You can’t avoid pollen completely, but you can cut how much reaches your nose and eyes. Mayo Clinic says that limiting exposure reduces symptoms, and the most useful steps are simple: keep windows closed, run the air conditioning, check pollen counts, and wash pollen off when you come inside.
This guide gathers the advice of Mayo Clinic and the major U.S. allergy organizations into one checklist, then covers medicines and longer-term treatment for when avoidance isn’t enough. For more, see our seasonal and pollen allergy guides.

Quick answer: the 8 steps that matter most
- Check daily pollen counts and plan around high days.
- Keep windows and doors closed at home and in the car during pollen season.
- Use air conditioning and a good filter in your home system.
- Avoid outdoor activities in the early morning, and on dry, windy days.
- Don’t mow, rake or garden without a mask, or let someone else do it.
- Shower, wash your hair and change clothes after time outdoors.
- Dry laundry indoors, not on a clothesline.
- Start your allergy medicine before the season begins.
Know your pollen and check the counts
The American Academy of Allergy, Asthma and Immunology (AAAAI) advises monitoring pollen counts so you can limit your exposure on high days. A pollen count is the number of pollen grains in a cubic meter of air, measured by a rooftop instrument over 24 hours and reported for trees, grasses, weeds and mold. Forecasts, by contrast, are predictions based on the previous year’s counts and current weather. AAAAI’s National Allergy Bureau publishes counts from its counting stations.
It also helps to know which pollen bothers you. The American College of Allergy, Asthma and Immunology (ACAAI) lists the typical seasons:
| Pollen | Typical season | Notes |
|---|---|---|
| Trees | Late winter into spring or early summer | Birch pollen can also make some raw fruits itch your mouth |
| Grasses | Spring and early summer | Linked to thunderstorm asthma in some places |
| Weeds, including ragweed | Late summer into autumn | Ragweed blooms August into November and peaks in mid-September; levels peak in the morning |
An allergist can test which pollens you react to, so you know which season to prepare for.
At home
These steps come from Mayo Clinic and ACAAI:
- Close doors and windows during pollen season, at home and in the car (Mayo Clinic, ACAAI).
- Use air conditioning in your house and car (Mayo Clinic).
- Use an allergy-grade filter in your home heating and cooling system and change it regularly (Mayo Clinic).
- Run a HEPA air cleaner in your bedroom and other rooms where you spend a lot of time (Mayo Clinic). Avoid ionizers that make ozone; see do ionic air purifiers work?
- Dry laundry indoors. Pollen can stick to sheets and towels hung outside (Mayo Clinic).
- Wash your hair at night so pollen doesn’t end up in your bedding (ACAAI).
Outdoors
- Time your activities. Mayo Clinic advises skipping outdoor activities in the early morning, when pollen counts are highest, and on high-count days.
- Stay in on dry, windy days (Mayo Clinic). ACAAI notes that rain showers temporarily clear pollen from the air, so after rain can be a better time to go out.
- Delegate yard work. Mayo Clinic says not to mow the lawn or rake leaves. If you have to, ACAAI recommends a NIOSH-rated 95 filter mask and taking your allergy medicine beforehand. See do masks help with pollen?
- Protect your eyes. Glasses or sunglasses limit pollen getting into your eyes (Mayo Clinic).
- Exercise smart. If you run or cycle outdoors, read our guide to running with pollen allergies.
After you come inside
- Shower, wash your hair and change clothes after working or playing outdoors (ACAAI).
- Rinse your nose with salt water. The National Center for Complementary and Integrative Health says there is some good evidence that saline nasal rinses help seasonal allergy symptoms. Use distilled, sterile, or boiled and cooled water. See our neti pot guide.
- Wash your hands after petting an animal that has been outside (ACAAI).
When avoidance isn’t enough
Avoidance lowers your exposure, but many people with pollen allergy also need medicine during the season.
- Start early. AAAAI says hay fever medicines work best when you begin them before you first encounter spring allergens, which can prevent or reduce symptoms.
- Common options include antihistamines and steroid nose sprays. Ask a pharmacist which suits you, especially before combining products; our Claritin-D and Theraflu guide explains decongestants.
- Allergy shots or tablets can retrain your immune system over years. ACAAI says FDA-approved tablets exist for ragweed, northern pasture grasses such as timothy, and dust mites; grass and ragweed tablets are typically taken before and during the season, and treatment may be needed for three years or longer. Your allergist will also prescribe an epinephrine auto-injector in case of a severe reaction. Read allergy drops vs shots.
See an allergist if your symptoms are hard to control, last for months, or come with wheezing or asthma.

Frequently asked questions
How can I avoid pollen allergy?
Keep windows closed and use air conditioning, check pollen counts, avoid early-morning and windy-day outings, let someone else mow, and shower and change clothes after being outside. Starting allergy medicine before the season also helps.
What time of day is pollen highest?
Mayo Clinic says pollen counts are highest in the early morning, and ACAAI says ragweed levels peak in the morning during ragweed season. Weather matters too: dry, windy days are worse, and rain temporarily clears pollen.
Does an air purifier help with pollen?
A HEPA air cleaner in your bedroom and main rooms can help, along with an allergy-grade filter in your heating and cooling system, according to Mayo Clinic. Keep windows closed so you aren’t filtering a constant stream of outdoor air.
Should I shower after being outside during allergy season?
Yes. ACAAI recommends showering, washing your hair and changing clothes after time outdoors, and washing your hair at night to keep pollen out of your bed.
When should I start allergy medicine?
Before the season starts. AAAAI says hay fever medicines work best when begun before you first encounter spring allergens.
Can you cure pollen allergy?
There is no quick cure, but allergy shots or under-the-tongue tablets can reduce your sensitivity over several years. Ask an allergist whether you’re a candidate.
