Drivers lose up to 3kg (6.6lbs) of water weight through sweat during a single Grand Prix. The combination of heat, stress, and vibration actually suppresses the body’s digestive system. This is a survival mechanism; your body prioritises blood flow to muscles and brain, not your bladder.
Many drivers admit they don’t even need to go during a race. The sheer adrenaline and focus kill the urge completely. As former driver Mark Webber once joked, “You don’t feel your bladder when you’re trying not to crash at 200 mph.”
But what about the exceptions? What about the longest races or the extreme heat of Singapore or Bahrain? This is where the rumour gets a little more complex. Officially, no grid driver wears a diaper for performance.
The Emergency Protocol: The "Wee-Bag"
For outstanding circumstances, drivers have a discreet tool: a small, absorbent pad sewn into their fireproof underwear. Think of it as a high-tech, moisture-wicking reserve. It’s not a nappy—it’s a last-resort safety measure.
If the body’s suppression fails, and a driver can’t hold it, this pad is there to avoid a slippery mess in the cockpit. It’s designed to wick moisture away from the skin to prevent chafing and, more importantly, to avoid a short circuit in the car’s electronics. A wet seatbelt buckle is dangerous.

Fun fact: In 2004, driver Jarno Trulli famously used his own urine to cool his brakes during a pit stop. That’s not a thing anymore. The "wee-bag" is the modern, sterile solution.
