Allergy - What Causes Mold Allergy and Asthma Symptoms?

Among the most common types of allergies is mold allergy, because mold can develop just about anywhere and can happen at any time of the year. We more popularly know and identify mold as that yellowish or greenish substance that results from our failure to throw out organic materials and clean out dark and damp spaces.

There are two plant groups in the family of fungi: molds and yeast, each of which has around a thousand permutations and versions to its name. While yeasts are characterized by single cells, molds are comprised of multiple cells that branch out when they grow. Both fungi subfamilies are allergic offenders, but only about a few mold species trigger allergic reactions in people.

Molds, when they multiply, also produce millions of spores. These spores are what cause allergies. When inhaled, these microscopic spores give birth to allergic rhinitis. And because they are so tiny and microscopic, escaping exposure to mold spores and susceptibility to mold allergy may be difficult to accomplish. Mold spores can easily bypass our bodies protective functions and lodge themselves into our respiratory organs.

Some people experience a more severe mold allergy attack when they take in food that has been processed with fungi, like cheese. There are also instances when dried food and some mushrooms, as well as yeast-related foods, like vinegar and soy sauce, help worsen the attack. We cannot say exactly the same for penicillin, however, though it is made from the mold Penicillium, because studies have not shown any blatant relationship between it and mold allergy.

Mold allergy or asthma symptoms related to molds can also come with the season, usually from spring to just before fall ends. Mold season is usually at its highest during the summer, because of the moisture and heat. Some molds thrive in cold temperatures, but most of them simply remain dormant until they are unfrozen and given the chance to grow again. Molds are particularly present just after the spring thaw because they feed on dead vegetation that that have been hit by the winter season.

Wherever there is moisture, you can be sure that molds will be there to grow. The best places they can thrive are damp closets and basements, unmonitored refrigerators, bathrooms, air conditioners, mattresses, house plants and uncleaned garbage pails, among others.

Given this information, households should make sure that all spaces are ventilated well and mold-attractive objects aired out regularly to avoid the development of molds.

The most common molds found in the United States are Cladosporium and Alternaria. Actually, there are many other mold species that they usually outnumber the pollen that spreads in the air. Worse than pollen, they can thrive both indoors and outdoors, and can be very tricky to detect at their early development stages. Most people recognize the presence of mold only after they have grown to annoying and smelly levels.

Continuous exposure to mold will not just bring about mold allergy but also lead to lung disease or asthma. If you have started to feel weird coughing symptoms and some wheezing, better have yourself checked immediately to nip the problem at the bud. Your physician will likely have you undergo a series of tests, including X-rays and blood sampling, to determine the cause. Needless to say, mold allergy, while seemingly temporary, is still not something that you should take for granted.

Allergy - Winter Sniffles: Allergies, or the Common Cold?

The cold days of winter bring most of us indoors for the year - and then the sniffles start up. Symptoms like sneezing, congestion, and sore throat are common during the winter months. These unpleasant symptoms can be evidence of a winter cold, but they can also mean indoor allergies. What are the causes of these winter ailments, and how can they be identified (and treated)?

Winter weather can indirectly cause both colds and indoor allergies. Colds increase in winter because people spend more time inside, confined to small spaces where viruses and germs can be easily passed around. Also, the viruses which cause colds thrive in low-humidity environments, which are typically found in the cold dry months of winter. Low humidity, combined with air blowing from indoor heating systems, causes drying of the nasal passages, which can increase susceptibility to infection.

With indoor allergies, it's a similar story. Indoor allergies are caused by dust, which contains a wide variety of allergy-causing particles like animal dander, mold spores, pollen, dust mites and dust mite waste. Spending more time indoors means increased exposure to these allergens. Plus, indoor heating systems circulate air through the house, knocking loose many allergy causing particles on carpets, furniture, and dusty shelves. Then, these allergens are circulated through your home, right along with the warm cozy air.

Colds and allergies also show themselves in very similar ways, making it difficult to tell them apart. Symptoms of colds include congestion, stuffy nose, swelling of sinuses, sneezing, scratchy sore throat, headaches, aches and pains, fever, and a cough. Allergy symptoms include stuffed or runny nose, sneezing, wheezing, sore throat, watery and itchy eyes, and sometimes headaches. The main difference between cold and allergy symptoms is that colds usually come with body aches and pains and possibly a low-grade fever, while allergies do not. In addition, colds usually last 7-10 days, while allergies will persist as long as the exposure to the offending allergen continues. If you have cold-like symptoms which persist for more than two weeks, it's a good guess that you're dealing with an allergy, not a cold.

Complicating matters, frequent colds may in fact result from allergies. Your body responds to tiny allergens by producing mucus, in an attempt to expel them. However, nasal mucus is also a breeding ground for viruses and bacteria, which can cause colds and sinus infections. Treating allergies will help prevent these, which is why it's a good idea to identify allergies early and treat them accordingly.

It's important to distinguish between colds and allergies, in order to give appropriate treatment. Cold viruses thrive in low humidity, and nasal dryness can lead to increased susceptibility to colds, so running a humidifier in cold dry winter months may be helpful. However, dust mites thrive on high humidity, so if you're suffering from indoor allergies, the low humidity is your ally. And while rest and plenty of fluids may cure a cold, allergies will persist as long as exposure continues.

To treat and prevent indoor allergies:

  • Visit an allergy doctor who can help you identify the offending indoor allergens
  • Maintain low indoor humidity to kill dust mites and mold
  • Vacuum using a HEPA filtered vacuum and run a HEPA air purifier to remove airborne allergens
  • Encase mattress, pillows, and bedding in allergen-barrier encasings to protect from dust mite allergies
  • Dust and clean frequently

To treat and prevent winter colds:

  • Wash your hands frequently and disinfect surfaces
  • Get plenty of exercise and rest
  • Eat nutritiously, with lots of fruits and vegetables
  • Avoid alcohol, tobacco, and excess stress
  • Relieve cold symptoms with nasal decongestants and cough suppressants

When treating a cold, remember that medicines may relieve symptoms, but they will not cure the cold. Only giving your body the proper care it needs - rest, proper nutrition, and plenty of fluids - will cure the cold. And with allergies, the best way to treat allergy symptoms is to remove the offending allergens from the environment.
