Do you sometimes feel like you just have a cold, your eyes are itchy, your nose is stuffy, and you're sneezing, but you don't really have a fever? You've probably heard of something called 'Cedar Fever.' Is this really a flu? Or is it something else? Let's take a look at this today, because it's important for everyone to be aware of things like this.
What is this "Cedar Fever"?
Simply put, "Cedar Fever" isn't really a fever. It's an allergy . It's a reaction to something that's harmless. In this case, it's pollen from a tree called "Mountain Cedar" (also known as "Juniper").
Imagine, when you walk by these cedar trees, the pollen from those trees gets into your nose and eyes. Then your body's immune system thinks, "Wow, what's gotten into my body? This must be something dangerous!" Then, to fight off this "dangerous invader," your body releases a series of chemicals. Those chemicals are what give you the symptoms you mentioned, like a runny nose, itchy eyes, and stuffy nose. So, even though it's called "cedar fever," most people don't actually get a fever . Sometimes you might feel a little bit of a fever, but it's not a high fever.
Let's learn a little about these cedar trees.
"Mountain Cedar" is a species of tree belonging to the "Juniper" family. These trees are mostly found in states like Texas, Arizona, and New Mexico in the United States. They are also found in countries like Mexico and Japan. This type of tree is not very common in Sri Lanka.
The important thing is that only the male trees of these cedar trees produce pollen . This pollen comes in a small, orange-brown cone. Female juniper trees have a cone that looks like a blueberry. So, you can see that the pollen that causes this allergy comes from the male trees.
When is "cedar fever" most common?
We usually think of allergies as springtime, when the flowers are blooming. But "cedar fever" is a little different. It's most common in the winter , from December to February. Some people can start having symptoms as early as November and continue into March.
This is because juniper trees produce pollen in the winter. Especially in areas like Texas, there is a lot of pollen in the air at this time of year. In fact, sometimes when you look at these juniper trees, it looks like they are smoking! That's how much pollen is released.
Although we in Sri Lanka may not be directly affected by this "cedar fever", it is important to be aware of pollen allergies. Because, in our country too, pollen is released from various trees and plants, and some people can also be allergic to them. Therefore, it is good to be aware of the symptoms and treatment methods of this disease.
What are the symptoms of "cedar fever"?
The symptoms of "cedar fever" are very similar to those of a common cold or flu. That's why many people think it's a cold. Because it occurs during a time when colds and flu are common.
Here are some of the main symptoms:
- Runny nose
- Itchy and watery eyes
- Cough or sore throat
- Sneezing
- Sometimes a low/mild fever
- Partial loss of smell or taste
- Fatigue
Now you understand, it's reasonable to assume that these symptoms are a cold. However, if these symptoms persist for several days, especially if they persist without a fever, it's more likely that it's an allergy.
Important: If you have a respiratory condition like asthma , this "cedar fever" may worsen your symptoms. You may experience difficulty breathing, chest tightness, and wheezing. If this happens, you should definitely seek medical advice.
Why does this "cedar fever" occur? What are the causes?
As we've discussed before, when cedar pollen enters the body, our immune system mistakes the pollen for something dangerous. Then, to fight off the "invader," the body releases chemicals like histamine. Those chemicals are what cause those allergy symptoms.
In fact, experts can't say for sure why some people develop allergies and others don't. But genetics and environment have been found to play a role. This means that if someone in your family has allergies, you're more likely to develop them too.
When the amount of cedar pollen in the air is high, the likelihood of developing "cedar fever" increases. Juniper trees pollinate during cold weather, usually after a cold front. At this time, the weather is dry and the air pressure is changing. This is the best environment for a juniper tree to pollinate. This pollen is collected by strong gusts of wind, creating a kind of pollen storm. "Cedar fever" peaks in mid-January.
Are "Cedar Fever" and "Hay Fever" the same thing?
Hay Fever, or medically known as Allergic Rhinitis, is a collection of symptoms caused by an allergy, including sneezing, nasal congestion, itchy nose, and sore throat. Hay fever symptoms can be triggered by things like pollen, pet dander, and mold.
"Cedar fever" is not the same as "hay fever." However, "cedar fever" can cause symptoms similar to "hay fever." Simply put, "cedar fever" can be a cause of "hay fever."
How do you know for sure if you have "cedar fever"?
If you have these symptoms, a doctor can perform allergy tests to determine if you have a pollen allergy.
- Skin prick test: This is the most common test. This involves placing a very small amount of the suspected allergen on your skin and making a small prick. The skin is then examined to see how it reacts. If it becomes red and swollen, it means you are allergic to that substance.
- Blood test: This can also diagnose allergies.
In addition, your doctor may also make a guess based on things like when your symptoms started and how long they've been present. For example, if you have these symptoms around the same time you're exposed to cedar pollen, and you don't have a fever or other infection, they may think it's a pollen allergy.
What are the treatments for "cedar fever"?
There are several ways to treat "cedar fever." These include over-the-counter (OTC) medications, prescription medications, and lifestyle changes.
Medication Types
Here are some of the most commonly used medications:
- Antihistamines: Examples include Cetirizine (Zyrtec®), Loratadine (Claritin®), and Azelastine (Astelin®). These work by blocking the action of a chemical called histamine in the body that causes allergies. They come in the form of pills, liquids, or nasal sprays.
- Decongestants: These work by constricting the blood vessels in the nose, reducing nasal congestion. Examples: Pseudoephedrine (Sudafed®), Phenylephrine (Sudafed PE®). These are also available as tablets, liquids, or nasal sprays.
- Antihistamine and decongestant medications: For example, `Loratadine/Pseudoephedrine (Claritin-D®)` and `Fexofenadine/Pseudoephedrine (Allegra-D®)`.
- Nasal sprays containing corticosteroids: An example is `Fluticasone (Flonase®).` These reduce swelling inside the nose and relieve congestion.
- Leukotriene inhibitors: An example is ``Montelukast (Singulair®).`` These can only be taken with a doctor's prescription. These pills work by blocking a chemical called leukotriene, which causes swelling during an allergic reaction.
Special medications for those with asthma
If you have asthma, your doctor may prescribe a controller medicine and a quick-relief asthma medicine. These can come as separate medications or as a combination of medications. Inhalers are devices that deliver medicine directly into your lungs. Some people use a different device called a nebulizer to treat asthma.
Allergy Shots - Immunotherapy
This is a long-term treatment. Immunotherapy, or allergy shots, works by changing the way your immune system responds to the allergen (in this case, cedar pollen) over time. This means that your body gradually gets used to cedar pollen, so that it doesn't react as badly to the pollen when it's ingested. Sometimes your doctor may also prescribe a sublingual tablet. But remember, this method takes time to work. So if other medications don't help, don't delay seeing an allergist.
Lifestyle Changes
While it's hard to avoid going outside completely, you can make some changes to your daily routine to reduce your exposure to pollen. For example, try to avoid going outside on dry, windy days, as that's when cedar pollen is at its highest. Other things you can do:
- Keep the doors and windows of your home closed. Keep the windows closed when driving. This will reduce the amount of pollen that gets inside.
- Change and wash your clothes after you come back from outside. It's best to use a dryer to dry your clothes.
- Your pet's fur can accumulate pollen, so you may need to bathe him more often.
- Clean indoor and outdoor surfaces regularly to remove pollen particles.
- Check the pollen levels before going outside. You can find this out on weather websites and apps.
- Wear a dust mask, hat, and sunglasses when you go outside. This will reduce the amount of pollen that gets into your mouth, nose, and eyes.
- Change the AC (Air Conditioner) filter in your car and home.
What is the best thing for "cedar fever"?
Treating allergies is different for everyone. What works for one person may not work for another . While some people find relief with over-the-counter medications, others may need prescription medications or allergy shots. So it's best to talk to your doctor to find the treatment that's right for you.
How long will this "cedar fever" last? When will it get better?
Cedar fever is a seasonal condition. This means that it usually goes away on its own after a while. If you have allergy symptoms during the winter months, but don't have a cold or fever, it could be cedar fever (especially if you live in an area with lots of trees). It doesn't affect you year-round. Symptoms are usually at their worst from December to February. Symptoms should subside in the spring.
Can't "cedar fever" be prevented?
No, we can't completely prevent allergies . We can only manage the symptoms. That means reducing exposure to pollen and treating symptoms when they occur.
How do I take care of myself? / How can we protect ourselves from this situation?
Many people can find relief from the symptoms of "cedar fever" with medications. It may take some time to find the right medication for you. Talk to your doctor to find the best treatment for your symptoms.
Although it may be difficult to stay indoors for weeks or months, the best way to protect yourself from pollen is to try to limit your exposure to it as much as possible.
When should you see a doctor?
If you have symptoms of "cedar fever," see a doctor. Many people find relief with over-the-counter (OTC) allergy medications. However, if these don't help, or if your symptoms are so severe that they interfere with your daily activities , see a doctor for more effective treatment. You don't have to suffer through allergy symptoms - there are treatments that can help.
