Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
1. Measure how much heat and chemicals farmworkers in Imperial County are exposed to.
The investigators will ask the participants to wear a special belt under their clothes during work to measure heat. The investigators will also put two small temperature monitors in the participant's home for a day. The investigators will collect a urine sample to check hydration, and also measure the participants height, weight, blood pressure, and some blood markers for diseases using a simple finger-prick test.
To measure chemicals, the investigators will give the participants a wristband to wear for a week and hang another in the participants home. The investigators will also collect dust from each participant's home with a vacuum. Then, the investigators will analyze everything at San Diego State University.
After collecting samples, a trained community health worker will ask the participants a few questions about their work, lifestyle, health symptoms, and any hazards they face. The investigators will meet the participants twice at their homes to distribute the tools which will later be collected. Once the tools are collected, the investigators will have the chance to follow up with the participants if they have any questions.
2. Provide help to lower heat and chemical exposure with the help of community health workers.
3. Measure heat and chemicals again using the same methods to see if the project made a difference.
4. Talk to participants about what they liked and how the investigators can make future projects better.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
All participants
All participants will receive the intervention
Education and resources provided by community health workers
The intervention will consist of implementing existing tools provided by EPA's Design for the Environment program, CalOSHA and NIOSH sector-specific guidance for agricultural workers, the Imperial County Department of Public Health and materials from California Department of Toxics Substances Control. The investigators will utilize and adjust existing educational tools such as the Heat Illness Prevention plan developed by CalOSHA. In addition to the educational materials, the investigators will give each farmworker cooling working gear to be worn during their work-shift with (specialized clothes that has been used in other occupational settings). The investigators will provide all participants with a low-cost fan filter, known as Corsi-Rosenthal box built jointly by the community health/research team to reduce chemicals at home, and a small A/C unit to reduce heat stress.
