but it already has been popular for many years.
It probably started at the Dead Sea,
one of the world's saltiest bodies of water,
where swimming is similar to floating
because of the high concentration of salt in its water
and can't possible sink any human or animal alike.
spas in some parts of the world uses a tank bigger than a bath tub
and fills it with salt solution that's approximately 800 pounds of salt
dissolved in 200 gallons of water.
The guest then can float in the tank for hours depending on the spas
where he will experience unlike anything before.
Floating in this extremely salty water releases stress and tension,
and promoting over all sense of calmness and peace.
It also relieves pain in the head, neck, arms and shoulders,
and including back and leg pains
because every inch of the contours of your body
are well supported by the salt solution that not even the softest
and most comfortable bed and pillow can ever do.
