The Dangers of Exercise (ex Death) ~ Dr. Eric Berg

So exercise is a type of, uh, movement in your body that has a unique intensity to it, a duration to it, a recovery to it, and a frequency to it, and there's a million different types of exercises based on these four variables, okay? But exercise can be a positive or a negative stress depending on th- these variables right here.

And I'm talking about a positive stress where it causes your body to adapt to become stronger, uh, versus a negative stress which, which breaks down your body and then you don't recover, and you have injuries, and you have other problems, which I'm gonna get to.

So the first thing I wanna talk about, and I'm gonna put these research studies down below because I just went through a deep dive into high-intensity exercise and I found some interesting things, okay, I wanna share with you.

Um, apparently when you do prolonged moderate to high-intensity exercise can actually lower your immune system, okay? At least temporarily.

So apparently moderate to intense exercise can act as an immunosuppressive activity, okay? Because it can impair your T cells because it's a type of stress.

All it takes to lower your immune system is one intense exercise bout, and that lowering of the immune system can last for days.

Also, when you have this sustained high level intense exercise, you actually increase your risk of viral infections, especially in the lungs.
