Aging: how to delay old age, according to science?

Some people get old faster than others, others live up to the old age successfully without disease, while certain subjects develop chronic diseases related to the age. According to a new study, this would depend on how well hydrated everyone is present, as this avoids illnesses related to the aging.
What relationship does hydration have with aging?
According to a study of National Institutes of Health (NIH, in English) of the USA, and published in the scientific journal eBioMedicineit is known that In mice, the restriction of Water for life shortens the useful lifely promotes degenerative changes, and found that in the humans something similar happens.
“The results indicate that proper hydration can slow aging and prolong a life free of disease.”

The study, based on data from 11,255 adults, collected over 30 years, indicates that middle-aged people whose serum sodium exceeds 142 mmol/l have a higher risk of being biologically olderdevelop chronic diseases and dying at an earlier age.
The blood sodium levels appeared to be related to agingmeasured this in 15 categories that included systolic blood pressure, cholesterol, blood sugar, and others related to cardiovascular, respiratory, metabolic, and immune functioning.
How to delay old age, according to science?
Because the aging increases sodium levels in the blood, a researcher Natalia Dmitrieva noted that fluid intake may help delay age effects.
In this sense, most people can safely increase their fluid intake to reach recommended levels and this can be done with both Water as with other fluids, for example, vegetables and fruits with a high water content.
- The National Academy of Medicine recommends a daily intake of about 6 to 9 glasses (1.5 to 2.2 liters) of fluids for most women, and 8 to 12 glasses (2 to 3 liters) for men.
The researchers emphasized in their report that these findings do not prove a cause-and-effect relationship, and that further studies will be needed to determine whether optimal hydration can promote growth. healthy aging preventing diseases.
