Finding the right indoor temperature is key to ensuring comfort, maintaining health and reducing energy costs. According to building thermic specialists and public health guidelines, the ideal temperature varies slightly depending on the room and how the home is used.
Forget 19°C / 66°F. You need to adapt. Not every room is the same. Ideal Temperature for Living Areas first : For living rooms, lounges and dining spaces, the ideal temperature is 19 to 21°C (66 to 70°F). This range provides optimal comfort while keeping energy consumption under control, as heating one extra degree can increase energy use by roughly 7%.

Bedrooms: Cooler Is Better
Science is clear: people sleep better in cooler rooms. The ideal bedroom temperature for adults is 16 to 18°C (61 to 64°F).
For children’s bedrooms, 18 to 19°C is recommended, especially for infants.
Kitchen, Bathroom and Other Spaces
The kitchen can comfortably remain at 18-19°C, as cooking naturally generates heat.
The bathroom is the exception: for a comfortable start to the day, it can be heated up to 22°C (72°F) during use.
Why Temperature Matters
Overheating a home dries out the air, leads to fatigue and poor sleep, and dramatically increases energy bills.
A home that is too cold encourages humidity, condensation and respiratory issues.
In Summary
- 19–21°C (66–70°F) for living areas
- 16–18°C (61–64°F) for bedrooms
- 18–19°C (64–66°F) for the kitchen
- 22°C (72°F) in the bathroom during use
Maintaining the right temperature balance ensures comfort, good health and lower energy costs — the perfect trio for any modern home.
