The moisture in the body consists of the moisture consumed and the moisture produced by metabolism, which is contained in the beverage and food, which is produced by the oxidation of hydrogen ions in the food, and the daily water intake may vary depending on age and gender, depending on the season.
The daily intake of water depends on salt intake, weight, temperature, activity or body calorie consumption, and 30ml of water per kilogram is generally recommended.
Nutrition standards were established and age-based standards were established, and 2,100 ml of water was calculated from these data for senior citizens aged 65 or older, of which 1,100 ml was presented for consumption from solid foods (rice, grain, vegetables, etc.).
Water in the body plays a role in maintaining body temperature, transporting nutrients and waste matter, and basic maintenance of tissue structure, which is essential for cellular metabolism, including brain cells, and proper water intake is very important for maintaining new functions, immune systems, and blood relationships.
As aging progresses, the total body fluid (TBF) of the human body significantly decreases in relation to the increase in body fat.
In other words, most tissues in the body, such as muscles, skin, heart, and liver, contain 60% for men and 52% for women, but less than 10% for fat tissues, 52% for men and 46% for women over 60.
This reduces the water content of the body in relation to the increase in body fat as the elderly are more fat than adults and women are more fat than men.
In the case of the elderly, dehydration was reported to be more likely to occur than young adults, and in the case of the elderly, once the phenomenon occurs, recovery is difficult.
The 24-hour moisture limit reported a significant increase in plasma osmosis, sodium, and vasopressin over adults (20-31) in the healthy elderly (65-75 years old), and an adult recommended an hour of water intake after the 24-hour water restriction, but did not return to normal.
In other words, in the case of the elderly, the constancy is degraded, suggesting that if the water balance is broken, it is difficult to recover from the water imbalance unless it is quickly assessed and adjusted.
A prior study, which reported the relevance of age and water intake, found that as age increases, physiological changes caused by aging gradually reduce the sense of thirst, preventing proper intake of water even if the body lacks moisture.
In fact, according to a study conducted on the amount of water consumed by elderly people aged 65 or older, the total amount of water consumed by elderly people was significantly lower than that of young people.
Low cognitive function or lack of communication skills make it difficult for senior citizens to express thirst or demand water, and poor mobility due to chronic diseases or aging can be an obstacle to finding and drinking water on their own.
Environmental constraints that make it difficult for elderly people who have been hospitalized for a long time at nursing facilities to get the drink they want and difficult to drink at the time they want were found to be a cause of water intake disorder.
A study on the relationship between water intake and health status of elderly people in facilities showed that the better the physical health of elderly people in nursing homes, the lower the water intake.
Researchers inferred this result as a result of the lower frequency of direct nursing intervention provision, the better the physical health condition, and similar claims were made for elderly people who were hospitalized.
However, in cases where hospitalization is prolonged due to the chronic disease problem, etc. accompanying them; Nursing providers will overlook the assessment of the water intake of the elderly and dehydration due to the lack of water intake.
A prolonged lack of moisture can lead to acute confusion, health problems such as dehydration, urinary tract infection, respiratory infection, and constipation, and physiological imbalances in older people can reduce their ability to respond to environmental and physiological stress, resulting in serious health problems.
Body changes have led to a decrease in urinary and respiratory infections, weight retention, urinary incontinence, decreased uric acidity, decreased colorectal cancer, decreased constipation, decreased incidence of acute congestion, decreased incidence of standing low blood pressure, falls, dehydration.
It was suggested that sufficient nursing personnel are deployed to provide moisture from time to time and that strict supervision of proper provision of moisture is a way to improve water intake. This indicates that insufficient water intake is a health problem that can be improved by the care provider's attention and mediation.
Therefore, it is believed that water intake education is necessary for nursing providers to recognize the need for moisture in the elderly and monitor the amount of water in the elderly to prevent health problems caused by lack of water through proper water intake.
