Ideal nursery temperature for newborns: how to keep your baby’s room safe
Keeping your baby’s nursery at a safe, comfortable temperature is one of the simplest ways to support better sleep and reduce risks like overheating. Whether you’re wondering when to use a 2.5 tog sleeping bag, or if it’s safe to use a fan in those warmer summer months, here’s everything you need to know.
What’s the best nursery temperature?
The ideal nursery temperature is between 16°C and 20°C (around 61°F to 68°F). This range is recommended by health experts from both the NHS and The Lullaby Trust, to reduce the risk of Sudden Infant Death Syndrome (SIDS), and to make sure your baby sleeps safely and comfortably.
Why nursery temperature matters
Babies can’t regulate their temperature like adults can, so they’re more sensitive to heat and cold. A room that’s too warm can increase the risk of overheating, while a room that’s too cold can disturb their sleep - and no parent needs to be woken up more than they already are!
How to check nursery temperature
Use a nursery room thermometer to monitor your baby’s room. Options like a nursery wall thermometer or a digital display on a baby monitor can help you stay on top of changes, especially in summer or winter.
Our top tip: The best nursery room thermometer is one that’s easy to read at a glance, and gives you an alert when the temperature gets too hot or cold.
What should my baby wear at night?
The right clothing depends on both the nursery temperature and what your baby is sleeping in.
Here's a quick guide
Always check your baby’s chest or back - not their hands or feet - to see if they’re too hot or cold. Organic cotton clothing, like our sleepsuits, can help keep heat in when it’s cooler, and allow baby’s skin to breathe when it’s warm.
Should I use a fan in the nursery?
Yes, absolutely - using a fan in the nursery when it’s too warm can help circulate air and keep your baby cool, safe and comfortable. Just make sure it’s not blowing directly on your baby and the room doesn’t get too cold.
Best nursery thermometers to try
Look out for handy features like:
- Room alerts for high or low temps
- Nightlight and digital display
- Wall-mounted or portable
Keeping baby safe and comfy
Getting the nursery temperature right doesn’t have to be complicated. With a good nursery room thermometer, the right clothing layers, and a little awareness of tog ratings, you can create a calm, safe sleep space for your baby, whatever the weather!
TL;DR: Here’s your nursery temperature checklist
- Keep nursery between 16–20°C
- Use a reliable thermometer for nursery
- Adjust baby’s clothing to suit room temp
- Use a 2.5 tog grobag for standard conditions
- Add or reduce layers depending on season
- Use a fan to help airflow (but not directly on baby)
