Your home contains millions of dust particles, germs, and pathogens. But by opening your windows and increasing ventilation, you'll significantly improve your indoor air quality. It's so effective in fact, the CDC recommends improving ventilation in your home as one way to reduce virus particles.
Studies have shown that fresh air blowing in from outside has a profound effect on the air quality in the home. Opening a window helps purify the indoor environment, reducing the buildup of stale air, odors, and pollutants. Scientists have discovered that indoor air is far more contaminated than outdoor air.
In addition to dry air, sleeping with the window open can expose you to allergens that can be easily inhaled during sleep, notes Dr. Laren Tan, a pulmonologist and director of Loma Linda University Comprehensive Program for Obstructive Airway Diseases.
The practice is known as lüften ("ventilate" in English) and involves opening the windows of your home every day in order to ensure that there is an exchange of air: the stale, dirty indoor air goes out and is replaced by fresh air from the outdoors.
Closed windows allow pollutants such as dust, mold, and allergens to accumulate, leading to the circulation of stale air. Without fresh air entering your space, the immune systems of individuals in the home may become compromised due to prolonged exposure to harmful indoor pollutants.
How, then, to keep your IAQ A-OK? Prevailing wisdom is that at least 5 minutes—and ideally 15 to 20 minutes—a day of ventilation significantly improves indoor air quality. For a strong ventilation, open the front and back door, along with windows on the path in between, to get the baddies out.
The exhaust fans will push stale air outside, while fresh air is drawn in through the open windows. The only problem with this method is that it will cost more to heat your home in winter since you will lose warm air and have to heat the cold air that comes in through the open windows.
He traces the two-door house back to the combined dwelling house and animal stall—sometimes called a “housebarn” or Wohnstallhaus — which existed in every Germanic area of Europe in the first millennium. At first there were separate entrances to the animal stalls and the dwelling portion of these large houses.
European tilt-and-turn is a type of window design that allows for two distinct opening positions: tilting or turning inwards. The tilt function enables the top portion of the window to tilt inwards at the top, providing gentle ventilation.
Did you know In Irish tradition, every door and window is opened at midnight on New Year's Eve. This isn't just about letting the old year go-it's a way to welcome the spirits of departed loved ones, inviting them to join the celebration and blessings of the New Year.
'Ideally, we want to position ourselves with a nice solid headboard for support,' says Patricia. 'A window is not solid. It is quite flimsy and could break easily, allowing someone to potentially break the glass at night. ' This lack of support could also lead to things falling through in your life, some experts claim.
Sinus Infection: We are more likely to contract sinus infections while sleeping with windows open at night, especially in drier climates. Trigger Asthma: Pollen particles travel into our homes through insects and open windows. Pollen falls closer to the ground when the air is cooler.
An open door helps increase airflow and regulate a bedroom's temperature. If your door needs to be closed, consider opening a window instead – even in winter and even if it's just a crack. “Waking up from overheating is a common problem that can cause a disrupted night's sleep,” says Swain.
Something as simple as opening your windows or heading outdoors for a walk can effectively increase the amount of oxygen you breathe in, which in turn increases your overall blood oxygen level.
Opening windows early clears out humidity and stale air built up during the night and infuses our homes with freshness. In general, outdoor air is less polluted before 10am or after 9pm. Be sure to make use of these times, and open windows that don't open onto the street.
15 minutes is enough to air the house properly
A window open for 15 minutes is enough! That's it. With this method, only the indoor air will be cooled.
Lüften involves opening windows in order to air out a space and improve air circulation, replacing stale indoor air with fresh outdoor air. This can improve air quality in the room and keep the air from getting too dry.
French Doors are full length and feature a door handle, whereas French windows are half length and have a different handle specifically manufactured for windows. French windows feature two panels of glass that are side hung and open either inward or outward, creating an uninterrupted view.
Living close to the sea gives us strong winds (often with rain), a window turning outward is better for keeping the wind out. An inward turning window is a bit like a funnel that lets the wind (and rain) in.
One Door Was Formal, the Other Was Not
It's obvious, but two doors might have been in place to provide separate entrances to the home, opening to different spaces. While one door may have led to a formal area, the other could have been used for day-to-day business.
So the coffin door is basically a side door that they would use to bring the body into the house for the wake, then carry out again for the funeral. It has no exterior handle as it is meant to be opened from inside.
German windows and doors are designed with two panes that are insulated between the frames. Each pane of glass has a slight lip on the inside of it to help with ventilation as well as prevent elements like rain and snow from entering the room.
Among survey respondents, there was no noticeable difference in amount of sleep, sleep latency, or sleep disorders among people who slept with windows and doors open versus closed. “Our study suggests that bedrooms should be ventilated with clean outdoor air.”
Cooking/showering
When cooking, open a window or use an extractor fan to let steam out. To reduce steam, keep a lid on saucepans as you cook. Open a window or use an extractor fan after a bath or shower and close the door so the moist air goes out of the window and not into the rest of your home.
One of the most significant concerns for those sleeping in a room without windows is the air quality. Without proper ventilation or access to outdoor air, your space becomes more susceptible to humidity, allergens, and potentially harmful airborne chemicals.
