Yes, allergies can cause sweating. While not a hallmark symptom like sneezing or itchy eyes, sweating can be an unexpected reaction to allergens.
Here's why:
- Histamine Release: Allergic reactions involve the release of histamine, a chemical that causes various symptoms, including sweating. This can happen when your body is exposed to an allergen like pollen, dust mites, or certain foods.
- Cholinergic Urticaria: This condition involves hives (raised red bumps) appearing when your body temperature rises and you start to sweat. It's a specific type of allergic reaction triggered by heat.
- Night Sweats: Some allergic children experience intense sweating during the first few hours of sleep, especially at night. This might be related to the release of histamine or other chemicals in response to allergens.
Examples:
- Seasonal allergies: People with hay fever (allergic rhinitis) may experience sweating as an unusual symptom, alongside congestion and other typical allergy symptoms.
- Food allergies: Food intolerance can trigger sweating as a symptom alongside other reactions like nervousness, tremor, and palpitations.
Remember: If you're experiencing excessive sweating along with other allergy symptoms, consult a healthcare professional. They can determine the underlying cause and recommend appropriate treatment.
