    WEDNESDAY, April 23, 2014 (HealthDay News) -- The deaths of well-known people offer an opportunity to educate the general public about disease detection and prevention, a new study suggests. Researchers surveyed 1,400 American men and women after Apple co-founder Steve Jobs died of pancreatic cancer in 2011 and learned that more than one-third of them sought information about his cause of death or information about cancer in general soon after his death was reported.

    TUESDAY, April 22, 2014 (HealthDay News) -- Less than 10 percent of crimes committed by mentally ill people are directly linked to the symptoms of their disorders, a new study shows. "When we hear about crimes committed by people with mental illness, they tend to be big headline-making crimes, so they get stuck in people's heads," said study author Jillian Peterson, a psychology professor at Normandale Community College in Bloomington, Minn.

LOUISVILLE, KY (WAVE) - The extreme heat and high ozone are a double whammy for people with asthma. At Family Allergy and Asthma, doctors are warning patients about the risks of this deadly combo.  

Jessica Ball knows to keep her rescue inhaler handy at all times even though it has been a while since she has needed it. She remembered the time when an asthma flare sent her to the emergency room. "Scary, your throat feels like it's going to close and just everything feels like it's closing in on you," said Ball.

"Anytime you have an ozone alert day anybody with respiratory problems is at risk to have more problems," said Dr. James Sublett. "There is plenty of evidence that shows relationships to ozone alerts and pollution alerts, you have more emergency room visits and more respiratory deaths during that time period."

When the heat gets up to 104, the simple act of breathing can no longer help to keep the body cool. "Core body temperature 104 and above is considered heat stroke, so if your outside air is 104 degrees you can't lose heat in that environment," Sublett said.

He advised to drink plenty of fluids before you get thirsty. If you wait until you are excessively thirsty, the body may lose its ability to sweat causing heat stroke.

To avoid heat stroke, try to stay inside in the air conditioning as much as possible and avoid all outdoor exercise in this kind of heat.

Symptoms that need urgent care include shortness of breath and the inability to move air in or out and chest tightness.
