When watching Formula 1 races, it can be easy to forget how uncomfortably hot it can inside the drivers' helmets, especially when temperatures soar on track.
Mercedes driver Nico Rosberg has been trying to find a way to prevent sweat from trickling into his eyes, which is where women's sanitary towels come in.
Last year's championship runner-up has admitted to Sky Sports that he been using them to soak up excess perspiration from his brow.
"I have an issue with my eye when I sweat a lot so that is what the headband is for. Actually I do have sort of a headband in my helmet, it is my trick, but I can tell you," said the Mercedes driver.
"I put a woman's... erm... what do you call them? The thing you put in your underwear. Sanitary towel - I put that on my forehead in my helmet to take up the sweat."
