What is pulse rate in human body?
A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

What is the pulse rate?
The heart rate is measured by the pulse rate. The number of times the heart beats each minute is known as the heart rate. The arteries expand and constrict with the flow of blood as the heart pumps blood through them. Taking your pulse not only monitors your heart rate, but it can also reveal the following information:

Rhythm of the heart
The intensity of the pulse

A healthy adult's pulse rate ranges from 60 to 100 beats per minute. Exercise, illness, injury, and emotions can cause the pulse rate to rise and fall. Females with a heart rate of 12 and up have a quicker heart rate than males. Athletes that perform a lot of cardiovascular fitness, such as runners, may have heart rates near 40 beats per minute.

How to check your pulse
When the heart pumps blood via the arteries, you can feel the beats by pushing strongly on the arteries, which are close to the skin's surface at various sites on the body. The pulse might be felt on the side of the neck, within the elbow, wrist, or groyne. Taking the pulse at the wrist is the most convenient method for most people. If you're going to use the lower neck, don't press too hard. Never press on both sides of the lower neck's pulses at the same time. Blood flow to the brain may be obstructed as a result of this.

When taking your pulse, press firmly but softly on the arteries with your first and second fingertips until they feel warm.

When the clock's second hand reaches the number 12, begin counting the pulse.
For 60 seconds, count your pulse (or for 30 seconds and then multiply by 2 to calculate beats per minute).

When counting, don't look at the clock all the time; instead, focus on the pulse's beats.

If you're not sure about your results, have someone else count them for you.

If you're having problems finding your pulse after your healthcare practitioner has requested you to do so, talk to your provider or nurse for help. There are a variety of monitoring equipment that may be used to check your pulse. Fitness tracker devices, for example, can help you keep track of your pulse rate.
