Human body organs

The water of the oceans is salty because the rivers dissolve salt minerals from the mountains and bring them into the sea.
When the water evaporates at the surface the salt remains.
Over millions of years, the amount of salt reached such a scale that the sea water has become undrinkable.

What is salinity?

The salt content in seawater, expressed in grams, is called salinity. The average ocean salinity is 35ppt, which means that in every kilogram (1000 grams) of seawater, 35 grams are salt.
The ocean water in estuaries is a mix of fresh and ocean water, so the salinity there is less than the open ocean. Also, bottom water almost always contains more salt than surface waters.

Why cant humans drink salt water?

The ocean animals have same salinity inside their bodies as the water outside, because the water likes a balance. If for example salt water animal is placed in fresh water, the fresh water will enter into the animal through its skin. Also, if fresh water animal found is placed into salty water, the water inside of it will rush out.  This process in which water flows from an area of high concentration (lots of water, little salt) to an area of low concentration (little water, lots of salt) is called osmosis.
This is the main reason why humans can’t drink salt water. 
When extra salts enter the body, it will try to expel them as quickly as possible. The kidneys will try to flush the salts out in the urine, and in the process, it will pump out large amount of water - more than taken.
This leads to dehydration, and the cells and organs will not be able to function properly.

The Dead Sea is the saltiest sea in the world, six times saltier from the water in the oceans!

The Dead Sea water has so many minerals, that the head and shoulders of the swimmers are always out.  

The Dead Sea is actually a large, narrow salt lake, which lies between the River Jordan and the State of Israel. It, has the lowest elevation in the world, about 400 meters below the surface of the Mediterranean Sea.

Jet lag is the disorientation in the normal biological circadian rhythm, which is experienced by a person traveling from one time zone to another with more than four hours difference.
The greater the time difference, the greater the degree of disorientation.

Jet lag symptoms

During the time the traveler needs for his or her body to adjust to new eating and sleeping patterns, he or she may feel disoriented, tired, and “out of sync” with the new schedule, that is, sleepy during the day, awake at night, and hungry at inconvenient hours.
The body temperature may also no longer be synchronized with day and night requirements.

How to avoid jet lag

The symptoms of jet lag are often made worse by overeating and by a high consumption of alcohol during the flight, which is known to cause dehydration.
It is, therefore, advisable to drink plenty of nonalcoholic fluids during a long flight.
Some people believe that jet lag may be completely avoided by abstaining totally from alcohol and eating as lightly as possible during the flight, preferably on the schedule of mealtimes in the destination time zone.
Additionally, a diet developed by some researches is thought by some travelers to help adjust the circadian rhythms prior to flying by altering the intake of food and caffeine for several days before travel. There is no medical evidence to support this; people are advised to check with their physician before following the diet, since it could have detrimental effects on certain health conditions, such as diabetes.

Jet Lag Treatment

The body may take a long time to adjust to a new circadian rhythm, possibly as long as 10 days.
If the stay in the new time zone is to be brief, it is often advisable not to try to adapt, but rather to retain the familiar rhythm, even at the expense of unusual hours.
On a business trip this generally means that at least some working hours fall within commercial times.
A longer stay in the new time zone requires adaptation.
A mild sedative, prescribed by a physician, may help to ensure proper sleep for a few nights after arrival. The body will adjust its eating habits to conform with the new sleeping pattern.

Schools over in my nabe and summer stretches ahead, filled with promise. Vacation, pool parties, camp, catching fireflies at night, the plans are endless. For beginning readers, though, its important not to put reading on the back burner. Skills hard won over the school year can erode as the months go by.

Summer reading should never be a chore. Take kids to the library and let them stock up on books they enjoy. Used book stores are another place to get good deals on inexpensive paperbacks, as are yard sales that sprout as quickly as dandelions.

Here are some books for beginning readers that capture the essence of summer. Let the good times begin!
