Spring Camping: 4 Keys to Avoid Unexpected Hypothermia

by Todd Walker

One of the top concerns of winter outdoor activities is hypothermia. We are well aware of that possibility and prepare accordingly. With summer approaching, what’s the worry?

Spring Camping- 4 Keys to Avoid Unexpected Hypothermia -

I’ve been chilled to the bone on a few spring camping trips in Georgia… especially in wet conditions. One I’ll never forget was a fishing trip my brother-in-law and I made on the Flint River in mid-March of 1981. We motored up river, set trot lines, and made camp near a sandbar. We woke to a heavy frost blanketing our lightweight summer sleeping bags under a freezing Georgia sky. We were unprepared for the evening temperature change. It was springtime!

A good scare is worth more to a man than good advice. ~ Edgar Watson Howe

Our mountain temperatures in June are sneaky and cold enough to drain your body heat by morning. On planned overnighters, having the means and skill to regulate core temperature is critical to enjoying your camping trip. On unexpected stays, it could mean staying alive.

We tend to associate hypothermia with frigid winter temperatures. However, people can die from losing body heat with temperatures in the 50 degree range. Why?

Most people take day hikes or camp in late spring and early summer unprepared for this unexpected threat. Body heat generated from hiking a mountain trail is a double-edged sword. Yes, you’re warm while active… and sweaty. The mercury drops and the wind picks up at higher altitudes. Evaporative cooling is a wonderful to a certain point. Dressed in minimal, sweat-soaked clothing, you may find yourself on a slippery slope of suffering from exposure. You must be prepared to take steps to protect from further cooling.

Hypothermia Warning Signs

Hypothermia is subtle. No matter how experienced you may be in outdoor adventures, core temperature control should be a top priority on every outing. Sadly, just two summers ago, a well-known and experienced hiker succumbed to the elements in Washington. It can happen to anyone.

Few places in this world are more dangerous than home. Fear not, therefore, to try the mountain passes. They will kill care, save you from deadly apathy, set you free, and call forth every faculty into vigorous, enthusiastic action. ~ John Muir

There are inherit risks in outdoor activities. Heck, just rolling out of bed holds its own risks. That doesn’t keep adventurous types out of the wilds. Managing risks successfully keeps us alive out there.

Here are the stages and symptoms signaling a drop in your core temperature.

Mild Hypothermia

(Body temperature between 89-95F/32-35C )

  • Constant shivering
  • Tiredness
  • Cold, pale, blotchy skin
  • Numbness and tingling skin
  • Blue fingers and toes
  • Fast breathing

Moderate Hypothermia

(Body temperature between 84.2-95F/28-32C)

  • Ability to think clearly and attention suffers
  • Confusion
  • Slurred speech
  • Lose of judgement and reasoning ability
  • Stiff muscles and cramping
  • Shivering stops
  • Slow or irregular pulse
  • Drowsiness

Severe Hypothermia

(Body temperature below 84.2F/32C)

  • Unconscious/unresponsive
  • Pupils dilated
  • Irregular or no pulse
  • Undressing and terminal burrowing occurs in 1/4 of the people who freeze to death
  • Bodily functions and organs begin shutting down

Immediate medical attention is needed to stay alive.

Reduce Your Risk

Being unprepared this time of the year is hypothermia’s power. Dirt Road Girl and I have passed many day hikers happily enjoying mountain trails in early spring and summer wearing shorts, t-shirt, and maybe a water bottle with no contingency day pack in sight.

Who knows, these folks may possess skills and fitness levels to able to construct an emergency shelter from leaves and sticks to stay warm if an unexpected stay in the wilderness happens. Unless you’re on a self-imposed survival adventure, always carry a minimum of core temperature control gear.


No matter what clothes you’re wearing, pack a 5 x 7 foot emergency space blanket. Add a cheap plastic painters tarp and you have two items used in constructing Mors Kochanski’s super shelter. My experience with this design is very favorable if you’re able to maintain a fire throughout the night.

A bright orange tarp is also useful as a signaling device. Large contractor garbage bags weigh little but offer many uses in core temperature control. I pack two.


Fire is the most forgiving of all survival skill. Even without proper cover, a good fire can keep you alive.

Carry a fire kit with redundant ignition sources: Open flame – Bic lighter, matches; Spark ignition – ferrocerium rod, flint and steel; Solar ignition – magnifying lens.

Fire and hydration

There is dry tinder material even in a wet forest. However, be prepared and carry a proven source of dry tinder in your kit. It doesn’t have to be natural material either. Commercial or diy fire starters are highly recommended when fine motor skills have said bye-bye to cold hands. Also, duct tape burns long and hot. Here’s a compact method of carrying several feet of duct tape.

For more fire craft basics, check out our Bombproof Fire Craft page.

Keep in mind that a person’s early-stage shivering may stop after being warmed from radiate heat around the fire, but their core temperature may still be dangerously low. If one person in a group is experiencing obvious signs of hypothermia, it’s very likely that others are in early stages as well. Watch out for each other and take action when needed.


A well hydrated person has a better defense against hypothermia. More fluid increases blood volume and conserves heat in your core longer than if you are dehydrated.

Carry a metal water bottle which can be used to boil water in the fire you’ve built. A hot cup of cocoa adds some warmth to the core while hydrating the body simultaneously.

Prepare for Extremes

Check the local weather report before heading out. I just returned from a weekend with our Georgia Bushcraft group. I planned to bring my sleeping bag (MSS). The weather report showed temperatures in the 80’s to the low 60’s with rain on Saturday. I typically only use my poncho liner in those temps in my hammock. However, I wanted to over-prepare. When setting camp, I realized I’d forgotten my sleeping bag. That’s why checklists are helpful… most of the time. I made do but was rather chilled the first morning.

The lesson on this trip was to double-check the checklist. Extra layers I had packed came in handy for warmth in the hammock. Plus, I had my closed cell foam ground mat which I employed. Coupled with my emergency space blanket, the cool, rainy Saturday night in Georgia posed no problem to a good night’s sleep.

Summer temperatures are headed our way. Under normal circumstances, hypothermia never crosses most of our minds this time of the year. We welcome cool breezes and rain showers. By following the above mentioned points, core temperature control shouldn’t be an issue.

The Number One Skill of a Good Woodsman

by Todd Walker

Every item in your kit should ultimately help you develop this top skill.

The Number 1 Skill of a Good Woodsman -

“The quality of a survival kit is determined by how much it can help you when you need to sleep.  If you can sleep well at night, you have it made.” ~ Mors Kochanski

I’ve shared coffee over campfires with some tough guys in the past. It’s easy to spot who is experienced in the art of smoothing it in the woods by a simple question uttered after that first sip of joe…

How’d ya sleep?

Ah yes, the moment of truth. On the second morning it becomes very apparent who’s sleeping well and who’s ready to pack up and head home to their pillow-top mattress and warm flannel sheets.

We all have our bad nights sleeping in the woods. But an experienced woodsman has developed hacks to obtain what novice campers only dream of… restorative sleep.

Owls screech, coyotes howl, and curious critters come to visit. What did we expect? We’re sleeping on makeshift beds in their “living room.”

The larger woodland animals are often deemed sleep saboteurs. Proper camp hygiene will keep most of the big guys away. Not giving attention to little details invites malicious mischief all night.

Sleep Saboteur #1: Mosquitos

There’s nothing more annoying than the distinctive, tormenting buzz around your face in the dark. Left un-swatted, one tiny mosquito in a shelter will ruin any chance of sleep.

Get the picture…

You lay motionless, radar on, to detect its airborne location before the nighttime bombing raid commences. The constant hum gets closer and stops when the bloodsucker lands. You swat – and miss – and swear. The dive bombing continues till dawn. Itchy welts on your forehead, the only exposed human tissue in your shelter, resemble a measles outbreak by morning.

Here are few modern and primitive ways to get a good night’s rest in bug season.

Bug Netting

Defensive maneuvers can be deployed to defend your skin. Modern mosquito netting adds little weight to your pack and provides protection from even smaller no-see-ums (biting midges).

ENO Guardian Bug Net

ENO Guardian Bug Net

Dirt Road Girl bought me a ENO Guardian Bug Net to use on our trip to Eagle Rock Loop this summer. I only used it the first night. The net stopped the bugs. But it also stopped some of the breeze. I hate sleeping hot.

Bug Dope

The industry standard to keep bugs off is DEET. The problem I have with this chemical is ~ if will melt plastic, I don’t want it on my skin. I opt for natural bug-off protectants.

BugShot even works on ticks

One all-natural repellent I’ve been using this summer is called All Natural BugShot. I love this stuff! Here’s a quick video of my thoughts on BugShot…

The plant world provides a natural defense against biting insects. Here are a few that I’ve used and found effective in my area. Simply crush the leaves to release the oils and smear the material on your skin and clothing.

  • Wax Mertle (Myrica cerifera) – abundant on our middle Georgia family land and used often
  • American Beautyberry (Callicarpa americana) 
  • Paw Paw (Asimini triloba) 
  • Yarrow (Achillea millefolium) – found along open fields and hedgerows before you hit the deep woods

Smudge Fire

Even if you can’t find these natural bug repelling plants, you have woody plants in various stages of decay no matter where you are. Look for a dead limb or stump containing punk wood; decaying wood that is spongy but not rotted to the point of crumbling to dust.

You knew I’d highlight the importance of fire craft in wilderness self-reliance, right?

Once you have fire, light a chunk of punk wood and let it begin to smolder. If you have a metal container, add a layer of burning coals to the bottom of the container. Then add the punk wood on top. Now you have a smudge pot that can be moved to take advantage of wind direction in your shelter area.

A few holes in the bottom of the container will add just enough oxygen to keep the smudge smoldering for hours. However, you don’t want to ruin a perfectly good metal container with holes. Use an old tin can or other container using your possum mentality.

A shallow hole in the ground with smoldering material will serve the same purpose – only it’s not mobile. Animal dung, composted plant material, pine needles, and other weeds on top of coals will create long-lasting smoke. Let’s not forget about the usefulness of smoke to rid natural bedding material of my arch enemies in Georgia… chiggers and ticks!

Sleep Saboteur #2: Bedding

Staring at my mid 50’s, the need to impress others has departed like the hair on my head. I’ll take smoothing it over roughing it any night in the woods!

Personal preference dictates whether you hang in a hammock, sleep on the ground, use a sleeping bag, or a wool blanket. I’ve used all of the above. Given the option of ground or hammock, I choose to hang around camp!

Go Light

Weight isn’t an issue when car camping or RV’ing. Even canoe camping will trim your load considerably. Bushwhacking on foot takes a bit more thought on your sleeping arrangements. Long before today’s modern camping gear and gadgets, our ancestral woodsmen slept in the wilderness comfortably.

The temptation is to buy this or that indispensable camp kit has been too strong and we have gone to the woods handicapped with a load fit for a pack mule. This is not how to do it. Go light, and the lighter the better so that you have the simplest of material for health comfort and enjoyment.  ~ Nessmuk


When your body comes in contact with cold or wet ground, heat transfers (conducts) away from your 98.6ºF body. Sleeping cool is one thing, sleeping cold can kill.

I use a cheap closed-cell foam sleeping pad in both my hammock and on the ground when temperatures drop. This insulates my backside from the effects of convection in the hammock and conduction when sleeping on the ground.

Other primitive insulators are available in the forest if you ever find yourself in a situation without modern gear. A six-inch layer of compacted leaves, pine bows, or other fluffy stuff can serve as a barrier between you and the cold ground.

“It is one of the blessings of wilderness life that it shows us how few things we need in order to be perfectly happy.”  ~ Horace Kephart

Sleep Saboteur #3: Heat Loss

I sleep best in cold weather. To do this, I take steps to control heat loss.

Here are key terms to know for core temperature control:

  • Conduction – The transfer of heat when ‘hot’ molecules collide with neighboring cold molecules. Heat travels from hot to cold via touching.
  • Convection – Air or water moving over skin removes heat from your body.
  • Radiation – The process where energy (body heat) is transferred in space from our body and absorbed by a colder environment. Heat, light, and sound travel by waves, particles, or rays.
  • Insulator – Materials that are poor conductors of heat. Air, cloth, and wood are poor conductors but make great insulators.
  • Heat transfer – Thermal energy (heat) can be transferred via conduction, convection, and radiation.

To sleep cozy in the woods, pay particular attention to the following…


Your most important layer of shelter is the clothes you wear. Without feather or fur, humans wear clothing to trap a warm pocket of insulating air being radiated from the body. Our head and neck are responsible for radiating about 75% of our body heat into the environment. That’s why wearing a hat keeps your feet warm.

Outside the clothes you’re wearing, another layer of shelter can be made from tarp, tent, or natural material. It’s worth noting here that attention to the 4 W’s of campsite selection (Wind, Water, Wood, and Widow Makers) increases your chances of peaceful sleep. I’m fond of tarps due to their flexibility in configurations. Other advantages of tarps include:

  • Lighter than tents
  • Quick to set up if caught in a rain storm
  • Can be set up to passively collect said rain water
  • Perfect companion for hammocks
  • Cheaper to buy than tents
  • Easy to configure to block wind, rain, or snow – or open up to take advantage of wind in hotter climates
  • You can make your own
  • A radiant fire out front adds warmth and offers wilderness TV entertainment as you nod off to sleep

A few modern shelter/cover options in my sleep system are…

  • ENO ProFly – lightweight (1.4 pounds), compact, and easy to set up
  • SOL Emergency Space Blanket a 5 x 7 space blanket used in the Kochanski Super Shelter design for extreme cold and little gear
  • Trash Bags – two contractor grade trash bags stay in my kit and could be used for emergency shelter or stuffed with fluffy debris for bedding
  • US Military Modular Sleep System (MSS) – this system consist of two sleeping bags, GoreTex bivy bag, and compression stuff sack – I only take the components I think I’ll need, never the whole system

Other Sleep Aids

The first thing I do when making camp is to build a fire. I’ve made it a habit to wash my body before going to sleep. After bathing I stand by the campfire to dry off. This one act helps me sleep the sleep of babies. A little nightcap never hurt either.


A poncho liner (A.K.A. – woobie) has saved me a time or two in what I expected to be warm camping weather which turned cool unexpectedly. My nephew, a veteran of the Afghanistan war, always carried a woobie. Leaving this piece of gear behind, he was told, would ensure that you “woobie” cold.

Dedicated wool socks for sleeping accompany me on overnight trips. These clean socks are only worn in bed.

“One of the hallmarks of the veteran woodsman is the way he contrives to make himself comfortable in camp”. ~ Warren H. Miller

Experience in the finer aspects of woods lore can only be learned by Doing the Stuff in the wildness. Fall temperatures haven’t arrived in Georgia yet, but I know they’re coming. I for one can’t wait to get out and sleep in the woods!

What’s your best tips for sleeping soundly in the woods?
