It is better to close the windows when night falls. It is worth doing this even when it is summer outside with its high temperatures.
It would seem that fresh air helps you fall asleep, but experts are sure that this is just a misconception.
Why you shouldn't leave windows open at night
A 2020 study by the Johannes Gutenberg University Mainz found that the habit of leaving windows open at night can have negative health effects.
The thing is that, according to scientists, traffic noise at night has a strong impact on well-being.
Even in a dream, a person perceives all these sounds – at the subconscious level.
This recommendation is especially relevant for residents of houses located near the road – here the noise level is several times higher.
Loud sounds can disrupt the body's internal clock (the so-called circadian rhythm), which regulates the functioning of internal organs and metabolic, functional and biological processes.
Research shows that short sleep or sleep interruption due to street noise increases the risk of developing cardiovascular disease in the future. Noise can also raise blood pressure and increase stress hormones. Lack of sleep can cause mental health problems such as anxiety and depression.
