If you are carrying all of your gear on your back, you should do what you can to minimize weight. A sleeping bag that will keep you warm at 10 degrees in your underwear will keep you warm down to approximately 5 below zero temperatures if you're wearing insulated clothing. This means that if you expect 5 below zero temps, you should pack a 10 degree bag, not a 5 below bag.
Obviously, if you are overheating while you are sleeping, you should take off clothing and ventilate to keep comfortable. Just as obviously, if you're car camping, bring whatever you want. What I am saying is that if you care about weight (i.e. if you are climbing, or backcountry skiing, or backpacking) you should factor in the insulation value of your clothing when you choose a sleeping bag. This allows you to carry a much lighter and less bulky sleeping bag, reducing your overall burden substantially. This is not just my opinion. Every alpine climber does this. It's common sense.

I disagree, with the right temperature bag you should not have to wear every piece of clothing you brought or are carrying
you are going to perspire will you are sleeping & when you get active in the morning this will only help advance hypothermia if the conditions are right
purchase the newer moisture wicking gear, it may cost more, but you will be rewarded greatly when the time comes
you also need to stay hydrated as much in the cold as in the heat
