Allergic Rhinitis: Battling Red Eyes and Runny Noses

Allergic rhinitis, also called hay fever, is our bodies’ reaction to specific allergens in the air. The most common such allergen is pollen. The major cause of seasonal allergic rhinitis. Almost 8 percent of US adults have experienced allergic rhinitis of varying degrees at least once in their lives and about 10 to 30 percent of the world population suffer the consequences of it too.

When the allergen comes into contact with your body, the immune system becomes sensitive and overreacts to things which other people may never notice. Allergic rhinitis tends to get worse over the years. People, who haven’t suffered from it before, may suddenly start feeling slight symptoms. A year later, the symptoms can come back in full force.

The funny thing about the common name for this condition (hay fever) is that it doesn’t have anything to do with hay or fever. People with allergies rarely suffer from fever. However, the body temperature may rise slightly.

There are two forms of allergic rhinitis:

  • Seasonal – The symptoms of such condition usually occur in the spring, summer, and early fall. The condition is caused by airborne mold spores and also tree, grass and weed pollen.
  • Perennial – The symptoms of this condition pursue the sufferer all year round. The irritants include dust mites, pet hair, dander, cockroaches or mold. In rare cases, food allergies may cause the common symptoms.

Some people with perennial rhinitis experience worsening of the symptoms in the late spring, summer, and early fall as they have both forms of the hay fever.

What are the symptoms of allergic rhinitis?

  • Runny nose
  • Itchy Eyes
  • Itchy skin
  • Sneezing
  • Red and puffy eyes
  • Fatigue
  • Stuffed nose

What can trigger allergic rhinitis?

  • Outdoor allergens (pollen, grass, trees, weeds)
  • Indoor allergens (per hair/dander, dust mites, mold)
  • Irritants (cigarette smoke, perfume, house cleaning solutions)

How can you deal with allergic rhinitis?

It’s important to take preventive measures in order not to suffer from prolonged bouts of hay fever. Doctors recommend keeping windows closed during the high pollen period. It’s also a good idea to wear sunglasses to minimize the amount of pollen coming into contact with your your eyes. Washing hands frequently, especially after coming back home.

All of the above recommendations are important and should be followed. However, whilst these techniques will help alleviate the problems,they won’t drastically reduce the amount of free pollen floating around. One of the quickest and least complicated ways to dramatically reduce pollen particles in your home is to buy an air purifier.

When looking for the best air purifier for allergies in 2020, you need to determine what you are allergic to. Even though, the majority of purifiers deal with numerous allergies, it’s better to know exactly what your enemy is.

2. Affordable Maintenance

Another important point is the purifier maintenance. Even the most effective and expensive air purifier won’t do its job unless it’s maintained well. This is especially important for highly sensitive allergy sufferers. That’s why filters for the air purifier have to be affordable.

3. Suitable Size

The best air purifiers for different types of allergies must be properly sized. Meaning buying an air purifier, which can service 200 square feet and using it in a 300 square foot room will reduce its effect.

Allergies can be caused by much more than just pollen. Other common causes of allergies are mold, pets, dust and chemical smells. In certain cases, it might be best to find an air purifier designed to target your specific allergy. So for example if you’re allergic to mold, then you need to look for the an air purifier equipped to deal with mold.

The best way to reduce the pet allergy is to keep the exposure to a minimum. However, more than 70 % of owners refuse to give their pets up.

Asthma And Air Purifiers: Saving The Day

Asthma is a respiratory disease, which causes breathing difficulties. An asthma attack can occur on a regular basis (two or more times a day) or appear once a week or even a month. The occurrence frequency depends on the condition’s severity and the appearance of triggers.

More than 230 million people in the world suffer from asthma. Many of them are kids and sadly Asthma is still the most common chronic condition affecting children.

Symptoms of Asthma can be treated to help improve the patient’s condition. Unfortunately however, a full recovery is not possible.

While it’s important to consult a doctor about the asthma treatment, people should have a good idea about the symptoms and triggers.

Asthma Symptoms: Hard To Miss

When the airways tighten and fill with mucus, asthma sufferers can experience the following symptoms:

  • Wheezing
  • Chest pains
  • Tightening of the chest
  • Pressure in the chest
  • Inability to move fast

Quick help during an asthma attack can prevent lethal consequences.

An asthma attack doesn’t come suddenly. In the majority of cases, a person can catch the warning signs of the incoming attack. The signs may come several hours before the attack. They aren’t severe enough to interfere with regular activities:

  • Frequent cough
  • Tiredness and weakness during exercises
  • Shortness of breath
  • Coughing and wheezing after physical activities
  • Signs of allergies (runny nose, cough, stuffed nose, sore throat, headaches)
  • Sleeping problems

Asthma Triggers: What To Avoid

People can go on for days without experiencing an asthma attack. As soon as they face a trigger, it may start in full force.

  • Cigarette smoke – Asthmatic lungs are highly sensitive to smoke. You don’t even have to smoke yourself. Second-hand smoke can do the trick as well.
  • Allergens– Many asthma attacks are triggered by allergens such as dust mites, mold, pollen, and pet dander.
  • Exercise – Physical activities sometimes trigger asthma. However, it doesn’t mean a person should stop exercising since its benefits are numerous. The asthma symptoms during exercise can be managed.
  • Irritating substances in the air – When a person faces such substances as bushfire smoke, wood dust, chemicals, and metal salts, the asthma attack is possible.
  • Stress – Crying and worrying can trigger an asthma attack
  • Medications – Certain meds, such as aspirin can provoke an attack.

As we can see, the majority of asthma triggers have to do with the air we breathe. That’s why one of the ways to ease the symptoms and prevent an asthma attack is buying an air purifier.

Fighting Asthma: What Is The Best Air Purifier For Asthma And Allergies?

The best air purifier for asthma and allergies isn’t hard to find. Such air purifiers should focus on taking all the possible contaminants and allergens out of the air we breathe.

HEPA Filter – HEPA air purifier for allergies and asthma is a must-have for anyone suffering from attacks. The high-quality HEPA filter can take the majority of asthma triggers out of the air. An asthma sufferer should look for trueHEPA or ultraHEPA filter. These filters deal with as many contaminants as possible.

Right Sizing – As in the case of allergies, the air purifier you purchase must fit the room you will use it in. Meaning, if the manufacturer states that the purifier can service a room of 400 square feet, using it in a larger room doesn’t make sense.

Individual Purifiers – Asthma sufferers may benefit from the individual air purifiers, which they can take to the office or a friend’s house. Portable purifiers are good as well since you can use them in different rooms of the house.

Carbon Filter – Since one of the Asthma triggers is cigarette smoke, it’s important to deal with the odor. A carbon filter removes cigarette, household, and pet odors. It’s important to replace this filter on a regular basis. Otherwise, it may become useless.

Air purifiers do a great job dealing with allergens flying through the air. However, they may not protect an asthma sufferer from small particles, which appear due to local disturbances. For example, when your body strikes a pillow or a mattress, the small dust mites, which fly out of it, can’t be dealt with. That’s why it’s important to follow the doctor’s recommendations and always be ready to neutralize the attack.

Final Thoughts

Air purifiers are an excellent choice for people suffering from allergies or asthma. They can keep the air clean thus improving the person’s condition and keeping the symptoms at bay. Choosing the right air purifier for allergies and asthma can substantially enhance the person’s quality of life.
