Welcome Back!
We hope you are now a regular visitor, and find
our postings of interest, and useful.
Today, we are reproducing this article from a newsletter
alert of HSI, to which we subscribe.
We risk copyright infringement to bring this to you
but we feel it is extremely important information,
given the present heatwaves occurring around the world.
And, we do think of you as our extended family
whose health is important to us, and HSI did ask us
to share this with friends and family!
So here it is:
“Dear Reader,
As high temperatures hover around 100 degrees in many U.S.
locations this week, local television stations coast to
coast have been offering tips for avoiding heat-related
health problems. By now I’m sure you know the basic drill:
• Limit direct sun exposure
• Keep physical exertion to aminimum
• Drink plenty of water
• Avoid dehydrating beverages such as alcohol and coffee
• Eat light meals
To that list we can add one more tip: If you begin to feel
disoriented or nauseous, take immediate steps to cool off,
because a heat stroke can be just as dangerous as an
ischemic stroke. But what most people don’t realize is that
no matter what your age, the health consequences of a heat
stroke can linger long after summer heat waves have come and
gone.
————- Hot, hotter, hottest, —————
This past Monday, the National Weather Service issued an
Excessive Heat Watch for the United States, which stated:
“The combination of hot temperatures and high humidity will
combine to create a dangerous situation in which heat
illnesses are possible.”
That advisory included a forecast for Chicago that predicted
low temperatures in the high 70s and low 80s early in the
week. For lows, that’s pretty warm, but it’s nothing
compared to the heat wave of 1995. During that nine-day
grilling, there was a 48-hour period when the low
temperature in Chicago never dropped below 89 degrees.
Can you imagine? It’s the middle of the night, the sun’s
been down for hours, and it’s still nearly 90 degrees. This
is a weather event so rare that meteorologists say there’s
less than one percent chance of it ever happening again.
Which is good news because more than 600 people in the
Chicago area died of heat stroke in ‘95, and well over 3,000
with heat-related health problems were admitted to local
hospitals. Of those 3,000+, many ended up in intensive care
with near-fatal heat stroke
In 1998, University of Chicago Medical Center researchers
assessed 58 of the “near-fatal classic heat stroke”
patients. The subjects who survived were interviewed at the
time of their discharge from the hospital, and those who
were still alive one year later were interviewed again.
STUDY ABSTRACT
•All of the patients experienced multiorgan dysfunction and
neurologic impairment
•More than half experienced moderate to severe kidney
failure
•Nearly half experienced blood clots
•10 percent experienced acute respiratory distress
•21 percent died while in the hospital
•28 percent of the survivors died within one year, mostly
within the first three months
•Among the survivors at one year, substantial functional
impairment still persisted
———— No age discrimination —————
A sobering detail that stands out in the Chicago study is
the age factor. The elderly and infirm are generally at
greatest risk of heat stroke, but in the Chicago cohort age
was not a primary issue. Subjects ranged in age from 25 to
95, and the average age was 67.
As we press on through this unusually hot season, it’s
useful to know these warning signs of heat exhaustion and
heat stroke:
• Headache
• Nausea
• Disorientation
• Sweating stops
• Skin becomes flushed, hot and dry
As soon as these symptoms appear the victim must be cooled
immediately, with air conditioning, fans or lukewarm water.
Cold water should not be used because it may cause shivering
which raises body temperature.
I hope you’ll share this e-Alert with friends and family to
let them know that no matter how old you are the dire
effects of a heat stroke can extend well beyond these
uncomfortably hot days of summer.”
