What
to do when the temperature is rising:
 |
Avoid prolonged exposure to sunlight
and strenuous outdoor physical activities…especially
in the afternoon…since heat or sun stroke
can occur quickly. Use sun block and drink plenty
of water. Also it is advised to check on those
more sensitive to heat…such as the elderly…children…and
pets. The hot…dry and breezy weather also
increases the fire danger. |

Tips
for staying cool during intense heat periods:
- Stay out of the sun
Avoid going outside during the hottest part of the
day, noon to 4 p.m.
- Limit your activity
Reserve vigorous exercise or activities for early
morning or evening.
- Dress properly
Wear a large-brimmed hat and light-colored, light-weight,
loose-fitting clothing that breathes. Don't go shirtless--a
sweaty shirt will keep you cooler than bare skin.
- Drink plenty of liquids
Fluids help you sweat, which is your body's way
of cooling off. Drink lots of water, juice or sports
drinks. Avoid alcoholic or caffeinated drinks that
promote fluid loss through urination.
- Avoid hot, heavy meals
They increase your metabolism, causing an increase
in your body temperature.
- Keep it cool
Set your air conditioner between 75 and 80 degrees
F. If you don't have an air conditioner, take a
cool bath or shower once or twice a day and visit
air-conditioned public places.
- Heat Cramps
Heat cramps are painful spasms of muscles along
with profuse perspiration, and occur most often
during exercise in high temperatures. The muscles
most affected are usually the ones you are using
during your exercise or your abdominal muscles.
You can usually resolve the symptoms by resting
and drinking water mixed with a teaspoon of salt
per quart.
- Sunburn
Prolonged exposure to the sun's ultraviolet rays
produces red, tender, swollen skin that may develop
water blisters. Severe cases of sun and heat exposure
can result in more serious consequences needing
emergency care. Sunburn happens relatively slowly,
but can be treated adequately at home with a cool
bath or shower followed by the application of hydrocortisone
cream several times a day. Do not break the water
blisters, but if they break on their own, remove
the skin fragments and use an antibacterial ointment
on the open areas. Dress them with clean gauze.
Taking aspirin several times daily will help alleviate
the general discomfort and may reduce swelling.
- Heat Stroke
The main indication of heat stroke is a fever of
105 degrees Fahrenheit with hot, dry skin. Other
signs include rapid heartbeat, rapid and shallow
breathing, either elevated or lowered blood pressure,
and confusion or unconsciousness. If you suspect
heat stroke, get the person out of the sun and into
a cool spot.
Cool the person by covering him or her with damp
sheets or spraying with water. Direct air onto the
person with a fan or a newspaper, and monitor the
person's temperature with a thermometer. Stop cooling
the person when his or her temperature returns to
normal. If breathing ceases, start mouth-to-mouth
resuscitation. Heat stroke is an emergency that
needs immediate medical attention.
- Heat Exhaustion
Heat exhaustion occurs when your heart and vascular
system do not respond properly to high temperatures.
The symptoms of heat exhaustion resemble shock and
include faintness, rapid heartbeat, low blood pressure,
an ashen appearance, cold clammy skin, and nausea.
If you suspect heat exhaustion, get the person out
of the sun and into a cool spot. Lay the person
down and elevate his or her feet slightly. Loosen
or remove most or all of the person's clothing.
Give the person cold (not iced) water to drink,
with a teaspoon of salt added per quart.
- Heat Rash
To prevent heat rash, also known as prickly heat,
use an air conditioner or fan and dress lightly,
preferable in clothing made from pure cotton. Cotton
allows sweat to evaporate more easily than most
synthetic fibers. If you do get heat rash, taking
frequent baths in lukewarm water can help relieve
symptoms. Calamine lotion may also help.

Preparing
for and coping with heat Doing too much on
a hot day, spending too much time in the sun or staying
too long in an overheated place can cause heat-related
illnesses. Know the symptoms of heat disorders and
overexposure to the sun, and be ready to give first
aid treatment.
- Contact your local emergency management office
or American Red Cross chapter for information on
extreme heat.
- Install window air conditioners snugly.
- Close any floor heat registers nearby.
- Insulate spaces around air conditioners for a
tighter fit.
- Use a circulating or box fan to spread the cool
air.
- Keep heat outside and cool air inside.
- Install temporary reflectors, such as aluminum
foil covered cardboard, to reflect any heat back
outside. Keep the cool air inside by weather-stripping
doors and windowsills.
- Consider keeping storm windows up all year. Storm
windows can keep the heat of a house in the summer
the same way they keep the cold out in the winter.
- Check air-conditioning ducts for proper insulation.
Top
Tips
for coping during a heat wave
- Protect windows. Hang shades, draperies, awnings,
or louvers on windows that receive morning or afternoon
sun. Outdoor awnings or louvers can reduce the heat
entering the house by as much as 80 percent. Conserve
electricity.
- During periods of extreme heat, people tend to
use a lot more power for air conditioning which
can lead to a power shortage or outage stay indoors
as much as possible. If air conditioning is not
available, stay on the lowest floor out of the sunshine.
Remember that electric fans do not cool, they just
blow hot air around.
- Eat well-balanced, light meals.
- Drink plenty of water regularly. Persons who have
epilepsy or heart, kidney, or liver disease; are
on fluid-restrictive diets; or have a problem with
fluid retention should consult a doctor before increasing
liquid intake.
- Limit intake of alcoholic beverages. Although
beer and alcohol beverages appear to satisfy thirst,
they actually cause further body dehydration.
- Dress in loose-fitting clothes that cover as much
skin as possible. Lightweight, light-colored clothing
that reflects heat and sunlight and helps maintain
normal body temperature.
- Protect face and head by wearing a wide-brimmed
hat.
- Allow your body to get acclimated to hot temperatures
for the first 2 or 3 days of a heat wave.
- Avoid too much sunshine. Sunburn slows the skin's
ability to cool itself. Use a sunscreen lotion with
a high SPF (sun protection factor) rating.
- Avoid extreme temperature changes. A cool shower
immediately after coming in from hot temperatures
can result in hypothermia, particularly for elderly
and very young people.
- Slow down. Reduce, eliminate, or reschedule strenuous
activities. High-risk individuals should stay in
cool places. Get plenty of rest to allow your natural
"cooling system" to work.
- Take salt tablets only if specified by your physician.
Persons on salt-restrictive diets should check with
a physician before increasing salt intake.
- Vacuum air conditioner filters weekly during periods
of high use.
- Learn the symptoms of heat disorders and know
how to give first aid.

Sunburn
Symptoms: Skin redness and pain, possible swelling,
blisters, fever, headaches.
First Aid: Take a shower, using soap, to remove oils
that may block pores preventing the body from cooling
naturally. If blisters occur, apply dry, sterile dressings
and get medical attention.
Top
Heat Cramps
Symptoms: Painful spasms usually in leg and abdominal
muscles. Heavy sweating.
First Aid: Firm pressure on cramping muscles or gentle
massage to relieve spasm. Give sips of water. If nausea
occurs, discontinue.
Top
Heat
Exhaustion Symptoms: Heavy sweating, weakness,
skin cold, pale and clammy. Weak pulse. Normal temperature
possible. Fainting, vomiting.
First Aid: Get victim to lie down in a cool place.
Loosen clothing. Apply cool, wet cloths. Fan or move
victim to air-conditioned place. Give sips of water.
If nausea occurs, discontinue. If vomiting occurs,
seek immediate medical attention.

National
Weather Service information on heat
Why
are Heat Waves so dangerous? Heat kills by
taxing the human body beyond its abilities. In a normal
year, about 175 Americans succumb to the demands of
summer heat. Among the large continental family of
natural hazards, only the cold of winter - not lightning,
hurricanes, tornadoes, floods, or earthquakes - takes
a greater toll. In the 40-year period from 1936 through
1975, nearly 20,000 people were killed in the United
States by the effects of heat and solar radiation.
In the disastrous heat wave of 1980, more than 1,250
people died. And these are the direct casualties.
No one can know how many more deaths are advanced
by heat wave weather - how many diseased or aging
hearts surrender that under better conditions would
have continued functioning.
Top
How does NOAA
keep the public informed about heat waves? With
the National Weather Service Heat Index Program, the
National Weather Service (NWS) has stepped up its
efforts to alert more effectively the general public
and appropriate authorities to the hazards of heat
waves - those prolonged excessive heat/humidity episodes.
Based on the latest research findings, the NWS has
devised the "Heat Index" (HI), (sometimes
referred to as the "apparent temperature").
The HI, given in degrees F, is an accurate measure
of how hot it really feels when relative humidity
(RH) is added to the actual air temperature.
IMPORTANT...Since HI values were devised for shady,
light wind conditions, EXPOSURE TO FULL SUNSHINE CAN
INCREASE HI VALUES BY UP TO 15 degrees F. Also, STRONG
WINDS, PARTICULARLY WITH VERY HOT, DRY AIR, CAN BE
EXTREMELY HAZARDOUS.
Top
Heat Index
How
does the NWS alert the public to the occurrence of
a heat wave?
The NWS will initiate alert procedures when the HI
is expected to exceed 105 degrees to 110 degrees F
(depending on local climate) for at least two consecutive
days. The procedures are:
- Include HI values in zone and city forecasts.
- Issue Special Weather Statements and/or Public
Information Statements presenting a detailed discussion
of
1. the extent of the hazard including HI values,
2. who is most at risk,
3. safety rules for reducing the risk.
- Assist state/local health officials in preparing
Civil Emergency Messages in severe heat waves. Meteorological
information from Special Weather Statements will
be included as well as more detailed medical information,
advice, and names and telephone numbers of health
officials.

How are
Heat Disorders related to the Heat Index? 130
degrees or higher: heatstroke/sunstroke highly likely
with continued exposure.
105 -130 degrees: sunstroke, heat cramps or heat
exhaustion likely and heatstroke possible with prolonged
exposure and/or physical activity.
90 -105 degrees: sunstroke, heat cramps and heat
exhaustion possible with prolonged exposure and/or
physical activity.
80 - 90 degrees: fatigue possible with prolonged
exposure and/or physical activity.
Top
What are
the signs of these heat disorders? SUNBURN:
Redness and pain. In severe cases swelling of skin,
blisters, fever, headaches. Ointments for mild cases
if blisters appear and do not break. If breaking occurs,
apply dry sterile dressing. Serious, extensive cases
should be seen by physician.
HEAT CRAMPS: Painful spasms usually in muscles of
legs and abdomen possible. Heavy sweating. Firm pressure
on cramping muscles, or gentle massage to relieve
spasm. Give sips of water. If nausea occurs, discontinue
use.
HEAT EXHAUSTION: Heavy sweating, weakness, skin cold,
pale, and clammy. Pulse thready. Normal temperature
possible. Fainting and vomiting. Get victim out of
sun. Lay down and loosen clothing. Apply cool, wet
cloths. Fan or move victim to air conditioned room.
Sips of water. If nausea occurs. discontinue use.
If vomiting continues, seek immediate medical attention.
HEAT STROKE or SUN STROKE: High body temperature
(106 degrees F or higher). Hot dry skin. Rapid and
strong pulse. Possible unconsciousness. HEAT STROKE
IS A
SEVERE MEDICAL EMERGENCY SUMMON EMERGENCY MEDICAL
ASSISTANCE OR GET THE VICTIM TO A HOSPITAL IMMEDIATELY.
DELAY CAN BE FATAL. Move the victim to a cooler environment.
Reduce body temperature with cold bath or sponging.
Use extreme caution. Remove clothing, use fans and
air conditioners. If temperature rises again, repeat
process. Do not give fluids.

Who
is most susceptible to heat related illnesses?
Elderly persons, small children, chronic invalids,
those on certain medications or drugs (especially
tranquilizers and anticholinergics), and persons with
weight and alcohol problems are particularly susceptible
to heat reactions, especially during heat waves in
areas where a moderate climate usually prevails.

What
can I do to prevent heat related illnesses?
Heat
Wave Safety Tips
- Reduce, eliminate or reschedule strenuous activities
to the coolest time of day. Individuals at high
risk should stay in the coolest available place(not
necessarily indoors)
- Dress in lightweight, light-colored clothing.
- Eat lightly
- Drink plenty of water or other non-alchoholic
beverages even if you don't feel thirsty. Persons
who have epilepsy, heart, kidney or liver disiase,who
are on fluid restricted diets or have a problem
with fluid retention should consult a physician
before increasing their fluid consumption.
- Do not take salt tables unless directed by a physician
- Spend more time in air-conditioned places.
- Don't get too much sun.
