Allergy season is in full swing, and you’ve been sneezing nonstop and having itchy eyes. But lately, you’ve also been feeling a bit warm. Could it be a fever? More importantly, can allergies cause a fever?

Allergies are your immune system’s response to substances like pollen, pet dander, dust mites, or mold. These come with many annoying symptoms, and many people wonder whether fever is on that list.

At Healwell Primary Care, we specialize in providing medically grounded advice to answer common health questions. This comprehensive guide will explore the relationship between allergies and fever, when a fever might indicate a more serious condition, and what steps you can take if you’re feeling unwell.

The Short Answer: Allergies Usually Don’t Cause Fever; Why?

In most cases, allergies do not cause fever. Allergies are triggered by your immune system when it overreacts to allergens by releasing chemicals such as histamine. Such a response leads to excessive sensitivity in the eyes, nose, and airways, leading to tenderness, swelling, and burning sensations. However, it does not increase your body temperature. Even if you feel foggy and run down during the allergy season, that does not mean your temperature has reached the fever category. Medically, a fever is typically defined as a body temperature of 100.4°F (38°C) or higher, and it is not a part of the standard allergic reaction.

Common Symptoms of Allergies

Understanding the symptoms of allergies can help you distinguish between fever-related issues and allergies. Hay fever, or allergic rhinitis, typically follows a consistent pattern of symptoms, without an actual fever. Hay fever is a seasonal allergy that usually happens during spring and summer. Understanding these symptoms can help you take a more proactive approach to managing your health.

  • Skin rashes or hives
  • Sneezing and nasal congestion
  • Fatigue is due to poor sleep cycle, chronic inflammation, and an elevated temperature
  • Watery eyes, itchiness, and a sore throat
  • Warm or flushed skin
  • Feeling more tired or lethargic
  • Headaches
  • Scratchy throat

If you are experiencing these symptoms without a thermometer reading of more than 100.4 °F or higher, then you are likely experiencing an allergic reaction, not a fever.

Why do people confuse fever with allergies?

Different factors contribute to misconceptions about allergies causing fever. You can better interpret your symptoms and take appropriate action by fully understanding both conditions.

  • The term hay fever is often misunderstood and suggests the presence of a fever when it is not an actual symptom.
  • Environmental factors, such as warm weather, rigorous outside activities, and indoor heating, can increase body temperature.
  • Fatigue can mimic feverish symptoms.

Understanding these factors can help you make informed decisions when identifying and treating symptoms like fever or allergies.

When to seek medical attention at Healwell Primary Care

While most allergies can be managed with over-the-counter treatments, certain signs need medical attention.

  • If you have a fever of more than 104.5𝆩F for more than 48 to 72 hours
  • You have shortness of breath, chest pain, or a severe headache
  • High-risk patients, such as those with asthma or chronic lung disease
  • Unresponsive to allergy medications

At Healwell Primary Care, we offer comprehensive solutions, such as imaging, rapid patch and skin testing, allergy testing, and personalized treatment plans.

Self-Assessment- How can you keep track of your allergies?

Keeping and maintaining a diary log can help differentiate allergic flares from infection and fever. Constant tracking can help you spot red flags and patterns easily.

  • Trigger notes: note pet exposures, pollen counts, or new foods and medications.
  • Daily logs: routinely record temperature, itchiness, sneezing, general well-being, and mucus color.
  • Symptom scoring: Keep a scale of 0-3 for each symptom category, ranging from none to severe.

Tracking your symptoms allows you to assess when to manage them at home and when to seek medical assistance.

Allergy Prevention Strategies from Healwell Primary Care

Effective symptom prevention can prevent allergies and secondary infections. Structured medication, avoidance, and immunotherapy have all proven to lessen the severity of allergies.

  • Immunotherapy- you can take sublingual drops and allergy shots for long-term relief.
  • Environmental control- frequent bedding washes, HEPA filters, and pollen-avoidance measures.
  • Lifestyle management- take timely rest, adequate hydration, and minimal nasal irrigation to maintain sinus health.
  • Medications- second-generation antihistamines, intranasal corticosteroids, and leukotriene inhibitors.

By implementing these strategic interventions, you can reduce allergic flares.
