A healthy heart rate for adults typically ranges from 60 to 100 beats per minute when at rest. Factors like age, fitness level, and overall health can influence this rate. For those who are more physically active or athletes, a lower resting heart rate may be normal. It's essential to monitor your heart rate regularly, especially if you have a family history of heart conditions. If you notice a consistently high or low heart rate, it might be worth consulting your GP for further evaluation.
