Children's Heart Rate: Awake vs. Sleeping

What is the difference in heart rate between children when awake and when sleeping?

a) Higher when sleeping, lower when awake
b) Higher when awake, lower when sleeping
c) The same when awake and sleeping
d) Unpredictable, not influenced by sleep
Final answer:

Final Answer:

Children have a higher heart rate when awake due to increased oxygen demands and a lower heart rate when sleeping.

Heart rate (HR) by age in children when awake and sleeping is typically higher when awake and lower when sleeping. When children are awake, their bodies have an increased demand for oxygen-rich blood due to physical activity and other factors which results in a higher heart rate. On the other hand, when children are sleeping and at rest, their heart rate tends to be lower since the demand for oxygen decreases.

The difference in heart rate between awake and sleeping children is influenced by various factors including age, activity levels, hormones, and temperature. For instance, a newborn may have a higher resting heart rate compared to a young adult, and this rate can change as they grow older. Additionally, factors such as hormones, ion levels, body temperature, oxygen levels, and pH balance can also play a role in influencing heart rate.
