Summer nights with a baby? Here's how to keep things cool

Summer might be in full swing, but nights where you wake up sweating - even while lying still- are no fun for anyone. Let alone for a baby who can't yet regulate their body temperature. A hot night and a baby who needs to sleep? You're in the right place for safe and cooling tips.

Sound familiar? Tossing, turning, one leg out from under the covers. Sure, summer has its charm - but on hot nights, falling asleep can be a real struggle. That’s because our bodies need to cool down before we can drift off. And that goes for babies, too. The difference? While you might get by on a little less sleep, your baby really needs those hours to grow and develop.

Dress right for dreamland. It might feel counterintuitive not to tuck your baby in fully, but on warm summer nights, less is more.

Pay attention to the TOG rating (Thermal Overall Grade), which indicates how insulating a piece of clothing is. It helps you keep your baby cool and prevents sweating during sleep.

Recommended TOG values by room temperature:

Below 16°C : 3.0 TOG
16–18°C : 2.5 TOG
18–22°C : 1.5 TOG
22–24°C : 1.0 TOG
Above 24°C : 0.5 TOG

🛈 This is only a guideline. Always check your baby for signs of overheating. Also important: add up the TOG values of all layers your baby is wearing. For example, a 0.5 TOG bodysuit + a 1.0 TOG summer sleeping bag = 1.5 TOG total.

Create the ideal sleep environment

Clothing isn’t the only factor, your baby’s surroundings matter too. Since TOG ratings are based on room temperature, here’s how to keep the nursery as cool as possible:

• Keep windows and curtains closed during the day – Block out sunlight and warm air by closing blinds or shutters. This prevents the room from heating up and creates a cooler, safer sleep environment for warm nights.

• Air out the room late in the evening – Only open windows once the outdoor temperature has dropped, usually around 10 or 11 PM. Be mindful of light, noise, and insects. Blackout curtains, white noise, and a mosquito net can make a big difference. 

• Use fans and AC wisely – Air conditioning is fine for cooling the room before bedtime, but avoid running it all night, as it can dry out the air. A fan can stay on, as long as it’s out of reach and not blowing directly on your baby.

Adjust your routine

During a heatwave, tweaking your evening routine can help. A quick lukewarm bath before bed helps cool your baby’s body. Is it really hot upstairs? Consider temporarily sleeping together in the coolest room of the house. Whatever helps your baby sleep comfortably through the summer.

Know the signs

Some sweating during sleep is normal, but if your baby has a red face or seems unusually restless, they may be too warm. Fun fact: crying actually raises body temperature. Try to soothe your baby, remove a layer, or cool the room further.

A layer of air is the smartest solution

Your baby’s ultimate summer sidekick? The AeroSleep 3D Mattress Protector. This clever extra layer fits right over your favourite mattress and creates a cushion of air between your baby and the bed.

Thanks to its unique honeycomb 3D structure, it promotes optimal air circulation, helping heat and moisture escape, so your baby stays dry and cool, even on warm nights.

No more damp backs: just a dry, comfortable sleep environment. And that means better sleep. For everyone. The 3D mattress protector doesn’t just offer cooling comfort, it also provides peace of mind. Even if your baby rolls onto their tummy, they can still breathe freely. That’s safe sleeping for summer, night after night.

The result? A well-rested baby, and peace of mind for you!
