Interventions

• CHARM HeatWise — BEHAVIORAL
  HEATWise consists of structured, facilitator-led training sessions on extreme heat preparedness and response, distribution of heat resilience kits, and community engagement activities designed to promote protective behaviors. The intervention is delivered at the cluster (site) level in community-based settings and focuses on reducing risk of heat-related illness and improving individual and community resilience.

Study Details

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.
