I doubt if you used both of them at the same time at level one that your body would become dangerously overheated... (well, mine would, but ... :)

however, I don't have any type of heated covers, etc... your dr could probably give you a more certain answer!

Thank you very much for your reply, busybee3.

I need to clarity that it is overheating of the electric bedding (not of me) that I am concerned about (and I think the Institute is warning about).

hmmmm, I wonder! I would have thought that would mean overheating of the body which can be dangerous! (same idea as not keeping a hot tub too hot...)

it might be worth an email to the 'electric blanket institute' if possible...

I don't see how you could overheat the bedding without overheating yourself (assuming you don't plan to turn them on when you aren't in the bed).

Even in preheat mode (which is commonly used, and used by me, before one gets in bed) they aren't hot enough to overheat me. Though then I turn it down to the lowest setting for the night.

Are you sleeping, or making paninis?

I would suggest you call your primary care physician. People's needs and concerns vary. Like busybee, I think they are talking about you overheating.

I have chronic low BP, I cannot go in hot tubs, I almost immediately pass out. My son is T1 Diabetic he cannot go in hot tub, his blood sugar goes very low, very quickly- because insulin absorption time is drastically changed.

I just spoke the the manufacturer: they confirmed that they definitely are talking about the product overheating, not me.

What if you turned one on to preheat and waited for it to warm the other. Then climbed into bed and switched which one was on?

That's a brilliant idea!

Excellent thinking, crl_! I was thinking I'd need to Preheat (I always do so out of bed) both during separate 30-minute periods, but OF COURSE YOU'RE RIGHT, either one will warm the other!! As I tend to do I was overthinking it.

I think once the preheat period is over (and it reverts to the "1" I always then leave it on), I may wait a few minutes before turning the other item of electric bedding also on to "1".

Coyote2, what brand is your mattress pad? I say no to the use of heating blanket with the mattress pad.

I think it would be fine. I can get very cold in deep winter and have always used a heated mattress pad which sometimes is on high all night. I also have 2 blankets and a heavy fake fur throw on top of me. I have at times thought about getting an electric blanket too but I don't like feeling wires with my toes when I've used them in the past.

I like the house to be quite cold at night, 60 is nice. Then I can turn the fire on in the morning and that is cozy.
