Londoners told to reduce physical activity on Friday due to pollution | London | The Guardian
Government advises older people and those with lung or heart issues to avoid strenuous activity altogether
The government’s forecast predicts pollution levels will hit band 10, the highest level on the scale. The last time pollution levels hit this mark was in March 2018.
Older people and those with lung or heart problems should avoid strenuous physical activity, the government’s official advice stated, while people with asthma may need to use inhalers more often.
Even healthy people should “reduce physical exertion, particularly outdoors, especially if you experience symptoms such as a cough or sore throat”.
