70% of the human body is water. Once the body is dry, all parts of the body may strike. The United States "Fox News Network" recently reminded that in the hot summer, we must be alert to the 10 major signs of water shortage.
Dry mouth tongue swelling
The first sign of lack of water in the body is thirst. Dehydration can cause dry mouth and slight swelling of the tongue, so drink water in summer.
Urinal deep yellow
As the blood pressure drops and the body tissue becomes dehydrated, the dehydrated kidneys concentrate the urine and even prevent urine production. As the urine concentration increases, its color gradually deepens, and it is dark yellow or even amber when severe.
constipation
Constipation occurs when the bowel absorbs excess water. Once the body is deprived of water, the intestinal tract will absorb more water to supplement the body fluids, resulting in dry stools.
Lack of skin elasticity
Dehydration reduces skin elasticity. The doctor quickly checks the elasticity of the skin through a “pinch test†to determine if the patient is dehydrated.
Experts remind: look at the eyes meet the water to meet the standard
Summer temperatures are high, sweat secretion is strong, and water loss is large. Therefore, it must be replenished in time. Generally speaking, “Drink 8 cups a day†is just a recommendation because each person has different amounts of water loss and the amount of supplements will naturally vary. The basic criterion for measuring whether or not the body is deprived of water is: I am not thirsty, and my eyes are rich and shiny.
Heart
Like other muscles in the body, the decrease in blood flow caused by dehydration and electrolyte changes can lead to heart palpitations.
Muscle cramps
Chronic water shortages can cause electrolyte imbalance in the body, leading to persistent muscle spasms during or after exercise.
dizzy
In addition to decreased blood flow and blood pressure, dehydration can also cause dizziness. One of the key signals is sudden dizziness when standing up quickly.
exhausted
Long-term lack of water can easily lead to a decrease in blood flow and blood pressure, and the blood oxygen content also decreases. Without sufficient oxygen, muscles and nerves function will be weakened, and therefore more fatigue.
No tears
Even though there was no tears when crying out loud, the body certainly lacked water.
Feeling overheated
Water plays a key role in regulating body temperature. Once you feel overheated, the body lowers body temperature by sweating. Once the body is dehydrated, it will stop sweating and cause the body to overheat.
