Linda Geddes’s book has changed the way I relate to the sun. After reading it I make sure I spend more of my days getting a high level of sunlight exposure because of its role in regulating my circadian rhythms, improving my mood and shielding myself from diseases such as rickets and multiple sclerosis. nessuna recensione | aggiungi una recensione
Our biology is set up to work in partnership with the sun. Little wonder then that humans have long worshipped and revered our nearest star: life itself arose on earth because its relationship with the sun was a special one, and that relationship still affects us well into the era of electric lighting, indoor workdays, and vitamin D supplements. What are we losing when we sever this ancient biological tie to the sun by spending more and more time inside during the day and surrounded by screens at night? Informed by cutting-edge scientific research and sparkling with memorable characters-from the modern druids who worship at Stonehenge each solstice to the Amish farmers who may have the right idea about healthy sleep patterns-Linda Geddes's Chasing the Sun analyzes all aspects of our relationship to the sun. The fascinating stories, innovative science, and unique perspectives in this book make it clear that the ancients were right to put the sun at the center of our world and that it is crucial that we remember this bond as we shape our lives today.

As the sun has been a central part of almost all the Earth’s inhabitants, lots of creatures have evolved in tandem with it, including us. Research has shown that the sun is key to our mental well being, sleep, immune systems and circadian rhythms. Too much sun is bad for us as it can cause skin cancers but then so is too little, those that rarely see the sun do not generate enough vitamin D that is essential for their health.
One of the biggest disrupters to our health in the modern day is artificial light. Ever since the light bulb was invented, cheap affordable light has been available to all so we have retreated indoors turning pallid in the glow of the modern screens. Office lighting is a good example. The output from the ceilings lights is fairly poor, you only get a fraction of light, around 200 to 300 lux, which is nothing when you compare it to the amount light on a bright day which can reach around 100,000 lux. All of these effects are cumulative, and if you live in northern Europe, then you are much worse off in winter because of the very short days.
I liked this book a lot, it does what a good popular science book should do, gives you a good overview of the subject and touches on lots of different subjects without becoming too academic. On certain elements, for example, on our body clocks and how to improve lighting for those on shift work, in particular, Geddes explores them in a little more depth. Worth reading. ( )
