When we think of high blood pressure, or hypertension, we often picture the common warnings like dizziness or chest pain. However, there are other more subtle, unexpected signs that may indicate your blood pressure is elevated. High blood pressure is often called the “silent killer” because it can go unnoticed for years. Catching these subtle cues early can make all the difference in preventing long-term health issues like heart disease, kidney damage, and stroke.

Here are five unexpected signs of high blood pressure:
1. Frequent Headaches or Migraines: If you’re waking up with headaches more often than usual, it could be more than just a poor night’s sleep. High blood pressure can cause blood vessels in the brain to constrict, leading to headaches or migraines. If your headaches are persistent, especially in the morning, it may be a signal to check your blood pressure.
2. Frequent Nosebleeds: Most people think nosebleeds are harmless, but frequent or spontaneous nosebleeds can be a subtle sign of elevated blood pressure. When blood pressure is high, it puts stress on the delicate blood vessels in your nose, making them more prone to rupture. If you find yourself having more nosebleeds than usual, it might be time to investigate your blood pressure.
3. Fatigue or Brain Fog: Ever feel unusually tired or foggy-headed? High blood pressure makes your heart work harder to circulate blood, which can reduce the amount of oxygen your organs, including your brain, receive. This lack of oxygen can leave you feeling fatigued or mentally cloudy, making it difficult to concentrate.
4. Anxiety or Restlessness: Unexplained anxiety or a general feeling of restlessness could be linked to your blood pressure. When blood pressure spikes, it triggers a heightened stress response, making you feel anxious or on edge. If your anxiety seems to come out of nowhere, it may be worth checking your blood pressure as a possible cause.
5. Sudden Vision Changes: Have you ever noticed sudden blurring of vision or seeing floaters? This could be a sign of hypertensive retinopathy, a condition where high blood pressure damages the small blood vessels in the eyes. While this symptom is often overlooked, it’s a warning that your blood pressure may be putting stress on your visual system.
Waiting to get in to see your favorite provider?
Here are some ways to start working on your blood pressure in an integrative way:
- Increase Magnesium Intake. Magnesium helps to regulate blood pressure. How? by helping to relax blood vessels and improving circulation. Foods rich in magnesium, like spinach, almonds, and avocados, can naturally lower your blood pressure. If you’re not getting enough through diet alone, you can always consider a high-quality magnesium supplement.
- Practice Deep Breathing and Meditation. Stress is a major contributor to high blood pressure, and finding ways to calm your nervous system can have a profound effect. Practices like deep breathing exercises (box breathing is my favorite), yoga, and mindfulness meditation help activate the parasympathetic nervous system, which is responsible for calming the body down. Aim for at least 10 minutes of deep breathing or meditation daily to see noticeable results.

- Stay Active and Move More. Movement is medicine, especially when it comes to your heart. You don’t need to run a marathon to improve your blood pressure—small, consistent steps can make a big difference. Activities like brisk walking, cycling, or even dancing for 30 minutes a day can lower your blood pressure and improve circulation. Find something you enjoy, whether it’s pilates, hiking, or a simple walk around your neighborhood. The goal is to stay active and make movement a regular part of your daily routine.
By combining these lifestyle adjustments with your magnesium intake, you’re setting yourself up for healthier blood pressure and overall well-being! But do STILL talk to your favorite provider and make sure you don’t need more blood pressure help. You have to take care of your heart—you only have one of them.
