What’s the one app you hope you never have to use, but could literally save your life? For the Coen family, that answer became crystal clear during a routine summer run that nearly ended in tragedy. Will Coen, a fit 15-year-old, was out for a 10km jog with his older brother George when, just past the halfway mark, he became disoriented and collapsed deep in the woods. The culprit: exertional heat stroke, a condition that can escalate with terrifying speed—even when the temperature hovers around a seemingly harmless 20°C.
Here’s where the story takes a dramatic twist. With spotty mobile signal and no idea how to pinpoint their location, Will’s family faced every outdoor enthusiast’s nightmare. But George remembered a digital ace up his sleeve: the what3words app. This clever tool divides the globe into three-meter squares, each with a unique three-word address. As Laura Evans, head of operations at Lincs & Notts Air Ambulance, put it, “What3words enables our crews to locate a patient much more accurately than a postcode. This means that the crew can potentially be by the side of the patient faster, especially in remote locations such as in the woodland where our doctor and paramedic treated Will.” Over 85% of UK emergency services now rely on this technology for rapid, precise rescues.
But what if you’re out of mobile range or your phone’s battery is circling the drain? Enter the new generation of satellite-based emergency SOS features on smartphones. These systems connect directly to satellites, letting you send your location and a distress message even when you’re off the grid. While satellite phones and mesh networks can be pricey or require extra gear, these built-in smartphone features are fast becoming a must-have for anyone venturing beyond city limits. According to a recent review on first responder communication in remote locations, integrating satellite and mesh technologies is helping bridge the gap when traditional networks fail.
Will’s ordeal is a wake-up call for parents of young athletes and outdoor adventurers alike. Exertional heat stroke isn’t just a risk on blistering days. As exertional heat stroke is the third leading cause of mortality in athletes during physical activity, it can strike even in mild weather if hydration, acclimatization, and early warning signs are ignored. The science backs this up: during intense exercise, the body’s heat production can overwhelm its ability to cool itself, especially if you’re not used to the conditions or start out dehydrated. Dehydration doesn’t just make you thirsty—it thickens your blood, strains your heart, and can tip you into dangerous territory far faster than you’d expect, as highlighted in a comprehensive review of exertional heat stroke.
So what can you do to keep your summer adventures safe? Experts recommend a few non-negotiables: acclimatize to the heat with at least a week of gradual exposure, start every session well-hydrated, and don’t wait until you’re gasping for water to drink up. The latest consensus guidelines suggest drinking 6 mL of fluid per kg of body mass every 2–3 hours before activity, and keeping tabs on your weight before and after exercise to monitor fluid loss. For long runs or games, lightweight, light-colored clothing and scheduled breaks in the shade are your best friends. And don’t overlook the power of pre-cooling—ice vests, cold towels, or even an ice-slurry drink can help you keep your cool when the mercury rises.
The Coen family’s story also spotlights the importance of sharing accurate location information in an emergency. If you’re heading out to remote trails, make sure someone knows your route and expected return time. Download location apps like what3words or familiarize yourself with your phone’s satellite SOS function. And remember, in a pinch, old-school methods like signal flares or brightly colored clothing can help rescuers spot you if all else fails.
Will’s recovery—thanks to quick action, community support, and a little tech magic—serves as a powerful reminder: a few smart strategies and the right tools can make all the difference when the unexpected strikes. As Will himself now tells fellow athletes, “Listen to your body” and don’t push through warning signs. Summer adventures are all about making memories, not close calls.
