With the temperatures rising and summer now upon us we have got to be more cautious and think, I myself almost got overheated yesterday simply being outdoors to long and not drinking fluids like I should have. Felt tired, dizzy and my body was not producing sweat much anymore, my husband could look at me after we got home and said sit!! drink now! and I did. Even nurses are not so smart some days, busy and forget to pay attention to the temperature gauge in the car.

These are the main things affecting your body's ability to cool itself during extremely hot weather:
- High humidity.
When the humidity is high, sweat won't evaporate as quickly, which
keeps your body from releasing heat as fast as it may need to.
- Personal factors.
Age, obesity, fever, dehydration, heart disease, mental illness, poor
circulation, sunburn, and prescription drug and alcohol use can play a
role in whether a person can cool off enough in very hot weather.
Here are some facts about which people are at greatest risk for heat-related illness and
what protective actions to take to prevent illness or death:
- People who are at highest risk are the elderly, the very young, and people with mental illness and chronic diseases
- But even young and healthy people can get sick from the heat if they participate in strenuous physical activities during hot weather.
- Air-conditioning is the number one protective factor
against heat-related illness and death. If a home is not
air-conditioned, people can reduce their risk for heat-related illness
by spending time in public facilities that are air-conditioned.
You can take these steps to prevent heat-related illnesses, injuries, and deaths during hot weather:
Stay in an air-conditioned indoor location if that is possible.
- Drink plenty of fluids.
- Wear loose, lightweight, light-colored clothing and sunscreen.
- Schedule outdoor activities carefully.
- Pace yourself.
- Take cool showers or baths to cool down.
- Check on a friend or neighbor and have someone do the same for you.
- Do not leave children in cars.
- Check the local news for health and safety updates
What happens to the body as a result of exposure to extreme heat?

People
suffer heat-related illness when the body’s temperature control system
is overloaded. The body normally cools itself by sweating. But under
some conditions, sweating just isn’t enough. In such cases, a person’s
body temperature rises rapidly. Very high body temperatures may damage
the brain or other vital organs. Several factors affect the body’s
ability to cool itself during extremely hot weather. When the humidity
is high, sweat will not evaporate as quickly, preventing the body from
releasing heat quickly. Other conditions that can limit the ability to
regulate temperature include old age, youth (age 0-4), obesity, fever,
dehydration, heart disease, mental illness, poor circulation, sunburn,
and prescription drug use and alcohol use.
Who is at greatest risk for heat-related illness?
Those
at greatest risk for heat-related illness include infants and children
up to four years of age, people 65 years of age and older, people who
are overweight, and people who are ill or on certain medications.
What is 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 sweating mechanism fails, and the body is unable to
cool down. Body temperature may 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.
What are the warning signs of a heat stroke?

Warning signs of heat stroke 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
- Confusion
- Unconsciousness
What should I do if I see someone with any of the warning signs of heat stroke?
If
you see any of these signs, you may be dealing with a life-threatening
emergency. Have someone call for immediate medical assistance while you
begin cooling the victim. Do the following:
- Get the victim to a shady area.
- Cool
the victim rapidly, using whatever methods you can. For example,
immerse the victim in a tub of cool water; place the person in a cool
shower; spray the victim with cool water from a garden hose; sponge the
person with cool water; or if the humidity is low, wrap the victim 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 victim alcohol to drink.
- Get medical assistance as soon as possible.
What is 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. Those most prone to heat exhaustion
are elderly people, those with high blood pressure, and those working or
exercising in a hot environment.
What are the warning signs of heat exhaustion?
The warning signs of heat exhaustion include the following:
- Heavy sweating
- Paleness
- Muscle cramps
- Tiredness
- Weakness
- Dizziness
- Headache
- Nausea or vomiting
- Fainting
The
skin may be cool and moist. The pulse rate will be fast and weak, and
breathing will be fast and shallow. If heat exhaustion is untreated, it
may progress to heat stroke. See medical attention if symptoms worsen or
last longer than one hour.
What steps can be taken to cool the body during heat exhaustion?
- Drink cool, nonalcoholic beverages.
- Rest.
- Take a cool shower, bath, or sponge bath.
- Seek an air-conditioned environment.
- Wear lightweight clothing.
What are heat cramps and who is affected?
Heat
cramps are muscle pains or spasms – usually in the abdomen, arms, or
legs – that may occur in association with strenuous activity. People who
sweat a lot during strenuous activity are prone to heat cramps. This
sweating depletes the body’s salt and moisture. The low salt level in
the muscles causes painful cramps. Heat cramps may also be a symptom of
heat exhaustion. If you have heart problems or are on a low-sodium diet,
seek medical attention for heat cramps.
What should I do if I have heat cramps?
If medical attention is not necessary, take the following steps:
- Stop all activity and sit quietly in a cool place.
- Drink clear juice or a sports beverage.
- Do
not return to strenuous activity for a few hours after the cramps
subside because further exertion may lead to heat exhaustion or heat
stroke.
- Seek medical attention for heat cramps if they do not subside in 1 hour.
