Funny thing about hot flashes...

So, I know to expect a hot flash with my morning coffee and as soon as I get into bed at night. I usually have one in the evening around 9:30 or 10. I can't seem to figure out what triggers them other than caffeine. A few weekends ago I had a two-day class to attend and I was worried about being anxious and having sweat dripping down my forehead. During the day there were several times that the presenter lowered the lights for a video. That is when I had a hot flash--every time the lights went down! I'm still trying to figure that one out! This past week I went on a night hike for several hours and the temperature dropped down to 19 degrees. Do you think I had even one hot flash? Nope. My personal furnace failed me. I had to laugh at that!
