Sergio Perez believes Formula 1 should be "more efficient" with its scheduling, following a "super intense" 2023 season.
This year was supposed to see a record number of races at 24, but fell short when China was cancelled due to COVID restrictions and Imola was called off due to floods in Emilia Romagna.
George Russell raised concerns with how spending time in different time zones has impacted his heart rate, and now Perez wants to see more efficiency in the scheduling.
"More than other years, certainly I think this last part of the season has been super intense with the traveling backwards and forwards," Perez told media, including RacingNews365.
"The amount of races is definitely at the limit, not just for the drivers, but also for all the mechanics out there.
"This schedule, it really has to be more efficient and try to look after everyone in this world a lot more. My main concern is with my mechanics."

Perez: We should not add races for the sake of it
Next year there will be 24 races with the addition of Emilia Romagna and China, however there will also be back-to-back races at Las Vegas, Qatar, and Abu Dhabi to round off the season.
Daniel Ricciardo believes there needs to be a re-think, after concerns over the scheduling of the sessions in Las Vegas caused fatigue among teams.
With a race in Madrid also rumoured to be announced soon for the future, Perez does not want to see more races added for the sake of it.
"I think we just have to make sure that we keep delivering and we don't make a lot of races for the sake of doing them," said the Mexican.
"The quality level is still very important to having the score to make sure we keep this upward route."
