A recorded talk by Dr. Dawn-Elise Snipes describing how prolonged daily exposure to high ambient heat harms mental health and cognition and offering 20+ practical tips to reduce heat-related harm. Key mechanisms presented: impaired sleep and HPA-axis (stress) activation; dehydration and electrolyte imbalance; altered neurotransmitters (serotonin) and hormones (thyroid, cortisol); increased blood–brain barrier permeability; and medication–heat interactions that change drug plasma levels and impair thermoregulation. The talk highlights vulnerable groups (people on psychotropic or other medications, outdoor workers, people with dementia, low-SES households during brownouts) and gives concrete, low-cost mitigation strategies (fans with frozen bottles, cool compresses, hydration with electrolytes, minimizing indoor heat sources, community cooling sites, checking meds with a clinician, and animal care).
