TL;DR30-second take

A Philadelphia winter storm kit covers heat, calories, water, and people. You need a Mr. Heater Buddy with a carbon monoxide detector, wool blankets, high-fat food, electrolytes, 5 gallons of drinking water per person, and a plan to check on older neighbors. Never run a generator or gas stove indoors.

When the radiant heat dies

In Philadelphia, winter is more than snow. It is infrastructure under stress. Old row homes lose heat fast. Pipes freeze inside outside walls. The grid in Fishtown and Kensington is famous for icing up during ice storms.

In Medicine 3.0, we plan for unlikely but high-impact events. A 3-day power outage in February is more than uncomfortable. For someone with diabetes, heart disease, or an older neighbor on the same block, it can be life-threatening. The goal is not just to survive. It is to keep your body in balance, what doctors call homeostasis.

The science: how the body handles cold

Your body burns more calories trying to stay warm than you might expect.

A few things happen at once when you get cold for a long time.

  • Brown fat thermogenesis. Brown adipose tissue (BAT) is a special kind of fat that burns sugar to make heat. When this kicks in, your blood sugar can drop quickly, particularly if you have not eaten.
  • Vasoconstriction. Cold air makes your blood vessels narrow to keep heat in your core. That raises your blood pressure, which is hard on your heart.
  • The hidden danger. In a 40°F house, an older adult can slip into hypothermia (a dangerously low body temperature) while sleeping under a thin blanket.

The Fishtown plan: shelter in place, the smart way

This is not a bunker. It is a practical city kit.

  1. Safe heat:

    • Mr. Heater Buddy (propane). Indoor-safe propane heater. The key word is with a carbon monoxide (CO) detector right next to it. CO is an odorless gas that can kill you in your sleep.
    • Wool blankets. Cotton holds moisture and stops insulating once it is damp. Wool keeps you warm even when wet.
  2. Steady calories:

    • Nut butter packets. High fat means slow, steady fuel and more body heat.
    • Canned sardines or tuna. Protein with no cooking required.
    • Electrolytes (LMNT or similar). You actually dehydrate faster in cold dry air, even when you do not feel thirsty.
  3. Water reserve:

    • The bathtub trick. Before a storm, fill the bathtub. That is your toilet-flushing water if pipes freeze.
    • Drinking water. Plan for 5 gallons per person.

The medical toolbox: medications and generators

Carbon monoxide is the silent killer of Philly winters.

ItemPurposeNote
Mylar thermal blanketReflects up to 90% of body heat back at you.Keep one in the car and one in the house.
GeneratorBackup power.Never run a generator inside a home, garage, or basement. The exhaust contains carbon monoxide. Keep it at least 20 feet from any door or window.
Insulin cooler (Frio)Medical necessity.If your fridge loses power, insulin can spoil. A Frio cooling wallet uses evaporation to keep insulin in range without electricity.
Hand warmers (HotHands)Targeted heat.Place at the femoral arteries (groin) or under the armpits. Warming the blood that flows through these areas helps warm the whole body.

Guidance from the clinic

Dr. Ash
"Check on Mrs. Graziano."

I have your back. At Fishtown Medicine, my job is not just to order tests and hand you a result. I interpret, I explain, and I push for the answer you actually need. You should feel like you have a Chief Medical Officer in your corner who fights for clarity and access, not just checkboxes.

"Dr. Ash, I'm fine. I have a North Face jacket."

My response is simple: "You are fine. Your 80-year-old neighbor is not."

In Philadelphia, community is our first survival tool. When the power goes out, older adults lose body heat faster, and many of them will not call for help. Knock on doors. Share your space heater. That is the Fishtown way.

Actionable Steps in Philly

Winterize the row home.

  1. Drip the faucets. When the temperature drops below 20°F, leave a faucet running at a slow drip on the wall furthest from your boiler. A burst pipe causes more damage than the water bill ever could.
  2. Seal the mail slot. The mail slot in an old row home door is a wind tunnel. Tape it shut from inside during a blizzard.
  3. Sign up for ReadyPhiladelphia. Real-time city alerts give you a head start before the grid goes down.

Stay warm. Stay safe.

Frequently Asked Questions

Common Questions

No, do not use your gas stove for heat during a Philly power outage. A gas stove was not designed to run for hours in a closed kitchen, and it produces carbon monoxide, an odorless gas that can kill you. Use a propane heater rated for indoor use, with a carbon monoxide detector nearby.
If your pipes freeze, do not use a blowtorch or open flame. Open the cabinet doors under the sink so warm room air can reach the pipes, and use a hair dryer or heat tape on the frozen section. If a pipe has already burst, shut off your home's main water valve before the thaw.
To stay warm without power, shrink the space you are trying to heat. Drape heavy blankets over a dining table to make a small fort, and gather everyone in there with extra layers. Body heat warms a small volume quickly. Sleep in the same room and consider sharing beds with family members or pets.
Insulin can sit at room temperature, between 59°F and 86°F, for up to 28 days. In a winter power outage, your home will likely stay in that range for a while, but a Frio cooling wallet adds a safety margin. If insulin has been frozen or has gotten very warm, call your pharmacy before using it.
No, it is not safe to run a generator inside a garage even with the door open. Carbon monoxide builds up faster than the open door can vent it, and people have died this way. Place the generator at least 20 feet from any door, window, or vent, and point the exhaust away from the house.
A simple knock and a "Hey, how are you holding up?" is usually enough. Offer to drop off a thermos of hot soup or to move them somewhere warmer if their heat is out. Most older adults appreciate the check-in once they know you are not selling anything.
A home indoor temperature below 60°F can be dangerous, particularly for older adults, infants, and people with heart disease. The CDC recommends keeping indoor temperatures at 68°F or above when you can. If the heat is out, plan to move somewhere warmer if the indoor temperature stays under 55°F for more than a few hours.
You should not shovel snow if you have known heart disease, high blood pressure that is not under control, or a strong family history of early heart attacks. Shoveling combines cold air, breath-holding strain, and heavy lifting, which is hard on the heart. See Snow Shoveling and Heart Risks for the full story.

Deep-Dive Questions

A propane Mr. Heater Buddy compares well to a kerosene heater for indoor row home use. Propane burns cleaner and produces less carbon monoxide for the same heat output, and the Buddy has an automatic shut-off if the oxygen level drops or the unit tips over. Kerosene puts out more heat per dollar but adds smell, soot, and a higher CO risk. For a small Philly row home, propane is usually the better pick.
Home pipes in Philadelphia can usually survive a few hours below 20°F before they start to freeze, particularly in older row homes with pipes inside outside walls. Insulating exposed pipes with foam sleeves, dripping faucets at night, and keeping the home above 55°F all extend that window. After 24 hours of single-digit weather, the risk goes up sharply.
If your SEPTA route is suspended, work from home if you can. SEPTA usually announces service holds the night before a major storm. If you have to travel, switch to a Regional Rail line, which often runs longer than buses and the trolleys. Check the SEPTA app for real-time updates, and dress for a cold wait.
Cold weather raises blood pressure by causing blood vessels to narrow, which is the body's way of conserving heat. For someone with high blood pressure or heart disease, that extra workload on the heart raises the risk of a heart attack, particularly with sudden exertion like shoveling. Hospital admissions for heart attacks rise predictably during cold snaps.
The Philadelphia Heater Hotline and weatherization programs are worth applying for if you qualify. They can repair or replace a broken heating system at low or no cost for income-eligible homeowners. Call 215-568-7190 for the Energy Coordinating Agency or visit the city's Office of Community Empowerment and Opportunity website.
If your elderly parent in Mayfair refuses to leave during a freeze, do not force them, but do not leave the situation alone either. Drop off blankets, a fully charged phone, a propane heater they know how to use, and a clear plan for them to text you every 4 hours. If they stop responding, call the Philadelphia Corporation for Aging at 215-765-9040 for a welfare check.
To prepare an elderly relative with dementia for a winter storm, focus on supervision, not just supplies. They may forget how to operate a space heater or may wander outside during a power outage. Stay with them through the storm if you can, set up a single warm room with familiar objects, and remove anything that could become a hazard, like loose space heater cords or open flame candles.
Battery-powered heated blankets are reasonably safe for an overnight outage if you use a name-brand model with overheat protection. Lithium battery packs do not produce carbon monoxide and are a great fit for power outages, but the heat output is much lower than an electric blanket on the wall. Pair one with a wool blanket on top for the best result.
Philly's row home design makes heating harder because shared walls only help when both neighbors are heating their homes. Many row homes also have single-pane windows, uninsulated outside walls, and old radiators on a one-pipe steam system. Adding cellular shades, weather stripping on doors, and a thermal curtain on the front door can drop your heating bill noticeably.
Call a doctor after cold exposure if you notice numbness or skin that turns waxy, white, or blue, particularly on fingers, toes, ears, or nose. New chest pain, severe shortness of breath, or confusion in an older adult after a cold day all need evaluation. For Fishtown Medicine members, you can text me first and we will sort out whether you need urgent care, the ER, or an office visit.
