Medical Conditions and Bungee Jumping: Who Should Avoid It
Standing on the edge of the Nevis platform, 134 meters above the gorge, your adrenaline is spiking, your heart rate is maxed out, and your blood pressure is soaring. It is an intense, visceral reaction that your body is supposed to have when faced with a massive drop. But for some people, that intense physical reaction isn't just a thrill—it's a serious medical risk.
As a jump master with over 400 jumps logged globally, I've seen thousands of people face the ledge. Bungee jumping in New Zealand is statistically incredibly safe, but that safety record relies entirely on jumpers being physically fit enough to handle the stress of the drop. Not everyone should jump.
Here is the straightforward, no-BS guide to the medical conditions that disqualify you from bungee jumping, and why we take them so seriously.
Why Does Bungee Jumping Stress the Body?
Before we get into the specific conditions, you need to understand what happens to your body during a jump.
When you leap, you experience a massive adrenaline dump. Your heart rate accelerates instantly, and your blood vessels constrict, pushing your blood pressure through the roof. Then, as the cord catches you at the bottom of the arc, your body experiences significant G-forces and sudden deceleration. This combination of extreme cardiovascular stress and physical force is why we have strict medical guidelines, as outlined by organizations like the New Zealand Ministry of Health and international adventure sports bodies.
What Medical Conditions Should Prevent You from Jumping?
If you have any of the following conditions, you must consult a doctor before booking, and in most cases, you will be advised against jumping.
Why Are Heart Conditions a Hard No?
Any history of heart disease, previous heart attacks, or severe arrhythmias is generally a strict disqualifier. The sudden adrenaline surge and the immense spike in blood pressure during the freefall and rebound put an extraordinary workload on your heart muscle. If your cardiovascular system is compromised, a bungee jump could trigger a severe cardiac event. We do not take chances with your heart.
Can You Jump with High Blood Pressure?
Severe, untreated high blood pressure (hypertension) is extremely dangerous on the jump platform. Because the fear and excitement of the jump naturally elevate your blood pressure, starting from an already dangerously high baseline can risk rupturing blood vessels or triggering a stroke. If your blood pressure is medically managed and stable, you must get explicit, written clearance from your physician before we let you near the ledge.
What About Back, Neck, and Spinal Injuries?
The deceleration at the bottom of a bungee jump is smooth, but it is forceful. Your body will stretch, and your spine will experience traction and compression forces.
If you have a history of severe back injuries, spinal fusion, herniated discs, or neck trauma, bungee jumping is highly unadvisable. The forces exerted during the rebound can easily re-aggravate old injuries or cause new, severe damage to weakened spinal structures.
Why Is Epilepsy a Concern?
For individuals with epilepsy, the extreme stress, sensory overload, and sudden adrenaline spikes associated with bungee jumping can act as powerful seizure triggers. Having a seizure while suspended upside down on a bouncing cord over a river is a nightmare scenario for both the jumper and the recovery crew.
What If I Am Pregnant?
This is a universal rule across all reputable operators: if you are pregnant, you cannot bungee jump. The sudden deceleration, the forces exerted by the waist harness, and the massive spikes in maternal blood pressure pose severe risks to both the mother and the fetus. It is a non-negotiable ban.
Can I Jump with Asthma?
Asthma is generally evaluated on a case-by-case basis. If you have mild, well-controlled asthma, you can usually jump, provided you have your inhaler with you. However, the cold air (especially if you jump the Nevis in winter) and the extreme stress can trigger an attack. Always inform the jump crew.
How Do Operators Screen for Medical Conditions?
We don't just take your word for it. Every jumper is required to read and sign a detailed medical waiver before they are allowed to gear up.
Why Must You Be Honest on the Waiver?
Lying on your medical waiver because you really want to jump is the most dangerous thing you can do. The waiver isn't just legal protection for the operator; it is a critical screening tool designed to keep you alive. If you have a condition and hide it, the jump masters cannot prepare for potential emergencies, and you are putting your own life entirely at risk.
If you are unsure about a condition, the rule is simple: talk to your doctor, get a medical certificate clearing you for extreme sports, and present it to the operator.
The Takeaway
Bungee jumping is an incredible experience, but it is an extreme physical event. Respecting your body's limitations is the ultimate form of self-preservation. If you have a disqualifying medical condition, there are plenty of other incredible ways to experience New Zealand without risking your life on the platform. But if you are healthy, cleared, and ready to go, the ledge is waiting.
