Mitigation of Health Effects in Outdoor Workers by Reducing Exposure to Heat and Air Pollution (ISMED-CLIM OW)

2026년 6월 3일 업데이트: Panayiotis Yiallouros, University of Cyprus

Innovative Solutions Across the MEDiterranean for Mitigation of Climate Change-related heaLth rIsks in Outdoor Workers

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

Heat Strain Score Index
기간: The HSSI will be assessed at baseline, middle (after 1 month), and at end of observation period (after 2 months).
The Heat Strain Score Index (HSSI) is a questionnaire-based assessment tool used to assess the risk of heat strain on individuals exposed to hot environments, using a questionnaire. It integrates multiple factors, such as environmental conditions, work intensity, clothing, and physiological responses, to estimate the likelihood of heat stress affecting a person.
The HSSI will be assessed at baseline, middle (after 1 month), and at end of observation period (after 2 months).
