Water is closely related to heart diseases
Specialists from the National Institutes of Health have already established that adequate water intake has various health benefits.
This is particularly evident in the case of the heart. Previous studies have found that proper hydration can prevent heart failure. Dr. Natalia Dmitrieva from the National Heart, Lung, and Blood Institute, who was a research team member, emphasized that alongside proper hydration, reducing salt intake can also lower the risk of cardiovascular problems.
Dr. Dmitrieva and her team decided to examine the relationship between dehydration and heart fibrosis. The research sample was indeed large. Data was collected from 15,000 adult individuals aged 45 to 66. Participants provided information about their health status and medical history over 25 years. The focus was on individuals who consumed water in amounts consistent with recommendations.
At the beginning of the study, participants did not show the presence of diabetes, obesity, or heart failure. Out of the initial group of 15,000 people, 11,814 adults developed heart failure.
The hydration level was measured based on sodium concentration in the body, which increases as the amount of fluids decreases. Scientists suggest that this connection may be responsible for the increased risk of heart disease in insufficient water intake. Therefore, limiting sodium intake can be crucial.
The proper sodium concentration in the body ranges from 135 to 146 mmol/L. A higher risk of heart failure was identified among study participants whose sodium concentration was at least 143 mmol/L. As sodium levels increased, so did the likelihood of developing this dangerous disease. Therefore, individuals concerned about their heart should regularly monitor their sodium levels.
The study's authors note that further research is needed because the issue is extremely complex and requires in-depth analysis. However, proper hydration appears to be very important for our bodies.
The recommendations regarding water intake are clear. An adult should drink about half to three-quarters of a gallon of water daily. This situation changes during heat or intense exercise—proper hydration might require drinking even one to one and a quarter gallons of water.
