Did not know about sun impact, I always lather it on being fair with blue eyes but will be super vigilant now. Are there any articles that point out the dangers of sun and PV? I know about extreme Temps either way should be avoided. I vacation often in Maine during the summer and it's cool enough for me to hang on the beach all day, I don't like heat much. Should I consider not being out there during peak sun hours? Maybe I'll post a question. Thanks very much for this info and hope your hubby finds his new norm quickly. I haven't found mine yet, diagnosed in April but I'm getting there. I was having weekly draws, then 2 weeks and we're trying a month now. No meds, just low dose aspirin.
