What is considered to be a normal heart rate?

Sleeping heart rate should generally be somewhat lower than normal resting heart rate, while upward, because the body is usually released very deep during sleep. When one begins to fall asleep, heart rate begins to slow down and studies suggest that this process can begin as soon as one knows that he is preparing for sleep. As the body relaxes into a deep state of sleep, the temperature of the body can usually decrease in addition to heart rate and metabolism usually slows down. The level of physical fitness, age and recent level of stress can affect the sleeping heart rate. However, most experts believe that normal heart rate should be eight to ten percent lower than normal resting heart rate while it is awake. Sleeping heart rate, which is not at least eight percent lower than normal resting heart rate, while upwards could be a sign of danger.

There are at least five phases of sleep and sleeping heart rate may vary in each of the sleepphase. The first four phases of sleep, generally the category, the body is becoming more and more relaxed. This process of physiological relaxation is about 80 percent of the sleep time of most people. The heart rate usually begins to slow down as soon as the sleep is one phase, and slows down how the body further relaxes.

heart rate can often differ often during REM sleep, in the fifth phase of sleep, during which dreaming usually occurs. The rapid movement of the eyes (REM), sleep, is thus named because the movements of the eyes of a sleeping person are usually visible to all observers. Physiological conditions may vary very much during REM sleep, perhaps depending on the emotional reactions of sleep to its dreams. The heart rate can increase significantly during REM sleep and can even exceed normal resting heart rate while it is awake. The respiratory speeds may also increase and other physiologists may occurFunctions such as sweating.

Some of the prolongs suggest that heart rate during sleep can be a good hint of possible mortality in the next seven years of life of the sleepers. The Israeli study suggests that people who do not experience at least eight to ten percent reductions in heart rate may be up to two and a half times more often more often in the next seven years of their lives. The study also seems to suggest that people with chronic health such as diabetes, hypertension and obesity are likely to experience the least reduction in heart rate while sleeping.
