The danger of
dehydration and heat stroke:
Dehydration and heat stroke are two very common heat-related diseases that can
be life-threatening if left untreated.
What is dehydration?
Dehydration can be a serious heat-related disease, as well as being a dangerous
side-effect of diarrhoea, vomiting and fever. Children and persons over the age
of 60 are particularly susceptible to dehydration.
What causes
dehydration?
Under normal conditions, we all lose body water daily through sweat, tears,
urine and stool. In a healthy person, this water is replaced by drinking fluids
and eating foods that contain water. When a person becomes so sick with fever,
diarrhoea, or vomiting or if an individual is overexposed to the sun,
dehydration occurs. This is caused when the body loses water content and essential
body salts such as sodium, potassium, calcium bicarbonate and phosphate.
Occasionally, dehydration
can be caused by drugs, such as diuretics, which deplete body fluids and
electrolytes. Whatever the cause, dehydration should be treated as soon as
possible.
What are the symptoms
of dehydration?
The following are the most common symptoms of dehydration, although each
individual may experience symptoms differently. Symptoms may include:
In children, additional
symptoms may include:
Treatment for
dehydration:
If caught early, dehydration can often be treated at home under a physician's
guidance. In children, directions for giving food and fluids will differ
according to the cause of the dehydration, so it is important to consult your
pediatrician.
In cases of mild
dehydration, simple rehydration is recommended by drinking fluids. Many sports
drinks on the market effectively restore body fluids, electrolytes, and salt
balance.
For moderate dehydration,
intravenous fluids may be required, although if caught early enough, simple
rehydration may be effective. Cases of serious dehydration should be treated as
a medical emergency, and hospitalization, along with intravenous fluids, is
necessary. Immediate action should be taken.
How can dehydration
be prevented?
Take precautionary measures to avoid the harmful effects of dehydration,
including:
A person suffering from heat
stroke displays some classic symptoms which make identification easy; enabling
quick and appropriate medical attention to reach the person in time.
Some early symptoms that can
often be observed are:
Heat Stroke is a medical
emergency, and the most severe form of heat related illness. Anyone exhibiting
the signs and symptoms of Heat Stroke should be rushed to the nearest hospital
or clinic. Unlike other forms of heat illness, Heat Stroke does not have to be
caused by exercise or exertion. High temperatures, lack of body fluids and
overexposure to the elements can all bring about Heat Stroke. The very young
and old are especially susceptible to the hazards of this heat related illness.
What are the
symptoms of heat stroke?
The following are the most common symptoms of heat stroke, although each
individual may experience symptoms differently. Symptoms may include:
When the body overheats, it can
go into crisis. Usually we sweat when we're hot, but when someone has heat
stroke, there is no sweat, and the skin is very dry and hot. Other symptoms
include strong, fast pulse, high temperature 37ºC to 40ºC (106deg.--112deg.F), and confused, strange,
or angry behaviour. The person may feel chilled, nauseated, or dizzy, and soon
becomes unconscious.
If these are
observed then it is necessary that the patient be treated immediately to avoid
a full fledged case of heat stroke.
The
first sign to look for in a victim of Heat Stroke is red, flushed skin. People,
who are suffering Heat Stroke, do not sweat, so it is critical that they
receive emergency care immediately to relieve their body of heat.
Other
signs of Heat Stroke include:
·
A body temperature of 106-degrees or higher
·
Seizures
·
Headache
·
Rapid pulse
·
Unconsciousness
How is heat stroke
treated?
It is important for the person to be treated immediately as heat stroke can
cause permanent damage or death. There are some immediate first aid measures
you can take while waiting for help to arrive.
Intravenous fluids are
often necessary to compensate for fluid or electrolyte loss. Bed rest is
generally advised and body temperature may fluctuate abnormally for weeks after
heat stroke
How can heat stroke
be prevented?
There are precautions that can help protect you against the adverse effects of
heat stroke. These include:
Prevention of Heat
Stroke
It is possible to avoid
suffering the ill effects of heat related disorders by taking a few simple
precautions. Apart from the
above, a person suffering from heat stroke will display the following symptoms:
At times it has been reported
that colleagues who are unaware of heat stroke and its symptoms may think that
the victim is upset, intoxicated or just "acting strangely" and fail
to call for help. This can have devastating consequences on the victim, as it
is vital that proper care reach him in time.
Even if proper care is taken many
people still run the risk of suffering from heat stroke. In case someone near
you suffers from a heat stroke then the following are some first aid steps that
can be implemented until medical help arrives.
Prevention is better than cure.
This holds true for heat stroke and every individual can take certain
precautions to ensure that they are protected from the adverse effects of heat
stroke.
The following are a few basic
measures which can be followed:
* If you have a chronic medical
problem please tell your affinity group about it. *
Before going to the protest,
consult your doctor about whether any of the medications you are currently
taking will put you at greater risk. If so, think about filling a different
role than front line protestor. There are lots of important places for support
people, contact the welcome centre for more details.
If you do need medication, MAKE
SURE IT HAS YOUR NAME ON IT. The Kops are very suspicious of anything they
cannot quickly identify. If you do get arrested and want to keep receiving your
medication, you must indicate what the medication is as well as who and what
it’s for. Let the medical monitor in your affinity group know that you are
currently taking medication and be very specific as to how often you need to
receive it and where they can find it in the case of an emergency. This applies to everyone taking any
form of medication.
These are some measures that can
be taken to ensure your safety and the safety of your group. However if a
person is experiencing heat stroke they must get immediate medical attention
because it is an emergency.
When it comes to heat, your body is like a car. If either one overheats, it can cause minor or major problems. But knowing what to do can help your body (or your car for that matter) to keep running. When a person has heat stroke, it's like a car running with almost all the water boiled out of the radiator. It's very serious, and can lead suddenly and without warning to a complete breakdown.
As you move, your body heats up. Your body keeps cool by sending blood close to your skin, and by sweating. When the temperature is above 25ºC, when the humidity is high, or when the sun is beating down on your head, it's difficult to stay cool. When they are in extreme heat, people can suffer heat cramps and exhaustion. These are unpleasant and can be somewhat serious. But, if they suffer heat stroke, they run the risk of brain damage and even death.
For more info contact,
1. Contact a medic or ambulance personnel (E.M.T.) right away. If the person has stopped breathing, use artificial respiration to get breathing going again.
2. Move the victim to a cooler area, and if possible, soak the person in a cool bath. Use a fan or cold packs if available. Keep the victim lying down with feet raised.
If you know you'll be exposed to greater heat or humidity than normal, take several days to get used to it by spending time in similar conditions. Take frequent breaks and drink plenty of cool water. Even when you're not thirsty, your body is losing fluid that needs to be replaced. Alcohol makes it harder for your body to keep cool, so avoid alcohol when you do hard work in hot weather.
Know the difference
It’s
important to note the differences between the three main heat related illnesses.
While heat cramps can be uncomfortable, they are not life threatening. Heat
stroke, on the other hand, needs immediate medical attention.
Heat Cramps
Heat cramps are caused by
muscle contractions in both the gastronomies or hamstring area (back of calves).
Feeling most like a severe muscle pull, heat cramps are forceful and painful.
Heat cramps are associated with lack of fluids, high temperatures and lack of
physical conditioning. Heat cramps, while painful, are not life threatening.
Ignoring heat cramps however, can bring about the progression of other, more
serious heat related illnesses. Heat cramps can be treated with water, cool air
and rest.
Heat Exhaustion
This condition is exactly
what it sounds like: severe exhaustion caused by extreme body heat. Excessive
heat and dehydration can cause the body to overreact, thus raising your body
temperature to over 102-degrees. Symptoms of Heat Exhaustion include paleness,
nausea, extreme fatigue, dizziness, light-headedness, and vomiting, fainting
and cool, clammy skin. Heat Exhaustion is a serious illness and should be
carefully monitored. Cool, shady environments, liquids, cool rags placed on
various areas of the body and replacement of electrolytes (such as those found
in sports drinks) are used to treat this condition. If body temperature remains
elevated even after treatment, it's best to consult your doctor for further
information and instruction.
Hydration
The easiest way to avoid
Heat Stroke and other heat disorders is to keep your body well hydrated. This
means drinking plenty of water before, during and after exposure to the
elements. Sports drinks are a good choice if you’re exercising or working in
hot conditions, but water works fine, too.
Staying in a place where
there is plenty of airspace which will help allow your body to naturally cool
itself. Sitting in a shaded, wide-open area will help your body rid itself of
heat through sweating. If you're indoors, always-open windows, use a fan,
central air or air conditioning during excessively hot days.
Clothing
What you wear can play a
big factor in how your body will handle the heat. Light coloured, loose fitting
clothing will aid your body in breathing and cooling itself down naturally.
Tight clothing restricts such a process and dark colours absorb the sun’s light
and heat. It’s okay to wear a hat to shield yourself from the sun, but once you
feel yourself getting warm, it’s best to remove any items that are covering your
head. Continuing to wear head garments will only keep more heat trapped inside
of your body.
Limit Yourself
Watching how much
activity you’re participating in during hot days is also important. Don’t
overdue it. Heat Stroke can begin in less than an hour. If you feel yourself
getting warm or light-headed, it’s best to take a time out from the demo and
rest in the shade.
Heat related illnesses
are preventable. Like many sicknesses, it's easier to take steps against Heat
Stroke than it is to treat it. Most medics recommend consuming eight or more
glasses of water a day during normal weather conditions and twice that during
high heat periods.
