I had to look up this info after talking with Andy about this topic.
Apparently, the core temp of a woman is .4 degrees warmer than a man's. But the temp of a woman's hands .8 degrees colder than a man's.
Plus, a woman's menstrual cycle also lowers & raises her core temp.
And older woman (postmentrual) have lower temps than premenstrual woman.
So, guess it would be safe to say that a woman's body temperature changes more often than a man's and so we might notice a change in our body temp.
