Helping Your Child Sleep During Hot Weather: A Parent's Guide
When the weather heats up, sleep can suddenly feel much harder for everyone in the family.
Babies, toddlers and older children often struggle to settle, wake more frequently, or seem restless throughout the night when they're too warm. As parents, it can be difficult to know how best to help while also making sure your child stays safe. The good news is that there are some simple things you can do to help your little one stay cool and comfortable during warmer nights.
Why Does Heat Affect Sleep?
Our bodies naturally lower their core temperature as we prepare for sleep. When the environment is too warm, this process becomes more difficult, making it harder to fall asleep and stay asleep.
Babies are particularly vulnerable because they cannot regulate their body temperature as effectively as older children and adults. The Lullaby Trust also advises that overheating can increase the risk of Sudden Infant Death Syndrome (SIDS), which is why keeping babies comfortably cool is so important.
What's the Ideal Bedroom Temperature?
Aim for a room temperature between 16°C and 20°C for babies. Of course, during a UK heatwave this can feel almost impossible. Don't panic if the room creeps above this range. Instead, focus on helping your child stay comfortable by adjusting clothing, bedding and airflow. A room thermometer can be useful for monitoring the temperature in your child's bedroom.
How to Keep Bedrooms Cooler
A few simple adjustments can help reduce heat build-up:
Keep curtains or blinds closed during the day to block direct sunlight.
Open windows to let any air circulate (if its safe to do so)
Open internal doors to encourage airflow around the house.
( top tip - if you have any attic, open the hatch to this during the day and doors/windows open downstairs and it can help cool upstairs down a little )
If using a fan, ensure it is not blowing directly onto your baby. (also acts like white noise so you get 2 for the price of 1)
Move your child's cot away from radiators, heaters or windows receiving direct sunlight.
Remember that bedrooms upstairs often become much warmer than rooms downstairs, so it may be worth considering a temporary change of sleeping location during very hot weather.
What Should My Baby Wear to Bed?
One of the most common questions I hear during a heatwave is:
"Can my baby sleep in just a nappy?"
The answer is yes.
If the room is very warm, babies may be comfortable sleeping in just a nappy. As temperatures increase, fewer layers are usually needed. The Lullaby Trust recommends checking your baby's chest or the back of their neck to assess their temperature. Hands and feet often feel cool and are not a reliable guide. If your baby's skin feels hot, sweaty or clammy, remove a layer of clothing or bedding.
Helping Toddlers and Older Children Sleep Better
The same principles apply to older children.
Try:
Lightweight cotton short sleeved/pants pyjamas.
Cotton bedding rather than synthetic fabrics.
A cooler bath before bedtime, cools and soothes and also gets rid of that sticky sun cream feel from the daytime.
Plenty of fluids throughout the day. You may find they want more for extra hydration.
Keeping bedrooms dark during the day to prevent heat build-up.
Some children may naturally sleep later or wake more during particularly hot weather. This is completely normal and usually settles once temperatures return to normal.
Staying Hydrated
Hydration becomes especially important during hot weather. Younger babies may feed more, this is fine!
For older children:
Encourage regular drinks throughout the day.
Offer water-rich foods such as melon, cucumber and strawberries.
Ice-lollies are great for cooling down and extra hydration.
Keep a water bottle accessible at all time.
A Final Reassurance
If sleep feels a little messy during a heatwave, you're not doing anything wrong.
Just like adults, children often find it harder to sleep when they're too warm. Focus on keeping your child comfortable, dressing them appropriately for the temperature, and following safe sleep guidance.
The heat won't last forever, and once temperatures begin to drop, sleep often improves naturally again. For babies, always follow safer sleep guidance from The Lullaby Trust and NHS, and remember: a baby who is comfortably cool is much more likely to sleep safely and peacefully.
