If it's safe to do so, open doors and windows as much as you can to bring in fresh, outdoor air. While it's better to open them widely, even having a window cracked open slightly can help. If you can, open multiple doors and windows to allow more fresh air to move inside.
Lack of ventilation can lead to the buildup of indoor air pollutants, such as carbon dioxide and volatile organic compounds, which can have short-term effects, such as headaches, dizziness, and fatigue, and long-term effects, such as respiratory problems and increased risk of chronic illnesses.
Passive ventilation can be as simple as an open window or a vent in a wall that allows air to move in and out of the building. Passive ventilation does not require energy, but it can still have a cost.

Open Windows
If you are in a completely closed room, open some windows and let the fresh air fill the room. If you are feeling unwell in a well-ventilated room with many people in it, go close to the windows and breathe the air in. Once you get some fresh air into your lungs, you should feel better in a few minutes.
So changes would be even smaller in most homes. Simply put, humans don't take in as much oxygen as we think we do. Based on oxygen alone, estimates are that the average person could survive in a completely sealed, airtight room for 12 full days! Running out of oxygen in a room is quite unlikely.
Persistent Odors: Homes should refresh and clear out odors naturally through proper ventilation. If cooking smells, smoke, or other odors last longer than they should, it's likely your home isn't circulating air properly.
Q: What are some alternatives to ceiling fans for improving air circulation? A: Alternatives include floor fans, oscillating fans, and tabletop fans. They provide targeted airflow and can be used to complement ceiling fans or in rooms without them.
With insufficient ventilation, warm air lingers in summer, which can lead to overheating and the need for more cooling. In winter, a lack of ventilation can allow cold air to enter, requiring more heating. This results in a higher energy consumption for both heating and cooling, and consequently higher energy bills.
Cross ventilation (single spaces): Being unsophisticated and efficacious, this type of ventilation is a horizontal process that is driven by pressure differences between the windward and leeward sides of the occupied indoor environment.
Ventilation via a window
When rooms are ventilated via a window the fresh air and the spent air flow in and flow out through the same window. This is a customary way to ventilate and is the most generally practiced.
Aggravating Allergies
Fans can spread dust. View Source and other allergens around the room. For people with allergies, breathing in these allergens can impact the quality of their sleep. View Source .
Using fans while the windows and doors are open will get air moving even faster. Use a dehumidifier if the air feels and moist stuffy. If you're in the bathroom or kitchen, turn on the exhaust fan to get air moving. In the kitchen, you can also turn on the range hood fan (if you have one).
Symptoms caused by biological pollutants include sneezing, eye irritation, coughing, dizziness, and respiratory infections.
Health Implications of Poor Ventilation
Prolonged exposure to these airborne contaminants can trigger or exacerbate respiratory problems, such as asthma, allergies, bronchitis, and chronic obstructive pulmonary disease (COPD).
Consider using indoor fans in combination with open doors or windows to further increase ventilation. In addition to specialized window fans, box fans or tower fans can be placed in front of a window. Fans can face toward the window (blowing air out of the window) or away from the window (blowing air into the room).
Keep the doors open. Keeping the bathroom door open after using the bathroom is a great way to help ventilate the bathroom if there aren't any windows. This lets out any steam that has built up when you were taking a shower or a bath.
Sleeping with your bedroom door closed can help maintain your desired temperature, which is crucial for a restful night's sleep. In the summer, sleeping with your bedroom door closed can help keep the air conditioning in, while in the winter, it can help keep your bedroom warm and toasty.
Air conditioners are designed to produce and circulate cooled internal air from room to room. The air conditioner unit does produce additional oxygen. However, it can be attached to a special duct that provides fresh air from outside that will introduce additional oxygen into a building.
