Chasing the Sun by Linda Geddes

Chasing the Sun (Wellcome Collection)

by Linda Geddes

'A sparkling and illuminating study, one of those rare books that could genuinely improve your life' James McConnachie, Sunday Times


Since the dawn of time, humans have worshipped the sun. And with good reason. Our biology is set up to work in partnership with the sun. From our sleep cycles to our immune systems and our mental health, access to sunlight is crucial for living a happy and fulfilling life. New research suggests that our sun exposure over a lifetime - even before we were born - may shape our risk of developing a range of different illnesses, from depression to diabetes.

Bursting with cutting-edge science and eye-opening advice, Chasing the Sun explores the extraordinary significance of sunlight. - from ancient solstice celebrations to modern sleep labs, and from the unexpected health benefits of sun exposure to what the Amish know about sleep that the rest of us don't.

As more of us move into light-polluted cities, spending our days in dim offices and our evenings watching brightly lit screens, we are in danger of losing something vital: our connection to the star that gave us life. It's a loss that could have far-reaching consequences that we're only just beginning to grasp.

Decent Exploration Of The Topic. A couple of caveats to this review up front: This book was released in 2019, and I've read at least a handful of books on the same general topic of human circadian rhythms both before and since. I also read it via Audible, so I have no way of knowing if its documentation is adequate or lacking. These caveats noted, to me this book was more a decent introduction to the general topic than a truly in depth or ground breaking look at it. Most of the things it covered were things I was already generally aware of and even knew a bit of the specifics of due to those other books. So to me, there truly wasn't much "new science" here at all. And yet, the book was very much approachable and enjoyable, and indeed seemed great for someone less read in the subject at hand. Geddes herself reads the Audible version, and it is quite clear she both knows her subject well and is genuinely passionate about it, so those are definite bonuses in my take on the book. Overall a truly solid introduction to the topics at hand, told in a very approachable manner even for those less familiar with them. Very much recommended.
