Hot Flashes and Killer Whales: The Evolutionary Advantage of Menopause

The patriarchy thinks menopause is a problem. A new book is making waves with the argument that 鈥渢he change鈥� has value for our species and the women who go through it.

It鈥檚 usual to say that women 鈥渟tart鈥� menopause. But for Darcey Steinke, menopause was more like being engulfed: 鈥淚 wake, heart thwacking, as heat flows up from my stomach, courses behind my face, and radiates out through the top of my head. … I throw off my covers and feel, in the first pocket of spooky quiet, that flames are burning from my inner organs up into my muscles toward the skin. I鈥檇 run away, but how does one flee one鈥檚 own body?鈥� Hot flashes, night sweats, and insomnia are well-known symptoms of the decrease in estrogen at menopause. Less discussed are the 鈥渁uras鈥� Steinke had before the flashes, an experience shared by many of the women she interviewed for her new book, Flash Count Diary: Menopause and the Vindication of Natural Life. Some described a sudden feeling of foreboding or free fall before a hot flash. Steinke described a stillness and a sensation of being 鈥渙utside continuous conventional reality.鈥� Rather than dismiss these moments of changed perception as just another symptom, Steinke allowed herself to consider them. She began keeping a record of her hot flashes鈥攚hen they occurred and what they felt like. But she also began researching and writing about menopause as a threshold before the next phase of life鈥攗nknown, but anticipated. The end result is her paradigm-shifting book. It鈥檚 a literary memoir that takes in anger, sex, marriage, gender transition, parenting, death, philosophy, spirituality and killer whales (yes, really) along the way. It鈥檚 lucid, lyrical, and sometimes funny. But unlike so much of popular culture, Steinke鈥檚 humor is never at the expense of women over 50.

鈥淚 found flashes to be desperate, uncomfortable, sometimes even sublime, but never funny,鈥� she writes. The book is getting quite a bit of media attention, and has helped create a space for talking and writing about menopause from a new perspective. 鈥淭here鈥檚 so little that鈥檚 good that鈥檚 written about it,鈥� Steinke says of the menopause books on offer, which she says almost exclusively consist of advice on how to overcome symptoms with self-care, herbal remedies, or hormone therapy (otherwise known as 鈥淗T鈥�). While she found Dr. Christiana Northrop鈥檚 bestseller The Wisdom of Menopause marginally helpful, something was still missing. 鈥淚 wanted a more personal view,鈥� she says. 鈥淚 wanted to see myself reflected somewhere. And I could never find that.鈥� A great deal of advice from the menopause industry homes in on sex: whether menopausal women can still do it, and whether they鈥檙e still desirable enough that anybody would want to do it with them. Taking HT can delay or lessen symptoms like hot flashes, diminished libido, and the thinning of vaginal membrane, but that comes with a small increased risk of cancer.

滨苍听Flash Count Diary, Steinke speculates that there might be something of value on the other side of the hormonal withdrawal that is menopause: 鈥淪ome scientists say menopause is triggered when the number of viable eggs in the ovaries is too low; others admit they don鈥檛 know why egg maturation stops and hormones diminish. Without hormones, my body changes again, just as it did in adolescence when I was flooded with estrogen and began to menstruate. While menstruation still carries stigma in our culture鈥攚e are 鈥榦n the rag鈥� and considered unstable because of fluctuating hormones鈥攖he fertile years of a woman鈥檚 life are also considered her most essential. Menopause, on the other hand, is disparaged, even considered shameful. No one proposes we eliminate childhood, adolescence, or adulthood from the female life cycle. Only menopause is considered something to be cured and reversed, done away with completely.鈥� The natural world offers unexpected sources of inspiration. After another sleepless night of hot flashes, Steinke reads an article about killer whales, one of the few mammals other than humans that go through menopause. For most female mammals, fertility doesn鈥檛 stop completely, just dwindles until they die. But orcas鈥攖he cetaceans known as 鈥渒iller whales鈥濃€攇o through menopause and have a long post-reproductive life, like humans.

Research indicates that menopause had an evolutionary advantage for orcas.

Whale researchers know this thanks to the Southern Resident Orcas, an endangered group now numbering 75 living in the Salish Sea close to dense human populations in Canada and Washington state. Their location is convenient for research but not so good for the Southern Residents, a cluster of related pods, or families, with big, convoluted brains, and what researchers describe as a distinct 鈥渄ialect鈥� of whale calls and a 鈥渃ulture鈥� of learned behavior. Orcas also have strong social relationships, and their pods are led by post-menopausal females. Research indicates that menopause had an evolutionary advantage for orcas, because having post-reproductive females around to help with care and feeding increased the life chances of the young. In the study of human evolution, this is 鈥渢he grandmother hypothesis鈥濃€攖he theory that post-menopausal women in hunter-gatherer societies were good for the group as a whole. Freed from the work of bearing their own children, they helped care for and feed their grandchildren, increasing the likelihood of their survival. The next generation carried their genes, and the menopause advantage was passed on. The wise historians of the world鈥檚 few remaining hunter-gatherer communities, Steinke says, are very old ladies who know from experience where to find food in times of scarcity, where that well was and where to dig, and what young couples need to do to get along.

In Flash Count Diary, the Southern Resident Orcas become Steinke鈥檚 long-distance menopause companions. From her study in Brooklyn, she livestreams an underwater whale research mic in the Salish Sea and listens for their vocalizations. She dreams about them. If comparisons between women and orcas feel like overreach, consider that Steinke is not the first to make them. One of her beloved orcas, a 6-year-old female snatched in the great Puget Sound whale capture of 1970 and flown to Florida, was placed in a pool at Miami鈥檚 Seaquarium with a much older male. Her new owners cleverly named her 鈥淟olita,鈥� after the Nabokov novel about a pubescent girl held captive by her predatory stepfather. Steinke鈥檚 fascination takes her from a protest at Lolita鈥檚 too-small pool in Florida to the Pacific Northwest, home to free female orcas, including the 100-year-old J2, or 鈥淕ranny,鈥� the Southern Residents鈥� post-menopausal matriarchal leader of the pod. There, on a kayaking trip, Steinke has the good luck to be approached by J2 and looks into the eye of a whale. It鈥檚 the culmination of her menopausal journey, a transcendent experience of wonder and mystery. If that sounds a little woo-woo, be assured that the writer鈥檚 craft, buoyed by research, guides readers thoughtfully to her orca encounter.

Steinke is aware that 鈥渨hat orcas and menopausal women have in common鈥� is a tough elevator pitch. 鈥淭he publishing industry was like: 鈥楧on鈥檛 talk too much about the orcas until way after the book comes out,鈥欌€� she says with a laugh. Steinke concedes her book is unusual. 鈥淭his is one of the weirdest books I鈥檝e ever written,鈥� she says. But her choice to let the narrative go where her menopausal quest takes her opens up radical new possibilities for the reader. As it stands, there鈥檚 no way to know what menopause might be like when not viewed through our culture鈥檚 patriarchal lens. But Steinke would like to see a cultural reframing of menopause. Along with that, she鈥檚 considered a new name for the process鈥攁 rebranding, as it were. 鈥淚 have thought about this a lot, in part because I had to say 鈥榤enopause鈥� so many times in my book,鈥� Steinke says. 鈥淚 have a list of words I could use medically. I looked up what it was called in other cultures.鈥� But she says she still hasn鈥檛 found a term that feels right. The thing about menopause, says Steinke, 鈥渋s there鈥檚 real struggle, but there鈥檚 also real gain. It鈥檚 a paradox, like all good things in life鈥攍ike parenting, like sex, like everything. There are bad parts, but there are good parts. The part that鈥檚 kind of lost right now is鈥攎aybe it means we can be more free.鈥�
