Why Does Your Heart Rate Increase At High Altitude

When you travel to high altitudes your heart rate will naturally increase in order to get more oxygen to your body. This response is called the “acute mountain sickness (AMS) bradycardia.” Your heart rate will increase because your body is trying to compensate for the lack of oxygen in the air. The higher you go the more your heart rate will increase.

There are a few theories as to why this happens. One theory is that the increased heart rate is the body’s way of trying to improve the blood’s oxygen-carrying capacity. Another theory suggests that the body releases more of the hormone epinephrine (also known as adrenaline) at high altitudes which can cause an increase in heart rate.

Whatever the reason it is important to be aware of the potential for increased heart rate at high altitudes. If you are planning to travel to a high altitude be sure to check with your doctor to see if you are at risk for AMS. And if you do start to feel the symptoms of AMS be sure to descend to a lower altitude as soon as possible.
