What Is Grass Pollen?

Grass pollen is a fine powder produced by grass for the purpose of fertilization. This powder is carried through the air during pollen season. For someone with a grass pollen allergy, this may lead to an allergic reaction when breathed in.

Grass pollen allergies occur when the body's immune system recognizes grass pollen as a dangerous intruder. Much like having your body fight off harmful viruses and bacteria, your immune system is triggered into producing a chemical called histamine, to combat these particles. ^2,3

How to Alleviate Grass Pollen Allergy Symptoms

Grass allergy symptoms can be annoying even when they are mild. At their worst, grass pollen allergies can become disruptive, making it difficult for you to enjoy your daily routine. But as with most allergies, there are steps you can take to reduce the impact of grass pollen symptoms.

Watch the pollen count

Start your day right by planning for it. Knowing the daily pollen count can help you estimate how much pollen is in the air. When pollen counts are high, try to limit your exposure to grass pollen as much as possible. You can always use the Reactine® pollen forecast tool found on the left side of the homepage, or learn how pollen count is calculated here.

Take antihistamines

Shower after you have been exposed

Stepped outside for a bit? Gone for a hike? If you have been exposed to grass pollen while you were out, take a shower as soon as possible to wash off the pollen and to avoid bringing those pesky, clingy allergens into your home. This will help minimize your symptoms and prevent allergens from spreading.

Mow away your lawn allergies

You need to know where your grass allergies are hiding, so it’s a good idea to keep your grass short. If you suffer from grass pollen allergy, consider asking a family member for help. If you must mow the lawn yourself, be sure to wear protective gears such as goggles, a mask, and gloves. Remember to take a shower or wash your hands after. ⁵

If you are still unsure of your symptoms or how to alleviate your grass pollen allergy symptoms, consult your doctor or local healthcare practitioner. Be sure to seek professional guidance if taking OTC medications for prolonged periods of time. You should always follow the dosage as indicated on the product label.
