- Greek police say they believe Mosley died around 4pm local time on Wednesday, just hours after he had set off on a walk.
- Greek police said Mosley is believed to have died of heat exhaustion after losing consciousness while walking in 40°C temperatures.
- This tragedy serves as a timely reminder of the dangers of extreme heat.
When do hot conditions become dangerous?
- Physical activity levels and conditions in the environment significantly affect our risk of developing heat-related illness.
- However, in humid conditions, the sweat on our skin evaporates less readily, as the air already contains plenty of moisture.
- Hot temperatures, sun exposure, humidity and physical activity can all present challenges for the human body.
How is heat exhaustion different from heat stroke?
- Heat exhaustion and heat stroke form part of the continuum of heat-related illness.
- When heat exhaustion is left untreated it can progress to heat stroke.
Who is most vulnerable?
- A combination of both can compound the risk.
- Someone may also be more vulnerable because heat worsens their underlying health issues, such as heart disease.
- People who are unable to respond behaviourally to heat are also at a greater risk.
Underestimating the risks of extreme heat
- Early action is especially important given the symptoms of heat stroke involve confusion and disorientation, which can impair decision-making.
- A person who is affected by heat stroke may not be well placed to adapt their behaviour, such as by seeking shade.
