I recommended someone that was having body clock issues, that especially with a stressful life that they seem to have , they dont seem to leave the sympathetic state, and get into rest and digest mode.
I mentioned to visit someone in hydro therapy, or anyone that can do an Ice Bath. But what else can someone do to " shock their system" to help them reset.
I would like to help but I'm not sure I fully understand your question. You are asking about body clock issues, which I'm assuming to mean circadian rhythm problems, and about the autonomic nervous system, but the two are not really inter-related. Circadian rhythms usually have to do with daylight, temperature, time, etc. while the ans (sns/pns) is more of a mental/physical state.
I don't think you can "shock" someone's system..if the person is under a lot of stress, then they need to figure out ways to reduce the amount of stress or maybe try meditation or other relaxation techniques. I would imagine their circadian rhythm should only be out of sync if they have recently travelled far or perhaps are on a drastically different sleep/wake cycle.
I largely agree with what Kim has said, but would like to add a few questions. What are this person's symptoms that lead you to believe they have a 'body clock' problem? Are they sleeping too little, too much, and/or at the wrong times? Are they lacking energy? Does the person maintain a consistent sleep-wake schedule? Is the person taking any medications that could be affecting their daily rhythms? Are they in the habit of ingesting ordinary substances that are known to affect daily rhythms (e.g., coffee, alcohol, soda, etc.)?
I was instructed many years ago to go to the SEA. As the waves roll in that is the pace of how slow life is meant to be lived. Those waves roll in at a very slow pace. I go when I need to now and just sit and enjoy the rolling tide of the Sea. Luckily for me I live very close to the Gulf of Mexico.
Hey Phillip. Try researching melatonin . . on another level I worked with some Chronic Fatigue people with that issue. Using a cold icepack or showerjet at the same time every morning for a week helped the regulation of the hypothalamus/ptuitary axis by providing a reference point. It was applied to the nape of the neck for one minute. (Barry Sheene, the famous late motorbike champion, used to do it to the max with a cold bath). Regular wake/sleep and mealtimes also helped.
