Sleeping habits and environment affect both mental and physical health. We’ve heard about sleep cycles and hours and how and when you fall asleep, but are there other factors in the way you sleep? What is the effect of the ventilation of the bedroom on sleep health?
Sleeping in a room with little or no ventilation will lead to bad air quality, an imbalance of humidity, and multiple health issues. Sleep quality will be diminished, and there is an increased risk of allergies or sensitivities over time.
In the rest of this article, we will discuss the effects of poor ventilation on air quality, housing conditions, and physical health. We will also look at how ventilation affects humidity, the dangers of high and low humidity, and how to ventilate a room overnight properly.
1. Poor Air Quality
When fresh air doesn’t circulate regularly, the air in the home becomes heavy in carbon dioxide and low in new oxygen. This isn’t immediately toxic but can lead to health problems for the inhabitants of the house.
In addition to causing problems for the people sleeping there, low air quality will affect the house’s structural integrity. Stale air can’t get released and remains in the unventilated bedroom. Recycling the old air and trapping it within the home will cause fluctuations in humidity.
2. High Humidity Levels
With low air quality, humidity can get trapped in the house. If the house’s humidity levels remain higher than usual, then the walls or the insulation within the walls will be damp. Mold is likely to grow. There are many ill effects of living in a house with mold in the walls.
Prolonged exposure to high humidity can lead to many health conditions, including skin conditions such as eczema and nervous system damage and even cancer or lung disease. Poor ventilation is not the only cause of high humidity and mold, but it could contribute.
3. Low Humidity Levels
Similar to having high humidity levels, inadequate ventilation could cause low humidity. Dryness in the air can get trapped without fresh circulation. As such, this can lead to dry skin and dehydration, especially throughout a night of sleep.
4. Poor Sleep Quality
The most common physical symptom of sleeping in a room with poor air circulation is the lack of quality sleep. The lack of fresh air and oxygen can interrupt the sleep cycle and cause insomnia, inadequate sleep, or even sleep apnea.
Lack of sleep can lead to other health problems but is most often seen in fatigue and lowered energy levels. Perpetual tiredness affects people’s performance, productivity, and emotions negatively and can have a lasting effect on mental health. Sleeping with a window open might not solve all of these problems, but it could bring better sleep quality and higher energy levels.
5. Mental Focus and Performance
Because of the lack of adequate sleep and oxygen, the brain can suffer from low ventilation. A person experiencing fatigue will not be able to focus well or do high levels of mental work. Fresh air and sleep are essential for brain functionality and focus.
Extended lack of sleep and fatigue can also lead to mental health issues, such as depression and anxiety. A good sleep schedule is vital to many aspects of health, and proper ventilation is essential for healthy sleep.
6. Heightened Risk of Allergies and Sensitivities
Especially in houses with dampness or mold issues, poor ventilation can add to the risk of allergies or sensitivities. Sensitivities to the air can take the form of perfumes, dust, or spores, and these can be intensified by dampness, mold, or even a buildup of bacteria in the air (all caused by poor ventilation).
Low oxygen levels affect the brain in several ways, not just mental performance or mood. Poor air quality can lead to headaches, whether occasional or chronic. Headaches are often caused by environmental factors, such as vitamin deficiencies or lack of fresh air. A common cause is insufficient sleep levels, which can be affected by air quality.
8. Nausea and Dizziness
The buildup of bacteria in the air, lack of fresh air, and poor air circulation can cause dizziness and nausea. Lack of sleep and headaches, which are also symptoms of inadequate ventilation, can lead to nausea over an extended period.
9. Sick Building Syndrome
Sick Building Syndrome is a common name for the symptoms that come from living or working in a building infected with something. These symptoms can be mold, bacteria, or low air quality. All of these symptoms can increase. If everyone who lives in the house feels these (or other chronic disorders stemming from the air quality), Sick Building Syndrome is the outcome.
Sick Building Syndrome is mostly caused by the office or work buildings but occasionally can happen in domestic situations. If there is one room in the house that is predominantly affected (such as the bedroom), then only the people who spend larger amounts of time in that room might be affected by Sick Building Syndrome.
How to Properly Ventilate a Bedroom
There are several options for adequately ventilating a bedroom, even if you like to sleep with your bedroom door closed. Sleeping in a well-ventilated room will be much better for your health and happiness than a stuffy and dry bedroom. Here are some ways to get air flowing more efficiently:
- Ensure that your vents are open
- Sleep with the window cracked
- Leave the bedroom door open
- Turn on box or ceiling fans
- Air out your room
- Make sure that your walls are properly insulated
If you do one or more of these action items, you should be able to feel a difference in your sleep quality and the staleness of the air. If the problem still persists after all of these are complete (or you sleep in a room with no windows or outside walls), you may want to move rooms or get the insulation checked out for sealing issues.
Sleeping in a Room With No Ventilation: Final Words
Little or no ventilation leads to low air quality in bedrooms and houses. This can lead to damage in the home itself, both through humidity levels and contaminant buildup. It can also lead to problems sleeping and multiple health issues.
While many people sleep in a room with lower air ventilation than is ideal, very few people sleep in a room with no vents. If you sleep in a basement room with no windows and no vents, it is vital to keep the air flowing somehow. Usually, it is also essential for both legality and safety reasons to have a way to escape from the bedroom in case of emergency.
Lack of ventilation can cause some issues within the framework of your house. The absence of a regular flow of fresh air (especially in newer places, which are more airtight and sometimes at a higher risk of low ventilation) causes the air inside the house to stagnate and humidity levels to fluctuate.
In addition to these effects on your house and bedroom, poor ventilation can lead to several different health conditions. Whether it is due to low air quality or varying humidity levels, sleeping with a lack of fresh air is detrimental to health and sleep quality.
With a lack of ventilation, the stale air builds up. This includes carbon dioxide and air bacteria. It can lead to a slew of health problems, which start small but can build on each other and cause moderate to severe issues over time.
