Heart rate is the record of your heart beats taken in a minute, and it does change as you age. A baby usually has a faster heart rate compared to teenagers and young adults. A newborn baby has a heart rate that falls between 70 and 190, with an average heart rate of 125 beats per minute. At around the first year of life, the baby's heart rate goes down between the range of 80 to 160 beats per minute, with an average of 120.
As the child grows up, the average heart rate is around 100 beats per minute. It goes down to 90 beats per minute as the child reaches 10 to 12 years. By age 18, the range of heart beats fall between 55 to 90 beats per minute, averaging around 70 beats per minute. An adult usually has a heart rate between 60 to 100 beats per minute.
How to Measure Your Heart Rate
You can measure your heart rate by checking your pulse. Just place your right hand's index finger and middle finger on the thumb side of your left wrist. Feel for the pulse, and when you're sure you have it, you can measure your heart rate by counting the beats of your pulse for 60 seconds. You can also shorten it by counting your pulse for just 15 seconds, and then multiplying it by the number four to obtain your heart rate per one minute.
When Should You Measure Your Heart Rate?
Your heart rate changes when you're exposed to certain temperatures, such as the heat of the sun, and when you have just finished exercising. It is usually faster after these conditions. It is best to measure your heart rate when you are at rest. Your resting heart rate is best taken in the morning after you wake up. It can also be measured when you are most relaxed during the day.
What Can Cause Your Heart Rate to Change?
There are many factors that can affect your heart rate. Exposure to heat, stress and some drugs can make your heart rate go faster. Infections and fever can also increase your heart rate. Your emotions also have some great effect on your heart rate. Moments of anger, anxiety and fear can also trigger a sudden increase in your heart rate. Frequent intake of caffeinated drinks also may cause a faster heart rate.
What is an Abnormal Heart Rate?
A frequent heart rate of more than 100 beats per minute, or tachycardia, can signify some underlying heart conditions. A consistent heart rate of less than 60 per beats per minute, or bradycardia, especially if it is accompanied by fainting and shortness of breath, can be a cause for concern. You may need to see your physician in these cases to have a proper evaluation of your health.
