Lack of water in the body can cause serious health problems. With age, as well as under the condition of physical inactivity and malnutrition, the situation can only get worse.
Mild dehydration causes fatigue during the day, blurred consciousness, chapped lips, and dry eyes. Against the background of a lack of moisture, bad breath, constipation, infections of the excretory system and headaches can also appear.
If dehydration continues for a long time, health problems can become serious. In particular, a person has problems with joints, heart disease, Alzheimer's disease, diabetes mellitus, and immunity decreases.
According to a recent study by scientists, if a person lacks even 2% of the norm of water per day, then cognitive functions can be greatly reduced: memory deterioration is observed, concentration of attention decreases, reports "Reedus".
Also, due to a lack of moisture, the work of the cardiovascular system is disrupted. Due to the thickening of the blood, the heart works with increased stress.
