WASHINGTON, D.C. (WUSA) --Thousands are sweating it out on the National Mall for the Folklife festival.
A first aid tent is set up, along with water stations so people can fill up their bottles for free.
Marcus Schilling from South Carolina is carting his three children around.
'I don't know if my body can take it.'
Becky Haberacker with the festival says there are emergency personnel and volunteers patrolling and keeping an eye on overheated visitors.
'we encourage people to take it easy, sit down on the bench and listen to some music.'
About 20 to 30 people visited the first aid tent because of heat exhaustion and other injuries Friday. None had to be transported.
DC Fire says they ran roughly 10 heat related calls. They say people seem to be heeding their warnings about the dangers of the sweltering heat.
