If you often feel tired and dizzy on August 1st (Thursday)... Is this a sign of deficiency in 'this'?

If you suddenly feel dizzy and tired recently, you might suspect "dehydration." During summer, a large amount of water is lost through sweating. A lack of bodily fluids can cause various symptoms in our body. Changes in mental functions such as mood swings, as well as physical symptoms like lethargy and fatigue, can appear.

Our body is composed of about 70% water. If we are short of only about 2% of this water, our body feels thirst. When the deficiency reaches 3-4%, symptoms such as dizziness, fatigue, and decreased concentration appear. Blood volume in the body also decreases, which can lead to a drop in blood pressure. Over 90% of blood is made up of water.

If you are taking medication for high blood pressure or have a heart disease, you need to be more cautious. When hypertensive patients are dehydrated, their blood vessels constrict and urine output is suppressed, negatively affecting blood pressure. If the fluid level in the blood of heart disease patients decreases, the blood becomes more viscous and sticky, increasing the risk of blockages in the heart and blood vessels.

Not skipping meals also helps with hydration. Regardless of the type of food, about 80% of a meal's content is water, so if you don't eat rice, your water intake will inevitably decrease. If you feel dry mouth, fatigue, and notice dark urine, suspect chronic dehydration and seek appropriate treatment. Children may experience dehydration symptoms such as a red face, distracted attention, and a decrease in urination.
