What is the ideal air temperature in the bedroom?
Several factors can affect sleep and one of them is the temperature in the room where you sleep.
A study found that the body temperature decreases during the so-called night phase of sleep and increases during the waking phase.
Lowering the temperature in your room a few hours before bed can start the process of cooling your body, which can help you sleep.
The optimal temperature for sleeping is considered to be 18.3 degrees Celsius.
In spring and autumn you can achieve this by opening the window. While in summer you may need air conditioning.
