Ideal Nursery Temperature
Creating the perfect sleep environment for your baby
Pediatric note: The American Academy of Pediatrics recommends 68-72°F (20-22°C) for newborns to reduce SIDS risk.
Why Room Temperature Matters
Babies, especially newborns, can't regulate their body temperature as effectively as adults. Research shows:
- Overheating increases SIDS risk by up to 4.5 times
- Newborns lose heat 4 times faster than adults
- Temperature fluctuations disrupt sleep cycles
- Proper temperature supports healthy weight gain
Key fact: A baby's room temperature is more critical than outdoor temperature since they spend 16-20 hours/day sleeping.
Recommended Temperature Ranges
Newborns (0-3 months)
Key Considerations:
Very sensitive to temperature changes, need consistent warmth
Recommended Dressing:
Onesie + swaddle or sleep sack
Infants (3-12 months)
Key Considerations:
Can tolerate slightly cooler temps as they grow
Recommended Dressing:
Footed pajamas or wearable blanket
Toddlers (1-3 years)
Key Considerations:
More active, can overheat if too warm
Recommended Dressing:
Light pajamas + light blanket if needed
Temperature Extremes to Avoid
Overheating
Warning Signs:
- Sweating
- Damp hair
- Flushed cheeks
- Rapid breathing
- Heat rash
Risks:
Increased SIDS risk
Action: Remove layers, lower temp by 2-3°F
Too Cold
Warning Signs:
- Cool chest/back
- Pale skin
- Fussiness
- Reduced activity
- Cold hands/feet (normal)
Risks:
Disrupted sleep, hypothermia risk
Action: Add layer, increase temp by 2-3°F

When to Seek Medical Help
| Symptom | Urgency Level |
|---|---|
| Baby feels hot to touch with fever | Call pediatrician immediately |
| Room temperature below 60°F (15°C) | Use safe heating methods immediately |
| Persistent sweating despite cool room | Medical evaluation needed |
| Blue lips or extremities | Emergency care required |
Adjusting Room Temperature
Cooling the Nursery
- Use blackout curtains during daytime
- Place a bowl of ice before a fan (out of reach)
- Open windows at night if safe
- Use breathable cotton sheets
- Run AC on low with indirect airflow
Warming the Nursery
- Use a space heater with auto-shutoff (3+ feet from crib)
- Install thermal curtains
- Place a hot water bottle in crib 30 mins before bedtime (remove before baby)
- Use wool or fleece sleep sacks
- Add a humidifier for dry heat
Safety note: Never place heating/cooling devices near crib. Maintain 3-foot clearance from all baby equipment.
Common Parent Questions
Q: How can I accurately measure nursery temperature?
Place a digital thermometer at crib level, away from windows/heaters. Smart monitors can track trends.
Q: Is it better to err on warmer or cooler side?
Slightly cooler is safer than too warm. Overheating is a greater SIDS risk factor than being slightly cool.
Q: How does room humidity affect temperature comfort?
Ideal humidity is 40-60%. Dry air feels cooler, humid air retains heat. Use a humidifier if needed.
