Doctor warns of excessive heat risks

SIOUX FALLS, S.D. (AP) - The hot temperatures and high humidity forecast for South Dakota over the next several days has one doctor warning residents to change their routines.

An excessive heat warning is in effect through Tuesday evening

for central and eastern sections of the state.

Sanford Health Dr. Mike Bergeron (BERZH'-er-on) tells South

Dakota Public Broadcasting that heat-related issues come in stages,

with early-onset heat exhaustion treatable with hydration and about

15 minutes of rest in a cool spot.

He says without relief, it can get worse and develop into

exertional heat stroke. A person who is rapidly overheating can

become combative, lose control or have a seizure or go into a coma.

Bergeron says be prepared with plenty of water, wet towels or

other methods to cool down.
