When you sleep, your body isn't doing as much, so your heart can slow down. “Sleep is your time to reset. If you're not getting that recovery phase, your adrenaline levels during the day can be higher,” Dr. Mills-Frazier says. Excess adrenaline charging through your system during the day can lead to a faster heartbeat.

Immediately after exercising, the heart's rate was likely in the upper end of its target heart-rate zone. As soon as resting started, its rate should have quickly decreased. Specifically, one minute after rest started the heart rate likely rapidly dropped.

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.

They found that not only did evening exercise not affect sleep, it seemed to help people fall asleep faster and spend more time in deep sleep.

Sleep apnea and bradycardia: The cardiovascular connection A slow heart rate can mean you're not getting enough oxygen, and failure to get enough oxygen is symptomatic of sleep apnea, a condition that causes you to continually wake up throughout the night because of obstructed breathing.

Should I be worried? A: It is not uncommon for atrial fibrillation (AFib) to occur at night. The nerves that control the heart rate typically are in sleep mode, and resting heart rate drops. Under these conditions, pacemaker activity from areas other than the normal pacemaker in the heart can trigger the onset of AFib.

Your heart rate may fall below 60 BPM during deep sleep. And physically active adults (and athletes) often have a resting heart rate slower than 60 BPM.

The Hammock: Relaxed in Bed. 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.

By doing these 4 things you can start to lower your resting heart rate and also help maintain a healthy heart: Exercise more. When you take a brisk walk, swim, or bicycle, your heart beats faster during the activity and for a short time afterward. But exercising every day gradually slows the resting heart rate.

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. Or it could be a sign of a problem with the heart's electrical system.

Sleep apnea and heart rate fluctuation 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.

Stress: Anxiety, depression, and stress can affect your heart rate. Alcohol or caffeine: Having either of these stimulants close to bedtime can cause your heart to race and make it difficult for you to sleep. Bedtime snacks: What you eat also affects your heart.
