Quick read
Key points
- 1
Hay fever (seasonal allergic rhinitis) is an allergic reaction to pollen, causing sneezing, an itchy or runny nose, congestion, and itchy, watery eyes. Symptoms typically follow a seasonal pattern, worsening during specific pollen seasons — tree pollen in spring, grass pollen in early summer, and weed pollen in late summer.

What is Hay Fever?
Hay fever (seasonal allergic rhinitis) is an allergic reaction to pollen, causing sneezing, an itchy or runny nose, congestion, and itchy, watery eyes. Symptoms typically follow a seasonal pattern, worsening during specific pollen seasons — tree pollen in spring, grass pollen in early summer, and weed pollen in late summer.
While not dangerous, hay fever can significantly affect quality of life and sleep during peak pollen season. It's usually well managed with a combination of reducing pollen exposure and appropriate medication.

Clinical context
Starting treatment before your season begins works better
For hay fever, starting antihistamines or nasal sprays a week or two before your usual symptom season begins tends to control symptoms more effectively than waiting until they're already severe.

- 2Symptoms are significantly affecting your sleep or daily life
- 3You develop symptoms of a sinus infection, such as facial pain or thick discharge

Practical steps
Combining an Antihistamine with a Nasal Spray Often Works Best
A combination of an antihistamine and a nasal corticosteroid spray, used correctly and consistently, often controls hay fever symptoms better than either used alone.
- 1Check pollen forecasts and plan accordingly.Staying indoors during high pollen counts, especially in the early morning and evening, can help.
- 2Keep windows closed during high pollen periods.This reduces the amount of pollen entering your home.
- 3Try a non-drowsy antihistamine.These are widely available and can be taken regularly during your symptom season.
- 4Use a nasal corticosteroid spray consistently.These are very effective for congestion but work best used regularly, not just when symptoms flare.
- 5Shower and change clothes after being outdoors.This removes pollen that can otherwise continue triggering symptoms indoors.
