“We all know that water consumption is necessary for our bodily capabilities,” Thomas Boyden, MD, director of preventive cardiology at Corewell Well being, stated. “Good hydration generally retains sodium ranges down, and that may cut back strain on the center.”

The research discovered larger serum sodium ranges had been related to a better danger of growing coronary heart issues later in life. A better consumption of fluids may assist decrease the serum sodium ranges.
Whereas Dr. Boyden agrees that consuming water is sweet for well being, he cautioned that the research’s findings aren’t conclusive.

What we do know: An excessive amount of sodium could make it tougher to your coronary heart to pump blood. The center can weaken or stiffen when sodium ranges are too excessive, Dr. Boyden stated.
And that may enhance blood strain.
