It's for injuries, strain, sore muscles, etc.

You shouldn't be icing or heating more than 20 minutes at a time. That number varies from doctor to doctor though (but you shouldn't be heating an injury for the first day or so - it'll only make it more sore - ice reduces the extent of the injury during the initial few days).... Heat pulls blood to the surface - if you've got a sore muscle, that blood can put pressure on pain receptor/nerves if you're applying heat for too long...

true, but you normally dont spend 10+ hours of holding your body against one ...

(radiation decreases with the square of the distance ... eg double distance, 1/4th of radiation)

i am worried, but dont have sufficent in-depth electric / medical knowledge to confirm/reject this ...

cheers 2 all, al
How many power lines are in/near your home (including buried ones)? Perhaps you're not spending 10+ hours holding your body against them - but you're immersed in them 24 hours a day When you quarter a small amount, it's still a small amount

It's a funny thing to watch... I live in Florida - and whenever the local news brings out the next "dangerous" household product, the parental stupid gene kicks in.... Yet, not one person I know puts sun block on every single day. I mean, it's well known - that radiation will kill you - even through clouds
