Health and welfare concerns from Stachybotrys, individual species of Aspergillus, Penicillium, Chaetomium, Trichoderma, Phoma, and Fusarium are of great interest in the classification of harmful or black mold.

Many types of black mold are harmful and produce harmful materials that are especially harmful to people with chronic conditions. High concentrations of mycotoxins can lead to poisoning even in healthy individuals, depending on the concentration, duration of mold exposure, and various other factors.

What is mold allergy?

While many molds and fungi do not pose a health or wellness hazard, there are some molds that can cause serious allergic reactions, including anaphylactic shock, which can be serious.

The most typical times when mold allergies are at their optimum are the months between July and the early fall months, but because mold can thrive throughout the year, mold allergies can occur all year round. Most types of mold and fungus become dormant in cold weather but become active again when spring arrives, starting the period of mold allergy. In cases of mold allergy, there is an overreaction of the body’s immune system where a person inhales the mold spores, causing the person to cough, itchy eyes, and make it difficult for the person to perform activities. It also creates breathing problems for some people, especially those with a known diagnosis of asthma.

If you are allergic to mold, your immune system overreacts when you ingest mold spores. A mold allergy can cause coughing, itchy eyes, and various other symptoms that make you miserable. In some people, mold allergy is associated with asthma, and exposure causes breathing difficulties and other respiratory symptoms.

If you are allergic to mold, the most effective defense is to minimize direct exposure to the types of mold that are causing your reaction. Medications can help control mold allergy reactions.

Signs of mold in your house

There are several subtle signs that indicate that your home may have harmful mold.

1. Strange smell from the air conditioner or heater

If you think your heater or air conditioner has an unusual smell, you might want to check it out.

A stand-alone air conditioner is one of the main places where mold starts to grow. These devices are dark, damp, and often exposed to warm temperatures when not in use. If you put your air conditioner in a warm place in winter, this also increases the risk of mold.

Regularly check the condition of the air conditioner and clean it every two years.

2. The seams between the bathroom tiles have become dark

When you take a shower, pay attention to the seams between the tiles. If they are dark, it is most likely mold. Luckily, this type of mold is not that dangerous.

However, if your bathroom has been leaking recently or flooding an adjoining room, you may be dealing with a more toxic type of fungus that will be harder to remove.

3. Wallpaper starts peeling off

While wallpaper may discolor or wear out over time, wallpaper peeling is not normal. If the wallpaper bubbles or cracks, this indicates the presence of moisture on the walls. And moisture is a precursor to mold.

Pay attention to walls and any areas that look damp or warped.

4. Your cold won’t go away

Symptoms of a mold reaction may be subtle. It can be a common runny nose or bouts of sneezing. If you feel like your cold has dragged on, this could be a hidden sign of a mold problem.

If you have previously had breathing problems that suddenly worsened after a long break, mold may be the cause.

Most types of mold do not bother those who do not have respiratory diseases but immediately aggravate the symptoms in people suffering from asthma.

7. Itching appeared

Do you feel like your clothes are itching? Many people know that mold can grow in dark, damp places, but they don’t know that it can live on your clothes.

This is especially true for wet clothes. If you’re used to leaving wet towels on the floor or drying clothes on a rack in your home, mold will start to grow in the fibers of the fabric, leading to skin irritation.

To prevent this, always dry wet clothes as soon as possible and don’t pile wet towels in the bathroom.

8. Your seasonal allergies are not going away.

If the season is long past and your seasonal allergies continue, mold is a likely cause of your never-ending runny nose or cough.

Symptoms of mold exposure mimic or exacerbate an existing seasonal allergy. If symptoms improve during the day when you are at work and worsen in the evening at home, this could be a mold allergy clue.

9. Musty smell

If you notice an unusual musty smell in your house, even after you have cleaned and washed everything, you need to check your house more carefully for mold.

To understand that a strange smell is mold, and not just a long break between cleaning, pay attention to whether the smell intensifies in certain places or even corners of the apartment. If the carpets are cleaned, the curtains are washed, and you threw out the garbage on time, it could be mold.

10. You always feel tired

Toxic mold affects everyone differently, and one reaction to it can be to feel tired. If you find it hard to wake up in the morning and find yourself constantly drowsy throughout the day, mold may be the source of your problem.

11. Leak in the bathroom or toilet

Any flooding almost guarantees the development of mold. Most people don’t know that even a small overflow of water in the bathroom or constantly leaking pipes creates all the conditions for the spread of mold.

Prolonged exposure to mold can lead to more severe effects such as:

  • Hair loss
  • Anxiety and depression
  • Memory loss
  • Number of hands and feet
  • Stomach ache
  • Sensitivity to light
  • Overweight for no apparent reason
  • Muscle cramps
