The investigators are studying the dangers that farmworkers face while working in the fields and at home. The investigators goals are: 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.

Primary | Individual heat stress | Skin temperature in degrees Celsius derived from skin temperature monitor worn against the participant's skin. | Assessment at baseline (pre-intervention) and again immediately (week) after the intervention | |
Primary | Participant household temperature | Household temperature in degrees Celsius, derived from weather monitor placed in the participant's home. | Assessment at baseline (pre-intervention) and again immediately (week) after the intervention | |
Primary | Participant hydration level | Specific gravity of participant's urine | Assessment at baseline (pre-intervention) and again immediately (week) after the intervention | |
Primary | Concentration of chemicals measured in silicon wristband worn by study participant | Participants will be asked to wear a silicon wristbands twice; once at baseline and again after the intervention. The research team will collect the wristbands and transport them to San Diego State University for analysis of different classes of chemicals, including pesticides, organophosphates, pyrethroids, and legacy pollutants. The chemicals adhered to the wristbands will be extracted in ethyl acetate and then passed through a solid-phase extraction. Extracts will be analyzed using a two-dimensional gas chromatography coupled to time-of-flight mass spectrometry at San Diego State University. The final concentration of each chemical will be expressed as nanograms per gram of wristband. | Assessment at baseline (pre-intervention) and again immediately (week) after the intervention | |
Primary | Concentration of chemicals measured in silicon wristbands hung in the participant's household. | Silicon wristbands will be hung in participants' homes twice; once at baseline and again after the intervention. The research team will collect the wristbands and transport them to San Diego State University for analysis of different classes of chemicals, including pesticides, organophosphates, pyrethroids, and legacy pollutants. The chemicals adhered to the wristbands will be extracted in ethyl acetate and then passed through a solid-phase extraction. Extracts will be analyzed using a two-dimensional gas chromatography coupled to time-of-flight mass spectrometry at San Diego State University. The final concentration of each chemical will be expressed as nanograms per gram of wristband. | Assessment at baseline (pre-intervention) and again immediately (week) after the intervention | |
Primary | Concentration of chemicals measured in participant's household dust collected with a vacuum | The research team will visit the participant's home twice to collect the dust samples of the living area using a vacuum; once at baseline and again after the intervention. After collection, the research team will transport the dust samples to San Diego State University to measure the concentrations of different classes of chemicals, including pesticides, organophosphates, pyrethroids, and legacy pollutants. The chemicals in the dust will be extracted in ethyl acetate and then passed through a solid-phase extraction. Extracts will be analyzed using a two-dimensional gas chromatography coupled to time-of-flight mass spectrometry at San Diego State University. The final concentration of each chemical will be expressed as nanograms per gram of dust. | Assessment at baseline (pre-intervention) and again immediately (week) after the intervention |
