Pollen

Pollen can trigger asthma symptoms in some people. Pollen is a powder-like substance produced by certain types of trees, grasses, weeds and flowers.

• Review your treatment with your doctor or asthma nurse in advance of the hay fever season
• Look out for pollen forecasts on the television, in newspapers or on the internet - if high counts are forecast in your region, try to reduce the time you spend outside
• To help avoid pollen as a trigger for children's asthma, don't stop your child from playing outside, but be aware that a high pollen count could cause problems
