"Heat waves are the deadliest of extreme weather events, the Centers for Disease Control and Prevention reported this week."

"A case study published in the August 9 edition of the agency's journal, Morbidity and Mortality Weekly Report, looked at heat illness in New York City from 2000 to 2011. The results revealed that there were more than 150 deaths, about 1,600 hospitalizations and around 2,700 emergency room visits due to the extreme heat.

Heat waves are dangerous for everyone, but the elderly, children, the poor and those with pre-existing medical condition are particularly at risk. Those who have outdoor jobs like athletes and laborers are also in danger. ...

Overall, heat waves killed more people in the U.S. than any other extreme weather event, the CDC researchers reported."
