Why get SOME exercise?
We make lactic acid when we exercise which looks to help DILATE our arteries to deliver more nutrients - including oxygen - to all our cells.
Too much exercise (very strenuous for too long) however, RAISES cortisol. That is NOT GOOD.
(Music to my ears...I don't have to run marathons, but just get off my behind.)
Catch this:
"Compared with metallic stents, poly-l-
lactic acid
(PLLA) stents are biodegradable and can deliver drugs locally."
Stents to temporarily keep a cardiac artery open via lactic acid until it heals and then dissolve? Wow.
Now...it looks like the BEST way to dilate our arteries is producing lactic acid, but there are other things that can cause our arteries to dilate too. Certain diuretics, calcium channel blocking drugs, nitroglycerine patches, even Viagra, but all of these man-made concoctions aren't ``perfect''.
This is interesting!
Dietary Nitrate and Nitrite to Increase Nitric Oxide in Patients With Coronary Artery Disease
This study is currently recruiting patients. Verified by National Institutes of Health Clinical Center (CC) September 2006
Nitrates May Explain Success of Blood-Pressure Diet
Small Swedish study suggests leafy vegetables could be source of nutrient
By Ed Edelson HealthDay Reporter
WEDNESDAY, Dec. 27 (HealthDay News) -- A small Swedish study could help explain why the U.S. government-recommended DASH diet helps fight high blood pressure.
DASH -- Dietary Approaches to Stop Hypertension -- recommends eating lots of vegetables and fruits.
The Swedish study indicates that the nitrates in
foods such as spinach, beet root and lettuce spur production in the body of nitric oxide, a molecule that relaxes blood vessels.
"What this study suggests is that the well-known beneficial effects of vegetables on cardiovascular disease may at least partly depend on nitrate," said Dr. Eddie Weitzberg, professor of anesthesiology and intensive care at the Karolinska Institute in Stockholm, and a leader of the study.
Weitzberg and his colleagues had 17 young adults alternately take dietary supplements of sodium nitrate or a placebo, an inactive substance.
There was no reduction in systolic blood pressure (the higher number of a 120/80 reading) when they took the nitrate, but a 3.7-point reduction in diastolic pressure (the lower number) when they did.
"This reduction is in the same magnitude as in the cited DASH study, where those subjects were put on a fruit and vegetable diet for 11 weeks," Weitzberg noted.
The findings are published in the Dec. 28 issue of the New England Journal of Medicine.
The study suggests a new pathway for nitric oxide production in the body, Weitzberg said.
"Ingested nitrate is reduced by oral, commensal, bacteria to nitrite, which can further be reduced to nitric oxide," he explained.
It's too early to recommend nitrate supplements, Weitzberg said. "One should be extremely cautious to draw strong conclusions from our small trial, since we have not yet investigated if the observed effects are withstanding after a longer period of dietary nitrate," he said.
And nitrate is considered "a substance that should be avoided or at least reduced in our drinking water and food," Weitzberg noted, because it is believed to increase the risk of a rare blood condition, methemoglobulinemia, and perhaps of cancer.
"Everyone has been asking why this [the DASH] diet worked," said Dr. Steven Nissen, chairman of cardiovascular medicine at the Cleveland Clinic, adding that the study does provide evidence for the possible effect of the sodium nitrate in green, leafy vegetables.
But Nissen was quick with a caveat -- there isn't all that much nitrate in those vegetables. "Too get as much nitrate as was given in the study, you would have to eat about half a pound of spinach," he said.
"As a practical issue, it's hard to ingest 250 grams of nitrate-rich foods."Weitzberg said research on nitrates and high blood pressure will continue at the Karolinska Institute, in part because the researchers aren't sure about the mechanism of the nitrate effect.
"It is not very easy to unravel the exact underlying mechanisms," he said. "We are naturally planning to look into this more deeply.

Mom was right...eat your spinach, it's good for you!
Note: BP readings can be simply explained: 120/80 is healthy. The top number represents the pressure of the blood flowing thru the arteries when your heart is pumping blood thru the vessels (heart contracts and forces blood flow) and the bottom number represents the pressure in the arteries when the heart is at rest (heart pauses to rest).
Now many believe the bottom number is more indicative of damage to the arteries...they are clogged with placque. When narrow, it takes more pressure to keep the blood flowing even when the heart is "resting"/taking a break.
Naturally, in most instances, both numbers go up, but it appears the bottom number is a more reliable indication of the state of our arteries...have they begun to "harden".
Placque is kinda jagged and if a piece breaks off or if blood collects and coagulates along these areas and breaks off = blood clot. Depending on WHERE it happens, which vessels = heart attack or stroke.
P.S. Isn't THIS interesting:
Vaccine. 2005 Mar 7;23(15):1875-80. Plant based HIV-1 vaccine candidate: Tat protein produced in spinach.
However, I remember reading that vitamin C prevents the conversion of nitrates to nitrites. And if you are "allergic" to bacon, drink some orange juice FIRST. Add an egg and you have "breakfast". ;-)
Once again...some nitrates -> nitrites are good (need some N bond to O), but too much not good?
Red tide...nitrogen spill off into the ocean. Algae gobble up nitrogen and deplete the sea of oxygen and the fish die. It takes about 7 years for the ocean to "rebalance". Trivia. I live where this is a problem. We cut down mangrove trees which would prevent the nitrogen run-off in order to get a better view from our beach front homes...
We need nitrogen to make proteins. Plants take it up (present in the air), animals eat plants and bingo we eat both and have nitrogen.
Now too many nitrates converting to nitrites which grab onto oxygen (less oxygen) isn't good, but there is a stop-gap...vitamin C. Unfortunately humans do not MAKE vitamin C, but other animals do.
Is THIS the key...or one of them?
Vitamin C levels are impacted by zinc and copper levels. Once again...the nutrients all work TOGETHER...so be careful.
Ancora Imparo!

Also, exercise (even mild exercise, I've heard) helps your lymph system work more efficiency.

Unfortunately, I'm not in this situation. I'm hoping it's only because I'm in the beginning of treatment and feel so horrible compared to before.
Although, my head does seem to be getting better.
I do play on getting back to working out and exercise at the first possible moment.
It is definitely good for you.

I had a really hard time getting myself to exercise, until I realized that just walking (ie nothing as complicated as making it to the gym, or jogging, or anything) 'counted' at the stage my body was at. Even short walks around the block was better than spending all day at home. If you can manage that, of course.
-------------------- Symptom Free!!! Thank you all!!!!
Are you employed? Or do you just type fast and your head is never fogged?
I have been doing some TiChi exercises, the ones where I stand and twist my upper body and let my arms swing.
This is good for cleaning out the lymph nodes. I like the way it feels too. I try to do this every 2 hours or so.
I try to use the Nordic Track every third day or so and get a good sweat going.
When my body is cooperating I feel great afterwards. This has happen since I started the salt/C.
My ability to use the NT has improved greatly in the past 2 years.
Back then IF I pushed myself it would take me at least a week to recover. It was so scary and slow going.
That was a really hard time in my life.
I thought that I would never start to recover.
I had to start very slow to exercise. I also bounced on a trapoline.
At that time I was not taking anything to kill LD or co-infects BUT I was eating really well and I think my "alkalined body" was getting rid of stuff.
Maybe that hydrogen producing "thing" that you talked about.

Thanks Marnie
Is it the iron in spinach?
I have trouble with excercise. If I do too much it can bring on many problems - too little when I am in my exhausted mode feeds the problem. My mantra for lyme & excercise has been baby steps.
I recently found a song that get my blood going and makes me want to dance. I put it on repeat & just dance in place. UT's "Mysterious Ways"
When I am tired I just bounce up & down sitting down too, maybe wave my arms a little. Figure its good for my lymph system.
I guess if you can find a song that gets you wanting to dance that's a step.
