F1 set for extreme weather conditions at Singapore Grand Prix that spiked my heart rate to 207 BPM

Formula 1 has officially declared the Singapore Grand Prix a 'Heat Hazard' for the second consecutive year as drivers brace for extreme weather conditions. The designation mandates safety protocols, including the correct fitting of Driver Cooling Systems, with temperatures forecast to exceed 31 degrees Celsius alongside humidity levels topping 90 percent.

To understand the physical toll, talkSPORT writer Joe Brophy tested identical conditions inside an environmental heat chamber at the University of Roehampton. During a simulated 20-minute push session, Brophy's heart rate spiked to 207 beats per minute, his body temperature rose by over a degree Celsius, and he lost half a kilogram in fluids.
