Understanding Seasonal Allergies

Seasonal allergies, often called hay fever or allergic rhinitis, occur when the immune system reacts to airborne particles such as pollen, dust and mould.

Typical symptoms

Sneezing, a runny or blocked nose, itchy eyes and throat, and sometimes cough or wheeze. Symptoms that peak at particular times of year suggest a seasonal trigger.

Reducing exposure

• Keep windows closed during high-pollen or dusty periods
• Wash bedding regularly in hot water
• Shower and change clothes after being outdoors
• Use a clean, damp cloth for dusting rather than a dry one

When to see a doctor

See a doctor if symptoms disrupt sleep or daily life, if you have wheeze or breathlessness, or if over-the-counter measures are not helping. Seek emergency help for swelling of the lips or throat or difficulty breathing.
