why do you treat caves atmosphere the same as the surface wht would you have the temp drop in sider a cave as if I were out side we all know caves hold there Temp, RH with vey little change from day to night i think you need to relook at the envirmently parameters. As one shoujld be able to use caves as a place for shelter but you can if the caves get to -60 or -83 just as if I were out side under the stars sure does not make any sens
