Understanding TOG Ratings: What New Parents Need to Know
What Is a TOG and Why Does It Matter for Babies?
TOG stands for “Thermal Overall Grade.” It’s a measurement that shows how warm a sleeping bag will keep your baby. The higher the TOG, the warmer the sleeping bag. Choosing the right TOG sleeping bag is critical for your baby’s safety and comfort at night.
- TOG helps prevent overheating or chilling.
- It guides you in choosing proper sleepwear and room settings for your baby.
How TOG Ratings Affect Baby’s Sleep Safety and Comfort
Babies can’t regulate their body temperature as adults do. A sleeping bag with the wrong TOG can increase risks, like overheating or waking up cold.
- Proper TOG ratings can lower risks of SIDS (Sudden Infant Death Syndrome).
- Right TOG helps your baby have longer and safer sleep.
Matching TOG Sleeping Bags to Your Baby’s Room Temperature
Decoding Room Temperatures and Climate Zones (With 2026 Updates)
Room temperature is essential when selecting the TOG. Many modern homes have smart thermostats, but room temperatures can still fluctuate. Here’s what you need to know:
- Below 16°C (61°F): Consider highest TOG (3.5).
- 16°C–20°C (61°F–68°F): 2.5 TOG typically recommended.
- 20°C–24°C (68°F–75°F): Use 1.0–1.5 TOG.
- Above 24°C (75°F): Always opt for lowest TOG (0.2–0.5).
How to Measure and Adjust Nursery Temperature Year Round
- Use a room thermometer designed for nurseries.
- Check temperature daily, both day and night.
- Keep crib away from direct sunlight and vents.
- Adjust heating or cooling as needed for your climate.
