What Is a Safe Room Temperature for Babies

Red Nose does not recommend a specific room temperature for healthy babies.

Key Points on Room Temperature

• Babies command their temperature predominantly through the face and head. Sleeping babe on the back with the head and face uncovered is the best fashion to protect baby from overheating.

• It is not necessary to monitor the room temperature or to leave the heating or cooling on all dark, as long as the babe is dressed appropriately for the room temperature.

• Clothes baby every bit y'all would apparel yourself – comfortably warm, not hot or cold.

• A expert way to check baby'southward temperature is to feel the baby'southward back or stomach, which should feel warm (don't worry if baby's hands and anxiety experience cool, this is normal). If baby is showing signs of rut stress, remove some bedding or clothing. This may be necessary if babe is unwell, in which case you should seek medical attention.

• Ensure that baby's head and face up cannot get covered - exercise not utilize bedding such as duvets, pillows, bumpers, lambs' wool, or have soft toys in the cot or where the baby is sleeping.

• A good way to avert face roofing is to use a safety baby sleeping purse (one with fitted neck, armholes or sleeves and no hood).

• If using bedclothes rather than a sleeping bag, it is the best to use layers of lightweight blankets that can be added or removed hands co-ordinate to the room temperature and which can be tucked underneath the mattress. The bed should always be made up so that the baby is at the foot of the cot to avoid any chance of the face or head becoming covered by bedding.

• Remove babe'south bonnet, beanie, hood or hat as soon equally you get indoors or enter a warm car, bus or train, even if information technology ways waking the baby.

• Never use electrical blankets, wheat bags or hot water bottles for babies.

• Never leave infant in a machine to sleep without supervision.
  

Thermal stress (overheating) has been implicated in SUDI for many years and avoiding overheating has been one of the strategies to reduce the risk of SUDI.

With the appearance and marketing of nursery thermometers and suggested bedding configurations, parents may think they must maintain a specific room temperature in lodge to reduce the hazard of SUDI. In Australia, it is usually not necessary to measure room temperature.

There is some evidence to show that very high ecology temperatures may increase the risk of SIDS, with a recent study reporting that maximum daily outdoor temperatures greater than 29°C recorded in Canada between 1981 and 2010 were associated with a iii times greater odds of SIDS compared to 20°C. In that location was a higher odds ratio in older babies aged 3-12 months compared to younger babies aged 1-ii months.^one This finding is in contrast to earlier studies which did non find any increased rates of SIDS during a heat moving ridge in the U.s.^two or in relation to elevated maximum temperatures in Taiwan.³

With regards to the use of a fan in the baby's bedroom, a case controlled study of 185 SIDS babies and 312 controls found that the use of a fan was associated with a 72% reduction in SIDS take chances.^iv The reduction in risk was more pronounced in adverse sleeping environments. For example, when room temperatures were greater than 21°C, in that location was a 94% decreased risk of SIDS compared to no fan utilize. Fan use was also associated with reduced SIDS risk at lower room temperatures less than 21°C. The mechanism for this protective effect is unknown, but the authors suggested that fan use may reduce rebreathing of exhaled carbon dioxide trapped nearly a baby's airway past bedding.

To date, at that place is no evidence to testify that maintaining a specific room temperature prevents SUDI and that thermal factors are implicated in SIDS every bit long as:

• The baby is placed to slumber on the dorsum

• The baby is dressed appropriately for the room temperature (non over or under dressed)

• The infant's head and face remain uncovered
  

Head and Face Covering

Studies show that the risk of SUDI increases when a baby's face becomes covered by bedding, e.one thousand. sheets, blankets, quilts and duvets.^5-8 In 1996, Fleming and colleagues found that babies who died were more heavily wrapped than control infants who did non die, with the risk increasing as the tog value (a measure of thermal resistance or insulation) increased. A minor but significant proportion of these babies too wore a hat to sleep. Compared to controls, significantly more babies who died were plant at the lesser of the bed, more than were found with covers over their heads, and of these, more were sleeping under duvets.^seven

In a review of the 10 papers published on head roofing and SIDS which covered the menses between 1958 and 2003, all studies showed an increased run a risk for SIDS with a prevalence of head covering amidst SIDS victims ranging from 13% to 48% with a mean of 25%.^ix In control infants who did not die, the prevalence was 0% to vi%, mean 3.two%. The overall increased risk for SIDS was 17-fold – this is five times higher than that for prone sleeping and maternal smoking. Parents in four studies reported that over a quarter of SIDS and command infants had previously been found with their heads covered.¹⁰

Babies regulate their temperature primarily through their head, particularly their face. In a heavily wrapped baby, 85% of total heat loss is through the face.¹¹ If this normal method of heat loss is restricted past bedding covering the face, wearing a bonnet, chapeau, hood or beanie or tummy sleeping (partial face up roofing by mattress and/or bedding), there is a significantly increased hazard for thermal stress to occur.

Tuffnel and colleagues demonstrated that heat loss in tum sleeping babies is 60% less effective than for non tummy sleeping babies with the same insulation values for clothing and bedding.¹² This may explain why researchers found that tummy sleeping in combination with increased trunk insulation increased the risk of SIDS,^13-15 particularly in rooms where the heating was left on.^seven,15 Hauck and colleagues plant that breadbasket sleeping in combination with a soft bedding surface increased the risk of SIDS more than 20 times.¹⁶

The mechanism responsible for death when the face and head becomes covered is not entirely clear. Covering of the face up and head could exist associated with elevated trunk and brain temperatures. Physiological studies of head roofing have shown that, despite merely small-scale increases in body temperature, in that location are pregnant impairments in the autonomic command of both the respiratory and cardiovascular systems when babies' faces are covered by only a sail.¹⁷ There are also more frequent falls in oxygen levels and rebreathing of carbon dioxide when babies' heads are covered.^eighteen It is likewise known that babies have depressed arousal from sleep when the face is covered, even for babies sleeping in the back position.^nineteen Arousal from slumber is an important protective response to life-threatening stimuli and failure to arouse from sleep is thought to exist a possible machinery leading to SIDS.²⁰

Although evidence demonstrates an increased risk of SIDS where there is a combination of stomach sleeping, increased thermal insulation and room heating, there appears to exist no association between SIDS and high external environmental temperatures² equally long as the baby is non over insulated and is able to cool down past evaporation of sweat. Sweating is ane of the nigh important defenses against overheating and the combination of sweating with cherry-red skin may be indicative of overheating.²¹

Bed-sharing and head roofing

Sharing a sleep surface or bed-sharing with a baby can increase the hazard of SUDI and fatal sleeping accidents. Studies take suggested that more than half of all SUDI cases occur whilst the baby is sharing a slumber surface.^22-29 Some physiological studies have shown that caput covering was more common when infants slept in the parental bed compared to when they slept alone in their own cot³⁰ and more frequent falls in oxygen levels and rebreathing of carbon dioxide occurred.³¹

Bedding for babies who take a cold

Research has shown that babies with symptoms of a common cold are often given more bedding than they demand due to care giver concerns that babies showing signs of a common cold demand to be kept very warm.³² In fact, providing assistance to babies with a common cold to effectively regulate their temperature is very important. This can be best accomplished by placing them on the dorsum to sleep with the caput uncovered and removing some bedding or article of clothing. If baby is overly warm to touch, or showing signs of heat stress (irritability, looking unwell, floppy, drier skin, refusing to drink or having fewer wet nappies than usual) and so see your doctor or health professional immediately.

Conclusions

In that location is stiff evidence to testify that tum sleeping significantly increases the adventure of SUDI, particularly when the head or face becomes covered. Likewise, there is good evidence to show that the risk also increases for babies who sleep on their backs if their head or face becomes covered. Nonetheless, there is no prove to prove that actress thermal insulation increases the adventure of SIDS in babies who sleep on their back with the head and face up uncovered.^fourteen In that location is also no evidence to support maintaining a specific room temperature or any specific bedding configurations (number of blankets required) as this depends on a number of factors such as what the baby is wearing, whether it is summer or wintertime and whether there is heating or cooling inside the room where the baby is sleeping.

The Red Nose Safe Sleeping program is based on scientific evidence and was developed by Australian SUDI researchers, paediatricians, pathologists, and child health experts with input from overseas experts in the field. The 85% driblet in SIDS deaths and the 9,967 lives that have been saved is testament to the effectiveness of the program.
