Allergies occur when your immune system overreacts to normally harmless substances called allergens that often don’t cause a reaction in most people. Examples of allergens are mold, dust mites, pollen, bee venom, pet dander, and even food. If allergic, your immune system will produce antibodies to identify that particular allergen as harmful so that when you come in contact with an allergen, your body will trigger a reaction such as inflamed sinuses, airways, skin, or digestive system.

Medical professionals estimate that one-quarter of the population is affected by allergies, with children making up roughly half of allergy sufferers. Remember that allergies can affect people differently, ranging from minor irritations, to chronic suffering, to anaphylaxis, which can be a potentially life-threatening emergency if not treated immediately. Moreover, the substances that trigger your allergies, including hay fever, can also trigger more serious respiratory reactions such as asthma, making it important to take them seriously. Symptoms of allergies can be diverse but often include:

Although most allergies aren’t curable, treatments can help relieve your symptoms. If over-the-counter allergy medication doesn’t work, you should start by trying at home management methods, such as taking showers or eating honey, and then see a doctor for diagnosis and treatment if your symptoms don’t let up.

The Difference Between Allergies and Colds

Differentiating between allergies and colds can be a challenge because they share many of the same symptoms, such as sneezing, coughing, and a runny or stuffy nose. However, when it comes to figuring out if you are experiencing allergies, or the onset of a sickness, you must consider the time of year, symptom duration, and specific symptom characteristics.

Symptom Duration and Onset

The duration and onset of symptoms is our first clue for differentiating between allergies and colds. Cold symptoms typically develop gradually and resolve within a week to ten days. Alternatively, allergy symptoms can persist as long as the individual is exposed to the allergen, which could be for days, weeks, or months during allergy season. Additionally, allergy symptoms appear almost immediately after exposure to the allergen and can last continuously if the allergen remains in the environment.

Specific Symptom Characteristics

Certain symptoms are more suggestive of allergies than colds. For instance, itchy eyes, ears, and throat are common in allergies but rare in colds. Moreover, allergic reactions often cause watery and itchy eyes, which are not typical symptoms of a cold. Conversely, colds may be accompanied by body aches, fever, and sore throat, which are uncommon in allergic reactions. The nasal discharge in allergies is usually clear and thin, whereas in colds, it can become thick and discolored over time. Here are 5 guidelines to help you determine between a cold and allergies:

	Cold	Allergy
Incubation Period	The virus replicates for 1-3 days before symptoms show up. You are contagious during this time, even if you feel fine.	There is no incubation period, as allergies are triggered immediately when exposed to allergens, such as pollen, dust, or pet dander.
Onset of Symptoms	Symptoms like a sore throat, sneezing, runny nose, and slight fatigue typically appear after the incubation period.	Symptoms often start immediately after exposure to allergens, typically sneezing, runny nose, itchy eyes, and congestion without a sore throat or fatigue.
Peak Symptoms	Peak symptoms include congestion, coughing, nasal discharge, and sometimes a low-grade fever. These symptoms worsen over the first 2-3 days.	Allergy symptoms can remain constant, with sneezing, itchy eyes, runny nose, and nasal congestion. There’s usually no fever, and symptoms can last as long as you’re exposed to the allergen.
Symptom Decline	Symptoms gradually improve after a few days, with a thicker nasal discharge and lingering cough. Energy starts to return, and you begin to feel better.	Symptoms persist as long as you are exposed to allergens. When allergens are removed, symptoms may decrease, but they don’t follow the same decline pattern as a cold and won’t improve on their own without treatment.
Recovery	Full recovery typically takes 7-10 days, though a cough may linger. Rest and self-care aid in recovery.	As long as you avoid allergens, symptoms can subside, but they don’t “resolve” in the same way a cold does. Treatment, such as antihistamines, may be needed for longer-lasting relief.

Seasonality

Allergies are usually seasonal and occur at specific times of the year. For instance certain allergens, like pollen from trees, grasses, or weeds, may spread at different points throughout the year, depending on weather and geography. For example, many people experience seasonal allergic rhinitis, also known as hay fever, during spring and fall. On the other hand, colds are more common during the fall and winter as many of us have experienced with flu season. But, they can still occur at any time of the year. Overall, be aware that the frequency of colds increases in colder months while allergies are more tied to the presence of environmental allergens rather than temperature changes. If you see pollen covering your car during late spring or early fall, you may be more accurate in blaming allergies for your symptoms. Alternatively, if your entire family is bedridden for a few days, you might be more correct in assuming you’ve caught a bug.

Other Important Differences

Another factor to consider is if you have a fever; colds can be accompanied by a mild fever, while allergies do not cause fever. Also, allergies can trigger asthma symptoms, such as wheezing or shortness of breath, in susceptible individuals, which is less common with colds.

Overall, while allergies and colds share some overlapping symptoms, paying attention to the time of year, symptom duration and onset, and specific symptoms can help you figure out which is which.

Managing Allergies

Now that you know how to tell the difference between having seasonal allergies or a cold, lets look at how you can manage your symptoms. Neither are pleasant to experience, and there are various methods, from over-the-counter (OTC) medicine, to at-home remedies, to professional medical care, that you can take advantage of to manage your symptoms. Luckily, there is some overlap in the methods used to alleviate both cases, hopefully alleviating any and all of your discomfort if experiencing both at the same time.

When it comes to over-the-counter medicines, antihistamines are the most common and helpful treatment for seasonal allergies as they block histamine, a substance your body makes during an allergic reaction, reducing sneezing, itching, and runny nose. Nasal corticosteroids are another solution effective for reducing inflammation and treating nasal symptoms from allergies. Decongestants can also help with nasal congestion but should be used for only a few days to avoid rebound congestion. Some medicines combine an antihistamine and a decongestant, such as Claritin-D and Allegra-D

For at home remedies, using a saline nasal rinse or neti pot can help clear allergens from your nose, reducing symptoms. In general, keeping your windows closed during high pollen seasons and using air purifiers can also reduce your exposure to those allergens causing your symptoms. Be sure to consider showing regularly and taking off your shoes and clothes when entering your home to reduce its spread around your home. Moreover, avoiding alcohol and caffeine, monitoring local pollen counts, and eating antioxidant-rich foods like fruits and vegetables or even honey can help manage your symptoms.

If OTC medications do not alleviate symptoms, if they are severe, or if you experience asthma symptoms, such as wheezing or difficulty breathing, you should see a doctor. An allergist can give you tests to identify specific allergies and may recommend prescription medications, allergy shots (immunotherapy), or other treatments.

Managing Colds

While there is no cure for the common cold, OTC cold remedies such as decongestants and antihistamines can reduce nasal congestion and runny nose, respectively. Pain relievers like acetaminophen or ibuprofen can alleviate fever, sore throat, and headaches. Be sure to use these medications according to the label instructions to avoid side effects and be aware of giving it to children of those prone to Reyed Syndrome.

For at home remedies, drinking lots of fluids and getting rest are always great for recovery. Warm liquids, such as soup or tea with honey, can soothe a sore throat and relieve congestion. Humidifiers can add moisture to the air and help ease coughs and congestion. Gargling with salt water may also relieve a sore throat.

If cold symptoms persist for more than 10 days, become significantly worse, or are accompanied by a high fever, shortness of breath, or intense headaches, it’s time to see a doctor. These or other symptoms could be signs of a bacterial infection, such as sinusitis or pneumonia, which may require antibiotics.

Avoiding Allergy and Illness Triggers

Avoiding allergy triggers and protecting yourself from catching a serious cold virus or illness can be done by understanding where to find common allergens and cold viruses. Here’s how you can manage both:

Avoiding Allergy Triggers

1. Know Your Triggers: The first step in avoiding allergy triggers is to know what they are. Again, common triggers include pollen, dust mites, mold, pet dander, and certain foods. An allergist can help you identify your specific triggers through skin or blood tests.
2. Limit Outdoor Activities During High Pollen Counts: Know how to read and monitor pollen counts. Pollen counts are typically highest during early morning or on windy days. Keeping track of pollen forecasts through local weather channels or websites and staying indoors during peak times can help reduce your exposure.
3. Use Air Purifiers: An air purifier with a HEPA filter can remove many allergens from the air inside your home, including pet dander, dust mites, and pollen. Be sure to regularly clean your HVAC system too and follow maintenance schedules to reduce the circulation of allergen.
4. Maintain Cleanliness: Regularly wash bedding, curtains, and clothing in hot water to kill dust mites. Use a vacuum again with a HEPA filter to reduce dust and pet dander in your home.
5. Control Humidity: Mold and dust mites thrive in high humidity. Using dehumidifiers to keep indoor humidity below 50% can help control these allergens specifically.

Other simple solutions include lifestyle changes such as wearing a mask while outdoors, avoiding mowing the lawn, showering after being outdoors, changing your diet, and more, can help you live with less symptoms.

Keeping Safe from Colds

1. Practice Good Hygiene: Regularly wash your washing with soap and water every time you get home is one of the easiest ways to protect yourself from cold viruses. Singing happy birthday to yourself twice is a good mental timer! Use alcohol-based hand sanitizers if needed.
2. Buy an Air Purifier: Air purifiers with a HEPA filter can capture 99.97% of particles that are 0.3 microns or larger, including pollen, dust mites, pet dander, and mold spores. For cold viruses, although air purifiers cannot cure a cold, they can help reduce the spread of airborne viruses and maintain a healthier indoor environment. 
3. Avoid Close Contact with Sick Individuals: Cold viruses are spread through droplets when an infected person coughs or sneezes. Keeping a distance from people who are sick and avoiding sharing utensils or personal items should reduce your risk of catching what they have.
4. Strengthen Your Immune System: A healthy diet rich in fruits, vegetables, and whole grains, regular physical activity, adequate sleep, and managing stress can help make your immune system happy and make it more capable of fighting off cold viruses.
5. Use Disposable Items When Sick: If you or someone in your household is sick, using disposable cups and utensils can prevent the spread of the virus to others.
6. Keep Your Surroundings Clean: Regularly disinfecting surfaces like doorknobs, light switches, and countertops can help eliminate cold viruses. Ensure good ventilation in your living and workspace to dilute any airborne viruses.

These are a few of many strategies to boost your health and reduce your exposure to allergens and sicknesses. While it may not be possible to avoid all allergens or eliminate the risk of colds entirely, these solutions can help you manage your symptoms before they begin.

Benefits of Air Purifiers for Allergies and Colds

As mentioned, air purifiers are an excellent approach for managing allergies and cold symptoms. These devices work by circulating air through a series of filters, capturing and removing various airborne particles, allergens, and, in some cases, pathogens. 

For allergy sufferers specifically, air purifiers equipped with High-Efficiency Particulate Air (HEPA) filters are particularly effective. HEPA filters are capable of trapping at least 99.97% of particles as small as 0.3 microns in diameter. This includes the common allergens we’ve mentioned including pollen, which triggers hay fever; dust mites, which are found in bedding, upholstery, and carpets; pet dander, commonly resulting from most animals; and mold spores, being particularly problematic in damp areas. By capturing these particles, air purifiers can significantly reduce the concentration of allergens in indoor air, helping ease symptoms such as sneezing, congestion, and itchy eyes.

For colds, while air purifiers cannot cure them, they can play a role in preventing the spread of cold viruses within indoor spaces. Some air purifiers are equipped with UV-C light technology or include filters treated with antimicrobial agents that can inactivate or kill viruses and bacteria on contact. These technologies add an extra layer of defense by potentially reducing the presence of pathogens in the air. However, be sure to note that not all air purifiers can effectively remove or neutralize viruses, and their performance can vary widely based on the technology used and the specific pathogens in question.

The effectiveness of an air purifier in helping cold and allergy symptoms also depends on using it correctly and maintaining it regularly. Try to place in areas where you spend most of your time, such as bedrooms or living areas. The purifier should be operated continuously to maintain a constant filtration process, as allergens and viruses can quickly accumulate again when it’s turned off. Regular replacement of filters according to the manufacturer’s guidelines is necessary to maintain its lifespan and effectiveness over time.

Along with these factors, be sure to consider the size of the room you place it in, your desired effectiveness and speed, noise levels, time of year, and budget before investing in one for your home. Overall, these tools are a great solution for protecting yourself and family against allergy season and the common cold. 

FAQ

How Do You Stop Body Aches From Allergies? The best way to stop body aches from allergies is to reduce exposure. Use an air purifier to eliminate airborne particles such as dust mites, pollen, and pet dander. Keep windows closed during high-pollen times of day and regularly clean surfaces with a damp cloth or vacuum cleaner. Shower after being outdoors to remove any remaining allergens on your skin or hair.

Can Allergies Make You Cold and Achy? No, allergies do not directly make you cold and achy. Allergies can trigger the release of histamine in the body which may lead to sneezing, runny nose, itchy eyes or throat, and other issues. But these responses may come with a rise in temperature instead of a drop. Being cold and achy is more likely caused by a virus such as influenza or the common cold or allergies

Can Pollen Make Your Whole Body Ache? No, pollen cannot make your whole body ache and mild body aches. Allergies to pollen can cause a variety of symptoms such as itchy eyes, runny nose, and sneezing. These symptoms are typically localized to the upper respiratory tract and do not generally affect other parts of the body. In some instances, allergies may lead to fatigue or headaches; however, these are usually due to lack of rest or other causes rather than the pollen exposure itself.
