It's a
common phenomenon; a man complains he's feeling too hot and throws off
the duvet while his female partner burrows under it and wishes she had
some woolly socks.
While
each partner accuses the other of complaining, the difference between
male and female temperature control is not simply hearsay.
In fact, there are proven differences between men and women when it comes to the way their circulatory system functions.
Women
are better at conserving core body temperature - to keep a developing
foetus warm - while men's can drop slightly without them noticing.
