A crowd clad in blue waited outside Dodger Stadium on Monday, some with towels around their necks, others with cups of ice and bags of water bottles. Baseball fans braved record heat to watch the Dodgers play in the World Series for the first time since 1988.

The National Weather Service forecast office at LA sent out a red-flag warning, alerting residents about "record-breaking triple-digit heat" that is projected to reach 102 degrees.

Dr. Jonathan Sum, a board-certified sports clinical specialist at USC, said that the weather conditions might result in dehydration and other health issues related to an increase in core body heat.

"If the core body temperature increases, then the body is unable to provide enough oxygen to the muscles, the heart has to pump a little bit harder, some blood starts pooling into the limbs, and that is very detrimental to performance," said Sum, who works with physical training for the Los Angeles Angels' minor league team.

Fans are just as likely to feel the effects of the heat while in the stands. Sum explained that drinking alcohol and eating salty foods will amplify the effects of heat on the body.

"The temperature, the humidity and the number of people in the stands are going to increase their body temperatures and they're going to get dehydrated," Sum said. "Worst-case scenario is that because of heat, you would have some cardiovascular issues like strokes and heart attacks, just because the body is working so hard to keep itself cool."

Sum added that children are more at risk of suffering from dehydration because they have a harder time understanding when they are overheating.

A Dodgers fan who had been waiting outside the stadium since morning, Rick Mendoza, said that he had gotten used to the heat and that fans will watch anyway.

"Hopefully, they have enough gurneys in there, because those are diehards and they are going to go through it," said Mendoza.

Another fan, Norman Davis, said that fans would experience the heat differently based on where they sit.

"Heat is not that big of a deal. Once you get inside the Dodger Stadium, it just depends on what side of the stadium you're sitting on," Davis said.

Mendoza said he prepared for the day in the sun by bringing lots of water and a positive attitude.

"Splash some water, keep a towel and wipe the brow and enjoy it," he said.
