Heat in the Northeast has taken at least six lives, health officials say. Five have died in Maryland over the course of the summer of heat-related causes; one man died last week in New York.

A heat wave has been hanging over the northeast and the Midwest since early this week, driving up the heat index over 100 degrees in many places.

Extreme heat can be a major cause of death, and health officials warn that the elderly, children and people with cardiovascular conditions stay cool and drink plenty of water.
