    hi!

    i have a little question about the weather. (i dont know if this forum is the right one). the temperature that all the newspappers, weather channels, etc show us, is measured in the shadow. for example, 31째 means, on this day the temperature in the shadow will be 31째. is that right?

    and other question, if we are at 1pm right under the sun, (with 31째 in the "shadow") the temperature in the sun is considerably higher?

    i ask that, because i made an experiment, taking the temperature in a room (27째) and then i puted the thermometer right in the sun, and the scale was in more than 55째 and a friend said thats impossible.

    thank you!

    the body temperature is 37째C, not 31. But i dontr get what youre asking. But the skin could get that hot and then our body have a very hard time cooling itself.

    Our internal temperature stays close to the target temperature of around 37 degrees. This assumes:
    a) We are not ill.
    b) We have taken sufficient water.

    The body will happily regulate our internal temperature by heat transfer via adjusted blood flow rates and locations, and by sweating. Why do you think you turn red when you exercise vigorously. The body increases the flow of blood to the skin so that excess heat can be radiated away.

    Thermoregulation is the ability of an organism to maintain its temperature within an optimal operating range. It is what I described in my post further up the page. You can find a fuller discussion of it on wikipedia:
