Why sea water cause dehydration?

Sea water does not cause dehydration. It can, however, lead to dehydration if a person drinks too much of it.

Drinking seawater can lead to dehydration because the salt content in seawater is much higher than the salt content in the human body. When a person drinks seawater, the body must work harder to excrete the excess salt. This process requires the body to use water, leading to dehydration.

In addition, the high salt content in seawater can damage the cells in the body, further contributing to dehydration.

Symptoms of dehydration can include:

* Thirst

* Dry mouth

* Fatigue

* Headache

* Dizziness

* Confusion

* Seizures

* Coma

If you are experiencing any of these symptoms, it is important to seek medical attention immediately.
