When the weather gets hot, setting the right air conditioning (AC) temperature is important for your baby’s comfort, safety, and sleep quality.
Meta Description:
Wondering how many degrees to set your AC for your baby? Learn the ideal temperature range (68–72°F) to prevent overheating and ensure safe sleep.
Why the Right AC Temperature Matters for Babies
Keeping your baby’s room at the optimal temperature is crucial for:
✔ Safety – Reduces SIDS risk (overheating is a known factor).
✔ Comfort – Helps baby sleep longer and more soundly.
✔ Health – Prevents dehydration, heat rash, or chills.
Ideal Air Conditioning Temperature for Babies
Recommended Range: 68–72°F (20–22°C)
Newborns & Infants: Slightly warmer (70–72°F / 21–22°C).
Active Babies/Toddlers: Can tolerate cooler (68–70°F / 20–21°C).
Pro Tip: Use a standalone nursery thermometer (not just the AC display) for accuracy!

5 Key Tips for Using AC Safely with Babies
Dress Baby Properly
For 68–72°F: Light cotton onesie + 1.0–2.5 TOG sleep sack.
Avoid heavy blankets, hats, or swaddles in AC.
Check for Overheating
Touch baby’s neck or back – Should feel warm but not sweaty.
Signs of overheating: Flushed cheeks, rapid breathing, damp hair.
Optimize Airflow
Avoid direct AC drafts (use a deflector or place crib away from vents).
Use a fan (on low, pointed away) to circulate cool air.
Control Humidity (40–60%)
Too dry? Use a cool-mist humidifier.
Too humid? Run a dehumidifier to prevent mold.
Save Energy Without Sacrificing Comfort
Daytime: Set AC to 74°F (23°C) when baby is awake.
Nighttime/Naps: Lower to 68–72°F (20–22°C) for better sleep.
Common Mistakes to Avoid
❌ Setting AC too cold (<65°F) – Can make baby uncomfortably chilly.
❌ Overbundling in AC – Increases overheating risk.
❌ Ignoring humidity – Dry air can irritate baby’s skin and airways.
FAQs About AC & Babies
Q: Can a fan replace AC for babies?
A: Fans help but aren’t as effective in extreme heat. Use both for best results.
Q: What if my baby’s hands/feet feel cold?
A: Cold extremities are normal—check the chest or neck for true body temp.
Q: Is 75°F (24°C) too warm for a baby?
A: It’s at the upper limit—watch for sweating or restlessness.
