Foreword

Have you ever heard the saying \”You must close when you sleep at night\”? Many people may think this is superstition or even unnecessary, but in fact, there are many scientific principles behind this habit.

This small action may actually affect our sleep quality. However, this is not only a psychological effect, but what impact does the door have on our sleep?

If you think it\’s for peace of mind, it\’s a big mistake. Before going to bed tonight, try closing the bedroom door to see what different changes you can find from it.When you come back, why does the door need to be closed?

Why is it closed

In modern urban life, sleep quality has become a problem that has troubled many people.

The living environment in the high-rise building seems comfortable, but there are various tumultuous factors.

Close the door to create an independent space. It\’s like putting a hidden protective cover on sleep.

The door panel can effectively block the sound of living room TV, floor speaking, and even the sound of late-night elevator running.

This physical isolation not only reduces noise stasis, but also reduces the scattering of light and helps the brain enter a resting state faster.

Study shows that even weak environmental noise can cause a decrease in sleep quality, and the sound of the engine of a car, the laughter of a neighborhood, and even the buzzing sound of the refrigerator at night. These seemingly tiny sounds accumulate to severely stimulate the deep sleep stage.

Close the upper bedroom door to create an environment close to sound insulation, allowing the brain wave energy to naturally turn into the slow-wave sleep stage, and improve the sleep repair function.

Safety protection

Many people may not know that closing the bedroom door is not only for peace and tranquility.

In the event of a fire, a closed door can prevent the flame from spreading and the smoke from spreading to fight for escapeThe precious time.

In addition, closed doors can reduce room temperature by ten degrees and reduce the invasion of toxic gases.

This seemingly simple action is actually setting up a barrier for life safety.

When fire occurs, smoke is more deadly than flames, and smoke containing multiple toxic gases is the main cause of most cases of fire deaths.

Ordinary wood doors can provide about 20 minutes of buffering in the early stages of the fire, giving people the opportunity to be rescued or find escape routes.

Temperature adjustment

In the era of air conditioning, the temperature conditioning of the room has become an important topic in living.

Close the room to form a relatively independent temperature system to reduce the loss of cooling and heating.

In winter, the door can reduce heat loss and make the room temperature more stable; Summer can improve air conditioning efficiency, and can also gain a more comfortable sleep experience while reserving energy.

This precise control of temperature can allow the body to have sufficient rest in the most suitable environment.

Study shows that humans are most likely to get high-quality sleep in an environment of 18-20 degrees Celsius, and the temperature adjustment mechanism is closely related to sleep quality.

Open space will increase the temperature fluctuation amplitude, causing the air conditioning system to be frequently stopped. Not only increases energy consumption, it will also affect the depth of sleep due to the temperature fluctuations.

After every wave of the bedroom temperature, the human body may experience a short and mild awakening state, which will cause sleep fragmentation.

Close the microclimate area created by the bedroom door to reduce temperature fluctuation amplitude and help maintain a stable deep sleep state.

Protect privacy

In modern home life, the demand for personal space is increasingly valued.

Close the door to create a private rest environment, especially in multiple generations of living or shared housing.

This physical barrier not only protects personal privacy, but also creates a sense of security and makes people more psychologically relaxed. he helps improve sleep quality.

The sense of privacy and security are related to each other. Close the bedroom door, a simple action can activate the safety perception area in the brain and reduce the secretion of nerves under the warning state.

Lack of privacy can lead to long-term tension, making the parasympathetic neural system difficult to guide night physiological activities, and thus affecting the quality and duration of deep sleep stages.

Especially for adolescents and the elderly, having a controllable private space has important implications for mental health development and maintaining autonomy.

Enhance sleep quality

If you want to truly improve your sleep quality, it is not enough to just rely on the door.

The creation of a sleep environment requires many efforts.

Adjust work and rest time, establish a regular life rhythm; control indoor light and temperature; Choose suitable bedding; avoid using electronic equipment before going to bed; and exercise to relax your body and mind.

The optimization of these details, combined with the habit of sleeping, can comprehensively improve sleep quality.

Drinking habits in daily life are also important. Avoid irritating foods and drinks before going to bed, and choose foods that help you sleep, such as warm milk or honey water.

Also, the hardness of the bed and the body curve will directly affect the degree of spinal relaxation, and thus the quality of deep sleep.

The color of the bedroom should be adjusted to choose a cool color system. Blue and green can reduce heart rate and blood pressure, and naturally guide the body to enter a resting state.

Continuation

Sleeping around the door is a small habit, and it seems that it has a profound meaning.

It is not only related to our safety and privacy, but also an important part of improving sleep quality.

The points in life are worth our careful management, and we have started to develop the habit of sleeping in the door, so that we can enjoy high-quality sleep every night.
