Obesity is a term that means you weigh at least 20% more than what is considered a normal weight for your height. It makes you more likely to have conditions including: Heart disease and stroke.
An Isotonic Solution creates a mild, less concentrated salt solution of 9mg of Sodium Chloride per mL of water, which has a similar salt concentration as your body and may be more comfortable to use for some people initially compated to the more concentrated Hypertonic solution.
In case of a saline solution (seawater included), it means that an Isotonic solution is 9â° (that's NOT 9% - that's PARTS PER THOUSAND) salt and 991â° purified water. In a roundabout way, one might say that Isotonic seawater has only 1/3 the salt content of regular ocean water (not the Dead Sea!).
