Why is baby’s room temperature important? 

If you’re not sure why the temperature in a nursery is important, it’s key to note that it’s not only a matter of comfort, it’s also a critical safety consideration. This is because babies are not able to regulate their body temperatures as effectively as an older child or an adult. A baby's body surface-to-weight ratio is about three times that of an adult. This means that they can lose heat very quickly. This is especially true if your little one was born prematurely or at low birth weight. However, even full-term newborns are unable to maintain their body temperature if the environment around them is too cold. In fact, they lose body heat about four times faster than adults. What’s more, unlike adults, newborns are unable to shiver to increase their body temperature when it drops below the normal range. If a baby’s body temperature does drop below a normal range, it can impact their breathing and their body’s use of oxygen. So, it’s important to ensure that baby’s room temperature stays within an ideal range. 

You may wonder if it’s just low temperatures you need to be concerned about. Unfortunately, your baby can also overheat if they are in an environment that is too warm or if they’re overly bundled up. Ensuring a comfortable and safe body temperature for your little one can be a tricky balancing act. That’s why maintaining the correct room temperature for newborn is so critical. 

What temperature should a baby’s room be?

The ideal temperature for your baby might vary slightly from the ideal temperature for another baby. These differences relate mostly to what type of climate your newborn is accustomed to. However, although there may be slight differences in the ideal temperature for a baby room, it is recommended that nursery rooms are kept between 68 to 72 degrees Fahrenheit or 20 to 22 degrees Celsius. This temperature range is ideal because it not only helps your little one maintain a healthy body temperature but also allows them to sleep peacefully while still waking up to auditory signals. This helps decrease the chance of Sudden Infant Death Syndrome (SIDS).

Tips for maintaining baby’s room temperature

In order to ensure the temperature in your baby’s room stays within a safe range, it’s a good idea to have a thermometer handy. Many baby monitors also have room thermometers built in which can be very helpful. Finally, wearable baby monitors that measure your little one’s vitals are now readily available as well. However, there is no substitute for the watchful eye of a parent so no matter what tools you have at your disposal, make sure that you are regularly checking in on your little one. 

How can I tell if my baby’s room temperature is too hot?

A normal body temperature for a baby is 97.7° F or 36.5°C. While you can always take your baby’s temperature to determine if they are too warm, there are also a few easy-to-spot warning signs that you can look out for to indicate the nursery is above the ideal temperature for a baby room.

Here are some key indicators that your baby is overheating: 

• They feel warm to the touch 
• Their skin is red or flushed 
• They are nauseous or vomiting 
• They have an elevated heart rate 
• They are acting tired or sluggish
• They appear to be confused, disoriented, or dizzy 
• They are sweating or they have damp hair 

If you are worried that your baby is overheating there are a few things you can do to reduce their body temperature:

• Offer your baby fluids (breastmilk, formula or a glass of water if they are old enough) 
• Give your baby a spongebath with lukewarm water

How can I tell if my baby’s room temperature is too cold? 

Just like overheating, babies show signs of distress that are easy to spot when the temperature in their nursery is too low. A baby who is too cold will give you some warning signs that their body temperature is not quite right. 

Here are some key indicators that your baby’s body temperature is dropping below a normal range: 

• They become sluggish or unresponsive
• Their cry is weaker than usual 
• Their skin is pale and cold to the touch 
• They are having trouble breathing
• They are not feeding 

If you suspect that your baby is too cold here are a few things you can do right away to try and warm them up:

• Add additional warm layers of clothing
• Use your own body heat by holding your baby close to you. You can also drape a blanket over them just be sure to never leave them unsupervised with the blanket.
• You may also want to try swaddling your baby

If you’ve tried to warm your baby up using these techniques but their body temperature is not rising, call your paediatrician immediately.
