 +<blockquote>Paul,  
 +I was thinking you should probably add a stronger statement to the KB  https://mpkb.org/home/lifestyle/light/skin_protection#zinc_oxide  based on what Trevor said. 
 +  
 +-- basically that we now strongly discourage the use of ketonconazole due to its effects on the P450 enzyme system as well as other effects. 
 +  
 +Joyce 
 + 
 +*** 
 +Hi Trevor, 
 +I realized due to being too busy I had not finished with this issue.  I hadn't been thinking about it until Joyful brought the recent sunscreen discussion to my attention. 
 +  
 +Were discussing the sunscreen threads that I posted in the moderators forum and was about to put in a section where people could see them back in mid November. 
 +  
 +Your comments are below and in response to them: 
 +  
 +I added a statement about ketoconazole cream and the P450 system. 
 +  
 +I replaced the statement about 400 IU D that you objected to with this: 
 +  
 +The symptoms I experienced were identical to what I got from increased IP due to antibiotics. 
 +  
 +So, if that is alright, I will move these several posts to a forum where everyone can see them, since now, the sunscreen overview is mentioned in the kb but the link doesn't work due to it being in an archived forum. 
 +  
 +Joyful, which thread did you think these should go into?  I thought that it should be one everyone could see? 
 +  
 +Joyce 
 + 
 + 
 +*** 
 + 
 +Well, if you put my disclaimer about ketoconazole right at the beginning of where you start talking about it then I think people are more likely to see it. And add the interference with the key P450 enzymes too. Remember that ketoconazole was banned from internal use after it was found to be toxic. Incidentally, I also have reservations about zinc, you may recall. 
 + 
 +I am not trying to 'buy an argument' but just making sure we document things exactly correctly. 
 + 
 +DeLuca did not find quantities of 25-D being expressed. He most certainly would have quoted Holick if he had found production. Do you want to hang our science on a 1980 Holick paper? To be honest, I haven't had time to re-read either paper - working on abstracts for two conferences at the moment. Tomorrow may be a better time for me. 
 + 
 +..Trevor..

 +Trevor, 
 +  
 +I am shortly planning to post what I have just posted in the moderator thread in the General Discussion thread. 
 +  
 +Joyful and Paul and I agreed this was probably the best way to handle the situation with that thread I had started and linking to it in the KB. 
 +  
 +Then, we will link to these posts in the KB.  One of the posts has a link to the discussion thread that I started where people share experiences. 
 +  
 +I had to repost since we were linking to the sunscreen overview in the KB but it had become inaccessible due to the archiving. 
 +  
 +If you don't object, I'll start posting it in the public area this evening and work out with Paul what articles in the KB will link to which posts. 
 +  
 +Let me know if you have any comments or suggestions.

 Here are my experiences and success in trying to cool down while exposed to hot weather and sun. I still hot flash and do not properly perspire so I overheat very easily and become very sick if I do not cool my body down quickly once the overheating process starts.  Yesterday in Sacramento it was about 108 so even indoors I used my cooling vest  and the wet wrist bands to keep my wrists cool especially while on my lap top. Here are my experiences and success in trying to cool down while exposed to hot weather and sun.

 First off I have found that if I must be in the hot sun I must protect most of my body from the sun rays that pierces clothing and causes heat directly from contact. I prefer to wear a large lined black hooded loose fitting trench coat with hood that completely blocks the sun rays from getting near my skin.  Thin black clothing just attracts the sun and makes the skin feel hot so the coat or cover must be thick enough to block all rays while fitting loose allowing skin to breath. While the coat seems hot  it actually keeps you much cooler as it blocks out all sun. And an umbrella is a must for face and head. First off I have found that if I must be in the hot sun I must protect most of my body from the sun rays that pierces clothing and causes heat directly from contact.

 I personally like the styles that do not require ice as it melts  fast and it’s hard to replace the ice when you’re out, and ice is often uncomfortably cold. However these styles only require quickly soaking in water. I can use a public rest room or pack a small carry thermal case with cold/icy water and rewet there if necessary.  I bought two sets of wristlets and wear the 2nd on my ankles, or place one wet under bra or under panty line. Sorry to be so graphic but hey whatever cools us down. I personally like the styles that do not require ice as it melts  fast and it’s hard to replace the ice when you’re out, and ice is often uncomfortably cold.

 I have about 4 of these misters and everyone steals them from me. I don’t sweat so it really helps to apply a thin layer of mist to my face or chest and use a small personal fan to cool down for those moments when you are really overheating and just need some relief.  It is small and works on a pump action. I found mine at Wal-Mart. I have about 4 of these misters and everyone steals them from me.
