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.
Sleeping in a room with no air ventilation can lead to a few key issues: poor air quality, high humidity, and lower oxygen levels. Over time, these factors can impact your health. Poor air quality can lead to respiratory problems and increased susceptibility to lung infections.
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.
After 3 to 5 minutes, hypoxia, or oxygen deprivation sets in, brain cells begin to die and you're on your way to being dead.

Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later.
15 minutes is enough to air the house properly
That's it. With this method, only the indoor air will be cooled. It will take just a few minutes to heat the room again. Leaving a tilt-and-turn window ajar all day, however, is not effective: it cools the walls and it costs much more to heat the room back up again.
"The air quality in the bedroom can affect your cognitive abilities, such as your ability to concentrate, to understand, and to react. Sleeping in a well-ventilated bedroom benefits your cognitive abilities,” says Pawel Wargocki.
Because there are no warning signs of reduced oxygen concentrations, these environments are extremely dangerous. Effects of exposure to low oxygen concentrations can include giddiness, mental confusion, loss of judgment, loss of coordination, weakness, nausea, fainting, loss of consciousness and death.
Indoor air is not replaced by fresh outdoor air. In most cases, air conditioners cannot perform ventilation. You must ventilate in another way.
Sleeping with your bedroom door closed is a practice that significantly improves your chances of surviving a house fire. According to the FSRI, closing your door can greatly decrease carbon monoxide levels from 10,000 PPM to 1,000 PPM when compared to leaving it open.
Without effective ventilation, this moisture can be trapped in the home and turn into condensation, particularly in the winter when surfaces such as walls are cold. The condensation can lead to damp and mould growth which can cause damage to your home and lead to respiratory illnesses for you and your family.
Open the door of the room to create cross-ventilation with your single window, pushing stale air out the room, and allowing more air to circulate throughout your home.
Lack of sunlight also hinders our ability to regulate our sleep-wake cycle, leading to imbalanced and irregular sleep patterns. Fortunately, there are a few different lighting solutions for windowless rooms that can help light even the dimmest, dreariest bedrooms.
The speed and degree of recovery from carbon-monoxide poisoning depends on the length and duration of exposure to the gas. The half-life of carbon monoxide in normal room air is four to five hours. This means that, in four to five hours, half of the carbon monoxide bound to hemoglobin will be replaced with oxygen.
Do you know how long does it take to ventilate a room? Experts say open your windows for at least five minutes a day for fresh air.
With poor ventilation in house, the hot air concentrated at your attic's highest points stays trapped. This, in turn, can lead to uneven roof temperatures (ice dams), an overtaxed HVAC (higher energy bills), and other costly headaches.
If ventilation is poor, airing rooms can improve it as a temporary measure while awaiting longer-term changes. Opening all the doors and windows as fully as possible maximises ventilation in a room. If it's too cold for the people in the room you can do this when they leave for a break.
While every space has its share of toxins that needs to be filtered or ventilated, buildup occurs if the air isn't circulating regularly. Fresh cleaner air is drastically important for everyone's health and well-being and the quality of indoor spaces.
Even when vascular collapse is the primary event, brain and lung functions stops next. The heart is the last organ to fail.
A low oxygen level in the blood can cause shortness of breath and air hunger (the feeling that you can't breathe in enough air). Your skin, lips, and fingernails may also have a bluish color. A high carbon dioxide level can cause rapid breathing and confusion.
However, in a life or death situation, there is another element that's just as important: oxygen. It's called the Rule of 3's, which states that you can go without food for three weeks, water for 3 days, but only three minutes without oxygen.
