Day 2: Does it really take two minutes for my blood to circulate throughout my body?

My absolute favorite part of yoga is the relaxation time at the end where you just get to lie there and breathe. I’m super awesome at this pose. Today the instructor stated that we should do this for at least two minutes because that’s how long it takes for your blood to flow throughout your body. Really?

I guessed that the process would take longer.

"You have about 5 litres of blood in your body (at least most people do) and the average heart pumps about 70 ml of blood out with each beat. The next bit is going to depend on your resting heart rate. I think most people have an average resting heart rate of about 70 beats a minute (somewhere around there).  So, if you multiply the amount of blood that the heart can pump by the number of beats in a minute, you actually get about 4.9 litres of blood, which is almost your whole body’s worth of blood. So, in a minute, you will pump the entire blood volume around your body."

So, I was wrong. But, so was she perhaps. I’m guessing everyone’s hearts were still pumping at an above average rate so our blood could very well have circulated even faster, but it depends on so many variables. Can you think of some?
