There is straightforward physiology behind why extreme heat elevates agitation, shortens tempers, and drains focus:
Biological Stress Response: When your body works in overdrive to regulate temperature, your nervous system responds similarly to a threat. Heart rate rises and cortisol spikes, which your brain interprets as anxiety or physical tension.
Neurotransmitter Disruption: High ambient heat impairs the regulation of serotonin and dopamine, lowering your natural threshold for frustration and distress tolerance.
Sleep Architecture Breakdown: High night temperatures prevent your core body temperature from dropping, which is required for deep REM sleep. You start the day with compromised cognitive bandwidth before you even step outside.
Recognizing heat as a physical stressor makes it easier to understand why minor frustrations feel magnified right now.
