  1. this wont be harmful unless that salt concentration is very high


  2. In both cases, you'd feel pretty bad until your body managed to excrete the excess. I used to feel like a stuffed turkey after an IV.

    In the case of salt water, however, your body would need a lot of water to remove the excess salt, so at the end of it you'd be dehydrated.

    Water retention is not caused by excess water, but by excess salt. The body has top use water to keep these salts diluted to a nontoxic level, meaning extra weight and blood pressure problems.

  3. If you need to ask the question then it will probably be harmful as you won't know how to safely inject.

  4. First, think about why, when someone wearing cologne walks into a room sooner or later, their smell spreads out over the whole room ... it is because of diffusion.  Diffusion is the movement of molecules from an area of high concentration to an area of low concentration.  

    So, with the cologne, you have a higher concentration of cologne molecules and the room has a lower concentration.  So, the molecules of cologne, that are nearest to you, collide with each other and then bounce off of each other ... they diffuse.

    The same is true for cells and salt water.  The cell membrane is not permeable to salt, but it is permeable to water.  Inside of the cell there is a higher concentration of water than the concentration of water in the salt water.  So, the molecules of water diffuse from inside of the cell to the outside and the cell looses.

    Just plain water will do nothing.

  5. it actually could be harmful.

    and plain water is worse.

    hospitals use saline solution, when you're dehydrated.

    plane water messes up your salt balance, which is fairly critical.  

  6. It totally depends on how injected.
