Thousands of people will descend on Chicago this weekend for Lollapalooza, a four-day music fest in Grant Park.
Unfortunately, some may wind up sick from dehydration or sun exposure — last year, more than 230 people were taken to the emergency room.
Dr. Samuel Grief of the University of Illinois at Chicago shares tips on how to stay healthy at Lollapalooza, which runs from Thursday to Sunday.
GUEST: Dr. Samuel Grief, UIC associate professor of clinical family medicine
