Q: There have been numerous reports recently of older people snorkeling and being found unresponsive at beaches around Maui. Are there risks for snorkeling over 50 years old?


A: The majority of snorkeling deaths or emergencies in persons above age 50 are due to cardiac arrest, usually from a heart attack. While snorkeling may seem like a fun and relaxing activity that does not require a high level of fitness ability, in reality it can place a significantly increased workload on the heart.

Aside from the obvious physical exertion required to swim, the lungs and in turn the heart, receive a slightly decreased amount of oxygen while breathing through the snorkel tube. While snorkeling, it is easy for swimmers to become panicked either from swallowing water, not getting enough air, or simply from fear due to strong currents or waves.

Panic causes release of adrenaline, or epinephrine, which further increases heart rate and constricts blood vessels. The combination of all of these factors places a significantly increased workload upon the heart and can result in a heart attack from lack of oxygen to a certain part of the heart muscle. If the heart attack involves too much of the heart muscle, it may result in cardiac arrest and death.

While this may sound scary, people over 50 can still snorkel but should take a few extra precautions: They should visit with their primary physician or cardiologist to discuss their coronary risk factors and discuss if further testing such as an EKG and cardiac stress test is needed to identify and existing heart problems before increasing strain on the heart during snorkeling or other strenuous activities.

Staying healthy by exercising on a weakly basis, not smoking, eating a heart healthy diet, and seeing your regular doctor for cholesterol and diabetes screening are the best ways to prevent a heart attack.

Lastly, if you see somebody that appears unresponsive or struggling in the water call 911 and try to get help to remove them from the water as soon as possible and start CPR by giving them chest compressions at a rate of 80-100 compressions/minutes until emergency medical responders arrive.
