Gary Brecka explains how constant fight-or-flight activation suppresses immune function and healing. Nasal breathing triggers rest-and-digest mode while mouth breathing keeps you stressed. Sleep before midnight matters: timing affects immune response and brain repair more than you'd think.
I think the body knows when you're in this constant sympathetic state of stress. People say, well, how is stress related to disease or pathology or autoimmune? Well, it's directly related to our immune system, right?
I'm so glad that you talked about the sympathetic compared to the parasympathetic. One thing that really affects that is breath. Nose is for breathing. Now, when you breathe through your nose with your abdominal muscles, you stimulate your parasympathetic nervous system and your parasympathetic nervous is your peaceful, calming nervous system. But when you're breathing mouth, chest, that stimulates the sympathetic nervous system, and the sympathetic nervous system is your fight and your flight. But also, before midnight, healing accelerates. Lack of sleep has a direct effect not only in the functioning of our brain but also the functioning of our body, the healing of our body, our immune system. It's all connected.
