Heat danger is shaped not only by outdoor temperatures but also by whether people can afford and access reliable cooling.
Older housing, power outages, high electricity bills and limited air-conditioning leave low-income households, older adults, medically vulnerable people and isolated residents exposed. Examples range from Austin homes that become heat traps to Galveston households without air conditioning and senior residents in Texas’s Rio Grande Valley. Responses include LIHEAP assistance, weatherization, reflective roofs, efficient window units, cooling centers and community outreach, but institutional settings such as Texas prisons also show how inadequate cooling can intensify health risks.
