Light shapes life - how is it shaping yours?
A few years ago, I started to read about the powerful effects of light on life. Everyone today is worried about fake food. If e = mc^2, then light = food. If fake food is a problem, then so is fake light.
I created this challenge to show people how powerfully light shapes life, and how bad fake light is for life. This blog post is just the first few pages of a much larger ebook, which you can download here.
What is real light? We are optimized for sunlight, which contains 42% infrared and a large proportion of red light. Modern LED and fluorescent lights are deficient in these wavelengths. And these wavelengths are critical for life.
Red and infrared light improve energy generation in our mitochondria, assisting in wound healing and resistance to disease. Thus, red and infrared lights are being used in everything from sports medicine to traumatic brain injury to stroke.
Modern lighting has eliminated red and infrared light to save money and...
We go to great lengths to escape the cold. We insulate our houses with space-age technology, we have remote starters for our cars, we have seat warmers, cup warmers, and even disposable hand warmers. And with good reason. The cold can kill in a matter of hours. We cannot easily create heat in the dark, cold winters that descend upon so much of planet earth, and yet we cannot all live in the tropics, where it is pleasantly warm year-round.
The temperature of the earth is determined by the amount of sunlight that reaches the earth’s surface. During the Arctic winter, the north pole tilts away from the sun. The day is short and sunlight must traverse more and more of the earth’s atmosphere in order to reach the earth’s surface. This scatters light away. The cold temperatures also coincide with storms and cloudy weather, which reflect more light back to space. The result is the incredible cold of the Arctic winter.
The cold can kill in a matter of hours, which is why...
