Allergies are the body's over‑reactive response to harmless stuff like pollen, pet dander, or certain foods. When you notice sneezing, itchy eyes, or a rash after being near a trigger, it's a sign your immune system is sounding the alarm. This page gives you the basics you need right now and points you to detailed articles that go deeper.
Most people react to just a few common allergens: seasonal pollen, dust mites, mold spores, animal dander, and a handful of foods such as peanuts, shellfish, and dairy. The reaction starts when the body produces IgE antibodies that latch onto mast cells. When the allergen shows up again, those cells release histamine, causing the classic symptoms – runny nose, watery eyes, itchy skin, or even trouble breathing.
Knowing your own triggers is the first step to control. Keep a simple diary for a week: note where you were, what you ate, and any symptoms that appear. Patterns pop up quickly, and you’ll see whether it’s a plant pollen season or a certain cleaning product that’s the culprit.
For mild symptoms, over‑the‑counter antihistamines like cetirizine or loratadine often do the trick. They block histamine and calm the itching and sneezing. If you need longer‑lasting relief, a daily nasal steroid spray can reduce inflammation inside your nose and prevent flare‑ups.
When symptoms get severe – especially if you have trouble breathing – a prescribed inhaler or short‑acting bronchodilator may be needed. Always have an emergency plan if you’re at risk of anaphylaxis: carry an epinephrine auto‑injector and know when to call emergency services.
Lifestyle tweaks can make a big difference too. Use HEPA filters to capture airborne allergens, wash bedding in hot water weekly, and keep windows closed during high pollen days. For food allergies, reading labels carefully and communicating with restaurants can prevent accidental exposure.
If you want a longer‑term solution, talk to a doctor about allergy testing and immunotherapy. Shots or sublingual tablets expose you to tiny amounts of the allergen over time, training your immune system to tolerate it.
