A recent study published by the Joint Research Centre (JRC) analysed the interaction between heat and humidity. They found that the combination between the two - and the resulting heatwaves - will leave people exposed to significant health risks, especially in East Asia and America’s East Coast.

Heatwaves amplified by high humidity could reach above 40 degrees Celsius and may occur as often as every 2 years, leading to very serious health risks.

If global warming trends continue, many more people are projected to suffer and even die from sun strokes.
