Questions after reading the Wikipedia article on neurodermatitis:

I read the Wikipedia article on neurodermatitis (https://en.wikipedia.org/wiki/Atopisches_Ekzem) because you get a relatively good overview there. I have put quotation marks around the sections I have questions about. However, I now have a few unanswered questions:

"On the basis of the medical history, an attempt is made to determine possible trigger factors.[19] For this purpose, allergy tests are carried out if necessary.
"
What exactly is meant by these trigger factors, and which are there?

“Other frequently used ointment additives are e.g. B. hemp oil,[21] evening primrose oil, St. John’s wort extract, zinc or dexpanthenol. "
Does anyone have experience with hemp oil and where could you buy something like that?

"How bad is it to take a hot shower because it's relaxing for me? Or do you just have to get used to cold showers?

“Because of the anti-inflammatory and antiseptic effect, wearing silver-containing textiles helps some sufferers. "
Anyone have experience with this?
How can textiles contain silver?

Are there bad and good sunscreens for sensitive skin?
I have read again and again about neurodermatitis training. Should we do such training?

What to do when your body is itchy. Sometimes I don't itch at all and other times it's very strong and everywhere at the same time. What to do if you have such an “itch attack”?

“Sea and thermal water is rich in minerals and salts and has a soothing and soothing effect on the skin. "
What exactly is the difference between normal water and thermal water?

Since I have hay fever and neurodermatitis, should I rather avoid the forest? Depending on the day, I feel it very badly when I'm in the forest. But since I like to go jogging in the forest, I accept that.
