The ideal temperature for sleeping well: between 16 and 18°C.

Tips for a restful sleep:

Avoid hot showers before bed.
Wear socks or use a hot water bottle if you are cold.
Don’t tuck your bed in too much to let your body breathe.
Where does the 19°C rule come from? A standard to be questioned?

While the 19°C figure is now a standard, it originated in the 1970s, during the oil crisis.

At the time, this measure was aimed at reducing energy consumption, but homes were less well insulated than they are today.

With advances in thermal insulation and energy management, is this rule still relevant?

19°C or 20°C: what is the ideal temperature for good comfort?

According to Nick Barber and Brad Roberson, energy and heating experts, 19°C is an arbitrary temperature that may not suit everyone.

Their recommendation?

20°C is a better compromise between thermal comfort and controlled consumption.

Why choose 20°C?
At 19°C, some people still feel a sensation of cold, especially when standing still.
At 20°C, we avoid shivering while maintaining reasonable energy consumption.
For the bedroom, it is better to choose 16 to 18°C.
