F1 Driver Reveals Sweat Detaches from Face at 7G Braking Forces

Discussing the Science Behind F1’s New Rule Changes (feat. Lewis Hamilton)
"7G is so hard that sometimes the sweating detaches from your body and sticks inside of the visor, you know. So it's— sometimes drivers think it's raining and it's not raining."
Ferrari driver Marc Gené disclosed extreme physical conditions drivers endure under the new 2026 regulations, explaining that braking forces exceeding 7Gs cause sweat to literally separate from their skin and stick to helmet visors. Drivers apply over 100 kilograms of force to the brake pedal in Miami, generating peak G-forces that briefly subject the body to seven times Earth's gravity. The phenomenon is so disorienting that pilots occasionally mistake detached sweat for rain.
