Many people believe that a slightly open window promotes better sleep. Fresh air seems to be relaxing and create an immediate sense of well-being. However, many health experts recommend closing the window at night. This habit can present risks that are often underestimated.

Closing the window doesn’t mean sacrificing air quality. There are other solutions to ensure restful sleep and protect your health.

Risks to health and sleep quality:
Sleeping with the window open exposes you directly to temperature fluctuations. These sudden changes can disrupt your sleep cycle. Your body reacts to every draft of cold air and struggles to maintain a stable temperature. As a result, your sleep becomes lighter and less restorative.

Outdoor air also carries allergens such as pollen and dust. These particles can cause sneezing, irritation, and respiratory discomfort. For sensitive individuals, this can be enough to disrupt an entire night’s sleep. Sleep experts recommend limiting this exposure, especially during spring and fall.

Noise pollution is another problem. An open window lets in outside noise. A passing car, a loud voice, or a siren is enough to disrupt sleep. Even a simple nighttime awakening can affect overall sleep quality and increase fatigue upon waking.

Some people sleep more soundly when they feel safe. An open window can cause psychological discomfort. This sensation, even if mild, affects relaxation and delays sleep.
