Is Fast Breathing While Sleeping in Newborns Normal?
Verified By Dr. Pradeep Kumar Singh | 26-Feb-2025
Breathing patterns in newborns can often leave parents feeling puzzled or worried, especially when they observe fast or irregular breathing during sleep. It’s important to know that newborns have immature respiratory systems, and their breathing can sometimes appear rapid, uneven, or even include brief pauses. These patterns are often normal and a part of their development, but certain signs could warrant medical attention. Dr. Pradeep Kumar Singh, Consultant Paediatrician at Kailash Hospital, Greater Noida, emphasizes, “Parents should familiarize themselves with their baby’s usual breathing pattern while remaining vigilant for any concerning changes. Normal variations are common, but some patterns might indicate an underlying condition requiring medical attention.
In many cases, fast breathing in newborns while sleeping could be due to transitional physiology or temporary adaptations to their new environment. However, if the rapid breathing is accompanied by symptoms like bluish skin, flared nostrils, or noticeable chest retractions, it may indicate a more serious issue such as an infection or a respiratory condition. Dr. Singh adds, “It’s always better to consult a pediatrician if parents are uncertain. Early diagnosis can make a significant difference in addressing potential problems effectively.”

Newborns have unique and often irregular breathing patterns due to the immaturity of their respiratory systems. Unlike adults, their lungs and airways are still developing, making their breathing more noticeable and sometimes erratic. Typically, a newborn breathes 30–60 times per minute when awake and 20–40 times per minute while asleep. These rates are higher than those of older children or adults and reflect the baby's rapid metabolism and oxygen needs.
Dr. Pradeep Kumar Singh, Consultant Paediatrician at Kailash Hospital, Greater Noida, elaborates, "It's common for newborns to exhibit irregular breathing patterns, such as periodic breathing. This includes brief pauses in breathing followed by rapid breaths. These pauses, often lasting a few seconds, are entirely normal and usually don't indicate a medical concern. They occur because the brain centers that regulate breathing are still maturing. Parents should only worry if the baby shows additional signs, like a bluish tinge to the skin or persistent difficulty breathing."

Fast breathing while sleeping in newborns, medically termed tachypnea, can be attributed to several factors:
1. Immature Respiratory System
Newborns have small, developing lungs and weaker respiratory muscles compared to older children or adults. Because of this, their bodies need to compensate for the lack of efficient oxygen exchange by breathing more rapidly.
Dr. Pradeep Kumar Singh explains, “A newborn’s breathing system is still adapting to life outside the womb. Their fast breathing ensures their organs receive sufficient oxygen despite their small lung capacity.” Over time, as their lungs and muscles strengthen, their breathing patterns typically normalize.
2. REM Sleep
Newborns spend up to 50% of their sleep in rapid eye movement (REM) sleep, a stage characterized by vivid brain activity and irregular bodily functions, including breathing. During REM, an infant’s brain stimulates their nervous system for development, which may lead to rapid or erratic breathing.
This is entirely normal. Dr. Singh states, “Parents often observe irregular or rapid breathing during their baby’s sleep, especially in REM cycles. This is part of their natural sleep behavior and is usually not a cause for concern.”
3. Transient Tachypnea of the Newborn (TTN)
In some cases, newborns may experience Transient Tachypnea of the Newborn (TTN), a temporary condition caused by fluid remaining in the lungs after birth. TTN is common in babies delivered via cesarean section since they don’t undergo the natural “squeezing” process during vaginal delivery, which helps clear lung fluid. Babies with TTN may breathe quickly to compensate for the fluid’s impact on oxygen exchange. TTN typically resolves within a few days without intervention.
According to Dr. Singh, “If parents notice persistent fast breathing, especially in the first few days of life, consulting a pediatrician is essential to rule out conditions like TTN or other complications.”
4. Temperature Regulation
Newborns cannot regulate their body temperature as efficiently as adults. In cooler environments, they may increase their metabolic rate to generate heat, which can manifest as faster breathing. Conversely, if they are too warm, their body might also respond with increased respiration to dissipate heat.
Dr. Singh advises, “Maintaining a comfortable room temperature for your baby—around 20–22°C—is crucial to avoid overburdening their underdeveloped respiratory and thermoregulatory systems.”
Although fast breathing is often normal, it can sometimes indicate an underlying health issue. Parents should consult a pediatrician in Greater Noida if they notice the following signs alongside fast breathing:
- Persistent or unusually rapid breathing (>60 breaths per minute for an extended time).
- Grunting or wheezing sounds.
- Chest retractions (visible pulling in of the chest while breathing).
- A bluish tint around the lips or extremities.
- Poor feeding or lethargy.
Dr. Pradeep Kumar Singh advises, “If your newborn exhibits any of these symptoms, seek immediate medical attention. Early diagnosis and intervention can prevent complications.”
1. Respiratory Infections
Conditions like bronchiolitis or pneumonia can cause infant rapid breathing while sleeping.
2. Congenital Heart Issues
Some heart conditions may manifest as newborn fast breathing when sleeping due to inefficient oxygen circulation.
3. Sleep Apnea
Premature infants may experience pauses in breathing, known as sleep apnea, which requires medical evaluation.
4. Gastroesophageal Reflux Disease (GERD)
GERD can irritate the respiratory system, causing heavy breathing in infants while sleeping.

If your child’s fast breathing persists, a thorough evaluation is crucial. The pediatrician may recommend:
- Physical Examination: To check for visible signs of respiratory distress.
- Pulse Oximetry: To measure oxygen levels in the blood.
- Chest X-ray: To identify lung issues like infections or fluid accumulation.
- Echocardiogram: To rule out congenital heart defects.
Management depends on the underlying cause. For benign cases like periodic breathing, no treatment is necessary. For more serious conditions, interventions may include oxygen therapy, medications, or in rare cases, surgery.
Dr. Pradeep Kumar Singh emphasizes, “Timely identification of the cause ensures appropriate treatment and better outcomes. Parents should maintain regular check-ups with a child specialist.”
