In this groundbreaking guide to maximizing the restorative and regenerative benefits of light, psychologist Karl Ryberg explains how to use different types of light-sun, fire, and even artificial lighting-in order to create ultimate health and a happy mind. Light. It's all around us. Sometimes soothing and reviving, sometimes glaring and disturbing-light deeply affects us. But can we harness it for our own well-being? Like plants, human bodies need quality light in order to survive, regenerate, and thrive. In this fascinating guide to "eating light" psychologist Karl Ryberg shows you how to best use different types of light to feed your brain and body. Discover how your brain and body absorbs light photons in the form of sunshine, fire, and artificial light. With increased use of computers and screens, flickering LED products, and other "junk food" light sources, we have been paying the price with lowered vitality, focus, and flagging health. By intentionally consuming certain types of light with a proper "diet", you can alleviate these issues. Ryberg shows us practical ways to maximize the benefits of light therapy for our own bodies, and how to choose light sources that don't harm the environment. No matter your age, location, or fitness level, Living Light has timely advice on a range of topics, from remedying light starvation or overload to adopting routines to suit your individual needs. Written from a lifetime of research on light and biology, this book provides you with a vital understanding of your body clock, brain function, the importance of color, and much more, all in a clear and accessible manner.
