Running beneath the shade of trees is not only a refreshing experience, but it also has numerous health benefits. Trees play a vital role in generating clean oxygen and reducing heat in urban areas. In London, scientists have estimated that trees have saved more than 150 lives over eight years by reducing large patches of the city by up to 35°F (2°C). However, developing global cities often prioritize concrete car parks and pedestrianized zones over natural ones, leading to the “Urban Heat Island Effect.”
This effect can cause higher temperatures that exacerbate existing health conditions such as cardiovascular diseases, respiratory problems, and even diabetes. Urban areas also tend to have higher levels of air pollution without trees to provide filtering. A recent study published in IOP Science found that during the heatwave events of 2022, tree coverage helped avoid around 16 heat attributable deaths in London. The study suggests increasing tree canopy coverage as part of broader public health actions to reduce heat-related mortality in the future.
So, next time you lace up your sneakers for a scenic run, take a moment to appreciate the importance of trees in maintaining both physical and mental health.
