It is essential for human survival to stop global warming.
The book “Deadly Heat” explains why we can only live in a certain area.

This doesn't change anything for you.
We humans can only live in a certain temperature range.
Whether it is too low or too high, there is only a very thin line between what is considered “healthy” for the organism.
Due to global warming, this area is becoming smaller and smaller.
Because even a small increase, like in the book “3 degrees more” by Klaus Wiegandt, throws everything out of balance.
Hanns-Christian Gunga explains what the heat does to us in “Deadly Heat”.

Hanns-Christian Gunga “Deadly Heat”: That’s what the book is about
For us humans, the ambient temperature is very important.
If this increases only minimally beyond the comfortable range, this can lead to heat stroke, with fatal consequences.
The colleagues from 24vita.de explain the difference between sunstroke and heatstroke.
Even if the current temperatures are expected to drop shortly, they are not just heating up in the Mediterranean region.
Up to 45 degrees Celsius were measured here.
In the shadows, mind you.
These temperatures are anything but healthy for the human organism.
Climate change is here and with it unbearably hot temperatures.
Most people are hardly aware that our bodies only function optimally in a very narrow temperature range of 37 °C.
Even with an increase of 0.5 °C, cognitive performance decreases.
Above 39 °C there is a risk of heat collapse or even life-threatening heat stroke.

“Deadly heat”: danger to life beyond core temperature
Through physical activity, people can maintain their core temperature relatively well between 35 and 37.5 degrees Celsius.
When the ambient temperature rises, people start to sweat.
The sweat in turn serves to cool you down.
If this range falls below or exceeds this range by just six degrees, there is a risk to life.
The examples mentioned in “Deadly Heat” are reality.
The climate thriller “The World Tilts” by Heiko von Tschischwitz is more fictional.
And Tim Smedley also impressively shows what lies ahead in “The Great Drought”.
But there are also books that show how to maintain hope in times of climate change and what you can do.
Hanns-Christian Gunga “Deadly Heat”: Conclusion
Hanns-Christian Gunga investigates common questions in “Deadly Heat”.
How can we avoid heat-related illnesses, who should we particularly protect and how does our body react to heat stress?
If some medical terms are difficult to understand, the book is a well-founded introduction to the topic, what to expect and how we can learn to deal with it.
