It's hotter than normal, and it has been like this for several days. What you're experiencing is a heat wave. How did it form?



According to PPL, ideally, room temperatures should be kept below 89 degrees (F) during the day and 75 degrees (F) at night, and that's especially important for the most vulnerable.

NRG recommends controlling costs by following the four-by-four principle: setting your thermostat four degrees higher when you're away from home for more than four hours can help reduce electricity usage and costs.

The Philadelphia Corporation for Aging's Heatline is open from noon to midnight on Wednesday. It will also be open on Thursday from 8:30 a.m. to midnight. On Friday it will open at 8:30 a.m. and close at 8 p.m.

City health department nurses will be available to speak with callers about medical problems related to the heat.

"This could be the hottest week of the summer, so it's especially important for folks to try to get their loved ones - especially our elderly neighbors and family members - into air conditioning during the hottest part of the day. This could mean using the air in your home, your car, a business, or one of the City's cooling centers, being careful to follow COVID-19 precautions," said Acting Health Commissioner Dr. Cheryl Bettigole.

Though heat-related deaths and illness are preventable, the CDC says many people still succumb to extreme heat every year. Here's a look at the differences between heat stroke and heat exhaustion, and how to treat those affected.



City-run vaccine clinics may need to close early due to the heat health emergency. Call 311 or visit www.phila.gov/vaccine for updates or to reschedule your appointment.

The Department of Public Health recommends that to avoid heat-related illness, Philadelphians of all ages should:

- Use air conditioners. If necessary, go to an air-conditioned location for several hours during the hottest parts of the day. If you visit a public place with air conditioning, remember to wear a mask while inside and stay at least six feet away from anyone you don't live with.
- If using a fan, be sure to open windows to release trapped hot air.
- Drink plenty of liquids, especially water, to prevent dehydration. Avoid caffeine and alcohol.
- Never leave older people, children, or pets alone in cars.
- Those taking regular medication should consult with their physician. Some medications cause an adverse reaction in hot weather.
- Wear lightweight, light-colored clothing. When choosing a mask, make sure the material is also lightweight and breathable, like cotton.
- Avoid, as much as possible, working or playing in the hot sun or other hot areas, especially during the sun's peak hours of 11 a.m. through 4 p.m.
- Maintain a normal diet.
- Shower or bathe in water that is near skin temperature.
- Cover all exposed skin with an SPF sunscreen (15 or above). Wear a wide-brimmed hat to protect your face and head. Apply sunscreen under your mask to protect your face.
- 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. If there is no improvement, call a doctor or 911. City hospitals are ready and available to accept patients who need help.

Call 911 immediately if you have or you see others with serious signs of heat stress, including 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 person to a cool area, remove excess clothing, spray with water, and fan the person.

Helping the Pets



During excessive heat, all dogs must have one or more separate areas of shade large enough to accommodate the entire body of the dog at one time and protect it from the direct rays of the sun. Owners can face a $500 fine (and can put their pets in grave danger) if they don't follow ACCT Philly's requirements. To report a dog left outdoors in very hot weather, call (267) 385-3800.
