What is your burn rate of cal/hr while asleep?

Anyone using the tech to find this info? Do you use any heart rate devices?

Dont know about sleeping, but had a test done at my doctor and she said I burn 1950 cal per day just staying alive. So if I sat on the couch all day I would burn over 2000 cal.

Whatever that is worth.
