Things that affect heart rate

Knowing your heart rate (pulse) can help keep tabs on your physical fitness, even if you’re not an athlete. The American Heart Association says factors that may influence heart rate include:
Health Tips
* High temperatures and humidity, which can increase heart rate.
* The position of your body during the first 20 seconds after standing up.
* Strong emotions.
* Obesity.
* Medications. For example, beta blockers commonly taken by cardiac patients may decrease heart rate, while thyroid medications may increase it.
