Summary

Extreme heat events pose serious health risks, especially for communities with limited access to cooling, transportation, or social support. This study pilots and tests HEATwise, a heat preparedness program delivered at trusted community centers in Lake County, California, serving older adults, Tribal members, and people experiencing housing or economic hardship. HEATwise is a 12-week program which includes a group workshop on heat risks and preparedness, one-on-one resource navigation, a community celebration event, and a cooling and emergency supply kit. The pilot phase (2026) will assess feasibility and acceptability at three sites with approximately 60 participants. The full trial (2027-2028) will randomly assign eight sites to receive HEATwise immediately or after a delay, measuring whether the program increases protective behaviors, reduces heat-related symptoms, and strengthens resilience over 12 months.
