Why is my symptoms more intense after
exposure to Light & / or Vitamin D ?

People with significant Th1 inflammatory illnesses are often sun and bright light sensitive. Sun and bright light affects their disease symptoms, even if they haven't been aware of this before. ...

There is no typical length of time between excess sun exposure and a symptom flare. Some will feel the effects within an hour or two while others may not experience an increase in symptoms for a day or longer.

Symptoms in response to sun light exposure are not due to an increase in antibiotic potency or an increase in immunopathology. They are caused by a rapid increase in 1,25-D and the hormonal shift this causes.

Light falling on the eyes may cause neurological symptoms such as fatigue, iriitability, aggressiveness, lack of concentration, brain fog, photosensitivity, transient loss of memory, mood swings, confusion, anxiety, anger, neurosis and even psychotic symptoms.

Immunopathology or the reaction from killing bacteria, causes a rise in 1,25D (which is an add on to the light effect)

Hypersensitivities to sunlight usually occur only during the first 1-2 years of recovery and primarily in folks with extensive Th1 inflammation. We do not currently believe that exposure to sunlight, even though it raises the level of 1,25-D (and may raise the level of 25-D), causes a significant retardation of the bacterial killing or inhibits overall long-term healing, as long as the patient’s level of 25-D is maintained below 12ng/ml.

Photosensitivity symptoms can occur within minutes and up to 3 days after exposure. Those pursuing the MP who expose themselves to the outdoors or to natural and fluorescent light indoors will soon know if they can tolerate light, and to what degree, based on their symptoms. Therefore, it is important that folks learn to differentiate between immunopathology symptoms and their photosensitivity symptoms because reducing light exposure may be necessary for some to control photosensitivity symptoms.

... every time I went out in the sun or had anything with high D I would go hyperthyroid (with the full range of those symptoms), and when it settled down and converted again, would go hypothyroid (with about half of those).

"The short-term consequences of Th1s not wearing adequate eye protection will be an increase in neurological symptoms caused by stimulation of the amygdalla in the brain. These neurological symptoms include fatigue, irritability, aggressiveness, lack of concentration, brain fog, photosensitivity, transient loss of memory, mood swings, confusion, anxiety, anger, neurosis and even psychosis."
