It’s Not So Much the Heat, It’s the Lack of Power

MONDAY, July 2 (HealthDay News) — It’s bad enough that a
record-breaking heat wave is throttling the eastern half of the United
States, but millions of people have no electrical power to help them cope
with the searing temperatures.

An estimated 2 million customers from North Carolina to New Jersey and
as far west as Illinois had no power Monday morning, USA Today
reported, and utilities companies said the power outage could last several
more days.

Without power, people are struggling to cope with the dangerously high
temperatures, unable to follow standard advice that includes retreating to
the air conditioning or using fans to keep cool.

Dr. Robert Glatter, an emergency physician at Lenox Hill Hospital in
New York City, advises cooling off in a pool or other body of water. He
also advises drinking plenty of water throughout the day to prevent
dehydration.

“Don’t just drink when you are thirsty — keep ahead of your thirst and
drink consistently throughout the day,” he said.

Sports drinks that contain electrolytes such as sodium and potassium
with small amounts of glucose may help combat dehydration, Glatter noted,
but caffeinated beverages and products with high amounts of sugar can
worsen dehydration.

Because children and the elderly are particularly vulnerable to
dehydration, they should be checked on often and encouraged to drink lots
of fluids, he added.

Signs that you are overheated or at risk for a heat-related problem
include dizziness, nausea and headache. If children or the elderly have
any of these signs, they should go to an emergency room for medical
attention.

“If people have an elevated temperature and are confused, it is
important not to administer things like Advil, Tylenol or aspirin, because
these medicines can worsen heat stroke,” Glatter said. “Don’t give
medicines that lower temperature for a heat-related emergency.”

If you have power but no air conditioning, you can spray your body with
water and sit in front of a fan to keep cool, he said.

Many seniors take medications that hamper the body’s ability to cool
itself through sweating, including diuretics and some blood pressure
drugs. People who are overweight also may be prone to heat sickness
because of their tendency to retain more body heat, according to the U.S.
Centers for Disease Control and Prevention.

Wear loose, light-colored clothing and a wide-brimmed hat to shield
yourself from the sun’s rays if you have to spend time outdoors, Glatter
said.

The CDC recommends a “buddy system” when working in the heat, to
monitor the health of your co-workers and have them do the same for you.
Heat-induced illness can cause a person to become confused or lose
consciousness, and you should call 911 immediately if you see this
happening.

Even short periods of hot temperatures can cause serious health
problems, so the CDC recommends listening to local media reports or
contacting local health departments for safety updates. Overexerting
yourself on a hot day, spending too much time in the sun or staying too
long in an overheated place can cause heat-related illnesses.

According to the CDC, there are several types of heat illnesses that
you need to watch out for, both in yourself and others:

  • Heat stroke happens when the body can’t regulate its own
    temperature. You lose your ability to sweat, and your body is unable to
    cool down. Your body temperature may rise to 106 degrees Fahrenheit or
    higher in the space of 10 to 15 minutes. Heat stroke can cause death or
    permanent disability if emergency treatment is not given. Symptoms include
    red, hot, dry skin; a rapid and strong pulse; a throbbing headache;
    dizziness; nausea; and confusion. Once these symptoms occur, the victim
    has to be cooled rapidly using whatever methods you have, which include
    putting the person in a cool tub of water or a cool shower, spraying the
    person with a hose or wrapping the victim in a cool sheet. Do not give the
    victim fluids to drink, and get medical help as soon as possible.
  • Heat exhaustion is a milder form of heat illness that can
    develop after several days of exposure to high temperatures and lack of
    fluids. Those most prone to heat exhaustion are elderly people, those with
    high blood pressure and people working or exercising in a hot environment.
    Symptoms include heavy sweating, paleness, muscle cramps, fatigue,
    dizziness, headache, nausea, vomiting and fainting. The skin may be cool
    and moist and the pulse rate fast and weak while breathing may be fast and
    shallow. Help cool off the victim, and seek medical attention if symptoms
    worsen or last longer than an hour.
  • Heat cramps typically happen after you sweat a lot during
    strenuous activity. The cramps also may be a symptom of heat exhaustion.
    Cramps symptoms include muscle pains or spasms — usually in the stomach,
    arms or legs. You should stop all activity immediately and sit down in a
    cool place if you experience cramps. Drink clear liquids or sports drinks,
    and do not return to strenuous activity for a few hours. Seek medical
    attention if the cramps do not stop within an hour.
