Drinking plenty of water is mandatory for maintaining a good health. Staying well hydrated is crucial to human health. Scientific studies also prove that more intake of water lowers the risks of chronic health problems.

Various studies have proved that more water consumption is seemed to be linked with low mortality rate caused due to cardiovascular diseases. A lack of water causes blood to become thick, increasing risk of high blood pressure. Further, studies say that various sources of water intake help resist cancers, such as colorectal cancer, breast cancer and bladder cancer.

A recent research published in eBioMedicine is based upon the benefits of more intake of fluids/water. The study involved measuring fluid intake volume and its relative impacts on health. The researchers selected 11,255 adults and measured their internal body nutritional components based on water intake. After clinical testing, scientists discovered the amount of sodium in their blood. They used it as an indicator to measure their fluid intake. They proved that more water consumption leads to decreased level of sodium in our blood.

One of the research scientists, Natalia Dmitrieva, from the National Heart Lung and Blood Institute (NHLBI) in Maryland said, "The results suggest that proper hydration may slow down aging and prolong a disease-free life."

Previous studies have already cleared that higher sodium levels in the blood lead to the increased risks of heart failure. A person should have a normal range of 125 to 146 milliequivalents per liter (mEq/L) sodium level in the blood. Another study testing blood serum samples showed that samples with more sodium levels were also more likely to contain increased levels of about 15 different markers of biological health and aging.

Staying hydrated slows ageing and decreases risk of cardiovascular mortality. Adults who drink around two litres of water per day develop less life threatening illnesses such as heart and lung disease.

The senior investigator Manfred Boehm, from the NHLBI, while explaining about the study, quoted, "The goal is to ensure patients are taking in enough fluids, while assessing factors, like medications, that may lead to fluid loss. Doctors may also need to defer to a patient's current treatment plan, such as limiting fluid intake for heart failure."

Individuals having sodium levels higher than 142 mEq/L had a 10 to 15% odds of being biologically older than their chronological age, as compared to others having comparatively low ranges. There was also a 64% increased risk of more chronic diseases such as stroke, heart failure, chronic lung disease, dementia, diabetes and atrial fibrillation.

In another study researchers found that 20,297 adults who drank 5 or more glasses of water in a day had a 54% decreased risk of chronic diseases including coronary heart disease, stroke and diabetes as compared to participants who drank two or less glasses of water in a day.

Benefits of water consumption range from keeping the kidneys healthy to losing weight.

A researcher, Dmitrieva said, "On the global level, this can have a big impact. 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."

A research conducted at the Australian population proved that adults aged 49 years or older drinking more water found to be at decreased cardiovascular mortality and had improved kidney function.
