Sleeping in our homes
Another factor which ranks highly is how good and sound asleep we are sleeping in our homes. The importance of sleep for health is of course great, but it also influences our performance. But what we do with the trapped air that we have in our bedroom?
Sleep better in the dark and noise-free rooms
Most of us would agree that we sleep better in the dark and noise-free rooms. A new Danish study shows that even the air quality affects the quality of sleep. The study was admittedly quite small but gave clear results.
In the survey healthy people in ages of 20-30 were sleeping in rooms with different air quality. The difference in air quality were obtained by three different degrees of ventilation:
1) closed bedroom window (almost no ventilation) – resulting in poor indoor air quality
2) bedroom window ajar – which gave good air quality
3) closed windows with mechanical ventilation, which gave good air quality
Sleeping better with good air quality provided by ventilation
In the last case of mechanical ventilation subjects were asleep fastest, were the most alert and felt better the next day.
An interesting observation was made that despite the fact that air quality was about the same in cases 2) and 3), the quality of sleep and next day´s performance was lower for those who slept with the window slightly open. The conductors of the test believed that this is likely due to the disrupted traffic and perhaps other sounds from outside.
