Detailed explanation-1: -You can check your heart rate by taking your pulse and counting how many times your heart beats in 1 minute (60 seconds). Your heart rate varies depending on what you’re doing – for example, it will be slower if you’re sleeping and faster if you’re exercising.
Detailed explanation-2: -When you feel your pulse, count the number of beats in 15 seconds. Multiply this number by four to calculate your beats per minute.
Detailed explanation-3: -A normal resting heart rate should be between 60 to 100 beats per minute, but it can vary from minute to minute.
Detailed explanation-4: -The normal range is between 50 and 100 beats per minute. If your resting heart rate is above 100, it’s called tachycardia; below 60, and it’s called bradycardia. Increasingly, experts pin an ideal resting heart rate at between 50 to 70 beats per minute.
