Logan Sargeant has revealed that he is now making use of his drinks bottle after opting not to do so for much of his rookie season.
Drivers are equipped with a drink system that they utilise during the race to stay hydrated amid the physical challenge.
However, Sargeant declared before the Singapore GP -widely regarded as the toughest challenge for drivers - that he hasn't been using his system for the entire year, insisting that he “lives with the fact that I hydrate before the race”.
In Qatar last time out, Sargeant retired from the race due to feeling unwell amid the scorching heat and sustained high g-forces the drivers were subjected to.
Several drivers displayed signs of heat exposure following the chequered flag, with some checking themselves into the medical centre, including Sargeant who was suffering from severe dehydration.
Speaking to media including RacingNews365 ahead of his home race in the United States, Sargeant revealed that he has been using the drinks bottle for a number of races.
“I have been using the drinks bottle from Singapore onwards,” he explained.
“To be honest, in that heat [of Qatar] it wasn't really helping much. I mean, it was burning hot water.
"The seat [as well] was boiling, blistering hot. It was just a tricky one. It wasn't ideal."
The FIA has since announced it will be launching an investigation in the circumstances of Qatar, in which Esteban Ocon explained he was throwing up in his helmet while Lance Stroll claimed to be losing consciousness such were the extreme conditions.
