Environmental Allergies: What Causes Them And How To Prevent Them

environmental allergies

Your immune system causes allergies overreacting to something you might expose to. Allergic reactions can happen when your immune system reacts strongly to a particular allergen, such as pollen or dust mites. These reactions can cause symptoms like swelling, itchiness, and breathing difficulties. It’s not always easy for doctors to identify the exact cause of an allergic reaction because there may not be any specific triggers that set it off. That means people with environmental allergies should take precautions against these allergens wherever possible in order to prevent symptoms from developing.

In this article, we’ll look at some of the most common environmental allergens and how they affect our bodies, as well as how we can prevent reactions from occurring.

What are environmental allergies?

Environmental allergies happen when your immune system reacts to a particular substance, such as pollen or dust mites, which you may expose to regularly. I know these substances as allergens.In some cases, these allergens can actually cause symptoms on their own whereas in other cases they can make existing conditions worse. For example, if you already have hay fever the allergens in pollen will trigger your symptoms. This means that people with environmental allergies are often advised to reduce their exposure to these allergens in order to prevent uncomfortable or even dangerous reactions from occurring.

Symptoms Of Environmental Allergies

Symptoms of environmental allergies can range from mild to severe depending on the person affected. The most common symptoms include:

  • Itching of the skin, eyes, nose, mouth, throat, and/or respiratory system
  • Redness of the skin
  • Wheezing
  • Nausea or vomiting
  • Rapid heartbeat
  • Exhaustion or drowsiness after exposure to an allergen
  • Coughing up thick mucus that may contain blood.

Possible complications for some people are asthma attacks, upper respiratory infections, sinusitis, and bronchitis. Asthma attacks can be fatal if not treated quickly with inhalers and other treatments. Some individuals with environmental allergies might also pursue desensitization therapy, also known as immunotherapy. This is a treatment that’s administered during allergy shots to reduce the body’s reaction to allergens.

Allergies happen when your immune system overreacts to a substance it perceives as dangerous. This means that almost any substance can be an allergen if you have an allergy to it, but there are some substances that are more common allergens than others. Genetics can cause some environmental allergies. Meaning people with particular genes might be more likely to develop allergies to certain substances. I think other environmental allergies happen because of other conditions, such as asthma or the common cold. The presence of these illnesses means you’re more likely to expose to allergens and therefore more at risk of developing an allergy to them.

Can children have environmental allergies?

Yes, it’s very common for children to develop environmental allergies because their immune systems are still developing and not yet able to cope with allergens. Allergies can sometimes appear suddenly in adults but usually. They’ve been building up over months or even years be fore symptoms develop. However, with children, it can be harder to tell where allergies might come from because they’re not yet exposed to too many of the common allergens which adults are more likely to encounter in their daily lives. This means that environmental allergies in young children can sometimes be difficult for parents to identify and prevent.


Most Common Environmental Allergens

There are many substances that can lead to environmental allergies and these allergens can cause a wide range of symptoms. Sometimes, even the slightest exposure to an allergen is enough to trigger a reaction. But usually, your body becomes more sensitive over time so that it takes less and less exposure before you feel ill. Sometimes, reactions are more severe the first time you come into contact with an allergen, but they get less severe each time after. This means that even if you’ve never had symptoms before. It’s important to be aware of common environmental allergens and take steps to reduce your exposure to them year-round.

• pollen – this comes from trees, grasses, and weeds and causes hay fever which includes sneezing, a runny nose, and itchy eyes.

• Dust mites – these microscopic bugs live in pillows, mattresses, and soft furnishings around the home. Their droppings cause asthma-like symptoms such as wheezing and coughing.

• Mold – exposure to mold spores can cause asthma and other breathing difficulties.

There are many things you can do to prevent the symptoms environmental allergens trigger from occurring. If you’re exposed to them. Some steps you can take yourself, such as keeping your home clean and dust-free or wearing sunglasses outside. Which will keep pollen out of your eyes. Other steps might need the help of an expert. Such as an allergist who can advise you on what treatment to take in order to reduce your exposure to these substances.

An allergist is a doctor who specializes in diagnosing and treating allergies. This means he’ll be able to look at your medical history (including any allergies or sensitivities your family might have) and perform allergy tests. This will allow him to work out which substances you’re most sensitive to. So that he can suggest ways to avoid them. For example, an allergist may recommend taking medicine in advance. If you know there’s a particular pollen count in the air at certain times of the year which triggers your symptoms. He may also prescribe nasal sprays or eye drops which you can use when you know there’s a high pollen count in order to protect your airways and eyes from irritation. Alternatively, he might suggest allergy shots which over time reduce the immune system’s sensitivity to allergens so that they don’t trigger reactions anymore.
