Open windows in summer heat can affect sleep quality and cause health risks such as high blood pressure.
Close the window: This is how rest at night protects your health”
Nighttime temperatures are rising and many people in Munich are opening their windows in the hope of being able to sleep better during these summer nights. However, a current study by researchers at Johannes Gutenberg University Mainz shows that this supposed solution could have health consequences. The research highlights the importance of synthetic sleep conditions and the dangers of noise at night.
The influence of noise pollution on sleep
Researchers have found that noise, particularly caused by traffic, not only disrupts sleep patterns, but can also cause long-term health problems. Even if the refreshing breeze is pleasant, the noise around the open window can stress the body. In particular, stress hormones can be released in excess, which has a negative impact on blood pressure and general cardiovascular health.
The risks to general health
The results of the study are alarming: disrupted sleep due to noise at night can significantly increase the risk of cardiovascular disease. The negative effects include:
- Erhöhter Blutdruck
- Steigende Stresshormonlevel
- Eine verstärkte Steifheit der Blutgefäße
The human ear remains active during sleep and also subconsciously perceives sounds, making complete recovery almost impossible. Experts therefore recommend closing the window or taking measures to reduce noise, especially at high temperatures, in order to counteract impaired well-being.
Mental health under pressure
In addition to physical health risks, the researchers point out that mental illnesses, such as depression and anxiety disorders, may also occur more intensely. A disturbed night's sleep often leads to the development of negative emotions, which are also seen as a result of noise in the open air. The World Health Organization (WHO) has made clear recommendations: Nocturnal noise levels should be below 40 dB(A) to avoid health-endangering effects.
Caution is advised
Given the risks described above, it is important to realize how crucial a quiet environment is for a good night's sleep. Aside from traffic noise, other disruptive factors, such as a snoring partner, can also have a negative impact on sleep. Closing the windows seems to be one of the easiest solutions to protect your health and guarantee a restful sleep during the warm season.
Conclusion: Sleep well despite the summer heat
The sleep study highlights that the convenience of an open window during hot nights can pose significant health risks. During the summer, people in Munich and elsewhere should weigh up whether the risk of noise is really worth it compared to the need for cool air. Considering the health consequences, it may be advisable to resort to alternative strategies for cooling bedrooms.
Quickly changing your sleeping environment, such as moving the bed or using earplugs, can help improve your night's sleep without having to open the windows.
