Meera Madhu asks:
“when we have fever we feel cold but sb who touches us feel our body temp why???????”
Human body always tries to maintain a constant temperature. When we have fever, the body temperature will be more than normal which makes us feel that the surrounding is cold. When some body touches us, he feels that our body is hotter because his body is at a lower temperature than ours.
We feel chilled in cold climate not because our body temperature is low, but because the atmospheric temperature is low.
