Benefits of time outdoors for people with arthrofibrosis

In this interview Dr Kayley Usher interviews MedCram co-founder Prof Dr Roger Seheult about the benefits of being outdoors for people with arthrofibrosis as follow up to our previous blog post Light as Medicine. We've listed some highlights and important take-aways from the interview below.

The interview is split into two videos Part 1 and Part 2 and available in the following playlist:

Quotes from Part 1

"If you have oxidative stress that makes the mitochondria not work as efficiently, which causes more reactive oxygen species, which causes even more damage. And believe it or not, what I'm describing to you here, reactive oxygen species and oxidative stress and damage have been implicated in numerous diseases that that are seen in the Western world."

"So infrared light, number one, you cannot see it. Number two, it can penetrate very deeply (into the body)."

"Well, as it turns out, that solution for having melatonin is really something that happens during the day."

"Melatonin is probably one of the most powerful antioxidant substances known to man. So it's sort of the King of kings when it comes to antioxidants and removing oxidative stress."

"What's required (for melatonin production) during the day is exposure to sunlight, and I say sunlight very specifically and not just light because it's specifically near infrared light from the sun."

"So being outside is going gives you not only the benefits of near infrared light, which does not make vitamin D, but also the benefits of ultraviolet B radiation, which does make vitamin D."

"And I've seen pictures from over 100 years ago. Hospitals had like sanatoriums, where they would have the entire ward, they would take them outside and put them in the sun."

"There's been multiple studies that have shown that the more somebody is out in the sun, the less Alzheimer's disease that they have, that whole brain volume, grey brain volume is associated with sun exposure, less multiple sclerosis."

Quotes from Part 2

“So what does that mean for us? That means that getting red light, these sorts of things, can actually help with reducing glucose, improving metabolic health, and reducing oxidative stress.”

“The sun emits all of the wavelengths, so you don't have to worry about (which wavelength is best) if you just get outside, you are going to get all of the wavelengths that your body needs to get.”

“You're not only getting the benefit of these plant chemicals when you are walking outside and getting the sunlight and near infrared and this good package deal, but you're also away from work. You're out in nature.”

“The appropriate response to an invader or an injury is to have a good amount of inflammation to take care of the issue, and then for it to turn off.”

“The type of melatonin that you need, though, is the type of melatonin that is stimulated by near infrared radiation directly in your mitochondria. That type of melatonin is not going to be supplemented by you taking a pill of melatonin.”

“If you want the benefit of near infrared light and you're going outside, put a broad rim hat on. Cover up. Wear long sleeves and if you want wear a sunscreen. None of those things are going to prevent near infrared getting into your body.”

“It's a very, very good practice to get up in the morning when the sun is just rising and get that experience of that sunlight.”

“If you have difficulty falling asleep at night, or you have insomnia, one of the things that I would highly recommend doing is #1 expose your eyes to bright light in in the morning when the sun is coming up and #2 don't eat 3 hours before lights out.”
