What is Mold Allergy Season? Symptoms and Solutions
If you have an allergy to mold, then the warmer months can be difficult. As the weather warms up and humidity rises, so does mold growth. In fact, molds thrive in moist and humid environments.
Mold allergy season typically peaks during the warmer months of spring and summer when humidity levels are higher. In the United States, mold allergies usually start in late spring and can last through the fall. The timing and length of mold allergy season, however, varies depending on geographic location, with regions closer to the equator experiencing a longer season than those farther north. Molds are also more likely to occur in certain regions as a result of certain environmental variables, such as destruction caused by natural disasters like hurricanes or floods.

Understanding Mold Allergy Season
Mold allergy season is a time of year when mold spores are at their highest concentrations in the air, causing an increase in allergic reactions and other health issues. At this time, those with hypersensitivities or asthma may have allergic reactions. To gain greater insight into the causes of mold allergy season and how to guard against its repercussions, it’s important to be aware of peak activity periods and areas where exposure levels are highest.
Mold allergy season occurs during certain times of the year when mold spores are released into the air in large numbers. In response, allergy and asthma sufferers may experience sneezing, coughing, watery eyes, and skin irritation. Molds can also cause serious health problems if left unchecked over time.
Mold allergy season typically begins in late spring/early summer and continues through autumn until winter arrives. This is because warm temperatures create ideal conditions for molds to grow and release their spores into the air–particularly during periods with high humidity levels or after heavy rainfalls that create damp environments. Some states tend to be more affected by seasonal allergies than others due to environmental factors like climate conditions or water damage caused by natural disasters such as hurricanes or floods.
Still, mold is very persistent and can survive during winter months, according to Thermo Fisher Scientific. Although snow cover may lower mold counts, it doesn’t actually kill most species. After a spring thaw, surviving mold will thrive on vegetation killed by winter cold.
What is Mold Allergy Season?
Mold allergy season typically occurs when temperatures and humidity levels are higher, conditions that are conducive to mold. Molds grow by releasing tiny spores into the air, which then can be inhaled or come in contact with skin or eyes. Allergens from the spores emitted by molds may bring about reactions in certain individuals, ranging from sneezing and a runny nose to coughing, congestion, and itchy eyes. Those with asthma and allergies may experience more intense symptoms than normal. In extreme cases, these reactions can even lead to anaphylaxis, which requires immediate medical attention.
When Does Mold Allergy Season Occur?
Mold allergy season typically peaks during the warmer months of spring and summer when humidity levels are higher. In the United States, mold allergies usually start in late March or early April and can last through September or October. The timing of mold allergy season varies depending on geographic location, with regions closer to the equator experiencing a longer season than those farther north.
Humidity is one of the biggest factors contributing to increased indoor mold growth during this time. As air temperatures rise outside, more moisture is added to the air from evaporation, increasing indoor humidity levels. These conditions create an ideal environment for molds and other fungi to grow indoors as they thrive in warm and moist conditions. Additionally, some states may experience heavier rainfall during these months, which also contributes to higher humidity levels indoors that promote mold growth.
Which States Have The Most Issues With Molds?
The top five states affected by molds due to climate conditions are Louisiana, Florida, Mississippi, Alabama, and Georgia. Characterized by higher humidity levels and longer-lasting seasonal allergies due to their warm climates, these states are more prone to mold growth than other states.
Water damage caused by natural disasters like hurricanes or floods is another major contributor to mold problems in certain regions. The states most affected by water damage due to natural disasters like hurricanes and floods are Texas, Louisiana, Florida, North Carolina, and South Carolina. Indeed, these states have all been affected by powerful hurricanes, resulting in water damage and an abundance of mold spores.
Contributing Factors Affecting Your Body’s Reaction Towards Molds
There are several factors that can contribute to an individual’s sensitivity toward molds. These include genetics, environmental exposures, and even lifestyle choices.
Genetics:
Genetics can determine how sensitive an individual is to mold spores and other allergens. People with a family history of allergies or asthma may be more likely to develop allergic reactions when exposed to molds.
Environmental Exposures:
Mold spores can enter the home through open windows, air conditioning systems, ventilation ducts, and other sources of air circulation. If not well maintained, or cleaned regularly, air circulation sources like open windows, ventilation ducts, and air conditioning systems can cause the build-up of mold spores.
Lifestyle Choices:
Certain lifestyle choices such as smoking cigarettes indoors or having furry pets can also increase one’s risk of developing an allergy toward molds. Additionally, people who spend long periods of time outdoors, such as farmers or gardeners, may be more prone to allergies due to their frequent contact with soil that naturally contains mold spores.
Common Symptoms of A Mildew/ Fungal Infection
Mildew and fungus can cause a range of symptoms that are often mistaken for allergies. Runny nose, sneezing, congestion, coughing, and wheezing are all common symptoms associated with exposure to mildew or fungi. In some cases, skin irritation may be experienced when in contact with fungal particles on surfaces like carpets or upholstery. People who suffer from asthma or other respiratory conditions may find their condition is aggravated when exposed to molds or mildews.
Treatments Available For Managing Mildew/Fungal Infections
Mildew and fungal infections can be an uncomfortable, irritating experience. Fortunately, a number of treatments are available to help manage mildew/fungal infection symptoms. Common medications include antihistamines and decongestants to reduce histamine release, and nasal corticosteroids to reduce swelling in the airways. Nasal corticosteroids are another type of medication that can be used to reduce swelling in the airways caused by mold spores or other allergens. This type of medication may be recommended in more serious situations where antihistamines alone do not offer enough relief from symptoms.
Immunotherapy shots may also be recommended for individuals with severe reactions or chronic allergies related to mold exposure. The goal here is to slowly introduce small doses of allergens into the body over time so that it builds up immunity against them over time and reduces allergic reactions when exposed again in the future. With any treatment plan for mildew/fungal infection, it’s important to follow your doctor’s instructions carefully and take all medications as directed for the best results.
How Can Air Purifiers Help With A Mildew/ Fungal Infection?
Air purifiers can be a great help to those suffering from fungal infections, especially during allergy season. Air purifiers with the right filtration systems can aid in reducing exposure to fungal spores and consequently decrease any allergic reactions they may cause.
When it comes to the types of filters required to combat fungi, High Efficiency Particulate Air (HEPA) filters are best suited for this purpose. HEPA filters boast a greater than 99 percent capacity for capturing particles of 0.3 microns or smaller, which makes them adept at eliminating mold spores and other common irritants such as dust mites, pet dander, and pollen. Activated carbon is also beneficial for air purification, as it helps to trap odors created by mold and other airborne contaminants.
Ensure the components of the air filter are regularly maintained and replaced according to manufacturer guidelines. This means regularly replacing the filter cartridges so they don’t become clogged with debris and lose their effectiveness at trapping pollutants out of the air stream. Installing a dehumidifier in conjunction with an air purifier can help reduce the risk of mold growth due to high humidity.
Frequently Asked Questions: What is Mold Allergy Season?
What Triggers Mold Allergies?
Microscopic spores can be released into the air when there is an abundance of moisture, such as in a damp basement or bathroom. They can also enter through open windows and doors from outdoor sources like soil, plants, and decaying organic matter. Allergic reactions to these spores may include sneezing, coughing, congestion, itchy eyes, and throat irritation.
What is a Mold Allergy?
Mold allergies are caused by breathing in airborne particles that come from fungi like molds and mildew. Treatment typically involves avoiding exposure to mold spores, taking antihistamines for symptom relief, and using air purifiers with HEPA filters to remove these allergens from indoor air quality.
How to Tell the Difference Between Mold Allergies and Seasonal Allergies?
Mold and seasonal allergies can be difficult to tell apart, but there are some major distinctions. Mold allergies typically cause symptoms year-round, whereas seasonal allergies tend to only occur during certain times of the year. Moreover, if you have a mold allergy, it can lead to skin irritation or even a rash apart from the usual respiratory signs like sneezing and coughing. Rashes are not typically seen in seasonal allergies. If you’re unsure whether your symptoms are due to mold or seasonal allergies it may be best to consult an allergist for testing and diagnosis.
