I have an uber safety conscious son who won't run the Little Buddy at night. I guess it could be worse. I could have a son who juggles knives or something. :)
Yes, it's the breathing the frigid air that keeps me up.
Good for your son! I almost succumbed to CO poisoning in a TC as a teenager and am uber careful too.
If it is breathing cold air that is the main issue for you, find a way to warm just the air near your head when sleeping. Maybe one of the aforementioned small defroster heaters. Even a light bulb in a box and a small computer fan may work for you. You may also need earplugs to mitigate nearby fan noise.
Edit: A few years ago I built a small heat exchanger that brought in fresh air and retained 80% of the heat from the exhaust. It used 1-1/2 inch diameter plastic hose to put the incoming air where I wanted it. The fans and exchanger were in a standard plastic ammo box. The same style box, fan and hose could be designed with a light bulb in the ammo box to put warm air where you want it.
Hope this helps,
