Are our bodies resilient, meaning that if you've worked for years and years on a night shift and then you've done all of this damage, your circadian rhythm is out of whack, and then now you're back with the living, can you get that time back on the damage that you've done to your body?

Our guest today is author and science journalist Lynn Peoples. We'll be right back after a short break. This is Fresh Air.

You write about how hormones impact so much of our circadian rhythms. So what do we see in men versus women?

I mean, any woman who has gone through menopause knows that for so many, there's this bewitching hour when sleep eludes. I think I've been reading research about how 3 to 5 a.m. is like a really important time for REM sleep, but it's also where it's the biggest disruption for menopausal women in their sleep cycle.

Is that something that humans, just women, have to live with, or is there a way through our understanding of our circadian rhythms that we can get that REM sleep that we need during that time period in our lives?

Lynn, you write about scientists at the University of Pittsburgh who found many of the rhythms that are dominant in most humans were missing or altered in the brains of patients with schizophrenia. And that just made me wonder. It's so fascinating, that research. Is there a correlation between some mental health disorders and the differences in rhythms?

Lynn Peebles, this was such a fascinating conversation. Thank you so much. Thank you so much. Lynn Peebles' new book is The Inner Clock, Living in Sync with Our Circadian Rhythms. Coming up, TV critic David Bianculli reviews two new comedy series, one about a woman whose ex-boyfriends begin dying off, and another about a military colonel who's forced to take command from his estranged daughter.
