Drink enough water
Heart palpitations may result from dehydration. Because your blood contains water, it might get thicker when you become dehydrated. Your heart has to work more to pump blood through your veins the thicker it is. That might make your heart beat faster and possibly cause palpitations.
The research was conducted by Natalia Dmitrieva of the US National Institutes of Health and colleagues: "Our study suggests that maintaining good hydration can prevent or at least slow down the changes within the heart that lead to heart failure", Dr. Dmitrieva. Grab a glass of water if you notice an increase in your heart rate. Drink more fluids if you notice your urine has a dark yellow color to avoid heart palpitations. Many experts recommend drinking around 2 liters of water daily (1.6–2.1 for women and 2–3 for men).
