Open MRI - any dangers?

Apart from fishs and chillest water in open sea, what other dangers are to be faced ?

  • yatch riders simply fall into sea and get in to vesseles .if only there are no dangers in the sea of water ,for those who can swim better, i hope there can be no dishasuter for life

  • Answer:

    Its usually not the fish you have to worry about unless they are pelagics (sharks) or venomous (Portugese man of war jelly,box jelly,moon jelly) it is the hypothermia that you have to worry about as your body loses heat faster by conduction in the water than in air, Water conducts heat away from your body about 4 times faster than air. One other worry would be dehydration even though you have big blue all around you. The Na content in the water will dehydrate you quickly, even through your skin by osmosis.

If they fall overboard close to a shore line then they can swim to shore although trying to swim a mile or more is very tiring. You can suffer from a lack of water (I know you're surrounded by it) as you don't drink sea water (salty) and the lack of food unless you catch a fish (rather hard to do) and eat it raw. So you suffer from exposure (very tiring), fatigue, lack of food and water. Many die even only being a few miles offshore due to the effects of the cool water and the draining effects of swimming a long distance. Really depends on where you go overboard. Far off shore or close in.
