Stress and the sympathetic nervous system

People talk about adrenal fatigue: what is it that they mean? And how can we address it?

When we are relaxed, or less stressed, we make more sex hormones and thyroid hormone.

When we are in a crisis, or more stressed, we make more adrenaline and cortisol.

The pain conference I went to at Swedish Hospital took this a step further. They said that chronic pain and PTSD patients are in a high sympathetic nervous system state. The sympathetic nervous system is the fight or flight state. It’s great for emergencies: increases heart rate, dilates air passages in the lungs, dilates pupils, reduces gut mobility, increases blood glucose, and tightens the fascia in the muscles so that you can fight or run. But…. what if you are in a sympathetic nervous system state all the time? Fatigue, decreased sex drive, insomnia and agitated or anxious. And remember the tightened fascia? Muscle pain.

When we are relaxed, the parasympathetic system is in charge. Digesting food, resting, sexual arousal, salivation, lacrimation, urination, and defecation. So saliva, tears, urine, and bowel movements, not to mention digesting food and interest in sex. And muscles relax.

If the sympathetic nervous system is in overdrive, how do we shut it off? I had an interesting conversation with a person with PTSD last week, where he said that he finds that all his muscles are tight when he is watching television. He can consciously relax them.

“Do they stay relaxed?” I asked.

“I don’t know.” he replies, “but my normal is the hyperalert state.”

“Maybe the hyperalert state, the sympathetic state, is what you are used to, rather than being your normal.”

He sat and stared at me. A different idea….

So HOW do we switch over from the sympathetic to the parasympathetic state?

Swedish taught a breathing technique.

Twenty minutes. Six breaths per minute, either 5 seconds in and 5 seconds out, or 6 in and 4 out. Your preference. And they said that after 15 minutes, people switch from the sympathetic to the parasympathetic state.

Does this work for everyone? Is it always at 15 minutes? I don’t know yet. But now I am thinking hard about different ways to switch the sympathetic to parasympathetic.

Meditation.
Slow walking outside.
Rocking: a rocking chair or glider.
Breathing exercises.
Massage: but not for people who fear being touched. One study of a one hour massage showed cortisol dropping by 50% on average in blood levels. That is huge.
Playing: (one site says especially with children and animals. But it also says we are intelligently designed).
Yoga, tai chi, and chi kung.
Whatever relaxes YOU: knitting, singing, working on cars, carving, puttering, soduku, jigsaw puzzles, word searches, making bean pictures or macaroni pictures, coloring…..and I’ll bet the stupid pet photos and videos help too….

My patient took my diagrams and notes written on the exam table paper home. He is thinking about the parasympathetic state: about getting to know it and deliberately exploring it.

I like this picture of Princess Mittens. She looks as if she has her head all turned around. Isn’t that how we get with too much sympathetic and not enough parasympathetic nervous system action?
