Why is it difficult to fall asleep during perimenopause?

A balanced hormonal cycle was one part of what made sleeping easier when you were younger. But now that your hormones have begun to shift, drifting off to sleep and staying asleep isn’t as easy as it once was. You may find yourself restless and wide awake in the middle of the night and, if you’re having night sweats, a close relative of hot flashes, even if you do get to sleep, you can wake up so clammy and  chilled that you need to get out of bed, change bed clothes or sheets.

The first big biological shift hits around 40 (though it can happen anywhere from 40 to 55) when the ovaries start slowing down production of estrogen and progesterone, both of which are hormones that promote sleep. This is when the simple act of falling asleep may start to seem like a major life achievement.
