If you need an alarm clock to wake up each morning, which most of us do, you are likely suffering from social jet lag.
That's a mismatch between your biological clock and your daily schedule.
And according to a new book by science journalist Lynn Peeples, drinking coffee or sleeping in on the weekends won't help you get back on track.
In her new book, the Inner Living in Sync with Our Circadian Rhythms, People's gets into the latest science around our circadian rhythms and their importance in our overall health even beyond the hours of sleep we each night.
Peoples conducted her own experiment first by living for 10 days in an underground bunker 50ft below ground with no sunlight, watches or clocks to better understand the rhythms that guide her from day to day.
In her book, Peoples digs into the latest research about how our internal clocks impact every facet of our lives, how well we do in school, our performance at work, how we interact with people, and even how long we live.
There are even studies that link circadian disruption to cancer, depression, dementia and Alzheimer's.
Lynn Peeples is an MIT Knight Science Journalism Fellow.
She's also a biostatistician and has conducted HIV clinical trials and environmental health studies.
Her writing has appeared in the Guardian, Scientific American, and Nature.
Lynn Peoples, welcome to FRESH air.
Thanks so much for having me on.
Let's just start with this experiment that you did.
