Libro: THE LIGHT DOCTOR: Using Light to Boost Health, Improve Sleep, and Live Longer

"This book terrified me, in the best way. Dr. Moore-Ede is doing cutting-edge work to change the way we think about light and how it affects us." - Penguin Life

"I was so impressed with his detailed yet thoroughly comprehensible explanations and expert advice! I’ll definitely be changing some of my lightbulbs ASAP!" – Simon Element

The light we see is as important for our health as the food we eat, the water we drink, and the air we breathe. For most of human existence, our ancestors lived with the natural 24-hour light-dark cycle, spending each day in natural daylight and sleeping in the dark at night. But since the widespread introduction of electric light, more than 90% of our time is spent indoors, under unhealthful and human-unfriendly electric light, which disrupts our circadian clocks and greatly increases the risk of cancer, obesity, diabetes, heart disease, and hundreds of other diseases.

Today’s LED fixtures, light bulbs, and screens are designed to produce cheap light with little regard for human health. Like DDT and asbestos, they are dangerously flawed technologies. THE LIGHT DOCTOR reveals extensive scientific evidence establishing the risks of blue-rich artificial light at night. Furthermore, it provides the practical information you need to counteract these risks at home, and in workplaces, schools, hospitals, and senior care facilities.

"I had no idea that artificial lights posed so many health risks, beyond the disruption of sleep. And Dr. Moore-Ede is clearly the leading authority on this topic." – Spark

"As someone who sits under fluorescent office lights all week, it made me question my life choices! The author does terrific job." – Tarcher Perigree

Here is how to find and install healthy light bulbs and fixtures for both residential and commercial spaces, how to obtain the lights you need for evening and night use versus daytime, and how to obtain energy-efficient light that is also safe and healthy. You will also learn which outdoor lights to install to avoid harmful effects on wildlife, another inadvertent consequence of the LED revolution.
