Speaker 0 asks: Should we stop wearing sunglasses?
Speaker 1 responds: Yes. Except we should be wearing them indoors and at night, not outdoors during the day. When you wear sunglasses outdoors, they block the UV, and that's kind of what most people wear them for. Things are bright. Well, reason things are too bright for most people is because they don't get out at dawn to see the sunrise. And if they did, their eyes would adjust to the sun and they wouldn't need sunglasses. We've been told forever from optometrists and doctors that UV is bad for the eyes. And in fact, our eyes have receptors to read the ultraviolet light. And when we cover them with sunglasses, we cannot read how much UV is in the sun, and so we get sunburned.
Speaker 0 asks: So you are an expert in all things circadian rhythm and light diet. So what time are you waking up, and what time are you going to bed?
Speaker 1 answers: So this eight hours of sleep a night, I think is bull. I wake up with the sun. I actually need to sleep less in the summer and more in the winter, and that's how we're biologically designed. We are a light poisoned population. The light that we're exposed to is highly intense in the blue color of light. There's no infrared, almost zero red light, very little yellow, and a ton of blue light. Blue light in itself is not bad, but blue light becomes toxic when we're exposed to too much of it. It messes with our circadian rhythm. It is actually associated with cancer, heart disease, diabetes, and obesity if we see it after sunset, and macular degeneration during the day because we have so much of it hitting our eyes causing free radicals.
