Perhaps your seizures are moisture-related, rather than temperature-related? Several of my seizures (complex partials) occured when at least part of me was immersed in water...several while I was in the shower and one while I was in the middle of my OCD-handwashing. A lot of them also occurred when I was sweating heavily, though these drenching sweats may have even been simple partials in disguise that spread into complex partials. I just wonder if anybody out there has an answer as to how I'm to determine if these 'sweat attacks' are simple partials in disguise?
I wonder, too, if your seizures might be related to solar/geomagnetic activity? And doesn't salt water 'conduct'? Two of the websites in the following thread can be searched backwards and compared to your seizure diary.

Salt must have something to do with seizures though because I swear I read that low sodium can trigger them?...and sweats often occur for days prior to my own seizures, so my body must be trying to get rid of the sodium for some reason?
