I was going to start a thread about this, funnily enough.
Last year I went on holiday in the blazing heat and sun, and while I certainly didn’t experience a recovery my reliance on meds to help get a full and refreshing sleep ended immediately. It might have just been a coincidence that I stopped taking meds at that point, but I’d tried that before without success. It also seemed to clear up my residual bad fatigue. I generally felt as good as I can these days, although I guess the sun does that to your mood anyway if you don’t get it so often.
I noticed sps recently said he was on holiday and experienced a good improvement as well as bluecloud above. I think ‘chi’ also said he felt nearly recovered on holiday in the sun just after crashing. There have been loads of guys saying being in the sun helps.
It’s difficult to establish what is going on, as although the link with vit d seems obvious if that means it is increasing testosterone then lots of us don’t normally react well or get any benefit from that. Clearly if it was a crucial factor then the board would also be skewed towards guys from northern Europe, Canada etc like MS - yet there are loads of Italians on here for example.
One thing I seem to notice is that a lot of the bad crashes seem to have occurred in the darker months of October to March. I know when the shit hit the fan with me I was going to work in the dark and coming home in the dark, mostly staring at a computer for the hours in between.
