The quality of a child 's or baby 's sleep depends on many factors: bedding, light, noise… but above all, the room temperature . Excessive heat can cause frequent awakenings, while excessive cold can be detrimental to the comfort and health of young children.

In this comprehensive guide, we'll explain how to maintain the ideal temperature in a child's bedroom , both in summer and winter, to ensure restful and safe sleep . You'll find answers to frequently asked questions:

• What temperature is best for a child's bedroom at night?

• What indoor temperature is too cold for children?

• How can I tell if my child is cold at night?

Why is bedroom temperature so important for children's sleep?

Babies' and children's sleep is particularly sensitive to variations in ambient temperature . Unlike adults, their body temperature is less easily regulated, and they are therefore more vulnerable to temperature fluctuations in the room , especially infants .

• An overly hot environment can lead to excessive sweating, dehydration, and restless sleep.
• An atmosphere that is too cold exposes one to the risk of colds, chills, and discomfort.
• An ideal temperature , combined with good bedding, helps to reduce nighttime awakenings.

What temperature is best for a child's bedroom at night?

Experts agree on an optimal range: the optimal temperature for a child's bedroom at night is between 18 and 20 °C .

• For a baby under one year old, it is advisable to keep the temperature close to 18°C , in order to avoid any risk related to excessive heat.
• For an older child, temperatures up to 20°C can be tolerated, especially in winter if heating is necessary.

This ideal temperature range promotes peaceful sleep , reduces the risk of nighttime awakenings, and helps the body maintain a stable core temperature .

What temperature is suitable for a bedroom in winter?

In winter, the temptation is strong to overheat a child's environment . However, excessive heat should be avoided. Ideally, the room should be kept between 18 and 19°C , even if it is very cold outside.

Some practical tips:

• Use a sleeping bag appropriate for the season rather than a loose blanket, in order to keep the baby warm without risk of suffocation.
• Opt for breathable clothing such as a bodysuit or cotton nightwear depending on the Celsius temperature recorded in the room .
• Monitor the humidity level : during the winter months, heating dries out the air. The ideal level is between 40% and 60% for the child's comfort and respiratory health .

What indoor temperature is too cold for children?

Below 16°C in the bedroom , the ambient heat becomes uncomfortable, or even too cold for a child.

• Sleep may be disrupted by frequent awakenings.
• The child may show obvious signs of being cold : cold hands, shivering, crying at night.
• The risk of illness increases if the body has to constantly fight to maintain its body temperature , especially in infants .

Tip: If you're staying in a poorly heated home, opt for a warm sleep sack and long-sleeved pajamas . However, avoid layering too many clothes, as this can restrict breathing or cause overheating.

What temperature is suitable for a bedroom in summer?

While winter requires controlled heating, particularly for energy consumption, summer often necessitates combating excessive heat . When the room temperature exceeds 22°C , a baby's sleep can be disrupted.

Tips for refreshing the bedroom:

• Open the windows of the house early in the morning and late in the evening.
• Avoid letting in direct sunlight during the day; use shutters or blackout curtains.
• Dress the child more lightly: a short bodysuit , thin pyjamas or even just a light sleeping bag .
• If the temperature exceeds 24°C, opt for a TOG 0.5 sleeping bag for your infant or simply leave the child in a bodysuit.

What temperature is best for a teenager's bedroom?

Much is said about the optimal temperature for a baby's or child's room , but teenagers shouldn't be neglected, as their sleep remains essential for growth and health . Their needs are similar to those of adults, but certain precautions are necessary:

• The ideal temperature for a teenager's bedroom at night is between 18 and 20 °C .
• A room that is too hot can lead to difficulty falling asleep, sweating and restless sleep .
• A room that is too cold (less than 16°C) can disrupt the regulation of body temperature and cause nighttime awakenings.
• The humidity level remains important, ideally between 40% and 60% , to avoid throat irritation and promote smooth breathing.

For teenagers, it is also advisable to:

• Opt for suitable bedding (a quality mattress provides better support for a growing spine) (for example, the Bamboo Hybrid mattress is a very good choice for a teenager).
• open the windows in the room every day.
• Limit screen time before bedtime to promote restful sleep .

A good bed and a suitable mattress make all the difference during this crucial period. Discover our range of beds, bed bases, and mattresses, designed to support every stage of sleep, from childhood to adolescence.

How can I tell if my child is cold at night?

Babies cannot clearly express their discomfort. It is therefore essential to know how to recognize the signs :

• The hands and feet are cold to the touch.
• The child wakes up frequently and seems agitated.
• The skin may be slightly mottled (a sign of cold ).

Helpful tip: touch the back of the baby's neck rather than their hands. If the neck is warm and dry, the temperature is ideal . If it's damp, the baby is too hot.

How to regulate the temperature of the room according to the environment?

To guarantee the optimal temperature , there are several simple solutions:

1. Air the room daily to refresh the air and adjust the humidity level . Depending on the windows in your house, you can adjust their ventilation. This will also help you optimize your energy consumption.
2. Install an indoor thermometer to monitor room temperature and humidity levels .
3. Use an adjustable heater with a thermostat to maintain a constant temperature and optimize your energy consumption.
4. Dress the baby according to the Celsius degrees measured in the house: short or long sleeve bodysuit , cotton pyjamas , suitable sleep sack .
5. Arrange the baby's room optimally: avoid direct sources of heat near the bed , do not place the crib against a cold exterior wall.

Clothing and sleeping bag: how to dress baby at night?

Choosing the right nightwear is essential for regulating the bedroom temperature :

• 18°C : long-sleeved romper + cotton nightwear + TOG 2 sleeping bag.
• 20°C : short-sleeved romper + light nightwear + TOG 1 sleeping bag.
• 22°C : light romper + thin sleeveless sleeping bag.

Avoid adding a loose blanket to the crib for safety reasons. A sleep sack remains the safest and most comfortable option.

The role of humidity levels in the room

We talk a lot about temperature , but humidity plays an equally crucial role. Air that is too dry causes:

• throat irritations,
• night awakenings,
• dry skin.

A humidifier can help regulate the optimal humidity level between 40% and 60% . This parameter is often overlooked, but it greatly contributes to sleep quality .

Common mistakes parents make regarding house temperature

Many parents think they are doing the right thing, but make mistakes that harm babies' sleep :

• Overheating the room in winter with a radiator that's too powerful.
• Using too many layers of clothing and a thick sleep sack causes overheating.
• Place a fan heater directly in the baby's room .
• Forgetting to air the room daily and not opening the windows of the house enough.
