Dr. Jack Kruse: "I think the one thing I'd like all of you to do, the best decentralized health advice […] is never miss a sunrise the rest of your life. If you do that, you make that decision, that is the single best health decision that you could ever make."
Mike Maher: "So staring at the sunrise, watching the sun come up?"
Dr. Jack Kruse: "You just have to be outside when the sun rises, because what that does, it kicks on your circadian clock mechanism. In other words, the brain becomes much more accurate in sensing light and dark. That's the first step to avoiding the NHS. It's the first step to avoid bad thinking."
Mike Maher: "[…] Here in the UK it's very cloudy sometimes in the morning. […]"
Dr. Jack Kruse: "You're still getting it through the clouds. The clock in your eye is called the suprachiasmatic nucleus. It's an optical lattice clock. It works by light. It senses the color temperature right away. It knows from dark to light what happens, and that starts the whole process of all the circadian clock chains in you. That controls all the biochemistry from that level below. In other words, if you don't get that message, you've created absolute chaos in the biochemical pathways below, and you will never get better."
