Stay Hydrated
Dehydration can be the cause of heart palpitations sometimes. Heart palpitations happen because the heart works harder than it should when trying to pump blood throughout the body. Dehydration causes the heart to work more than necessary to circulate blood. This is because the lack of water makes your blood thicker and requires more force to be moved along blood vessels.
While you should drink plenty of water throughout the day, it is especially important when you are dehydrated. Signs of dehydration to look out for include darkening of your urine, dryness in your mouth, accelerated heart rate, dermal dryness, headache, and dizziness. [3] In general, you should drink water whenever you are thirsty or your urine is not clear. These are the first signs that you need water.
