In a resting state, the normal heart rate of adults is between 60 to 100 beats per minute (BPM). If the heart rate is less than 60 beats per minute, it is called bradycardia.
Many athletes and people who exercise regularly have bradycardia all the time. Their heart rate is much slower than the average person, about 40 to 50 beats per minute.
Because their hearts are more efficient at pumping blood, each heartbeat can pump more blood to meet the body’s needs.
If your heartbeat is too slow but it doesn’t cause any symptoms, generally doesn’t require treatment.
For those who do have symptoms, such as dizziness, lightheadedness, chest pain, shortness of breath, fatigue, feeling weak and so on, should go to the hospital immediately. Bradycardia is almost always treatable.
Numerous studies have shown that “The Slower the Resting Heart Rate, the Longer the Lifespan“. If the resting heart rate is maintained at around 60 beats for a long time, a person can live longer than 90 years.
Animals are just like humans. The rat’s heart beats as high as 500 beats per minute, and its lifespan is only 2 years. The turtle’s heartbeat is only 6 beats per minute, and the turtle can live up to 200 years.
