Link Between Hydration and Aging Process

new study by the National Institutes of Health (NIH) identifies the key role hydration is thought to play in the aging process. This new research serves as great proof of the importance of drinking enough water to stay properly hydrated.

The study determined that middle-aged persons with higher sodium-to-water levels in their blood biologically age faster.

Decreased hydration levels were actually shown to accelerate the process of biological aging despite chronological age, our age measured in years from our birth.

According to an NIH press release, “The results suggest that proper hydration may slow down aging and prolong a disease-free life,” said Natalia Dmitrieva, Ph.D.

“Decreased body water content is the most common factor that increases serum sodium, which is why the results suggest that staying well hydrated may slow down the aging process and prevent or delay chronic disease,” said Dmitrieva.

Serum sodium is the amount of sodium relative to the volume of water in the blood, and it goes up as hydration is reduced. Serum sodium can be detected by a simple blood test, and according to the Mayo Clinic, a normal blood sodium level is between 135 and 145 millimoles (mmol) per liter.

Researchers found that people with higher serum sodium were biologically older than their cohorts of the same chronological age and also more prone to chronic, debilitating diseases that can reduce quality of life.

People in the original blue zones make drinking water a part of their daily routines. Hydrating primarily with water is just one of the recommendations which were designed so that you can eat – and drink – just like the longest-lived people in the world for the same longevity benefits. The guidelines advise drinking at least 7 glasses of water daily.

Here are some tips to help you get your daily recommended amount of water.

  1. Infuse water with fruits or herbs to add flavor and texture
  2. Brew and drink decaffeinated, herbal teas
  3. Drink water when you first wake up
  4. Eat more hydrating foods like celery, cucumber, apples, and melons
  5. Track your daily water intake using a free smartphone app
