What about Mildew?

We’ve discussed mold in the home fairly extensively, but what about mildew? Well, mildew is usually light in color and appears as a surface layer on moist areas, like bathroom walls. Mold is usually darker and can penetrate deeper into materials, often causing more serious damage to structures and belongings.

Still, mold and mildew can both cause troubles in the home, so it’s important to keep an eye out for both.

What Is a Black Mold?

“Black mold” is not a specific type of mold per se, but the term is usually used to refer to Stachybotrys chartarum. Sometimes people use the terms “black mold” or “toxic mold” to talk about molds that might make harmful substances called mycotoxins. Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. View source

When mold produces mycotoxins, it can cause a spectrum of health issues when inhaled or in contact with the skin. Molds that make mycotoxins are also called toxigenic fungi.

The common symptoms of black mold toxicity include respiratory issues, skin rashes, eye irritations, fatigue, and headaches. The most common habitats of black mold are moisture-damaged buildings and areas with high humidity, as it likes places with prolonged moisture exposure.

How Does Mold Affect Human Health?

Here’s how the toxins produced by molds affect human health.

Allergic Reactions

Many individuals are allergic to mold and can experience sneezing, runny or stuffy nose, itching and watery eyes, skin rashes, and wheezing. In some cases, mold exposure can exacerbate Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. View source asthma symptoms, regardless of whether or not the person is allergic to mold.

Respiratory Issues

Neurologic Changes

“Fungi is one of the types of microorganisms associated with the interconnection between the nervous system and the gastrointestinal tract called the ‘gut microbiota,’” explains Antrell Cheatom. “ Recent research Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. View source is showing us that imbalances could indirectly lead to disability by being involved in neurologic disease and mood regulation.”

Is Sleeping in a Room with Mold Safe?

If you have mold in your bedroom or even mold in your mattress, sleeping there can induce multiple health concerns. The presence of mold will alter the ambiance of your bedroom. Plus, you will sense a musty odor, making the environment unsuitable for the rest of the day’s long hours.

Furthermore, your body’s defense mechanism is in the resting phase while you are asleep. It makes you more vulnerable to the adverse effects of mold or mildew.

All of these factors will affect the quality of your sleep. Plus, a study found Verified Source ScienceDirect One of the largest hubs for research studies and has published over 12 million different trusted resources. View source a correlation between mold and increased sleep problems like insomnia, obstructive sleep apnea, and daytime sleepiness.

“Severe complications can arise if an immunocompromised person is exposed to a large inoculum of mold and left untreated,” says Antrell Cheatom. “The pathophysiologic mechanism behind the mold causing disseminated disease in the nervous system is not totally understood.”

“However, Aspergillus mold provides some pathway as to how mold exposure can increase symptom severity. Aspergillus produces a specific mycotoxin Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. View source called aflatoxin B1. Humans are exposed via oral intake of nuts, seeds, and grains. This toxin becomes problematic to humans when the liver metabolizes the compound, leading to cardiopulmonary crises, aspergillosis-related brain abscesses, and hepatocellular carcinoma.”

“It is crucial to consult your local physician if you suspect that you or a loved one is experiencing unusual symptoms upon being exposed to mold.”

How Does Mold Grow in the Bedroom?

Mold doesn’t need a lengthy list of environmental conditions to be checked off to grow. It can easily grow in a damp, moist place that hasn’t been cleaned up after a splash of water, a burst pipe, or floodwater. Conditions that can easily happen, say, in basement bedrooms that haven’t been flood-protected.

Mold is capable of growing on a variety of materials like wood, cotton, cardboard, paper, wood product, and ceiling tiles. It can also grow inside the wallpaper and insulation. In the bedroom, mold can also gain a foothold with a water-damaged mattress.

Another factor that contributes to mold growth is poor ventilation. Bedrooms with poor ventilation can trap the moist air, creating a humid environment conducive to mold growth.

This happens in rooms where windows are seldom opened or where airflow is restricted — which is how we usually keep our bedrooms.

Bedroom temperature and darkness also facilitated mold growth. The temperature range that we find comfortable to sleep in (60°F and 80°F), mold thrives in it.

How Fast Can Mold Grow in the Bedroom?

The speed at which mold grows in the bedroom can vary depending on various factors. Mold growth requires moisture and a suitable surface to thrive on. When these conditions are met, mold can start growing within 24 to 48 hours. The exact timeline can differ based on the type of mold, the amount of moisture present, and the temperature of the environment.

Once mold spores find a damp or humid area in the bedroom, they can quickly start reproducing and forming colonies. Within a few days to a couple of weeks, you may begin to notice visible signs of mold growth, such as discoloration or dark spots on surfaces like walls, ceilings, or even your mattress. If left unchecked, the mold can continue to spread and multiply, leading to larger and more extensive infestations.

This is why it’s crucial to address any signs of mold growth promptly to prevent further spread and potential health risks. Regularly inspecting your bedroom for signs of moisture or water damage, ensuring proper ventilation and maintaining air quality, and promptly addressing any leaks or spills can help prevent mold growth and keep your bedroom healthy.

If you suspect mold in your bedroom, it’s advisable to take immediate action to identify and remove the source of moisture. It’s best to seek professional help or consult with a mold remediation expert, rather than try to tackle the project on your own and miss any mold growth.

How To Control Mold Growth In Bedrooms?

Controlling mold in the bedroom is essential to maintain a healthy environment. Here are some ways you can follow to control mold growth in bedrooms.

Maintain Humidity

You need to keep your bedroom’s humidity levels in check. A relatively high humid environment is known to cause an increase in wakefulness and a decrease in Slow Wave Sleep (SWS), REM sleep, and sleep efficiency.

The moist environment in the bedroom with high temperatures disrupts the heat loss mechanisms during sleep, affecting sleep quality. The same moist temperature makes your bedroom more susceptible to mold growth.

You can maintain your bedroom’s humidity levels between 30% and 50% with the use of dehumidifiers. In case of spills or leaks, address the matter promptly and ensure wet areas are dried within 24-48 hours.

Improve Ventilation

Regularly open doors and windows of your bedroom to allow fresh air to circulate, especially when you are engaging in water-related activities inside your bedroom. Sleeping with a fan on can also improve circulation and keep you cool at night.

You can use exhaust fans to maintain Verified Source National Library of Medicine (NIH) World’s largest medical library, making biomedical data and information more accessible. View source the overall ventilation system or ceiling fans to enhance airflow.

Regular Cleaning

Your sleeping sanctuary should be cleaned regularly. Vacuum and dust your bedroom weekly using a HEPA filter vacuum to capture mold spores. Or save yourself some work with an air purifier that has a HEPA filter to capture spores and other allergens.

Wash sheets and other bed linen in hot water at least once a week and make sure to dry them in the sunlight.

Inspect for Leaks

You need to check for signs of water damage or leaks in the ceiling, walls, and around windows. For example, if your mattress is wet underneath, investigate why. If left unaddressed, escaped water from leaks and such will capture mold spores for growth.

Also, make sure the exteriors of your home — especially the roof and gutters — are in good condition and not leaking.

Keep Plants in Check

Install indoor plants that keep the bedroom’s environment clean and refreshing. Bedroom plants that need ample amounts of water to grow will stay moist for a prolonged time. This persistently moist soil will become a host of molds.

Many indoor plants don’t require that much water to stay alive. This is because they hardly receive any sunlight to evaporate the excess moisture.

Avoid Overcrowding

If you place furniture and other items closely, it will overcrowd the room. It is best to keep your things at a distance for adequate air circulation. This will prevent moisture from trapping in and providing a mold-friendly environment.

Other symptoms may include headaches, fatigue, dizziness, and skin rashes. The symptoms of mold sickness can also exacerbate the symptoms of any other medical condition you have.  If you suspect mold sickness, it’s best to consult a healthcare professional.

Where can mold hide in a bedroom?

Mold can be hidden in various places in your bedroom. It tends to grow in areas with moisture or high humidity levels. Some common hiding spots for mold in a bedroom are damp carpets, behind wallpaper or drywall, under the mattress or furniture, inside closets, and in poorly ventilated bathrooms attached to the bedroom.

It’s important to regularly check these areas and address any signs of mold promptly.

When does mold grow in the bedroom?

Mold in the bedroom can grow at any time of the year. That said, certain seasons may contribute more to its growth, as mold thrives in damp and humid conditions. The warmer months of spring and summer tend to have higher humidity levels, which can promote mold growth. Preparing your bedroom for summer should include mold prevention in wetter climates.

However, we must note that mold can still develop in the bedroom during other times of the year. If there are factors like moisture accumulation or poor ventilation, you are more likely to find mold flourishing. Therefore, it’s essential to maintain a clean and dry environment in the bedroom throughout the year to prevent mold growth.

Do air purifiers help with mold in the bedroom?

Yes, air purifiers can help with mold in the bedroom. Air purifiers equipped with HEPA filters can capture mold spores from the air, reducing their concentration and improving indoor air quality.

However, it’s important to note that air purifiers alone may not solve the root cause of mold growth. It’s essential to identify and address the source of moisture or humidity in your bedroom to prevent mold from recurring.

What kills mold spores in the air?

The benefits of air purifiers with HEPA filters include capturing bedroom mold spores from the air and reducing their concentration, along with keeping other allergens under control. UV-C light can also kill mold spores, and some air purifiers are equipped with this feature to minimize their presence in your home. Regular cleaning and maintaining indoor environments also eliminate airborne spores.

Do dehumidifiers remove mold?

Though they don’t directly help you in mold removal, dehumidifiers prevent its growth and proliferation by restricting the conditions it requires for growth. Mold needs a certain level of moisture to grow. Dehumidifiers reduce moisture levels in the air, creating an environment where mold struggles to thrive

By maintaining an optimal humidity level (usually between 30% to 50%), you can create a less favorable environment for mold. However, it’s important to fix any leaks or sources of moisture to prevent mold growth effectively. Regular cleaning and proper ventilation are also essential in mold prevention.

Conclusion

Mold is a silent intruder that can grow where it finds favorable growth conditions. Mold in the bedroom can open the door to numerous health problems.

Though you can not directly work on ‘removing mold’ or get rid of the already-grown mold, you can make your bedroom an unfavorable habitat for it.

In addition to the tips shared above, you can install a hygrometer to monitor the humidity levels and maintain it to a degree where mold growth is unlikely to happen. You can also try renovating your bedroom with mold-resistant drywall or paint, and look into mold-resistant mattresses and other bedding.

Mold growth in the bedroom can become a cause of weakened immune systems. It also affects sleep problems like sleep deprivation, excessive snoring, and sometimes is behind sleep-disordered breathing.
