Too Hot to Sleep? How to Help Your Baby, Toddler or Child Sleep in Hot Weather

Hot, sticky nights can make bedtime feel much harder for both children and parents. If your baby, toddler or child is struggling to settle, waking more often, or seeming uncomfortable during warm weather, this is very normal.

We all sleep best when our body temperature can naturally drop slightly as we prepare for sleep. When the bedroom becomes too warm, this cooling process can be disrupted, making it harder to fall asleep and increasing the chances of night waking.

As a responsive sleep consultant, I know that changes in sleep can feel exhausting and overwhelming for families. Hot weather can temporarily disrupt even the most settled sleepers, but gentle adjustments can help your child feel more comfortable while they sleep.

When the bedroom starts feeling more like a greenhouse than a sleep space, bedtime can become a challenge! While we can’t change the weather, gentle adjustments to the sleep environment, clothing and bedtime routine can support your baby, toddler or child to feel a little more comfortable during warmer nights.

Why hot weather affects sleep

As we fall asleep, our body temperature naturally decreases. A warm bedroom can interfere with this process, which may lead to:

• Difficulty settling at bedtime

• More frequent night waking

• Restlessness and discomfort

Babies and young children can be especially sensitive to heat, as they are less able to regulate their body temperature compared with adults.

How to keep the bedroom cool

During the day, try to keep heat out of the bedroom by:

• Closing curtains or blinds to block direct sunlight

• Keeping windows closed during the hottest part of the day

In the evening, once the outside temperature begins to drop:

• Open windows to allow cooler air in

• Create airflow by opening windows on opposite sides of the home where possible

A fan can help circulate air and make the room feel more comfortable. Place it safely away from your child’s reach and avoid pointing it directly at them, especially towards their face.

If the bedroom is still extremely warm, consider moving your child to a cooler room if this is possible. During periods of very high temperatures, keep an extra eye on babies and young children, as they can become affected by heat more quickly than adults.

Bathing before bed

A bath before bedtime can help children feel more comfortable on hot nights. Use water that feels comfortable and slightly cooler than usual, but avoid making it cold, as this can be unsettling.

If the weather is exceptionally hot and your child is struggling to settle, you can use a tepid damp cloth to gently wipe their forehead, neck or arms to help them feel more comfortable before sleep.

What should your child wear to bed?

On very hot nights, some children may be comfortable sleeping in just a nappy or a very light layer, depending on their age and the room temperature.

Toddlers and older children may only need lightweight clothing or a single thin layer.

Remember that children can become cooler later in the night, as body temperature naturally drops after the early hours of the morning. Avoid overdressing, as overheating can make sleep more difficult.

Safe sleep for babies

Always follow safer sleep guidance for babies:

• Place your baby on their back to sleep

• Keep the sleep space clear

• Avoid pillows, duvets and loose bedding

• Use appropriate clothing and bedding for the room temperature

Helping your child settle in hot weather

Warm weather can make cuddles and settling more difficult, especially when both parent and child feel hot and uncomfortable.

A tepid damp muslin cloth placed between you can help reduce that sticky feeling during bedtime cuddles or night wakes. You can also gently wipe your child’s forehead, neck or arms to help them feel fresher and more comfortable without making them too cold.

Drinks and feeds

Make sure children have access to enough fluids throughout the day, especially during warmer weather.

Toddlers may need reminders to drink or benefit from having water easily available. Breastfed babies may want to feed more often during hot weather, both for comfort and hydration.

Keep bedtime routines familiar

Even when the weather is uncomfortable, keeping your child’s usual bedtime routine can help them feel secure and ready for sleep.

Keeping things consistent can make it easier for children to settle, even when the temperature is not ideal.

Why sleep may be worse in summer

It is very common for children to:

• Wake more often during the night

• Take longer to fall asleep

• Wake earlier in the morning

This is usually temporary and improves once temperatures become cooler. However, if sleep continues to feel unsettled once the heat has passed, it may be a sign that your child’s needs have changed. As your child grows, develops and moves through new stages, their sleep needs change too, and sometimes the support they need changes with them.
