From the Oura data we can see that the most common lowest nocturnal heart rate is 55. The lowest night-time HR values range from 35 to 84, with 50% of the people with values between 51 and 60. From the Oura data we can see that the most common lowest nocturnal heart rate is 55.

A common cause of a rising heart rate during sleep is a lack of oxygen, which is often brought on by obstructive sleep apnea. This is a condition where a person's normal breathing frequency is reduced or sometimes flat-out stopped during sleep.

Generally, a lower resting heart rate indicates a higher level of cardiovascular fitness. “The more you exercise and the harder you train, the lower your resting heart rate,” Welch says. That's why resting heart rate is often cited as a good measure of how fit a person is.

Laskowski, M.D. A normal resting heart rate for adults ranges from 60 to 100 beats per minute. Generally, a lower heart rate at rest implies more efficient heart function and better cardiovascular fitness. For example, a well-trained athlete might have a normal resting heart rate closer to 40 beats per minute.

During sleep a slow heartbeat with rates around 40–50 bpm is common and is considered normal. When the heart is not beating in a regular pattern, this is referred to as an arrhythmia.

As a general rule, adults will have a resting heart rate of 60 to 100 beats per minute (bpm). In general, people with better physical fitness will have slower heart rates than pepole who exercise less. Athletes, for instance, may have a resting heart rate of just 40 to 60 bpm.

Slow heart rates didn't occur during the day, according to the study. Other types of abnormal heartbeats (arrhythmias) were also significantly higher at night when blood sugar was low compared to when blood sugar was normal.

Take your heart rate 1–3 minutes following an intense effort. The healthy and fit heart sees a faster decline in beats per minute. A decrease between 15–25 heart beats per minute is the normal range.

In general, for adults, a resting heart rate of fewer than 60 beats per minute (BPM) qualifies as bradycardia. But there are exceptions. Your heart rate may fall below 60 BPM during deep sleep.

Brain waves become even slower. REM sleep first occurs about 90 minutes after falling asleep. Your eyes move rapidly from side to side behind closed eyelids. Mixed frequency brain wave activity becomes closer to that seen in wakefulness.

Having bradycardia (say "bray-dee-KAR-dee-uh") means that your heart beats very slowly. For most people, a heart rate of 60 to 100 beats a minute while at rest is considered normal. If your heart beats less than 60 times a minute, it is slower than normal. A slow heart rate can be normal and healthy.

For children ages 6 to 15, the normal resting heart rate is between 70 and 100 bpm, according to the AHA. But a heart rate lower than 60 doesn't necessarily mean you have a medical problem. Active people often have lower heart rates because their heart muscles don't need to work as hard to maintain a steady beat.

The average resting heart rate is usually between 60 and 80 bpm. But some athletes have resting heart rates as low as 30 to 40 bpm. If you're an athlete or someone who exercises often, a lower resting heart rate isn't usually anything to be worried about, unless you're dizzy, tired, or ill.

For resting heart rate, normal is defined as 60 to 100 beats per minute, but trained athletes can have resting heart rates as low as 35 to 40, which is normal for them.

It's a sign of good health. But if it's too slow, it could be a symptom of a condition called bradycardia. Normally, your heart beats 60 to 100 times a minute when you're at rest. But with bradycardia, it goes down to less than 60 beats a minute.

Overnight heart rate It's primarily because the nerve signals that slow down your heart rate increase when you're sleeping, while at the same time, the nerve signals that increase heart rate are suppressed. Because sleep is such a dynamic and cyclical process, your heart rate may fluctuate throughout the night.

During the first sleep cycles, your body relaxes and your blood pressure and heart rate drop. Your lowest heart rate happens at the midpoint of sleep when the amount of melatonin is at its highest. If you are perfectly aligned with the rhythm of the sun, your lowest basal body temperature also occurs around 4 am.
