How to ruin your ability to make vitamin D3 from sunlight. Blue light and microwave (Wi-Fi, cellular) frequencies disrupt vitamin D3 production by dehydrating us. The isomerization step of vitamin D3 production requires water

Dr. Jack Kruse: "We are a factory that is capable, when we're healthy, of pretty much making everything we need. [...] I have a saying: 'If we're designed to make it, you shouldn't take it.' For an example, I'll give you the easiest one.

"We're designed to make vitamin D on our skin. It makes absolutely no sense to take vitamin D orally, in most cases, with a couple of exceptions. And the reason why is when you take something that your body makes you ruin the feedback mechanism, it's the negative and positive feedback. So in other words, you downgrade your endogenous production. [...] So what's the better plan? The better plan is to understand physically how your body makes vitamin D and then fix that. [...] The key is understanding the physics of the organism, the physics of the cell, and innovating. [...]

"One of the questions I got asked from the medical students yesterday was, 'Why do we have this global pandemic of vitamin D?' And my quick answer to them, which shocked them, was every everybody is dehydrated. Why is that? We live in a blue-lit, microwave world. What do those light frequencies do to cells? They dehydrate us. And it's not hard to understand because anybody who's ever cooked a steak or try to heat it back up the next day in the microwave knows if you don't wrap a paper towel around it, it tastes like shoe leather. Why? Because it gets dehydrated. So the thing is happening to us right here on the planet because of all the things we're doing, like what Adam's got on his head right now. The light frequencies that are around us, in your car, these things chronically dehydrate us.

"When you get dehydrated there's a quantum step in vitamin D3 production called the isomerization step. When you don't have water in your body you cannot make vitamin D. [...] If you are truly a thermodynamic thinking kind of person you need to know a lot more about light and understand how light works, not only with the fuel you put in, but also in the engines that are in your cell."
