Hot flashes are weird.
They sneak up on you, while you’re minding your own business and, “POW,”
like a lightning strike, a surge of electrical hot flames billow from your core
to your face until sweat is dripping from your forehead, neck and middle of
your back. Remarkably, your body
temperature remains normal despite the fury inside. Even thinking about a hot flash or the
tiniest bit of exertion (such as tying one’s shoes) can cause a fire to stir inside
one’s body. Although hot flashes occur
in more than 2/3 of North American women and nearly all women who have induced
menopause (most commonly brought about by chemotherapy), we still know very
little about what truly causes these sudden throes of fury. We know they occur with decreases in estrogen
levels, as ovarian follicles (eggs) diminish, but we’ve never connected the
line to how that produces a sense of overheating. The best explanation that I found was from an
April 12, 2012 article from U.S. News and World Report, which appeared to
recognize the importance of the issue since women between ages 44-65 is the
largest demographic in the world. (Maybe
our politicians should take note!)
In this article, they discussed a study of peri-menopausal
women with daily hot flashes. Women wore
a 24-hour heart rate monitor and recorded their hot flashes. During the hot flashes, a decrease in the
parasympathetic regulation of the heart rate occurred. What does this mean? The parasympathetic nervous system is part
of the autonomic nervous system, regulating our heart and breathing rates while
our body is “at rest”. The sympathetic nervous system provides the
adrenaline or surge necessary for “fight or flight”. In other words, our circulatory system, as
it is being regulated by the nervous system, seems to be sending signals to our
brain to cool our body off by increasing our blood supply to the skin, which in
turn causes flushing and sweating. Or, as
Sandra Tsing Loh illustratively describes in her October 2011 article in The
Atlantic, “during
menopause, a woman can feel
like the only way she can continue to exist for 10 more seconds inside her
crawling, burning skin is to walk screaming into the sea—grandly, epically, and
terrifyingly, like a 15-foot-tall Greek tragic figure…”
Despite the sleeplessness, fatigue and annoyance,
I am grateful to endure this change in my life while progressing through
chemotherapy. I’d much rather deal with
this nuisance while I’m already exhausted, so I can take a restorative nap or break
when needed. To assist me, Chris has
happily shared his napping expertise, although I’ve not perfected his rapid
onset and awakening techniques just yet.
Nonetheless, learning to fall back to sleep quickly after awakening from
night sweats can make those 3-4 nighttime awakenings less evident during the
day. But, if you see the bags under my eyes or the "color" in my cheeks, you'll understand why.
I don’t have hot
flashes. I have short, private vacations
in the tropics. ~ Anonymous
