Of all the things you are NOT going to have to worry about, sleeping at

True, but you can still get cold in the night. Its a common myth that
a good tent will keep you warm. The human body just can't actually
produce enough heat to really raise the temp of an entire tent.
However, a good ground cover (like a terma-rest) will prevent much of
the lose of heat (which happens through the ground or through an air
mat).
