I totally agree with you. I'm usually somewhat okay during the day. The
worst flushing attacks always seem to come at night. I do flush during
the day sometimes but the intensity is definitely greater at night.
Heat has always been a huge flushing trigger but I would say the
biggest for me is simply stress. I also blush a lot too and the
blushing then turns into a longstanding flush.
I live in the midwest where the winters are very cold. The worst part
for me now is drastic changes of temperature. I'm out in the cold for a
prolonged period and then go inside to a warm house, I will most
definitely flush for a while. But this only happens when I go from
really cold to really warm.
