Proper Hydration Would Help People Live Longer

A recent study published in eBioMedicine has found a link between hydration in the body and better health.

In this research, scientists from the United States National Institute of Health conducted a cohort analysis on nearly 16,000 participants between 45 and 66 years old. Data were collected over a period of 25 years, between 1985 and 2021.

They measured water intake through the levels of serum sodium, which may become higher when people do not consume sufficient water. The healthy range should be between 135 and 145 milliequivalents/liter.

Results from the analysis have shown that the life expectancy of mice without sufficient water intake was 6 months fewer than those with enough water consumption. In humans, this is equivalent to around 15 years of lifespan.

The recent development of some biomarkers for measuring human aging made it possible to verify these findings in humans. These include cholesterol, blood sugar, blood pressure, as well as other factors that indicate the functions of the immune, renal, metabolic, respiratory, and cardiovascular systems.

Specifically, the study suggested that those with low levels of serum sodium may be at a much higher risk of getting older more quickly. In other words, long-term hypohydration would make people more susceptible to chronic conditions and death at a younger age.

The recommended daily water intake is still not fully agreed upon. As a rule of thumb, 64 ounces or 8 full glasses are supported by a lot of scientific evidence.

However, the specific amount can vary from person to person. Younger and more physically active individuals may need more water on a daily basis than older and less active ones. On the other hand, people with certain health issues, such as kidney failure, may need less water to prevent possible complications.

When it comes to water, go for plain water. Electrolyte drinks, tea, and coffee may be taken into account as well, but they should not the main source. You may also add water-rich foods to the diet, such as fruits and vegetables.

Overall, keeping the body properly hydrated plays an important role in living a healthy and long life for everyone. This is especially true for older individuals.

To ensure your goal, it is a good idea to keep track of your daily water consumption, particularly when you participate in sports, physically activities, or live in hot environments.
