How to Survive a #Blackout in a #HeatWave
No matter where you live, you should #BePrepared to live without power during #ExtremeHeat.

"At the most basic, the emergency agencies that informed this article — primarily American Red Cross, Centers for Disease Control and Prevention, and Ready.gov, all of which can be consulted for further resources — say you should have an emergency kit prepared and up to date in your home, and sign up for emergency alerts. (Also prepare a separate emergency kit for your pets if you have any.) This should include directions to your local cooling center in addition to a hospital.
"Next, 'Take an inventory of your essential electrical needs,' advises the American Red Cross. 'Then consider how you would live without them when the power goes out.' That list might include backup batteries for phones, fans, CPAP machines, or any other medical devices.
"Also consider buying misting spray bottles (we’ll get to those later) and a cooler where you can stash food if the refrigerator goes down. Battery-operated fans can additionally be useful to have on hand, particularly in humid areas, despite many public health organizations warning against them. Extra gallons of water are a part of every emergency kit, and important to have on hand as well.
"The first thing you want to do if the power goes out during a heat wave, regardless of how severe you anticipate the situation being, is prevent the loss of whatever cool air there still is inside your house. At the most basic, this means covering your windows to keep out sunlight by drawing the blinds.
"If you anticipate the power being out for more than a few hours — perhaps because one of the emergency alerts you signed up for warns you the blackout could last for days — take more dramatic measures, like using blackout curtains if you have them, or reflective, foil-covered pieces of cardboard in the windows to bounce heat off your home. The most important thing, though, is to get the windows covered with something; even a towel will do if you don’t have drapes or blinds. If you have a multi-story home and anticipate a long-lasting power outage, begin to shut upstairs doors (hot air rises!) with plans on keeping those rooms closed off for the duration of the blackout. Any particularly drafty doors or windows can be further sealed with a rolled-up towel. In a worst-case-scenario event, you’ll be staying downstairs until your air conditioning turns back on, so keep that in mind as you move through the rooms.
"As you’re making your sweep, also snag any medications you have stored, since heat can alter their efficacy. Many meds will become less potent or altered when exposed to high temperatures; aspirin, for example, breaks down into acetic acid and salicylic acid, which can upset the stomach.
"Preventatively turn off and disconnect appliances, too, in order to avoid damage from a surge when the power returns (this is generally good advice no matter what the blackout conditions are). Then establish yourself in your darkest, coolest room — it’s likely on the north side of your home or apartment. Generally avoid south-facing rooms, followed by east- and west-facing rooms, since they get the most sunlight. Hunkering down in the basement is also potentially a good option.
"Keep your refrigerator closed until about four hours have passed, at which point you should move the contents and stash them in a cooler. A full freezer can stay at a safe temperature for up to 48 hours, but as FoodSafety.gov will remind you, 'when in doubt, throw it out.'
"Keep in mind your own vulnerabilities to heat, too: The elderly and the prepubescent are most at risk, but people taking antidepressants, antipsychotics, anticholinergics, diuretics, and ACE inhibitors can all have severe heat intolerance, too, Yale Climate Connection observes. Additionally, the publication notes, certain diabetes medications, including insulin, can be less effective when exposed to high heat. People with heart disease, kidney issues, or diabetes should be especially cautious about their health during heat waves because of the intense strain on these systems.
"If the temperature starts to climb inside your home during a power outage, it is imperative to act quickly to stay healthy. Drink lots of water, but do so consistently, not in guzzling bursts; we’re limited in how much water we can absorb by how fast our kidneys can function. In extreme conditions, the body can absorb up to a liter of water per hour, but it’s often much less. It’s more important, then, to sip continually throughout the day."
