Close the window at night when it's hot: This is how noise protects your health

Munich – One of the unexpected challenges of the summer heat is the question of how to get a restful sleep despite high temperatures. During this time, many people tend to open windows wide overnight to let in fresh air. However, a new study from Johannes Gutenberg University in Mainz suggests that this solution is not entirely healthy. Instead, closing the windows could lead to a better night's sleep.

Noise as a health factor

In their study, the research group found a clear connection between noise at night and the release of stress hormones. This has a significant impact on the human body. While opening the window may improve airflow, it disrupts sleep and increases the risk of cardiovascular disease. A restful sleep is crucial as it regenerates the body and promotes health.

Another look at night noise

Nighttime noises caused by traffic can particularly affect sleep. Waking up frequently or getting little sleep not only increases blood pressure, it can also lead to the development of serious cardiovascular diseases in the long term. The role of this noise is often neglected in consumer research. Nevertheless, the results clearly showed that the blood vessels can also be damaged by constant noise.

Mental health in focus

The problem of noise is not just limited to physical illnesses; Psychological problems such as depression and anxiety can also result. The immediate emotional reactions to noise are significant. The researchers note that negative emotions associated with noise at night cannot be ignored.

Practical tips for better sleep

To protect your health and promote healthy sleep, the researchers recommend keeping the window closed at night, even when temperatures are high. This can help minimize nighttime noise and improve sleep quality. Additionally, simple measures such as using earplugs or even moving the bed can help create a peaceful sleeping environment.

Public health guidelines

The World Health Organization (WHO) has published guidelines that address the lasting effects of noise at night on health. According to these recommendations, nighttime noise exposure should not exceed 40 dB(A) in order to minimize health risks. Adhering to these values ​​is critical to promoting better quality sleep.

Given the important findings of this study, it is clear that our nighttime environment has a significant impact on our health. The simple decision to close the windows at night could make a huge difference to our well-being and health.
