concept in environmental psychology  that suggests a correlation between  

higher temperatures and increased  aggression or violent behavior.

This hypothesis is rooted in the  observation that as the mercury rises,  

so too might the tempers of individuals.

The proposed mechanism behind this  phenomenon involves the discomfort  

and irritability caused by excessive heat,  

which can lead to lowered self-control  and an increase in aggressive responses.

Research supporting the Heat Hypothesis indicates  that in hotter weather, people are more likely  

to experience psychological distress, which  can manifest as hostility or aggressive acts.

This has been observed in various settings,  

including urban environments where heat can  exacerbate the stress of crowded conditions.

Studies have also shown that crime rates,  

particularly for violent crimes, tend  to increase during warmer periods.

This hypothesis has important implications  for urban planning and public health,  

especially in the context of global warming,  suggesting that as global temperatures rise,  

so could levels of societal aggression.
