This is the ideal air temperature for a good, healthy sleep

Some factors can affect sleep, and one of them is the temperature in the bedroom.

One study found that body temperature decreases during the so - called night stage and increases during the wake.

Lowering your temperature in your room several hours before bedtime may begin your body cooling process, which can help you sleep.

“optimal sleep temperature is considered to be 18.3 degrees Celsius”, said Ellen Vora, a psychologist and sleep expert.

In spring and autumn, you can do this by opening windows. You can use a wine fan.
