Wildfire smoke can affect our health, usually temporarily, by causing coughing, shortness of breath and irritation to the eyes, nose and throat.
For most people, symptoms improve quickly after moving indoors and away from the smoke.
However, young children, older people and those living with an existing lung or heart condition may be more vulnerable.
People in one of these higher risk groups should try to stay indoors with windows and doors closed and should avoid outdoor exercise. Institutions should set air-conditioning systems to recirculate.
If you are living with a lung condition such as asthma or COPD, carry on following your action plan, keep any medications or inhalers on hand and remember to use your preventer inhaler daily as prescribed.
Anyone who experiences difficulty breathing should seek advice from NHS 111, their GP or, in cases of severe breathing difficulties, the emergency department.
