Apples and Oranges..

A pathogen does what a pathogen does even if you have no immune reaction which is what they look for.

"To use conventional diagnostic tests such as the Western Blot, one has to think in paradoxes: the patient has to be treated with an effective treatment modality first before the patient recovers enough to produce the antibodies, which then are looked for in the test."

**So; in general; low vit D;
How much to blame on the sunscreens??
What other factors are the real offenders,like pufas??**

other variables involved IMO:

- exercise
- determining the difference between toxicity and immune reactions, i.e. differences between toxicity crisis, immune reaction to toxin, immune reaction to pathogen
- whether or not an extreme immune **drop**, like an immune boost, can cause symptomatic flareups appearing to be an immune reaction
- air quality changes and exposure changes, both indoor and outdoor
- who knows what else..

we pretty much all exercise less in the colder months. exercise is your body on super detoxification, elimination, immunity, and "hormone re-adjustment mode"(to higher baseline metabolic rates, including immunity pathways themselves, strength training more so then cardio to BTW). but of course like any oxidizer moderation and "anti"-oxidants and/or electron donning are key..

also lets take into account the origin of catching a **cold**. obviously it seems to be most associated with being exposed to cold weather. so, is this from an immune boost or drop, or a weird combination of both??? i believe colder air might hold more oxygen and negative ions, or overall negative charge, and and we already know a few folks claim ice cold water exposure can do amazing things.
then we have likely immune loss from heat/energy loss..

plus we know chronic stress can make people get sick, and there's little or nothing immunity boosting about Sympathetic over-modulation, i would surmise. so is their symptoms from toxicity and elemination problems, or, an immune reaction/response, from an immunity **drop**
