How can I prevent heat loss in my tent?

To prevent heat loss, choose a well-insulated tent. Ensure it’s properly sealed, especially around the zippers and seams, to block drafts. Use a tent footprint or insulated ground pads beneath your sleeping bag to keep warmth and heat in tent from escaping through the floor. You can also add a reflective emergency blanket on the tent's inner walls to bounce heat back. Additionally, avoiding opening the tent frequently helps retain warmth inside.
