Light, temperature and noise directly affect sleep
Windows are places that are directly affected by the external environment, including light, temperature and sound. When placing a bed right under the window, the body is easily affected by these factors, especially at night and early morning.
Natural light, even at a low level, can still affect the circadian rhythm, the mechanism that regulates the sleep-wake cycle of humans. Light passing through the window early in the morning can cause you to wake up earlier, disrupting deep sleep.
According to Dr. Matthew Walker - a neuroscience and sleep expert at the University of California, Berkeley (USA), "quality sleep depends on a stable environment, especially lighting and temperature control in the room". This shows that placing a bed under a window can reduce the ability to maintain a continuous sleep.
In addition, temperatures near windows often fluctuate more frequently than other locations in the room. This change can make it difficult for the body to maintain a deep sleep state. Noise from traffic, wind or external environments can also easily penetrate through windows, disrupting sleep that many people do not realize.
Health effects and reasonable arrangement
Not only sleep, the position of the bed under the window can also affect respiratory health. Air from outside carries dust, bacteria or pollutants, especially in urban areas. When sleeping near the window, the possibility of exposure to these agents will be higher.
According to Professor Alan Hedge - an environmental health expert at Cornell University (USA), "air quality in the bedroom directly affects long-term health, especially the respiratory and cardiovascular systems". Therefore, it is necessary to limit direct exposure to airflow from outside during sleep.
In addition, positions such as near doorways, under bars or facing strong light sources are also not recommended because they increase nerve stimulation, making it difficult for the body to relax completely.
The solution proposed by experts is to place the bed in a position that is less directly affected by the environment, prioritizing the area close to the wall to create stability. In case it is necessary to place it under the window, thick curtains, soundproof glass should be used and ensure closed doors at night to reduce external impact.
In summary, bed arrangement should be based on scientific principles of lighting, temperature and air quality. A stable sleeping space will help improve health, enhance sleep quality and daily living performance.
