There is something similar as testosterone levels decline after 40, except I understand it’s typically a much less noticable process since it’s a gradual decline vs estrogen levels just tanking. I don’t know if that ultimately effects sleep, but other changes like activity, stress, diet and other habits will.

I’ve been perimenopausal for several years now and the worst symptom I’ve experienced is the sleep disruption. Last week I basically stopped sleeping, so I’m on hormones now. There’s a slight relief, but at least I’m getting 6 very interrupted hours which is better than last week!

Worse than that. I’m 54, but I swear “around 30 years ago” was somewhere around the early 80’s when I was growing up. Math may argue, but my heart says it’s true no matter how much my knees deny.
