Once you have located your pulse, you can proceed to count the number of beats per minute (bpm) to determine your heart rate. Here's how to do it:

1. Find a Comfortable Position:
Sit or stand in a comfortable position with your back straight and your feet flat on the floor. Avoid talking or moving excessively during the measurement.

2. Place Your Fingers Correctly:
Place your index and middle fingers on your pulse point (wrist, neck, or temple). Press gently but firmly enough to feel the pulse clearly.

3. Start Counting:
Look at a clock or timer and start counting the number of beats you feel in one minute. You can count the beats out loud or silently to yourself.

4. Count Accurately:
Make sure you count each beat distinctly. If you lose track, start counting again from the beginning. It's helpful to tap your foot or finger along with each beat to maintain a steady count.

Counting your heart rate manually is a simple and effective way to measure your heart rate without any special equipment. It's particularly useful when you don't have access to a heart rate monitor or smartwatch.

Rest before measuring

To ensure an accurate heart rate measurement, it's important to rest for a few minutes before taking your pulse or using a heart rate monitor. Here are a few reasons why resting is essential:

• Eliminate Physical Exertion:
  

  Physical activity increases your heart rate. Resting allows your heart rate to return to its normal, resting state, providing a more accurate measurement.

• Reduce Anxiety and Stress:
  

  Stress and anxiety can temporarily elevate your heart rate. Taking a few minutes to relax and calm down before measuring your heart rate helps minimize these effects.

• Ensure Consistent Measurements:
  

  If you measure your heart rate immediately after exercise or during stressful situations, the results may vary significantly from your resting heart rate. Resting before measuring ensures consistency in your heart rate readings.
