1. What can I do to protect myself this season?

- have an asthma action plan (if advised to by your GP) and have practical knowledge of the four steps of asthma first aid
- have reliever medication appropriately available in grass pollen season and be aware of how to use it (ideally with a spacer)
- be alert to and act on the development of asthma symptoms as explained in your asthma action plan if you have one, or if you don’t, use asthma first aid.
