0.9% is the same salinity as that of your blood. This is important to consider when using an intravenous (I.V.) system.
If a higher percent salinity were used (more salt content), the blood composition would be too salty (hypertonic). This would draw water out of body tissues causing dehydration and high blood pressure.
If a lower percent salinity were used (less salt), then the blood composition would be too dilute (hypotonic). This would draw excessive amounts of water into the bodily tissues and cause bloating as well as red blood cell lysis. The same thing happens if you drink too much purified water.
Human blood just happens to be at a 0.9% salinity concentration. This is mainly due to the number of electrolytes, salts, and other molecules that inhabit the blood.
Hope this helped!

I presume it matches the saline content of the body's natural fluids. So you can put it in your eye (for example) without drawing water into or out of your eye.

Same osmotic pressure as blood.

You can float in it.
