An excessive heat advisory has been issued for Philadelphia tomorrow from 11 a.m. to 6 p.m. Temperatures in the lower 90s combined with high humidity will create hazardous conditions in Philadelphia and surrounding areas, the National Weather Service reported.
Conditions are not expected to be extreme enough or last long enough to require launch of the city’s Heatline or other special heat-response programs, according to city Health Commissioner James Buehler.
People should avoid the sun as much as possible, open windows to release trapped hot air, make use of fans and air conditioners, and drink plenty of non-alcoholic liquids to avoid dehydration.
The health department recommends showering or bathing in water that is near skin temperature and advises against leaving older people, children or pets alone in cars.
People taking regular medication should consult with their physician because some medications can cause an adverse reaction in hot weather.
The early warning signs of heat stress are decreased energy, slight loss of appetite, faintness, lightheadedness and nausea. People experiencing these symptoms should go to a cool environment, drink fluids, remove excess clothing, and rest.
Serious signs of heat stress include unconsciousness, rapid heartbeat, throbbing headache, dry skin, chest pain, mental confusion, irritability, vomiting, diarrhea, muscle cramps, staggering, and difficulty breathing. People experiencing these symptoms should get immediate medical attention.
While waiting for help, move the patient to a cool area, remove excess clothing, spray with water, and fan the person. In an emergency, dial 911.
