Study Overview
Brief Summary
The goal of this clinical trial is to assess the effectiveness of an intervention (combination of behavioural recommendations and technical measures) in reducing personal exposure to heat and air pollution and related health effects in outdoor workers.
The main questions it aims to answer are:
- Does the intervention (combination of behavioral recommendations for heat mitigation) reduce personal ambient temperature exposure, measured using a wearable device (iButton)?
- Does the intervention (combination of behavioral recommendations for air pollution mitigation and use of indoor air cleaners) reduce indoor exposure to air pollution, measured using indoor air quality sensors (Purple Air)?
- Does the intervention (combination of behavioral recommendations for heat mitigation) reduce physiological strain experienced by individuals working in hot environments, measured using the Heat Strain Score Index?
Researchers will compare measurements between outdoor workers carrying out their activities in the absence of intervention (control group), those carrying out their activities with behavioural recommendations (recommendation intervention group) and those carrying out their activities with both behavioural recommendations for heat mitigation and continuous use of indoor air cleaners in their house (heat and air pollution mitigation intervention group) to see if changes in temperature exposure and physiological strain are different between intervention groups.
Participants will:
- Wear the wearable devise for continuous personal ambient temperature monitoring (ibutton) daily for a period of three months
- Have their core temperature measured using an eCelsius medical capsule in three repeated assessments
- Complete the Heat Strain Score Index questionnaire in three repeated assessments
- Provide samples of urine, blood, saliva and hair for measurement of various biomarkers in three repeated assessments

Arms & Interventions
Control group
Subjects in this arm will receive no alerts for high temperatures nor recommendations for mitigation of heat-related health effects.
Heat intervention - Personal Alerts and Specific Recommendations
Subjects in this group will receive timely personal alerts for high temperatures and specific recommendations to reduce exposure to heat and mitigation of heat-related health effects in written and animated format through mobile phones, mobile applications and online tools.
Intervention: Heat intervention (Other)
Heat and air pollution intervention - Group Alerts, Recommendations and Air Cleaners
Subjects in this group will receive alerts and recommendations as in group "Heat intervention" and in addition, continuously use of air cleaners with HEPA filter for removing PM from indoor air in their residences and workplaces to provide evidence for health benefits.
Intervention: Heat and air pollution mitigation intervention (Other)
Outcomes
Primary Outcomes
Not specified
Secondary Outcomes
- Sleep-wake time(Daily measurements - for the whole duration of follow-up (2 months))
- Sleep-Wake Time self-reported evaluation(The sleep-wake self-reported evaluation will be assessed at baseline, middle (after 1 month), and at end of observation period (after 2 months).)
