Common Causes of Bedroom Mould

We can usually find mould in kitchens and bathrooms. Because of this, many people are surprised to hear that it can also be found in their bedrooms. A mouldy bedroom becomes a substantial source of exposure to health hazards if you obtain the required seven to nine hours of sleep. Because it can cause a variety of health issues, it’s critical to understand the reasons or causes of mould growth.

But let’s learn first: What is MOULD?

Moulds are fungi that can be found both indoors and outdoors. They spread by releasing minute spores into the air, which move to new locations. Those spores are continually travelling in the air and surroundings. However, when they land in a suitable water source, they begin to grow.

The relationship between mould and sleeping

Your bedroom could appear to be clean and neat. Yey, a variety of variables can turn your haven into the perfect breeding ground for mould. It can develop in a wide range of materials, especially porous and natural ones like cardboard, paper, wood products, wallpaper, insulation and ceiling tiles.


Mould, in addition to the numerous health issues, can bring along sleep disruption. Household moulds are linked to increased sleeplessness, snoring, and excessive daytime sleepiness in one major investigation. People who reported mould scents at home also reported greater rates of sleep problems, according to another study of nearly 5,000 adults. Furthermore, indoor moulds have been linked to allergic rhinitis. According to new research, this condition can induce a variety of sleep issues such as insomnia, restless sleep, obstructive sleep apnea, and snoring.

What are the causes of bedroom moulds?

Water Sources, Humidity, and Condensation

  • One of the main causes of mould is steam. Usually, bedroom mould is caused by condensation and continuous humidity (e.g. from weather conditions). Although the humidity level in this area may not be as high as in the other rooms, it can still grow.
  • Another issue if high humidity levels, or a lot of moisture. This can happen due to insufficient ventilation. It can grow in even little amounts of moisture. Condensation and wetness are most likely to occur in areas of your bedroom with limited airflow, such as under furniture and within closets.
  • Leaks in the roof, windows, pipes, or regions of flooding can all lead to concealed moisture in the bedroom, which can lead to mould growth. If water is spilled and not dried within 48 hours, it might grow.
