Cardiovascular-related deaths due to extreme heat are expected to increase between 2036 and 2065, according to a study modelled in the US.

The researchers, whose work is published in Circulation, predict that adults age 65 and older and people of colour will likely be disproportionately affected. It is because many have underlying medical conditions or face socio-economic barriers that can influence their health -- such as not having air conditioning or living in locations that can absorb and trap heat, known as “heat islands".
