"Is there an evolutionary reason for hot flashes? I&amp;#039;ve often wondered, and while I haven&amp;#039;t read any studies on the subject, I do have a few completely unscientific theories: 1.The first one comes courtesy of a friend who hypothesizes that menopause in general, and hot flashes and moodiness in particular, is nature&amp;#039;s way of ensuring the perpetuation of the race, for it can cause some men to leave their perimenopausal partners for younger, less oscillating and more predictable models. The problem with this is that what happens when these younger replacements hit midlife? 2.To combat global warming. Who needs to set the thermostat higher than 58 or 60 degrees in the winter when you have your own internal thermostat set near boiling? Think of the savings on energy bills! Not to mention that we&amp;#039;re helping the planet. 3.To protect against unwanted pregnancies. Despite the fact that monthlies have become quarterlies, it&amp;#039;s still possible for a woman of &amp;quot;advanced maternal age&amp;quot; to get pregnant. To combat this, she sends out a signal so her partner now knows that hot and bothered has taken on a whole new meaning. 4.To save money and thus expend less energy. Who needs to buy makeup, for example, when the blood rushing to your face gives you all the color you need? Who needs a separate wardrobe for different seasons when it&amp;#039;s always eternal summer where you live? What about you, reader? Do you have any evolutionary theories of your own that you&amp;#039;d like to propose? "^^<http://www.w3.org/2001/XMLSchema#string>
