New research indicates certain countries are experiencing extended periods of heat stress. This phenomenon is not limited to areas that previously struggled with heat stress, as some regions are now feeling its effects for the first time. Some nations are seeing an increase in heat stress duration, with the affected period now lasting one to two months longer than it did in the past.

The study reveals that this trend is affecting various parts of the world. Further information on this topic can be found through KSAT 12, which reported on the study's findings. Details about the research and its implications are available from this source.
