Water is Your BFF
Dehydration is known to have a deleterious effect on heart function, according to a review published in 2019 in Nutrients. When you are dehydrated, your heart needs to work harder to pump blood, which may cause your heart to beat faster. That may lead to an irregular heartbeat or heart palpitations. Dehydration also makes your blood thicker and constricts the walls of blood vessels, which strains the heart and can possibly lead to high blood pressure.
While staying hydrated may help with blood pressure and staving off weight gain, an article published in September 2022 in Hospital Nutrition also noted that adequate hydration is linked to lower incidences of fatal coronary heart disease and lower risk of both high blood sugar and type 2 diabetes. Dehydration, on the other hand, is linked to weight gain and obesity.
