Many forget to drink water during the winter, which exposes them to dehydration, severe lack of fluids in the body, and dehydration. Headache Many physiological problems, and the elderly are more at risk.
A new research study revealed that dehydration and lack of water in the body also affects cognitive function, and excess dehydration also affects mental performance.
According to the site medicalnewstoday A recent research has been conducted to find out whether moisture levels can affect cognitive performance in adults or not, as dehydration can cause headaches, lethargy, dizziness, and many other problems, depending on the severity of dehydration.
Studies tend to focus on the effects of dehydration in younger people especially in the context of sports and fitness, as excessive stress and abundant sweating can cause more fluid to be lost than people who eat them, however, one segment of people is particularly vulnerable For dehydration they are the elderly.
With age, our water reserves decrease due to low muscle mass, and our college becomes less effective at retaining water, and hormonal signals that lead to thirst and stimulate the amount of water become weaker, according to Hillary Bethancourt of Pennsylvania State University at the College of Health and Human Development.
“We felt it was very important to look at cognitive performance regarding hydration and water intake among older adults who may be overexposed,” says study author Bethancourt. “.
The researchers analyzed data from 2,506 participants, including 1,271 women and 1,235 men aged 60 and over 2014.
All study participants were able to give blood samples. They also provided information about what they consumed throughout the day before collecting blood samples to measure the water levels of each participant. The researchers studied the concentration of different substances and compounds including sodium, potassium, glucose and urea nitrogen in their blood..
All participants also performed cognitive functional tests, including tasks designed to assess recall and verbal fluency, and exercises focused on levels of attention and working memory.
At first glance, the researchers found a relationship between proper hydration and good results in cognitive function tests, however the results became less clear when researchers modified their analysis of confusing factors..
“Once we calculated the age, education, hours of sleep, level of physical activity, state of diabetes and separate data analysis for men and women, the associations containing moisture state and amount of water were reduced,” says Betancourt.“.
The researchers found that women began to exhibit poor cognitive performance when exposed to dehydration, and the same is true when they experience an excessively dehydrated state.
