Not only are the temperatures in the hundreds this week in Bakersfield, but the air quality is also at an unhealthy level.
Dr. Aboeed is a pulmonary and critical care specialist at Kern Medical. He suggests thinking twice before going to exercise outdoors.
"I encourage most of my asthmatic patients and those who have COPD, to avoid outdoor exercise.
However, that doesn't hold everyone back from wanting to hit the outdoors running.
Chase Gonzales is at the Panorama Trail in Bakersfield to catch Pokemon. He has severe asthma and although being outside worries him, he says it doesn't affect him too much.
"Well I actually have really severe asthma so I try to pay attention to it. Its definitely a concern especially being hot, walking around out here."
Others exercising on the trail say that if the air quality got worse enough they would consider staying indoors or going to a gym.
Regardless of where people decide to exercise, it is always a good idea to remain hydrated by drinking a sufficient amount of fluids.
