Scientists discovered the unexpected negative impact of heat on the human body

A new study conducted by Australian scientists has shown that global warming can seriously affect people's mental health.
According to the analysis, if drastic measures against climate change are not taken, by 2050 the number of mental and behavioral disorder (MBD) cases may increase by nearly 49%.
This was reported by the journal Nature Climate Change.

During the study, medical data collected in Australia between 2003 and 2018 was analyzed.
Experts found a direct connection between heat levels and hospitalizations related to MBD.
Cases such as depression, anxiety, schizophrenia, and drug addiction spiked during heat waves.

For example: during a 15-day heatwave in Adelaide in 2008, hospitalizations among children increased by 64%, and among the elderly by 10%.

Even in a relatively moderate warming scenario (less than 3°C by 2100), mental health disorders in Australia are expected to rise by 11% by the 2030s, and by 27.5% by the 2050s.

If heat intensifies, the increase may reach nearly 49%.
The risk is especially high in regions historically unaccustomed to hot weather.

Why does heat affect us?

The consequences are clear: heat disrupts sleep, increases stress levels, and reduces oxygen delivery to the central nervous system.
This worsens existing mental illnesses.

Young people are especially at risk — they often work outdoors and take fewer precautions.

According to researchers, protecting mental health should be a priority in the climate change adaptation process.

Otherwise, increasing heat may place a significant burden on the mental well-being of the entire society. Read 'Zamin' on Telegram!
