We could see some of the hottest weather of the year this week. Experts say it's important to know how your body reacts in the heat. 

"The biggest thing you're going to notice when you start to experience heat exhaustion is you're going to feel lightheaded, dizzy, nauseous," said Ryan Ramsdell, Paramedic Supervisor with REMSA. "You'll also notice that if you're really, really sweaty, then all of a sudden you stop sweating, that's a late sign in heat exhaustion."
Ramsdell says it's better to eat smaller meals during the day instead of a big meal because your body will produce less heat energy that way. 

Avoid drinks with high caffeine, or alcohol because they tend to dehydrate you faster.
Wear light-colored, loose fitting clothing.
Check on high risk people in your life, such as the elderly. That includes friends, family, and neighbors.

While some people beat the heat by staying indoors with air conditioning, others have to work in the triple digit heat. For construction workers they really have to be careful working outside, Granite Construction teaches their employees the signs of heat exhaustion so they can be aware when it starts happening to them or a co-worker. They also make sure they stay hydrated during the hot weather, "Hydration, whether it would be electrolytes or water, we supply all the water. They take breaks and we provide shade for them," says Granite employee Bob Johnson.  

The best piece of advice: if you can, avoid being outdoors all together. But on the weekend, we found several people trying to stay cool outdoors. 

The Reno Fire Department was spraying kids with water, outside of Greater Nevada Field. People inside the stadium are trying to keep cool too. 

"Drinking a lot of water, hats, sunscreen, block the sun," said Dani Velasquez. 

The Truckee River is a very busy spot with people swimming, rafting and kayaking Sunday afternoon..

"We thought we had it, but we did fall in," said Cassia, who was rafting Sunday afternoon with her friend. "It was fun and it doesn't feel all that hot because we were in the water most of the time."

With the water levels a lot lower than what they were earlier this month, the Reno Fire Department says it's safe to float the river. However, it's a good idea to have the right kind of raft and to wear a helmet while doing so.
