A person's respiratory rate is a vital sign that can indicate their overall health. It is the number of breaths they take per minute and is usually monitored for at least 60 seconds. During sleep, a person's respiratory rate tends to decrease, with breathing evening out and becoming less variable as they progress through the stages of sleep. However, in REM sleep, which is an active period of rest associated with vivid dreams, the respiratory rate increases and becomes less regular. Several factors, such as age, activity levels, and health conditions, can influence a person's respiratory rate while sleeping or awake. For example, children tend to breathe faster than adults, and conditions like anxiety, fever, or heart problems can cause higher respiratory rates. On the other hand, certain health conditions, such as hypothyroidism, sleep apnea, or head injuries, can lead to lower respiratory rates.
| Characteristics | Values |
|---|---|
| Respiratory rate during sleep | Lower than during wakefulness |
| Respiratory rate during REM sleep | Greater than during non-REM sleep |
| Respiratory rate variability (RRV) | Greatest during wakefulness and REM sleep, decreasing with depth of sleep |
| Respiratory rate and age | Children breathe faster than adults |
| Causes of high respiratory rate | Anxiety, fever, respiratory diseases, heart diseases, dehydration, etc. |
| Causes of low respiratory rate | Drug overdose, sleep apnea, head injuries, hypothyroidism, sodium azide poisoning, carbon monoxide exposure, etc. |

Sleep apnea is a breathing disorder that causes a person's breathing to slow down or stop during sleep
Sleep apnea can manifest in two major forms: obstructive sleep apnea and central sleep apnea. Obstructive sleep apnea (OSA) occurs when the muscles in the throat relax during sleep, causing the surrounding tissue to press against the windpipe and block air movement. Central sleep apnea (CSA), on the other hand, is caused by the brain failing to send signals to the breathing-related muscles, resulting in interrupted breathing patterns.
People with sleep apnea may experience unusual breathing patterns, such as fast breathing that gradually becomes shallower until it stops, after which the cycle repeats. This disorder can cause a person to wake up frequently throughout the night, disrupting their sleep cycle and preventing them from getting restful and healthy sleep.
The condition can be diagnosed with the help of healthcare providers, who may use tools like video and audio recordings of the patient's sleep, the apnea/hypopnea index (AHI), or in-lab sleep studies to determine the severity of the disorder. Treatment options are available, and seeking medical assistance is crucial to managing symptoms and preventing potential complications.
While sleep apnea specifically refers to the cessation of breathing during sleep, it is worth noting that a person's respiratory rate naturally decreases during sleep, with the slowest breathing occurring during deep sleep. This is a normal part of the sleep cycle and should not be confused with sleep apnea, which involves complete breathing cessation or abnormally slow breathing.

A person's respiratory rate is the number of breaths they take per minute
During sleep, an individual's breathing pattern typically slows down, and it reaches its lowest point during deep sleep. This decrease in respiratory rate is a natural process. However, certain health conditions, such as sleep apnea, heartburn, or other disorders, can cause an abnormally low respiratory rate, a condition known as bradypnea. Sleep apnea, for example, involves brief pauses in breathing due to airway blockage or relaxation of soft tissues in the throat. Other causes of bradypnea include drug overdoses, head injuries, hypothyroidism, and exposure to toxins like sodium azide and carbon monoxide.
In contrast, a respiratory rate that is abnormally high is called tachypnea. This condition can be caused by various medical conditions, including anxiety, infection, fever, respiratory diseases, heart diseases, dehydration, and certain lung conditions.
The respiratory rate is a vital sign that provides valuable insights into an individual's overall health. It is essential to monitor and assess respiratory rate during sleep and wakefulness to identify any potential underlying health issues. Healthcare professionals use different methods, such as stethoscopes, manual counting, or technological monitors and sensors, to measure respiratory rate accurately.
It is important to note that the normal respiratory rate during sleep varies with age. Children, for instance, tend to have a higher respiratory rate than adults, and their respiratory rate at rest decreases as they grow older.

A low respiratory rate can be caused by heartburn, sleep apnea, or other health conditions
A person's respiratory rate is the number of breaths they take per minute. Like body temperature and heart rate, it is a vital sign that can offer a window into a person's overall health. Both during sleep and wakefulness, a low or high respiratory rate can be due to a health condition.
A low respiratory rate can be caused by sleep apnea, a breathing disorder that causes a person's breathing to slow and stop for brief periods while they are asleep. There are two major forms of this disorder: obstructive sleep apnea and central sleep apnea. People with sleep apnea may experience excessive daytime sleepiness, loud snoring, morning headaches, and decreased concentration.
Heartburn, or acid reflux, can also cause a low respiratory rate. This occurs when stomach acid rises into the oesophagus, causing a burning feeling in the chest. Acid reflux can be aggravated by a large, rich meal or lying down too soon after eating. It can also cause indigestion, acid regurgitation, and coughing.
Other health conditions that can cause a low respiratory rate include hypothyroidism, which may cause lethargy, dry skin, and hair loss; sodium azide poisoning, which can lead to headaches, dizziness, rashes, weakness, nausea, and vomiting; and exposure to carbon monoxide, which can cause dizziness, cardiovascular toxicity, and coma. Certain toxins, such as sodium azide and carbon monoxide, can slow the central nervous system and cardiovascular system, leading to low respiratory rates. Additionally, conditions that affect nerves or muscles involved in breathing, such as Guillain-Barré syndrome or amyotrophic lateral sclerosis (ALS), can also lead to low respiratory rates.

A high respiratory rate can be caused by anxiety, infection, or lung conditions
A person's respiratory rate is the number of breaths they take per minute. Like body temperature and heart rate, it is a vital sign that can offer a window into a person's overall health. Respiratory rate at rest changes as a person grows older. Generally, children breathe faster than adults, and their average respiratory rate at rest decreases with age. The normal respiratory rate for a healthy adult is between 12 and 20 breaths per minute. A rate of below 12 or above 20 can indicate a disruption in the breathing processes.
Infections can also cause a high respiratory rate. For example, a chest x-ray can reveal pulmonary causes of a high respiratory rate, such as pneumonia, pneumothorax, or cystic fibrosis.
Finally, lung conditions can lead to a high respiratory rate. Obstructive lung diseases, for instance, can be evaluated through pulmonary function tests.

The normal respiratory rate during sleep depends on age
Children have a higher respiratory rate than adults, and their average respiratory rate at rest decreases with age. A child's normal breathing rate varies depending on their age. For instance, a newborn typically takes 30 to 60 breaths per minute, while a 2- to 11-month-old's normal breathing rate is 20 to 40 breaths per minute.
Healthy adults usually take between 12 and 20 breaths per minute while at rest. A respiratory rate of below 12 or above 20 breaths per minute can indicate a disruption in the breathing processes. During sleep, a person's respiratory rate tends to slow down, reaching its lowest during deep sleep. In REM sleep, a person's respiratory rate increases and becomes less regular.
Abnormal respiratory rates can be a sign of an underlying health issue. A high respiratory rate can be caused by anxiety, fever, respiratory diseases, heart diseases, dehydration, or lung conditions. A low respiratory rate can be caused by drug overdose, sleep apnea, head injuries, heartburn, or other health conditions. If a person is experiencing an atypical breathing rate, they should seek medical advice.
