Your heart rate, or pulse, is the amount of heart beats per minute. 1. How to find your pulse in your neck: Place your first finger and middle finger (not thumb) to the side of your neck, just under your jaw and beside your windpipe. Press your skin lightly until you feel a beat. If you can't find it, try pressing a bit harder or softer, or move your fingers around. Use a watch or stopwatch and count the number of beats you feel in a minute (60 seconds). Alternatively, you can count the number of beats in 15 seconds and multiply this number by 4 to calculate your beats per minute. 2. How to find your pulse in your wrist: Place your index and middle finger (not thumb) on the inside of the wrist until you feel a beat. Use a watch or stopwatch and count the number of beats you feel in a minute (60 seconds). Alternatively, you can count the number of beats in 15 seconds and multiply this number by 4 to calculate your beats per minute. Image Source: How to Take A Pulse - What You Need to Know (2021).
