Definitive Ground Camping: How to Manipulate Radiant Heat to Stay Warm (Part 1)

This video from David Canterbury breaks down the real science of staying warm while ground camping, focusing on practical bushcraft skills rather than myths. It explains how body heat, clothing, fire placement, and thermal mass all work together, and why small changes in distance or setup can drastically affect warmth due to heat loss principles like the inverse square rule. The key takeaway is that proper shelter design and understanding how heat behaves are essential for staying warm overnight in cold conditions, especially in survival or off-grid situations.
