𝗜𝗺𝗽𝗮𝗰𝘁 𝗼𝗳 𝗪𝗼𝗿𝗸𝗽𝗹𝗮𝗰𝗲 𝗧𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲 𝗼𝗻 𝗪𝗼𝗿𝗸 𝗧𝗶𝗺𝗲 𝗟𝗼𝘀𝘀 There are moments in your career when you feel an extra sense of pride, and today is one of those days. Our study, which began as my first-ever research project in 2016 and involved nine years of data collection, is finally published. Hundreds of early mornings — waking up at 01:00, 02:00, 03:00, or 04:00 AM — just to be at the worksite before the shift started, ensuring everything was set up perfectly. Long days of data collection, followed by packing up and catching just a few hours of sleep before the next shift. Data were collected 𝗮𝗰𝗿𝗼𝘀𝘀 𝗺𝘂𝗹𝘁𝗶𝗽𝗹𝗲 𝗰𝗼𝘂𝗻𝘁𝗿𝗶𝗲𝘀 𝘄𝗼𝗿𝗹𝗱𝘄𝗶𝗱𝗲, involving 𝗵𝘂𝗻𝗱𝗿𝗲𝗱𝘀 𝗼𝗳 𝘄𝗼𝗿𝗸𝗲𝗿𝘀, 𝗼𝘃𝗲𝗿 𝟲𝟬𝟬 𝗳𝘂𝗹𝗹 𝘀𝗵𝗶𝗳𝘁𝘀, 𝟭𝟲 𝗻𝗮𝘁𝗶𝗼𝗻𝗮𝗹𝗶𝘁𝗶𝗲𝘀 🇦🇱 🇧🇩 🇨🇾 🇪🇬 🇬🇭 🇬🇷 🇮🇳 🇰🇪 🇳🇵 🇳🇮 🇵🇭 🇷🇴 🇸🇮 🇪🇸 🇻🇳 and 𝗺𝗼𝗿𝗲 𝘁𝗵𝗮𝗻 𝟱𝟬 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝗼𝗰𝗰𝘂𝗽𝗮𝘁𝗶𝗼𝗻𝘀. In total, over 𝟭𝟲 𝗺𝗶𝗹𝗹𝗶𝗼𝗻 𝘁𝗶𝗺𝗲 𝗽𝗼𝗶𝗻𝘁𝘀 were video-recorded and analyzed 𝘀𝗲𝗰𝗼𝗻𝗱 𝗯𝘆 𝘀𝗲𝗰𝗼𝗻𝗱. At the end of the day, every effort was worth it. Our findings now quantify the impact of workplace temperature - whether cold or hot - on work time loss. We reveal a U-shaped relationship: ✅ The 𝗹𝗲𝗮𝘀𝘁 𝘄𝗼𝗿𝗸 𝘁𝗶𝗺𝗲 𝗹𝗼𝘀𝘀 occurs at 𝟭𝟴°𝗖 (𝟲𝟰°𝗙). 📉 𝗪𝗼𝗿𝗸 𝘁𝗶𝗺𝗲 𝗹𝗼𝘀𝘀 𝗶𝗻𝗰𝗿𝗲𝗮𝘀𝗲𝘀 𝗳𝗼𝗿 𝗲𝘃𝗲𝗿𝘆 𝗱𝗲𝗴𝗿𝗲𝗲 𝗮𝗯𝗼𝘃𝗲 𝗼𝗿 𝗯𝗲𝗹𝗼𝘄 𝘁𝗵𝗶𝘀 𝗼𝗽𝘁𝗶𝗺𝗮𝗹 𝘁𝗲𝗺𝗽𝗲𝗿𝗮𝘁𝘂𝗿𝗲. In our paper, we introduce the 𝗪𝗼𝗿𝗸𝗽𝗹𝗮𝗰𝗲 𝗘𝗻𝘃𝗶𝗿𝗼𝗻𝗺𝗲𝗻𝘁𝗮𝗹 𝗟𝗮𝗯𝗼𝗿 𝗟𝗼𝘀𝘀 (𝗪𝗘𝗟𝗟) 𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝘀, which describe work time loss based on air temperature and WBGT, accounting for average, more susceptible, and less susceptible workers.
