I’ve recently read a number of books that engage with topics of sunlight, darkness and the winter, exploring all the practical implications of the season and the night sky as well as their metaphorical associations. (See also: my review of An Ode to Darkness by Sigri Sandberg.)

Two of these are brand new as of this month; the other came out in paperback late last year and was one of my Christmas gifts.

Under the Stars: A Journey into Light by Matt Gaw (2020)

I very much enjoyed Matt Gaw’s The Pull of the River (2018), a jolly yet reflective travelogue of canoe trips down Britain’s rivers. His follow-up nature book is broader in focus but again rooted in on-the-ground knowledge, chiefly gained through a series of night walks. He travels everywhere from London to Isle of Coll, a Dark Sky Community in Scotland’s Inner Hebrides, to compare the quality of darkness and to ponder the emotions these places elicit at night. Fear of darkness feels innate, while for him the stars are almost overwhelming.

In London and in Bury St Edmunds, where he lives, Gaw observes that cities seem removed from nature and that artificial illumination is causing light pollution that negatively affects flora and fauna. At the beach or in Dartmoor or Scotland, though, being outside at night allowed him to feel “part of the natural world in a way that I rarely have during the day. … To be open to the night, to welcome it, embrace it, rather than shut it out, does bring with it an extra richness. To walk at night has been a night twice lived.”

Whether making a jaunt to a 24-hour supermarket after hearing a tawny owl or awaking to a cow nibbling at his sleeping bag on Coll, Gaw is an entertaining and knowledgeable tour guide through the nature of night. I admire his writing and hope that with this second book he will continue to find the wider audience he deserves. Under the Stars covers a lot of ground in under 200 pages and would be a perfect primer for someone looking forward to the supermoon on March 9th.

A favorite passage:

“Over the horizon of the North Sea comes the moon. First a glow. Then a pale, pinkish cuticle that swells into a weakling light. It continues to rise, an ever-expanding, ever-brightening island, until after only a couple of minutes she tears away from the membrane of water, dripping light onto the earth, shining back at the sunken sun. The birth of the full moon.”

Under the Stars is published by Elliott & Thompson today, February 20th. My thanks to the publisher for the free copy for review.

Chasing the Sun: The new science of sunlight and how it shapes our bodies and minds by Linda Geddes (2019)

Circadian rhythms govern just about every bodily process, from blood pressure to digestion, so even minor changes in our sleep and sunlight exposure can have drastic effects. Like Matthew Walker’s Why We Sleep, this is a book chock-full of facts that should be common sense, yet are more like a body of knowledge we have lost as we have become disconnected from natural human behavioral patterns. We weren’t meant to work nights, or to stay awake for many hours in the glow of artificial light after the sun has gone down on a winter’s day.

Geddes experiments with making do with only candlelight after sunset for several weeks. She also investigates seasonal affective disorder and “circadian lighting,” surveys the history of sunlight as a medical treatment, gives practical advice for minimizing jet lag, and weighs the case for abolishing daylight savings time. Whether you’re a regular reader of popular science or not, you should pick up this concise and highly readable book by a science journalist; it delves into topics that affect us all. It’s one to keep on the shelf and refer to the next time you cross time zones or change your work schedule.

Wintering: How I learned to flourish when life became frozen by Katherine May (2020)

May’s sympathetic memoir considers winter not only as a literal season, but also as an emotional state. Although “depression” could be substituted for “wintering” in most instances, the book gets much metaphorical mileage out of the seasonal reference as she recounts how she attempted to embrace rather than resist the gloom and chill through rituals such as a candlelit St. Lucia service and an early morning solstice gathering at Stonehenge. Wintering alternates travel and research, and mind and body. Cold-water swimming becomes the author’s primary strategy for invigorating a winter-fogged brain and frozen limbs. (My full review will appear in a forthcoming issue of the Times Literary Supplement.)

Wintering was published by Rider Books on February 6th. My thanks to the publisher for the free copy for review.
