The ideal nursery temperature for a newborn is between 68-72°F (20-22°C), with 70°F (21°C) being the optimal target. Maintaining this temperature range reduces the risk of Sudden Infant Death Syndrome (SIDS) and helps your baby sleep safely and comfortably.
Keep your newborn's nursery between 68-72°F (20-22°C) for safe, comfortable sleep. Most experts recommend 70°F as the ideal temperature. This range is cool enough to prevent overheating—a major SIDS risk factor—while warm enough that your baby won't become too cold. The key is consistency: aim for steady temperatures rather than fluctuating between hot and cold.
Newborns cannot regulate their body temperature as efficiently as older children and adults. They're vulnerable to both overheating and getting too cold, which is why precise nursery temperature control is crucial for their safety and comfort.
Why Temperature Matters: Research has consistently linked overheating to increased SIDS risk. When a nursery is too warm, babies may overheat during sleep, which can lead to fatal breathing complications. Conversely, a room that's too cold can cause discomfort and sleep disruptions. The sweet spot of 68-72°F minimizes these risks while promoting quality sleep.
Seasonal Considerations: In summer, use air conditioning or fans to maintain proper temperature. In winter, use heating systems but avoid space heaters, which can create temperature hotspots and pose fire hazards. Window treatments can help regulate temperature naturally by blocking excess heat or cold.
Bedding and Clothing Impact: Temperature works in conjunction with bedding and sleepwear. A cool room (70°F) should be paired with appropriate sleep clothing—typically a sleep sack for infants rather than blankets, which are SIDS hazards. This combination helps prevent overheating while keeping your baby warm.
Individual Variations: While 68-72°F is the recommended range, some babies may sleep better at the slightly warmer or cooler end depending on their personal preferences. However, never exceed 75°F, as this significantly increases SIDS risk. Monitor your baby's cues: if they're sweating, have flushed cheeks, or seem restless, the room may be too warm.
The American Academy of Pediatrics (AAP) emphasizes temperature control as part of their safe sleep guidelines. They recommend keeping the nursery at a comfortable temperature to reduce SIDS risk, though they don't specify an exact degree. The National Institute of Health and Care Excellence (NICE) specifically recommends maintaining a room temperature between 16-20°C (approximately 61-68°F), though most pediatricians in North America suggest the slightly warmer 68-72°F range to account for different climates and home designs.
Pediatric sleep specialists note that consistency is more important than the exact temperature. A room that stays at 70°F throughout the night is safer than one that fluctuates between 65°F and 75°F. This consistency helps regulate your baby's sleep cycles and reduces the stress on their developing thermoregulatory system.
A reliable nursery thermometer is essential for monitoring and maintaining the ideal temperature. Rather than guessing or relying on your home's general thermostat, a dedicated nursery thermometer gives you precise, real-time readings of your baby

← Back to All ReviewsThe ideal nursery temperature for a newborn is between 68-72°F (20-22°C), with 70°F (21°C) being the sweet spot recommended by pediatricians. This temperature range helps regulate your baby's body temperature without overheating, which is a risk factor for SIDS. Most experts agree that keeping the room slightly cool is safer than warm.
A cool nursery is better for a newborn than a warm one, as overheating increases the risk of SIDS (Sudden Infant Death Syndrome). Babies regulate their temperature through their head and face, so a cooler room allows them to shed excess heat safely. You can always add layers like sleep sacks or blankets to keep your baby warm if needed.
Check your baby's neck or back—if it feels sweaty or clammy, the room is too warm; if it feels cold to the touch, the room needs to be warmer. You can also look for signs like flushed cheeks, rapid breathing, or restlessness (too hot) versus shivering or low temperature readings (too cold). A simple room thermometer makes it easy to monitor the exact temperature.
A programmable thermostat is the safest way to maintain consistent nursery temperature, but a space heater or AC unit can work if kept away from the crib and used safely. If using a space heater, ensure it has automatic shutoff features and keep it at least 3 feet from the crib to prevent burns and fire hazards. Never place heating pads or heating blankets directly in the crib.
