Economic costs resulting from heat stress could reach $1.64 billion in 2035, with a 14% decrease in productivity. Decline in productivity is expected to mainly affect four sectors: construction, services, manufacturing and agriculture.

Losses will be particularly high for workers exposed to adverse environmental conditions, such as those who work in the sun or are subject to other sources of heat, like machinery. The study was conducted by the Yong Loo Lin School of Medicine in Singapore, and was published in the journal Climate.
