How to recognise and manage cold injury in UK outdoor settings. 

Keeping with last weeks theme on hypothermia. 
 
You’re a couple of hours into a winter day outside. 
 
Nothing dramatic — just wind, drizzle, damp gloves. 
 
Someone mentions their fingers feel numb. They shake them out and carry on. 
 
That’s often where cold injury begins. 
 
In the UK, cold injuries rarely arrive with drama. They creep in quietly — and they’re more common than many people realise.

Why wind, rain, fatigue and calories matter more than the thermometer 
 
Most people think hypothermia only happens in extreme cold. 
 
Minus temperatures. Snowstorms. Arctic conditions. 
 
The reality is very different — and far more relevant to anyone spending time outdoors in the UK. 
 
Every winter I see the same misunderstanding: 
“It wasn’t that cold, so hypothermia wasn’t a risk.” 
 
That assumption is exactly how people get caught out. 
 
Hypothermia is about heat loss exceeding heat production. Temperature is just one small part of that equation. 
 
Let’s break down what really matters.

What Outdoor Leaders and Schools Need to Know 

First aid guidance changes for one reason only: to help more people act sooner, more safely, and more effectively in real emergencies. 
 
The Resuscitation Council UK (RCUK) 2025 Guidelines introduce several important updates that directly affect schools, outdoor education, activity centres, and youth organisations. These updates clarify who should do what, simplify decision-making under stress, and better reflect the types of incidents that happen in playgrounds, on trips, and in outdoor environments. 
 
This article explains the key changes, with a focus on paediatric care, trauma management, and practical first aid in outdoor and school settings.

RCUK 2025 Life Support Guidelines: What’s Changed—and What It Means for the Outdoors 

Short version: call 999 sooner, start compressions fast, defib early, and—when you’re trained and equipped—don’t neglect ventilation. Below is what’s new, what’s reinforced, and how to apply it when you’re miles from a road. 

What Modern Guidance Actually Says 

For years, first aiders were taught one rule above all others: “Don’t move them!” 
Back then, “immobilise the spine” meant collars, backboards, and keeping casualties perfectly still at all costs. 
 
But modern research — and new guidance from both the Wilderness Medical Society (WMS, 2024) and the UK Faculty of Pre-Hospital Care (RCSEd, 2025) — has changed the way professionals and rescuers think about spinal care. 
 
Today, the goal is Spinal Cord Protection (SCP) — not rigid immobilisation.

Broken Femur First Aid: Why 999 Comes Before Splinting 

A broken femur (thigh bone) is one of the most serious injuries you can face outdoors. It’s not just a painful fracture – it’s a life-threatening emergency that can cause massive internal bleeding and shock. It can kill you, the casualty needs to be in hospital ASAP, with safe, expedient evacuation. Not an orange survival bag, six rocks, a broom handle and a wish and a prayer. 
 
So what should a first aider actually do? Do you call 999 and wait, or do you try and splint the leg with sticks and bandages? 
 
I can remember early in my career, outdoor courses making improvised traction splints, it was a laugh and we thought it was cool. Three decades down the line and having attended serious fractures of the pelvis and femur, it is not a laughing matter. 
 
It is not as easy in real life as it is in a classroom, it is incredible painful and the risks are high if you cock it up. Add to that, we will have to take everything off to put proper splints in place. More movement, more pain, more time wasted. 
 
Let’s break it down.

Why schools ask this question 

Headteachers, trip leaders and compliance officers often ask: 
“Does Outdoor First Aid count as workplace first aid for staff?” 
 
The short answer is yes. The Health and Safety Executive (HSE) recognises Outdoor First Aid (OFA) as equivalent to workplace first aid when it meets the right standards. That means schools don’t need to book two separate courses – OFA can cover both classroom compliance and off-site safety.

When people think of outdoor learning, they picture freedom, challenge, shiny gear and adventure — not paperwork. But for those managing outdoor centres or school trips, compliance isn’t just admin. It’s the foundation of safe outdoor education, protecting participants, staff, and your organisation’s reputation. 
 
Having been a member of AHOEC and AAIAC while managing outdoor education centres and recruited outdoor instructors, I’ve seen how compliance sets professionals apart. It builds trust with schools, parents, and clients — and ensures outdoor learning remains safe, credible, and sustainable. Schools and clients are interested in due dilligence, local authorities emply an Outdoor Education Advisor and private schools will have a staff member designated to fullfill this role. 
 
On the 16th of August, I had the pleasure of working with the other regional Mountain Training Co-ordinators running a training day for Mountain Training Association members here in the Chiltern Hills. Coombe Hill, with its mix of woodland, rolling chalk escarpments and wide views across the Vale of Aylesbury, proved to be the perfect outdoor classroom. 
 
The day was designed to bring together core skills that every outdoor leader should have in their toolkit: first aid, navigation, and local knowledge.

We’ve all seen it — a slip on wet rock, a poorly ducked branch, a flying elbow in a group shelter. Head injuries happen fast and without warning, and in remote places, it’s up to you to manage the situation until help arrives — or until you walk them out. 
 
👤 “I’m fine.” – The Famous Last Words 
Mild head injuries often look like nothing. A bit dazed, maybe a scratch or graze. But beneath that could be a concussion — a brain injury. And in rare cases, a serious or even life-threatening problem. 
 
In the hills, we take every head injury seriously. Especially if: 
 
The casualty was knocked out, even for seconds 
They seem dazed, slow or confused 
They complain of nausea, vision changes, or a headache 
Their behaviour just seems… off

Head injuries are not just from regular sports. Outdoor activities are a high risk for head injuries. Always wear a helmet. Prevention is better then cure.
