Water is a
chemical compound that is dispersed in large quantities in the ground; It
covers 70% of its area, and it is also an essential element for the life of
animals, plants, and people on earth.

living things, and the human body in particular consists of no less than 70% of
water, and is responsible for the completion of chemical reactions in the body.
Many people do not take the importance of drinking enough water daily
seriously, as they consume less than what the body requires to maintain the
activity of its organs and its natural functions, but what many people are
unaware of is that the most common and most prevalent diseases are mainly due
to the dehydration of the human body from water, and in this article, we will
talk about what causes the lack of drinking water.
What are the symptoms of dehydration?
Dizziness and headache

to a lack of the number of fluids surrounding the brain, and dehydration causes
a slight flow of oxygen from the blood to the brain.

soften the digestive system, maintains its cleanliness and resilience, which
helps in regular bowel movements and prevents constipation, and also the lack
of water causes vomiting, diarrhea, or stool leading to constipation.

decision-making, and mood, and causes difficulty in focusing, forgetting, and
continuous thinking, in addition to lack of sleep, fatigue, and failure to
perform cognitive tasks.
Urine color changes
Urination
between four to seven times a day is a healthy process, and in case of little
urination, this is evidence of the body’s lack of water, and the color of urine
indicates the level of hydration; As the color of light or transparent urine
indicates that the body is moist, and yellow or dark urine indicates the body’s
lack of water.
