Bradycardia is a slow heart rate -- fewer than 60 bpm. Your resting heart rate typically drops below 60 bpm when you're sleeping. Some athletes and young adults can have heart rates of 40-60 bpm as well. More seriously, bradycardia results from your heart being unable to pump well enough...
Heart rate is the number of times the heart beats each minute. Daily activities can change how fast or slow the heart beats – from a slow, steady beat while resting or sleeping to a higher rate during exercise. "There's a wide variation in what a normal heart rate can be depending ...

What is a good HRV while sleeping? In general, heart rate is low and heart rate variability is high during nighttime. During sleep, the parasympathetic nervous system activity dominates, lowering heart rate, body temperature, and relaxing muscles. Our heart rate while sleeping can be 20-30% ...
There’s no doubt about it: Americans have a sleeping problem. According to the CDC, more than a third of Americans are not getting enough sleep on a regular basis, while roughly 70 million Americans suffer from chronic sleep problem. And things have only gotten worse over the past year. ...

It is also possible to define your breathing frequency by asking other people to count the number of your breathing cycles for one minute when you are sleeping. (During sleep the respiratory frequency remains about the same as during wakeful states at rest, but the tidal volume or amplitude ...
1Citations Abstract Normal human sleep is generally divided into four stages. Consensus definitions for the visual scoring of sleep were published in 2007 and the reader is referred to the American Academy of Sleep Medicine Scoring Manual for full definitions and criteria for the scoring of sleep ...
Health visitors and general practitioners are often asked for help because of what parents perceive as a baby's sleeping problem. Many parents expect that the baby will be sleeping continuously through the night from a given age, often as early as six weeks old. The conflict between the parent...
