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 poor air quality is the result of an intense area of high pressure covering western Europe. The associated lack of air movement means emissions from vehicles and other pollutants are not blown away as they usually would be.
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”.
