But what you face indoors may be even more damaging. Indoor air pollution, the degradation of indoor air quality by harmful chemicals and other materials, can be up to 10 times worse than outdoor air pollution. This is because contained areas enable potential pollutants to build up more than open spaces do.

Exposure to indoor and outdoor air pollutants may increase an individual’s risk for morbidity and mortality from a variety of different conditions in multiple organ systems. These exposures cause and/or exacerbate respiratory diseases and diseases in other organ systems.

This study showed that outdoor air pollution related to traffic emissions and wildfires significantly increased the indoor air pollutant concentrations due to infiltration and natural ventilation in the 28 low-income homes that were sampled.

Because there is not enough ventilation, concentrations of indoor air pollutants can build up from inside sources as they are not released into the greater outdoor expanse. The design of modern homes to reduce air leakage (with improved insulation) may also lead to lower air exchange between the indoors and outdoors.

Open windows and doors When outdoor pollutant levels are high, ventilating the indoors with outdoor air can make your pollution worse. It’s typically a good idea to regularly let in lots of outdoor air to decrease build-ups of indoor pollutants and toxic gases, such as ultrafine particles and carbon dioxide (CO2).

Health experts: Keep windows closed at night while air quality is in ‘unhealthy’ range. While it is tempting to want to open up a window and let in cool air at night, health officials said it might be just as harmful as standing outside.

Moderate. The AQI is between 51 and 100. Air quality is acceptable; however, pollution in this range may pose a moderate health concern for a very small number of indi- viduals. People who are unusually sensitive to ozone or particle pollution may experience respiratory symptoms.

When you air out the house, it prevents mold and humidity from forming, you rid the house of foul smells and also let out the excess carbon dioxide.” – “I open the windows to let out the foul air that accumulates in closed areas – smells and germs.

The shocking fact is that the air inside your home is generally between two and five times more polluted than the air outside, says the Environmental Protection Agency. Some factors can make indoor air up to 100 times more toxic than the outdoor environment.

What symptoms are often linked to poor indoor air quality?

• Dryness and irritation of the eyes, nose, throat, and skin.
• Headache.
• Fatigue.
• Shortness of breath.
• Hypersensitivity and allergies.
• Sinus congestion.
• Coughing and sneezing.
• Dizziness.

Read on for some tips on improving your indoor air quality without the use of chemicals.

1. Open Your Windows.
2. Spruce Up Your Décor With Houseplants.
3. Opt for Essential Oil Diffusers.
4. Opt for Beeswax Candles.
5. Take Your Shoes Off.
6. Keep Your Pets Groomed.
7. Run the AC.
8. Clean With Non-toxic Chemicals.

7 Common Indoor Air Pollutants

• (1) Pollutant: carbon monoxide (CO)
• (2) Pollutant: radon.
• (3) Pollutant: nitrogen dioxide (NO2)
• (4) Pollutant: secondhand smoke.
• (5) Pollutant: lead particles.
• (6) Pollutant: asbestos.
• (7) Pollutant: mold.

The EPA lists the four most dangerous indoor air pollutants in developed countries as cigarette smoke, formaldehyde, radioactive radon-222 gas, and very small fine and ultra fine particles.

Improving air quality

1. Keep it clean. A clean house may be a healthier house, because good indoor hygiene can greatly cut down on dust and animal dander, says Dr.
2. Keep the greenery outdoors.
3. Change your filters.
4. Invest in an air purifier.
5. Let the fresh air in.
6. Disclaimer:

Indoor pollution sources that release gases or particles into the air are the primary cause of indoor air quality problems. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources and by not carrying indoor air pollutants out of the area.

High air pollution levels can cause immediate health problems including: Aggravated cardiovascular and respiratory illness. Added stress to heart and lungs, which must work harder to supply the body with oxygen. Damaged cells in the respiratory system.

Common Causes of Poor Room Ventilation

• Smoke.
• Cooking and Heating.
• Housekeeping Supplies and Activities.
• Poor Building Construction and Design.
• Lack of Maintenance of Airconditioning Systems.
• Building Materials and Furnishings.

Little to no airflow filtering in and out of your room through windows can cause humidity to build up. In turn, stale air, high levels of humidity, and warm temperature can create a perfect environment for mold growth in your bedroom. Sleeping in an environment where mold is festering can be terrible for your health.

Poor ventilation will result in an eventual build up of carbon dioxide and little oxygen, which means you could suffer from shortness of breath, headaches and fatigue.

Prevent Poor Ventilation in the Home

1. Install a Ceiling Fan. Ceiling fans help circulate the air around your home.
2. Install a Heat Recovery Ventilator (HRV) Heat recovery ventilators circulate fresh air into your home.
3. Install Proper Attic Ventilation.

They say that poor or non-existent ventilation might cause attic temperatures to rise to 150 degrees or higher in the summer. That can lead to damaged shingles and other roofing materials as well as a buildup of condensation and development of mildew and mold.

It’s possible to have too much exhaust ventilation, but you cannot have too much intake ventilation. If there is more intake ventilation than the attic’s square footage requires, it’s not problematic because any excess intake converts to “exhaust” on the leeward side of the house.

Opening all of the doors in the room that lead to other spaces can significantly improve airflow. Even without fans, open doors allow fresher air in and fumes and stale air out. If you have doors that open to the outside and have screens, keeping these open even for 10 minutes can drastically improve ventilation.

Well, poor ventilation can have serious consequences. It can make our homes “sick”, with condensation and mould damaging the walls and fabric of our houses. But, more importantly, it can make the occupants sick.

Well, nothing to worry about for 5 to 6 hours. Trapped inside a sealed room? Then you have plenty of time… let’s explore later in this answer… so… GENERALLY when the Oxygen in the air you breathe drops below 10% then the person still get enough Oxygen pressure in to survive by breathing deep.

3 Ways to Keep a Room Well-Ventilated

1. Turn on Those Fans. Just because you run the air conditioner doesn’t mean you shouldn’t turn on your ceiling fan.
2. Open Interior Doors. Even if you don’t run your fans, opening all interior doors can allow air to circulate throughout the home.
3. Use a Box Fan on Occasion.

To ventilate a room without windows, you can use air bricks in the wall. You can also use them in small water closets. Either way, this is would help both in circulation of fresh air alongside having a comfortable temperature in the room.

7 ways to ventilate spaces without windows

1. An effective extractor fan. Save.
2. Air conditioning in the bedroom. Save.
3. Air-purifying plants. Save.
4. Have less furniture. Save.
5. Scented candles work wonderfully. Save.
6. Use porous materials. Save.
7. Hidden air bricks. Save.

How often should you air out your apartment? You should air out your apartment daily, between 15 and 30 minutes, because the air inside an apartment is often more polluted than the air outside. Your apartment will contain pollutants arising from cooking, household cleaning products, as well as mold and fungus spores.

If you don’t open any windows, the stale inside air will continue to fester in the room. The window doesn’t have to be completely open; even cracking it slightly will make a notable impact. In sum, the air around you when you sleep is more important than you might think.
