    Why does the body temperature seem to rise when napping? I've experienced this myself. Before napping everything is fine, air-conditioned room so I'm not sweating. As I doze off in a light snooze and wake up awhile later (probably about 5-10mins) I'm sweating a little and body feels hot.

    I have experienced that as well. I take a nap of 15-30 minutes and I wake up sweaty and hot. It's why I don't take naps, leaves me feeling worse then before I took the nap.


    Always minimize the variables.

    It happens to me if I've eaten. I thought it's my metabolism shedding calories.

    We're supposed to have a lower temperature while sleeping.

    Could be the body's thermal set-point wavers during sleep for some people, and you wouldn't wake and notice when you're cold.

    Be scientific about it.

    Sweating and feeling hot isn't a scientific temperature measurement.

    Next time you measure ambient temperature before napping and your core body temp (which isn't that easy, so just use an ear thermometer, or an anal one).

    Measure the two temperatures again after napping.

    Make careful notes on items you wear.

    Ideally the environmental conditions should be the same. So i suggest napping naked with the airco at the same temp (temp still needs to be checked).

    Don't forget to measure humidity.

    If it is all too much trouble, just measure your own temperature before and after.

    I would think that the bed and cushions supply insulation. It’s like putting on half of a very thick sweat suit while taking the nap.

    Sorry I meant the sensation of feeling hot and sweating after a nap. Logically body temperature shouldn't rise, if it does we would have been dead before we wake up. :?

    I don't think it is the cushions or any insulation factor. I experience it while napping on a plastic chair.

    I think that body temp will actually diminish.


    test it.

    People generally sweat more than they realise. While on the plastic chair, the sweat has nowhere to go and the cooling effect of evaporation is lost, so you wake up clammy and hot. As Spurious says, test it and let us know.

    Allegedly the body temp is lowest during rest/sleep

    http://en.wikipedia.org/wiki/Normal_...dy_temperature

    but it is just wikipedia. Didn't look up scientific sources

    I've done 1 test so far. Here are the results (in degree celcius)

    before nap = 36.5 ^C
    after nap = 37.0 ^C

    Body temperature increased 0.5^C after napping.

    I thought that our body temperature will tends to be lower when we sleep. It is because our hearts beats slower and this leads to less friction. I could be wrong

    Your body temperature is at it's lowest between 2-3am, this effects our sleep patterns. When your most likely to sleep is when your body temperature is at it's lowest. This is also related to circadian rhythm

    Then if you're sweating, that's probably part of the process of lowering your core temp. Maybe it's not because you got hotter. It's because your body has readjusted what it considers to be "hot enough to break a sweat over".
