why are sheets still cold even if you’ve been under think blankets that are supposed to trap in heat?

I’ve always been confused about this because I sleep under many thick soft blankets yet my sheets always seem to be cold when they should warm up from being trapped in my body heat.

Blankets slow, but do not completely stop, the process of heat loss.

When you are in bed, the heat your body generates replaces any heat lost through the blankets.

When you leave the bed, the sheets still retain the heat from your body. However, since you have left the bed, the sheets will also slowly lose heat despite being covered by thick blankets.

it also depends on the material the sheets are made from. a percale cotton or linen sheet will feel cool by design. a flannel sheet will feel warmer by design.

Because there’s not really much to them, so they don’t hold in the heat that was put into them.

Sort of like how tin foil doesn’t stay hot very long after you take it out of an oven. The material is so thin and has a lot of surface area that the heat radiates back out of it pretty fast.

Do you tuck your sheets in under the mattress or are you wrapped up burrito style?

If your sheets are tucked under the bed instead of wrapped up a lot if heat can escape that way. The thinner the blanket the less heat it holds in as well. So when the blanket does not hold in enough heat to overcome the cold air coming from underneath the mattress you get cold sheets.

This could be the issue of the *feeling* of hot or cold being related to the heat transfer and not the temperature. Your body is generating heat and shedding it.

I’m unclear on what the situation is, like when are you feeling the sheets are cold, how does it compare to a room temperature bed when you first get in?
