I love sun. I sit in it every morning, unless it's raining. And I mean sun outside of a window, because the window does filter some of the light you want. Now, it's not just midday sun. This is something I want to be clear about. Number one, you have different spectrums of light in the morning, in midday, and in the evening. You're going to get more of the yellow, orange, some red as well in the early morning, like if you get up when there's the dawn song of the birds and it's just coming up, and that you really want. It's important to get it in the evening as well. It's also in the red and orange. In the midday, you have a lot of blue light spectrum, but getting the three parts of the clues into your body for each section of the day, early morning is best if you get up early, midday, and then evening, sunset, for example, then that actually triggers off a lot of hormonal responses in your body for your health and well-being. So, like I said, they are different spectrums. Also, if you get underneath a tree in the leaves, you're going to get a far-red light, different spectrum of light. These are frequencies that's healing. People buy all kinds of contraptions to get the far-red light. Think about it. Well, go sit under a tree. So yes, you get the oxygen and all, and it's cooling and so forth, but you get the far-red light. So morning, midday, and evening. Now, the lighter your skin is, the less time you have to spend there. The darker your skin is, the more time you have to spend there. It's said that somebody who's really, really white, like an Englishman, the British, then they're 15 minutes a day, so that'd be five, five, and five. That's minimum. But then, of course, somebody who's a dark-skinned African, for example, is going to have to spend more time. The amount of melanin , the more you have, the slower the vitamin D absorption is. Now, speaking of vitamin D supplements, that's a whole thing that I recommend you look into because cholecalciferol basically comes from a rock crushed, and it is now used in some of the forms of rodent poison. Essentially, what it does is that it pulls calcium out of the bones and puts it into the blood, which is why when you take that particular supplement, you're going to show, and you get a blood test, and say you show you're high in vitamin D, the problem is the calcium is clogging up in your blood veins. So it's a very different thing, and it kills the rats. You have to put out water, and they go drink a bunch of water because it makes them thirsty, and then they clot up and die, essentially. So I recommend checking that out because it's a thing.
