habits.
Stress sits at the top, and Polley is careful to define it more broadly than most people expect. “It’s not just my job stressing me out or my kids are stressing me out,” he explains. “It’s also past trauma. It’s unresolved grief. It’s anger issues. Those are all stressors on the body that the brain interprets as the need for fight or flight.” When the brain perceives a threat, cortisol floods the system. The heart rate increases. Blood vessels constrict. Blood pressure rises. And unlike the kind of acute stress that resolves when the danger passes, chronic emotional stress keeps that physiological response running in the background indefinitely.
The second corner of the triangle is blood sugar. People with diabetes or prediabetes frequently also have high blood pressure, and the connection is direct: excess sugar affects kidney function, alters fluid and sodium balance, and drives up vascular pressure. The third corner covers the daily lifestyle habits that accumulate quietly over years, things like processed food intake, caffeine consumption, dehydration, and poor sleep, each of which puts its own steady pressure on the cardiovascular system.
Polley also addresses three beliefs he hears constantly from clients that he says simply are not accurate. The first is that high blood pressure is genetic. “There are genetic propensities,” he acknowledges, “but if it was a gene, you would have had high blood pressure at five years old, ten years old, but you didn’t.” The second is that it is permanent. The third is that it has to dominate daily life. None of these, he says, are necessarily true once the root cause is identified and addressed.
What Hormones Have to Do With It
The connection between hormones and blood pressure is one of the most consistently misunderstood aspects of cardiovascular health, and it is the one Joel Polley returns to most often when working with women in midlife.
Estrogen, it turns out, acts as a buffer against cortisol. When estrogen levels are adequate, the body has a natural mechanism for dampening the stress response. As estrogen production drops during perimenopause and menopause, that buffer disappears. “What stressed you out at the age of 20 now feels like it’s doubly stressful at the age of 40 or 50,” Polley explains. “That’s just the lack of estrogen you used to have.” The result is that the same emotional or environmental pressures that were manageable for decades can suddenly begin pushing blood pressure numbers upward in ways that feel inexplicable.
Cortisol also plays a direct role in weight gain, particularly around the midsection, and in cardiovascular strain. Polley describes the hormonal cascade of fight or flight as designed for survival, not for the sustained, low-grade chronic stress of modern life. “That hormonal shift is supposed to reset and go back to zero,” he says. “But when we hold on to stress, unresolved trauma, unresolved past issues with people, that is an ongoing fight-or-flight, foot-to-the-gas-pedal situation in our body. And the first place you see it is the blood pressure.”
He also points to environmental exposures that many people overlook. Synthetic fibers in clothing and plastics in food containers, water bottles, and personal care products all have a documented negative effect on estrogen levels. The body cannot process or eliminate many of these compounds efficiently, and over time they accumulate and interfere with hormonal balance.
When the Labs Look Fine But You Don’t Feel Right
One of the most frustrating experiences people describe is going to a doctor because something feels genuinely wrong, only to be told that all their numbers look normal. Polley does not dismiss this experience. He has seen it from both sides of the exam table.
“There are things that we feel within us that don’t show up on labs, or they may show up on labs a year later,” he says. “Labs are not infallible either.” The healthcare system is built around data, around numbers that can be measured and compared to reference ranges. But some of the most erosive forces on the body, past trauma, chronic unforgiveness, low-grade anxiety, persistent worry, do not produce a number that shows up on a standard panel.
“Past trauma, unforgiveness, anger, worry, anxiety. Some of those things are just like this low hum that does erode your body, but doesn’t show up on a lab.”

Polley encourages people to pay attention to three body systems as early indicators that something is shifting before it becomes a clinical problem. The first is the gut. Bowel function, he says, is one of the clearest windows into overall systemic health, because the heart, the mind, and the gut are all neurologically and hormonally connected. A change in digestion is worth taking seriously. The second is sleep. Insomnia is not just uncomfortable; it is a significant driver of high blood pressure, hormonal disruption, and over time, memory decline. The third is skin. Most skin conditions, Polley notes, trace back to gut health, and a sudden change in skin behavior is the body asking a question worth answering.
The Daily Habits That Matter More Than People Think
Polley is consistent about one thing: the steps that make the biggest difference in blood pressure and overall health are rarely dramatic. They are the unglamorous, easy-to-ignore decisions made dozens of times a day.
Hydration tops his list. He references the book “The Body’s Many Cries for Water” and its documentation of how many different conditions trace back to chronic dehydration. The recommendation is simple: drink half your body weight in ounces daily, up to a gallon. He also addresses a common sleep mistake: people who stop drinking water in the evening to avoid waking up at night are actually making the problem worse. The body interprets dehydration as a distress signal and wakes up more frequently, not less. Drinking adequate water before bed helps the bladder acclimate and supports more continuous sleep.
Caffeine is another factor that deserves more honest attention than it typically gets. Polley spent nine years as a night nurse and relied on caffeine heavily, so he speaks from experience when he says that what coffee does to the adrenal system, cortisol levels, and blood pressure is well documented and worth examining if blood pressure is a concern.
Processed food is on the list as well. He notes that the World Health Organization has classified processed meats in the 1A carcinogen category. His approach is not to demand perfection but to encourage a practical 80-20 rule: 80 percent whole, clean food and 20 percent flexibility. Reading ingredient labels, even without fully understanding every word, is a starting point that builds awareness over time.
And then there is stress, the corner of the triangle that ties everything together. Polley suggests a simple reframe for people who struggle to identify what is stressing them. Instead of asking what is stressful, ask what is not peaceful. What relationships, what memories, what unresolved situations still feel unsettled? Once something surfaces, he points to a practical tool grounded in neuroscience: the brain cannot focus on two things simultaneously. Redirect attention to gratitude, specific and concrete, and that competing focus begins to dissolve the cortisol response. “As you spend time meditating on gratitude,” Polley explains, “those things start to unravel that knot of stress.”
Trust What You Feel
The body communicates continuously. It does not wait for a lab result to flag a problem. It sends signals through energy levels, gut function, skin changes, sleep quality, blood pressure readings, and the quiet, persistent sense that something is not right. Joel Polley’s central message is that those signals deserve to be taken seriously, investigated rather than suppressed, and traced back to their source.
“If you don’t feel right, trust that,” he says. “No one else may understand that. Labs may not show it. People may not see it. But trust your feeling that something’s just not right and I need to assess it, fix it, find the cause, do something about it today.”
That instinct, Polley argues, is not hypochondria. It is intelligence. The body is not making things up. It is communicating in the only language it has. The questions to ask, he suggests, are straightforward: What is my biggest problem right now? Why do I have it, and when did it start? What is one thing I can do today, without spending money, to start addressing that why? The answers to those three questions, Polley says, will almost always point toward something in diet, hydration, or sleep that can be adjusted immediately.
Joel Polley, RN, has spent 20 years watching what happens when the cause goes unaddressed long enough. His work now is built around making sure fewer people find out that way.
