- Summary
Many factors, including age and activity levels, affect a person’s respiratory rate. Adults usually take between 12–20 breaths per minute, but children tend to breath faster.
The respiratory rate is the number of breaths someone takes every minute. It is one of the main vital signs, along with blood pressure, pulse, and temperature.
Some health issues — such as anxiety, a fever, or heart problems — can cause breathing rates to speed up.
This article looks at the normal respiratory rates in adults and children. It also discusses the causes of high or low respiratory rates and when a person should contact a doctor.
Although respiratory rates can vary slightly between individuals, there is a standard range for doctors and nurses to consider. The following table outlines normal respiratory rates based on age:
The authors of a 2022 article state that children have a higher respiratory rate than adults. Once a child reaches the age of 2, the respiration rate reduces from 44 breaths per minute to 26.
It is essential to measure a person’s respiratory rate at rest. Exercise or even walking across a room can affect it.
To take an accurate measurement, watch the person’s chest rise and fall. One complete breath comprises one inhalation when the chest rises, followed by one exhalation when the chest falls.
Breathing relies on the coordination of the control center in the brain and the respiratory muscles. An area at the base of the brain controls breathing. The brain sends signals from the brain to the breathing muscles.
Sometimes, the body needs to adjust the breathing rate. Receptors in the brain detect low oxygen or high carbon dioxide levels and send signals to the body, which can change the breathing rate.
Having an atypical respiratory rate can indicate a variety of things. In some cases, a high or low respiratory rate is due to an activity, such as exercise, and is not an indication that there is anything wrong.
Sometimes, though, various diseases, injuries, and substances can lead to a change in breathing. In a medical setting, an atypical respiratory rate, especially if it is too fast, can indicate a health problem.
Doctors refer to a high respiration rate of more than 20 breaths per minute as tachypnea.
Common causes of high respiration rates include:
•Anxiety: People may breathe faster when they are afraid or anxious. Fast breathing, or hyperventilation, is a common symptom of panic attacks. The fast breathing will usually pass once the anxiety goes away.
•Fever: As body temperature increases with a fever, respiratory rate can also increase. The increase is the body’s way of trying to get rid of the heat.
•Respiratory conditions: Conditions that can increase a person’s respiration rate include:
•chronic obstructive pulmonary disease
Doctors refer to a low respiratory rate of fewer than 12 breaths per minute as bradypnea. This can occur as a result of a worsening of an underlying respiratory condition. It can also occur as a result of airway obstructions and cardiac arrest.
Other causes include:
•Drug overdose: The use of alcohol and other depressants, such as narcotics and benzodiazepines, can depress the breathing drive in the brain, leading to low respiration rates.
•Obstructive sleep apnea: Sleep apnea involves a blockage of the airway, often due to the relaxation of the soft tissues in the throat. The blockage causes brief pauses in breathing and may decrease the overall respiratory rate.
•Head injury: Head injuries can affect the area in the brain that plays a role in breathing, which may cause a decrease in the respiration rate.

A mild variation from the typical respiratory rate may not be a cause for concern. But in some cases, a respiratory rate that is too high or too low can be a sign of a medical problem.
If the respiratory rate is atypical or a person has signs of infection such as fever, fatigue, or a sore throat, they should consult a doctor.
People with lung diseases, such as emphysema, asthma, and chronic bronchitis, may also want to contact a doctor if their respiratory rate is often atypical. It can be a sign that their lung disease is worsening.
Seek immediate assistance if any of the following is present:
•chest pain
•cyanosis, when the skin turns blue
The outlook of a person with a low or high respiratory rate depends on the underlying cause.
A normal respiratory rate varies based on age and activity levels. But various conditions, including illnesses and injuries, can also lead to a breathing rate that is too high or too low.
A person’s respiratory rate is the number of breaths they take per minute. This can vary from person to person. However, a typical breathing rate for an adult should fall between 12–20 breaths per minute. The normal breathing rate for children varies depending on their age.
A high or low respiratory rate may be a sign that an underlying issue is present. Potential causes of a high respiratory rate include anxiety, fever, respiratory diseases, heart diseases, and dehydration. Potential causes of a low respiratory rate include drug overdoses, obstructive sleep apnea, and head injuries.
If a person is experiencing an atypical breathing rate, they should contact a doctor. Seek immediate medical help if a person also has chest pain, bluish skin, gurgling sounds during breathing, or breathing very few breaths per minute.

In order to reap the benefits of exercise, your heart and breathing rates must increase. Your muscles are pushing your blood back to your heart at a faster rate, so your heart must increase its rate of pumping to match. Some of the blood pumped by the heart travels to the lungs to get rid of carbon dioxide and pick up oxygen. Video of the Day.
- Exercise and Breathing Rate. During exercise, your body needs to maintain a constant supply of oxygen in your cells to support your working muscles, which might need 15 to 25 times more oxygen than when they are resting, according to Williams Sport Training.
- Exercise and Heart Rate. Your cardiovascular system is in charge of delivering blood and nutrients to your working muscles and keeping your body temperature within a normal range.
- Exercise and Body Temperature. As your body converts food into energy during exercise, it produces heat as a waste product. This extra heat can elevate your body temperature above the typical 98.6 degrees.
- Maintaining Homeostasis of Fluid Levels. If you don't eat and drink properly, you will impair your homeostatic response. Your body needs water to maintain a normal temperature and blood volume, but sweating can dehydrate you.
Because your heart is a muscle, it becomes conditioned with regular activity and requires less effort to pump oxygenated blood. This is reflected both during and following exercise. Your heart rate will still increase while exercising, but not as sharply because the heart is strengthened; your breathing will intensify, but you may be less winded.

Oct 15, 2024 · The normal respiratory rate for a healthy adult during exercise can increase to 40 to 60 breaths per minute. The increased breathing rate allows more oxygen to reach your lungs. Children also breathe faster while exercising, and they may occasionally feel mildly short of breath for a temporary time.

Mar 16, 2020 · Effect of Exercise on Breathing Rate. Just as exercise raises your heart rate, it also raises your breathing rate. The direct relationship between exercise and respiratory rate is that you will begin to take in more oxygen — about three to four times as much, to be exact.
