Adrenaline and Altitude Effects
When you're paragliding, the sheer thrill, combined with the physiological effects of being at a higher altitude, naturally causes your heart rate and
blood pressure to climb. The body's response to this excitement includes releasing adrenaline, which not only speeds up your heart but also constricts your blood vessels. For individuals who already experience elevated blood pressure or have a condition where it fluctuates unpredictably, this temporary surge can place significant strain on the heart. This increased pressure mid-air elevates the risks of experiencing serious health events like fainting or, in the most severe cases, a stroke. Even for those managing their hypertension with medication, ensuring their condition is stable and their doctor has given the all-clear is paramount for engaging in such adventurous activities without undue risk.
The Critical 140/90 Limit
While there isn't a universally defined medical 'clearance' for paragliding based on a single blood pressure reading, a widely accepted practical safety guideline exists. Cardiologists suggest that maintaining blood pressure readings below 140/90 mmHg is generally considered a safe threshold for recreational paragliding. For individuals who are new to paragliding or are older, it's even more advisable to aim for readings closer to 130/80 mmHg. The most important factor, however, is not just the number itself, but its stability over time. Consistent readings within these limits, rather than a one-off measurement, are key to ensuring your cardiovascular system can handle the stresses of altitude and excitement.
When to Avoid Flying
There are specific scenarios where paragliding poses a significant health risk, and it's essential to know when to refrain from flying. If your blood pressure consistently measures at 160/100 mmHg or higher, especially if it doesn't respond well to prescribed medication, it's classified as stage-2 hypertension. At this level, the risk of serious cardiac events such as a heart attack, stroke, or sudden dizzy spells is considerably heightened, and these dangers are amplified when you are in the air. Furthermore, anyone experiencing acute symptoms like chest pain, severe headaches, difficulty breathing, visual disturbances, or any tendency to faint should absolutely postpone their flying plans. A history of recent hypertensive crisis, pre-existing heart disease, stroke, or an uncontrolled irregular heartbeat are also strong reasons to avoid paragliding.
Stability Over Single Readings
It's crucial to understand that having your blood pressure under control with medication doesn't automatically qualify you for paragliding. Dr. Fernandes emphasizes that a person's fitness for such an activity hinges on consistent, stable blood pressure readings, the absence of any related health complications, and the ability to function symptom-free. You must be able to maintain blood pressure levels between 130/80 and 140/90 mmHg across multiple measurements taken over time. Beyond these numbers, you should not experience any dizziness, discomfort in your chest, shortness of breath, or light-headedness, even if it's a side effect of your medication. Prior to flying, ensuring you've had adequate rest, are properly hydrated, and have avoided alcohol is also vital. Seeking professional medical clearance to confirm your heart is capable of handling the physiological demands of altitude and adrenaline is highly recommended.
