Outdoor Injuries You Don't Expect: How to Be Ready When they Happen

“Outdoor Injuries You Don’t Expect — and How to Be Ready When They Happen”
Intro:
The outdoors offers freedom — but it also demands respect. Whether you’re hiking, mountain biking, camping, or chasing elk through the timber, nature doesn’t follow safety rules.
Most people prepare for the obvious: cuts, sprains, bug bites. But the injuries that turn a trip into a rescue mission are the ones few see coming.
According to the National Park Service, more than 3,000 search and rescue missions occur annually in U.S. parks alone, with medical issues accounting for nearly 50%. The top culprits? Falls, cardiac events, exposure, and trauma.
As emergency medicine physicians and outdoor enthusiasts, we’ve treated these cases — and we built the PrepEM Wild Essentials Pro Kit so that when things go sideways, you have the tools and knowledge to act like an ER doc until help arrives.
1️⃣ Cardiac Events in the Wild
You don’t need to be scaling Everest to stress your heart. Sudden elevation changes, heavy packs, dehydration, and adrenaline spikes can trigger cardiac events even in “fit” outdoor athletes.
A CDC analysis found that heart attacks account for 25–30% of wilderness fatalities, often striking experienced hikers and hunters over 40.
Prep Tip:
• Warm up before strenuous activity — don’t go from car to climb.
• Stay hydrated and eat regularly (dehydration thickens the blood and stresses the heart).
• Recognize red flags: chest pressure, shortness of breath, dizziness, nausea.
• If suspected, stop immediately and chew 325 mg aspirin (if not allergic).
• Keep someone with you — most cardiac arrests in remote settings occur alone.
2️⃣ Falls and Fractures
Whether slipping on wet rocks, tumbling off a mountain bike, or missing a foothold on scree, falls are the #1 cause of outdoor injury. The Wilderness Medical Society reports that falls account for over 40% of evacuations from backcountry areas.
Even minor falls can hide major damage — spinal fractures, internal bleeding, or concussions.
Prep Tip:
• Always assess mechanism of injury: how far was the fall, and what did they hit?
• If neck/back pain or numbness occurs, stabilize and avoid movement. Read our NEXUS criteria post for appropriate screening measures.
• Use the SAM Splint (included in the Essentials Pro Kit) to immobilize limbs or fractures.
• Watch for confusion, vomiting, or one-sided weakness — possible head trauma.
3️⃣ Bleeding and Penetrating Injuries
From broken glass at camp to knife mishaps while cleaning fish, severe bleeding can occur anywhere. A deep laceration or puncture wound can become life-threatening in minutes.
The Stop the Bleed Initiative estimates that uncontrolled hemorrhage can cause death in under 5 minutes, but with a tourniquet or hemostatic gauze, survival exceeds 90%. Read our posts on Tourniquet care
Prep Tip:
• Apply firm, direct pressure immediately.
• If bleeding continues, use WoundClot gauze to accelerate clotting (in the Pro Kit).
• For extremity bleeding, apply the Snakestaff ETQ Gen-2 tourniquet 2–3 inches above the wound, high and tight.
• Note the time — safe for up to 2 hours, and amputation risk remains below 5% if used correctly.
4️⃣ Hypothermia and Environmental Exposure
Cold, wet, and bleeding — the combination that kills quietly. Hypothermia can set in fast even above freezing, especially when clothing is wet or blood loss is significant.
Data from Wilderness & Environmental Medicine show that mild hypothermia impairs mental function by 20–30% — meaning poor decisions compound danger.
Prep Tip:
• Always carry a thermal emergency blanket (included in the Essentials Pro Kit).
• Change wet layers quickly and insulate from the ground.
• Treat bleeding first — blood loss accelerates heat loss.
• Feed and hydrate early; metabolism generates warmth.
5️⃣ Environmental Illnesses: Heat, Altitude, and Allergic Reactions
Outdoor environments can trigger medical emergencies unrelated to trauma.
• Heat exhaustion and heat stroke spike core temperature above 104°F.
• Altitude sickness can develop at just 6,000 feet.
• Anaphylaxis from insect stings or food allergies can close an airway in minutes.
Prep Tip:
• Take rest breaks and monitor for confusion or headache — early signs of heat illness or AMS (acute mountain sickness).
• Always carry antihistamines and, if prescribed, an epinephrine auto-injector. Read our blog post on anaphylaxis
• Elevate and cool victims of heat stroke, rewarm slowly in hypothermia, and descend promptly for altitude issues.
The Prepared Mindset
Preparation isn’t about fear
When you carry the right gear and understand the physiology behind emergencies, you replace panic with purpose.
That’s why we built the PrepEM Wild Essentials Pro Kit — compact, durable, and physician-designed to handle real-world trauma. Each component — from WoundClot gauze to Snakestaff ETQ Gen-2 tourniquet, SAM splint, and thermal blanket — exists for one reason: to buy you time and save a life until rescue arrives.
Be the asset — not the liability.

Q&A
Q: What are the most common outdoor injuries?
Falls, cardiac events, and environmental exposure top the list, far surpassing animal attacks or weapon injuries.
Q: What’s the safest way to treat severe bleeding in the field?
Apply direct pressure, use hemostatic gauze (like WoundClot), and apply a tourniquet high and tight if bleeding persists.
Q: How can I prepare for emergencies while hiking or camping?
Carry a trauma-capable kit like the PrepEM Wild Essentials Pro Kit and learn basic wilderness first aid principles.
Every mile off the grid increases your responsibility to yourself and your crew. Whether it’s a mountain trail, a hunting ridge, or a family hike, medical preparedness turns danger into survivable moments.
Stay Prepared. Stay Wild.
