Some heart rate ranges can be dangerous and may lead to health risks. Our heart rate changes based on activity, stress, and overall health. While occasional changes are normal, constant high or low heart rates can signal problems. In this blog, we will explain what a normal heart rate is, when it becomes risky, and what steps to take if it goes beyond the safe range.
Understanding Heart Rate Basics
Heart rate is the number of times your heart beats per minute (BPM). It is an important sign of heart health and fitness. Factors like age, fitness level, and emotions can affect it.
Normal Heart Rate
For most adults, a resting heart rate is between 60 and 100 beats per minute (bpm). Several factors can affect this:
- Age: Kids and teens usually have higher heart rates than adults.
- Fitness Level: Athletes often have lower heart rates, sometimes as low as 40 bpm.
- Emotions: Stress, anxiety, and excitement can temporarily raise the heart rate.
Heart rate naturally changes with stress, exercise, and sleep. After activity, it should slowly return to normal.
When Heart Rate Becomes Dangerous
Having a heart rate that is too high or too low for a long time can be a sign of health problems. Here’s what you need to know:
Tachycardia (High Heart Rate)
– Definition: A resting heart rate over 100 beats per minute.
Possible Causes:
- Dehydration: Low blood volume makes the heart work harder.
- Fever: A high temperature can raise the heart rate.
- Anxiety or Stress: Emotional stress can cause a fast heartbeat.
- Medical Conditions: Issues like hyperthyroidism or heart disease may lead to long-term tachycardia.
Risks:
If the heart beats too fast for too long, it can lead to serious problems like heart failure, stroke, or even sudden cardiac arrest, especially in people with existing heart conditions.
Bradycardia (Low Heart Rate)
Definition: Bradycardia means a resting heart rate below 60 beats per minute.
Causes:
– Heart problems: Conditions like heart disease or blocked signals in the heart.
– Low thyroid function: An underactive thyroid can slow the heart rate.
– Electrolyte imbalance: Too much or too little potassium or calcium can affect heart rate.
Risks: Severe bradycardia may cause dizziness, tiredness, or fainting. In extreme cases, it can lead to heart failure or sudden cardiac arrest.
When to See a Doctor
A slight change in heart rate is usually normal. But if you notice these symptoms along with an unusual heart rate, it’s best to get medical help:
- Feeling dizzy or lightheaded often
- Trouble breathing
- Chest pain or discomfort
- Feeling extremely tired
- Fainting
Monitoring Your Heart Rate
Keeping track of your heart rate can help prevent potential heart problems. Many fitness trackers and smart watches have built-in heart rate monitors, making it easy to check. Both high and low heart rates can stress your heart and increase the risk of serious conditions like heart attacks and strokes. It’s also helpful to know how to check your pulse manually on your wrist or neck.
Conclusion
Your heart rate is an important indicator of your health. While some changes are normal, consistently high or low heart rates may signal a problem. Understanding what’s normal can help you take better care of your heart. If you’re ever concerned, it’s best to consult a doctor.
