Yes hot water explosions scare me rofl….

Explosions cause blast-induced traumatic brain injury (bTBI) through shockwaves that damage neurons, blood vessels, and the blood-brain barrier, leading to inflammation, edema, and long-term issues like cognitive deficits and PTSD. Future temperature changes, driven by climate warming, impair brain function by reducing cerebral blood flow, exacerbating neuroinflammation, and worsening conditions such as epilepsy, stroke, multiple sclerosis, Alzheimer’s, and Parkinson’s via mechanisms like hyperthermia and oxidative stress.[cen.acs +1]

Blast Effects

Primary blast waves from explosions generate rapid pressure changes that shear brain tissue, disrupt axonal integrity, and trigger tau protein accumulation similar to chronic traumatic encephalopathy. Secondary effects include contusions from debris, while tertiary impacts cause diffuse axonal injury; all contribute to acute symptoms like concussion and chronic neurodegeneration.[medicine.yale]

Heat Impacts

Rising temperatures elevate core body and brain heat, activating heat-shock proteins and TRPV4 channels in the hippocampus, which impair memory, cognition, and seizure thresholds—effects amplified in vulnerable populations like the elderly or those with pre-existing neurology. Hyperthermia breaks down the blood-brain barrier, allowing toxins to inflame microglia and astrocytes, while chronic exposure correlates with higher neurodegenerative mortality rates.[pmc.ncbi.nlm.nih +3]
