"We live here, we practice here and we do everything here," Gonzalez said.
With a high of 98 degrees on Thursday, the Braves cut 15 minutes off their batting practice. Gonzalez said they will likely have a similar schedule over the weekend.
If temperatures do rise above 100 in Atlanta this weekend, it will be the first time since August 2010 it has been that hot.
Gonzalez said he won't explicitly tell his team to hydrate, because there are already plenty of signs in the weight room and training room reminding them to do so.
Right-hander Tim Hudson is scheduled to start Sunday's game. After dealing with cramps multiple times in his career, he has taken to getting an IV before his starts to help stay hydrated.
"That's smart on his part," Gonzalez said. "He takes care of that, and I'm sure there's other guys that take heat precautions also."
Third baseman Chipper Jones said he will likely need to take one of the two day games off, and Gonzalez said catcher Brian McCann will also get a day off this weekend.
