Sleeping warm
A nice pair of socks, a warm hat, and long underwear can go a long way toward keeping you warm. But don’t wear too many clothes that it compresses the insulation in your sleeping bag, that would reduce the bag’s dead air space which would ruin its ability trap heat.
Heat water, pour it into a bottle, wrap it in clothing, and put it next to any cold spots in your bag. Just make sure it can’t leak!
Sleeping bags trap heat, but can’t create it. If you enter your sleeping bag cold, you’ll stay cold for a long time. Ways to get warm before you get into your bag include drinking or eating something warm. Making a fire before bed. Doing some jumping jacks.
Peeing during the night will help you sleep warmer and better for the rest of the night. There is the option to pee into a bottle (obviously easier for men, but also possible for women). You get to stay in your sleeping bag and now have a warm bottle.
Placing a couple hand warmers at your feet helps a great deal to keep your feet warm through the night - MO

Wear minimal layers, wearing a bunch of layers will diminish the effectiveness of your sleeping bag and make you colder - MO
do some jumping jacks or some quick form of movement/exercise to warm up ur body and therefore your sleeping bag (AC)

Sleeping Pads: A layer of insulation between you and the ground, reflects back warmth and adds comfort to the sleeping system
(AM)
Foam Pads
Pro: can be cut into multiples pieces for packing and using as barriers between you and the ground for multiple people to sit on
Pro: can be rolled into a tube or folded flat against the back of your pack to add structure and make packing easier and more balanced.
-
-
Pro: quick to dry, won't absorb water
-
In cold temps, can be combined with an inflatable sleeping pad to increase thermal retention - MO
could be harder to pack in this situation-might end up on the outside of your pack which you should try to avoid (AC)
-
-
Could be used as emergency equipment to create splints, warm someone up faster (AC)
-
Inflatables
Pro: Adds a thicker layer of dead air space between you and the ground, and is therfore warmer
Con: can pop, requires a patch kit in case it needs to be fixed, useless if it aquires more holes than patches

-
con: can get wet and absorb water, takes a while for it to dry back out (CL)

Air Mattress - Made of PVC, very inflatable material MW
-
-
Con: Will not work at all if there is even the smallest puncture in it, very hard to patch as well. MW
-
-
Con: Due to too much air in the mattress to heat up with body heat and become dead air space, mattresses are very cold. This compromises the sleep system. Not insulated MW
In conclusion: These compromise the sleeping system in the backcountry and should not be used at all if going camping. MW

positioning in the tent
stay away from walls especially if its a single layer tent, the dew and moisture will seep through(NB)
