Elderly people do not adjust as
well as young people to sudden changes in temperature.
They are more likely to have a
chronic
medical condition that upsets normal body responses to heat.
They are more likely to take
prescription medicines that impair the body's ability to regulate
its temperature or that inhibit perspiration.
Heat Stroke
Heat stroke is the
most serious heat-related illness. It occurs when
the body becomes unable to control its temperature: the body's
temperature rises rapidly, the body loses its ability to sweat, and
it is unable to cool down. Body temperatures rise to 106°F or higher
within 10 to 15 minutes. Heat stroke can cause death or permanent
disability if emergency treatment is not provided.
Signs and
Symptoms of Heat Stroke
Warning signs vary
but may include the following:
- An extremely high body
temperature (above 103°F)
- Red, hot, and dry skin (no
sweating)
- Rapid, strong pulse
- Throbbing headache
- Dizziness
- Nausea
Heat Exhaustion
Heat exhaustion is
a milder form of heat-related illness that can develop after several
days of exposure to high temperatures and inadequate or unbalanced
replacement of fluids.
Signs and
Symptoms of Heat Exhaustion
Warning signs vary
but may include the following:
- Heavy sweating
- Paleness
- Muscle Cramps
- Tiredness
- Weakness
- Dizziness
- Headache
- Nausea or vomiting
- Fainting
- Skin: may be cool and moist
- Pulse rate: fast and weak
- Breathing: fast and shallow
What You Can Do
to Protect Yourself
You can follow
these prevention tips to protect yourself from heat-related stress:
- Drink cool, nonalcoholic
beverages. (If your doctor generally limits the amount of fluid
you drink or has you on water pills, ask him how much you should
drink when the weather is hot. Also, avoid extremely cold
liquids because they can cause cramps.)
- Rest.
- Take a cool shower, bath, or
sponge bath.
- If possible, seek an
air-conditioned environment. (If you don't have air
conditioning, consider visiting an air-conditioned shopping mall
or public library to cool off.)
- Wear lightweight clothing.
- If possible, remain indoors in
the heat of the day.
- Do not engage in strenuous
activities.
What You Can Do
to Help Protect Elderly Relatives and Neighbors
If you have elderly
relatives or neighbors, you can help them protect themselves from
heat-related stress:
- Visit older adults at risk at
least twice a day and watch them for signs of heat exhaustion or
heat stroke.
- Take them to air-conditioned
locations if they have transportation problems.
- Make sure older adults have
access to an electric fan whenever possible.
What You
Can Do for Someone With Heat Stress
If you see any
signs of severe heat stress, you may be dealing with a
life-threatening emergency. Have someone call for immediate medical
assistance while you begin cooling the affected person. Do the
following:
- Get the person to a shady
area.
- Cool the person rapidly, using
whatever methods you can. For example, immerse the person in a
tub of cool water; place the person in a cool shower; spray the
person with cool water from a garden hose; sponge the person
with cool water; or if the humidity is low, wrap the person in a
cool, wet sheet and fan him or her vigorously.
- Monitor body temperature and
continue cooling efforts until the body temperature drops to
101°-102°F
- If emergency medical personnel
are delayed, call the hospital emergency room for further
instructions.
- Do not give the person alcohol
to drink.
- Get medical assistance as soon
as possible.
