"The priority in Formula 1 is to be boxes and all these things in the cockpit because you can tidy the bodywork and give priority to the aerodynamics, which is obviously good," Alonso told media ahead of the United States Grand Prix.
"But in some cases, maybe Singapore, Miami or Qatar, it is something that we need to think about, and also with the racing kit, the overalls, the fireproof underwear it is very thick right now to be within the regulations after the Grosjean crash.
"It is very difficult because you need to have safe equipment for fire in case it happens, but that equipment in some conditions, in some races is just not evaporating the heat and it stays with you for the whole race, so the body cannot perform at its normal level."
"I think conditions [in Qatar] were too extreme to race, but obviously no one could anticipate it because Saturday was not that hot and humidity was much higher on Sunday, and the temperature as well so maybe it was a little bit of a surprise," he continued.
"We need to learn from this episode and were too on the limit for the physical aspect of drivers."
