⛺ Camping Physics – How to Stay Warm (or Cool) in a Tent
Whether you’re pitching up on a windswept hillside or a sunny coastal meadow, your tent becomes your home – and your personal physics lab.
Staying comfortable while camping is all about understanding heat transfer: conduction, convection, and radiation.
🔥 The Three Ways You Lose (or Gain) Heat
1. Conduction – The Ground Beneath You
The Earth is a giant heat sink. Lie directly on it and you’ll lose heat fast.
-
Tip: Use a sleeping mat or inflatable mattress to trap insulating air between you and the ground.
-
In summer, the same principle works in reverse: a groundsheet can help stop the hot earth from radiating heat up into your tent.
2. Convection – Air Flow in the Tent
Air moves heat around. In winter, unwanted draughts suck warmth away; in summer, a breeze is welcome relief.
-
Tip: Adjust vents strategically. Close them on cold nights, open them fully on hot days.
3. Radiation – Heat from the Sun (or You)
On a sunny day, a tent can turn into an oven thanks to solar radiation heating the fabric and the air inside.
-
Tip: Choose light-coloured tents in hot climates to reflect sunlight, and dark-coloured tents in cooler seasons to absorb warmth.
🧠 The Physics in Action
-
Winter Camping:
Your body generates heat (metabolic radiation), which gets trapped in your sleeping bag.
Reduce conduction by using mats, stop convection with draught stoppers, and minimise radiation loss by using reflective liners. -
Summer Camping:
Position the tent in shade, encourage convection by creating cross-breezes, and reduce radiant heating by using reflective flysheets.
🛠 Simple Experiments for Students
-
Conduction Test: Place a PASCO wireless temperature sensor under different sleeping mats overnight and compare data.
-
Convection Observation: Use smoke or a fine mist to visualise airflow patterns through tent vents.
-
Radiation Check: Measure inside temperatures of light vs dark tents under the same sun.

🏕 The Takeaway
Camping comfort isn’t just about buying the right gear – it’s about using it with an understanding of physics. Master heat transfer, and you can sleep soundly whether it’s frosty or sweltering.
