A lower resting heart rate is better when it comes to your health. It's a sign your heart is working well. When it's lower, your heart pumps more blood with each contraction and easily keeps a regular beat. On the flip side, a high resting heart rate may mean your heart works extra hard to pump blood.

When you are exercising, your muscles need extra oxygen—some three times as much as resting muscles. This need means that your heart starts pumping faster, which makes for a quicker pulse.

You're Too Stressed Prolonged mental and emotional stress can also cause your resting heart rate to creep up over time. If “fight-or-flight” mode becomes your norm, the associated increase in your resting heart rate can produce a higher risk of heart attacks, strokes, and much more.

Your heart rate or rhythm can change when you are under stress or having pain. Your heart may beat faster when you have an illness or a fever. Hard physical exercise usually increases your heart rate, which can sometimes cause changes in your heart rhythm.

Frequent exercise will cause your heart to grow stronger, making it easier for it to distribute blood throughout your body. A stronger heart means that each time your heart beats, it pumps more and more blood throughout you body. This allows your heart to beat less, while still distributing the same amount of blood.

When your heart beats it pushes blood around your body. This heart beat can be felt as your 'pulse' on your wrist or neck. Your pulse is measured by counting the number of times your heart beats in one minute. For example, if your heart contracts 72 times in one minute, your pulse would be 72 beats per minute (BPM).
