Sleeping Warm Wild Camping

A few years ago I promised myself that I would get out on the fells ‘whatever the weather’. This included continuing my obsession with wild camping on summits.

After freezing my nips off a couple of times I set out to master the conditions so I ask…

‘How do you stay warm at night?’ OR more accurately…

‘How do you produce enough body heat to have a comfortable night whilst camping at altitude in freezing conditions?’

Getting it wrong can make for a miserable night, hypothermia or worse (you know, death).

Many people every year underestimate the power of the weather. When you follow the Mountain Rescue pages on Facebook or know members who have been involved in rescues (and recoveries) you get the idea that some hikers leave their common sense in the car park.

Producing body heat whilst wild camping in freezing conditions.

This is not a regimented ritual!


Before getting in the pit I’ll boil up 750ml and put 500ml in the bottle with a Red Bush tea bag (it’s caffeine free so won’t keep you up all night and it does not stew), the now hot water bottle goes in the sleeping bag, the rest of the water is for my supper.

Typically, I’ll throw a cup-a-soup in with one of my dry-packs (crushed instant noodles, dehydrated vegetables with quorn or chicken, carbs are not your priority here, you must have fat!) and whilst I’m simmering it for a couple of minutes I’ll hold the AK BruKit between my thighs to warm the blood heading for my cold toes then turn gas off and let it steep there for another few minutes.

When a client comes out camping I’ll include food. Below is a typical menu for 24 hours.

In the bag

When I’ve eaten my granary bread and soup I’ll get in my bed with the hot water bottle. In an hour or two the tea will be the right temperature to drink so if I’m not asleep I’ll have something hot to drink. If I’m asleep for hours then I don’t need to drink it. If the hot water bottle contents make the morning the tea can simply be heated for a quick drink.

During the night

Whenever I wake up I eat nuts, dried fruit and even chocolate. Fat needs heat to be digested. Our body produces this heat to break down the fat. This heat keeps us nice and toasty. You might even try taking a ‘miniture’ bottle to bed with you, not filled with alchohol but olive oil, sip it, you’ll soon warm up.

Keeping tabs

I keep a thermometer in the sleeping bag inside pocket to compare my nights, outside my tent all of my camps have been around or below freezing this year, I’m getting a constant 30c in the bag though – this heat is produced by yours truly.

Call of Nature

A wide mouth bottle or a lockable plastic container are good for peeing into. I use it as another hot water bottle which I hold between my thighs to warm the blood heading for my toes. Having to unzip the sleeping bag whilst I perform this task reduces the temperature by 2 degrees. Getting out would waste so much heat.


I wear a base layer, Berghaus hat, snood, walking socks and tie the cord in my AlpKit 700g down sleeping bag around my neck with a slip knot (the toggle thing isn’t tight enough, note to self, must purchase a better one before next winter).

The morning after

The nights are long when you’re turning in at 7 or 8. I get up early anyway so I’ll wake at about 4 or 5. When you’re with a party who get’s up late you’re in for a long cold wait unless you have a similar morning ritual as the night before. I woke early one time with a group who didn’t stir until 9:30! I really have to give a group some times like up for 8 and out for 9.

When I camped at the frozen boggy Three Tarns at the top of the Haha Valley after a day of thick fog I woke at 5:50 to a very welcome sunrise – I could see the sunrise! The fog had cleared. This was exciting. It meant that we would be continuing our walk. After tea and food within a hundred yards we were climbing a very steep ascent of Bowfell in a 6 inch blanket of snow! Getting warm was very important, our climb certainly did this.

Now, we’re back on track, day 2 is going to be a good one!

Now it’s your turn

Preparation starts at home, it’s the most important bit of course but despite the cold and the burning desire to just get in your sleeping bag it’s very important that you follow some kind of routine of your own design to get warm, stay warm and have a comfortable night. After a 5 hour trip to the Priest Hole cave in Lakeland I got straight into my bag exhausted thinking the meal at 8pm in the restaurant would do. I woke at 2 frozen, it was -15c. I quickly made my supper and was warm within an hour. What an experience but if I allowed this to happen to a client they may be really pissed off!

This is the view next morning. Priceless. I do this camp as a Private Wild Camp or part of a Private Expedition.

All of this, hypothermia, emergency procedures and much more is covered in our Wild Camping Workshop or a Private Expedition.
