Due to concerns over summer temperatures across the USA, Mexico and Canada, FIFA has introduced two compulsory three-minute hydration breaks per match, scheduled around the 22nd minute of each half regardless of weather conditions.
Speaking ahead of Belgium's Group G opener against Egypt in Seattle, Garcia acknowledged the importance of player welfare but was unsure whether the breaks are necessary in every match.
"For me it's a coaching break rather than a cooling break. Maybe if we are in a good moment and flow maybe the break can interrupt this, but we will see."
Garcia added that water breaks will come in handy when they face Egypt where temperatures are expected to shoot up to 30 degrees for the lunch time kick-off.
"The weather will be really hot tomorrow, and maybe this hydration break will also be important for the grass."
Belgium skipper Youri Tielemans was also split down the middle when he offered his opinion about the decision by FIFA at this World Cup.
Meanwhile, Tielemans hopes his experience in winning the UEFA Europa League with club side Aston Villa can play a role in edging Belgium closer to a world title.
"I think it's mostly about belief because the tournament is a month long. Obviously the Europa League was an amazing experience, but it's a different competition over here. The stakes are very high and you can tell that every first game is nervy and very intense."
