I get them randomly but find that fans and cooler temps do help quite a bit. When I was walking outside during the summer, I really, quite honestly, couldn't even tell when I was having a hot flash anymore because I was just so hot, LOL. One thing I have noticed that helps is not wearing socks. For some reason, my feet are like car radiators - if my feet are cool, I stay cooler. It's weird but it's the only thing that consistently helps. I also, wear light clothing. I'm a QVC nut, so I buy a lot of Susan Graver's liquid knit clothing and Renee Greenstein's como jersey clothing. That helps a ton!!!! It is rather life-changing.
