In general, it is not recommended to have a room without a window for safety and ventilation purposes.
No, you can't. According to Section R310 of the International Building Code (and most other building codes), every bedroom needs an operable window that can act as a second means of egress during an emergency—so landlords can't count windowless rooms as bedrooms.
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.
It's very dangerous to sleep in a room with no proper ventilation. Too many things can go wrong. You can be suffocated, have migraines, catch some airborne diseases, and the list goes on...
Keeping your bedroom dark not only helps you get a good night's sleep, but may significantly lower your odds of developing three major health problems, a new study suggests.
Since natural and artificial have a negative impact on a good night's sleep and sound health, it's easy to surmise that sleeping in a dark room can improve health outcomes and sleep quality by regulating the production of melatonin. Synchronizing your body's natural sleep-wake cycle can potentially prolong your life.
Effects on overall health
Fresh air does not enter and stale air is not removed to the outside. The consequences are: Increased risk of respiratory diseases such as asthma and allergies. Increased risk of developing respiratory problems.
“A fresh supply of oxygen is important to a good night's sleep,” Coplin says. As you sleep in a closed room, your body converts the oxygen in the room to carbon dioxide, slowly but persistently increasing the levels of CO2 in the air, explains Coplin.
Closing doors and windows do not significantly affect the oxygen level, especially for areas that are not properly sealed.
Sleeping with an open window can negatively impact your health as well. While cold air itself can't make you sick — colds and flus occur because germs overwhelm a person's immune system — it can potentially dry out nasal cavities, resulting in increased mucus production and a possible sinus infection.
The International Building Code requires every bedroom contains at least one egress window that is 5.7 square feet, at least 20 inches wide by 24 inches high with an opening no higher than 44 inches from the floor.
Effects of Poor ventilation can lead to a buildup of indoor air pollutants, triggering respiratory problems and allergies. Additionally, it hampers cognitive function, as increased carbon dioxide levels affect concentration and decision-making.
Windows are an essential design element in any space, as they are responsible for letting in light and fresh air, while providing views of the outside world. From the style of window to its placement, windows serve more than just a practical element.
While it's often associated with a natural change in weather and sometimes referred to as “the winter blues,” a lack of natural light in an office can produce similar effects on employee mental health that can ultimately affect employee satisfaction, emotional wellbeing, and job performance.
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.
One of the best and quickest ways to get your oxygen saturation up is by letting them get fresh air. 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.
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.
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.
Closing your bedroom door provides benefits like reducing noise, ensuring privacy, and enhancing safety by keeping potential intruders out. On the flip side, leaving the door open is reported to naturally make hot weather more bearable, thanks to better airflow.

Your indoor air can be dangerous and unhealthy, especially if your living space has poor ventilation. Stale air exposes your household to allergens and irritants, leading to respiratory complications, illness and allergic reactions.
Research shows sleep can be disrupted by temperatures anywhere below 65 degrees Fahrenheit or above 75 degrees Fahrenheit. But for most people, heat interferes with sleep more than cold does. Sleep experts believe the best temperature for great sleep is between 68-72 degrees Fahrenheit.
