Ask Adam Ep 8 - “Why does my resting heart rate (RHR) spike when I’m dehydrated?”



Yo, what is going on, guys?! Welcome to another episode of Ask Adam. All right, today's question was,

I've noticed that when I'm dehydrated, my resting heart rate spikes. Why is this?"

Well, simple answer is the less amount of water you have in your body, or the more dehydrated you are, the less amount of blood you have going on.


So lesser blood volume, less certain amount of blood volume is definitely going to mean that your heart's got to work harder to push blood throughout the body, which means an increased heart rate.


While you're sitting there dehydrated, you're going to notice an increase in heart rate simply because your body has to work harder, and that's just on one biological process.


Your body is also going to work harder to transport and store carbs.


Your body is going to work harder to transport and utilize fats.


Your body is going to work harder to digest food.


Literally anything and everything you are doing in those moments, your body is working hard to do, which means an increased heart rate.


Guys, I hope this helps out.


Make sure you drop those questions in the link in my bio. I want to know them. I want to help out.


Have an amazing day!
