Warming a tent?

Does anyone know if pure bees wax candles are toxic? And if so how bad/good against regular candles? Would be interested I'n knowing if I could cut down on the ventilation required to improve the heat!

The wax itself is edible, I eat it with some honeys. People use it to polish furniture and things like that with no ill effects that I know of. I haven't looked into very long-term effects, there's probably something I've missed. Things are different when you burn it, or when you burn anything for that matter. The products of combustion can be toxic. Carbon monoxide would be the biggest danger. If you cut down the ventilation that could be very dangerous in an enclosed space. It's the same with anything that uses a fuel containing carbon. Some combustion products can cause cancer with long exposures, anything which burns with a yellow flame rather than a blue one is suspect because a yellow flame is sooty. Soot used to cause a lot of cancers in chimney sweeps.
 
I often awake with cold or clammy feet even if the rest of me is (relatively) comfortable so I've been toying with the idea of getting some 'bivi boots', like slippers for tent use made out of sleeping bag material. The other one I have heard is wearing your mitts over your feet whilst asleep, or getting a lightweight blanket (poncho liner?) and bunching that up in the bottom of the bag to give it a bit more loft. Not tried these yet though...

Has anyone tried out those Zippo handwarmers? I'm not sure if they're safe for use in a bag as they burn lighter fluid, but they have to be somewhat safe to be carried in your pocket... Would give off more heat and for longer than the chemical clicky type of handwarmers, but it could also get through some oxygen if left on all night? Would be glad if someone who's used one could fill me in.

I've found that if I drink a pint or so of hot brew just before turning in, and wear a headover or woolly hat type thing whilst in a bag, I generally feel a bit warmer and sleep the sounder for it. Wrapping the bivvybag over my face or crawling down inside it just feels claustrophobic and stuffy, like I can't get enough air, but if you're going to have your head and face out then covering them up can make quite some difference to your heat loss.

I have used zippo handwarmer for camping without problem, I put it at the foot of my sleeping bag.

I read in an old book (IIRC WW1 Red Cross book) candles are ten time more toxic than wick lamps but I've no idea what wax they refer to, paraffin wax? bees wax? animal fat? tale your pick.
 
I`ve used the Optimus hiker 111 several times to heat a tent. Usually before going to sleep and in the morning when waking up.
I absolutely don`t use it while sleeping, not even when lying down (one could fall asleep).
It is a good habit to light the stove outside though.
Burning down the tent is a far greater risk than being poisoned by CO it seems. At least from newspaper writings up here.
