Welcome to the Siim Land Podcast, I'm your host Siim Land, and today we have a YouTube live Q&A session. I answer different kinds of questions about health, fitness and biohacking. Unfortunately, there was a bit of an echo in the live recording for some reason, so I'm gonna apologize for that, but the information itself is pretty good. So, I hope you'll still enjoy this episode.

All right, how's everyone doing?

Welcome back to another live stream. It's been a while, I haven't had a live Q&A in a long time. But yeah, I think we should be good at the moment.

But first, I'll maybe just mention as well that if you aren't following me on Instagram, then make sure you do it as well.

I have like a pretty good content on there as well about the different kinds of topics, like recently I've been doing like this long carousel posts about one topic, like when is information good?

You know, one of the videos was about that. What are the main causes of aging?

How do you nutrient partition the calories you eat into more muscle and less fat? And today I also published a good post about red light and how it affects skin health. So there's actually a lot of benefits to red light when it comes to like acne and wrinkles and stuff like that. So it's actually a pretty good post. Let's just maybe like look at it for a little bit to go through it.

So this kind of red light therapy and light therapy in general has been pioneered for a long time, at least like since the 1903, when Niels, well, he was doing it before that already, this guy from the Faroe Islands, Niels Finnsen, he was doing this kind of light therapy on people and he used different kinds of lights. Some of them were like, you know, red light. Some of them were blue light, bright light, but specific, but in 1903, he got like a Nobel Prize as well for his like, this work that he did. And when it comes to the red light, then he mostly used that for treating smallpox lesions. So there was actually like a ton of different kinds of photos online that you can find about these kinds of people being able to, or he treated them with red light and he helped to basically alleviate a lot of these smallpox and stuff like that, which is, you know, also makes you kind of quite appreciative of modern life, et cetera. Like a smallpox itself isn't like an actual thing anymore. It's very rare. And I think it's mostly exterminated, if that's the correct term. And yeah, like smallpox is pretty crazy itself. So yeah, it's good to have it eradicated.

But why does red light have these positive effects? Well, red light is one part of the visible light that you get from any sources, but mostly from the sunlight. And the red light itself is between 600, 700 nanometers opposed to blue light, which is somewhere around 350 to 500 nanometers. And blue light is the one that is mostly associated with like wakefulness and alertness and daytime. And the red light is more like sunset, sundow, how do you call it? Sunset, yeah. And mostly like relaxing, calming and healing almost, in a sense, because when you're going to bed at night, you're going to sleep, then that's the time when your body is repairing itself the most. And yeah, like the red light is almost like a circadian rhythm signal to the body that tells it, okay, this is the time where you are supposed to start to heal and you're supposed to start to rejuvenate the process for the night. And melatonin gets secreted as well in response to red light a little bit. So yeah, like it's a very important signaling factor to the body when it comes to just the overall health. And in studies, the studies find that the red light has a good effect on wound healing. So it stimulates like energy production in the body and energy mitochondrial function, which then speeds up all kinds of other processes, including wound healing and things like that. Like you lower the inflammation there, you also direct more blood flow into the region that is being stimulated by the red light. And in the process, that just helps to get it over with, start the healing faster. And blood flow is important for healing. Energy production is important for healing and the red light helps with that.
