Prepare
Your Self
The sun brings
happiness. It can brighten up the worst days. Wherever in the
world you live, no matter in what civilization or era, no
matter what your views on life and health, you would probably
find the sun a common feature in people’s thoughts.
Summer heat waves can be dangerous. A beautiful, sunny day can
be fun and exciting but if one is not careful it can also
bring life threatening illnesses. The heat can overwhelm the
body’s ability to regulate internal body temperature. Risk of
heat-related illnesses is present when the temperature hits
90°F and above and there is considerable humidity (60 percent
and above).
In such environments, risk of heat stroke, cramps and
exhaustion is high if physical activities are pursued or
exposure to the elements is prolonged. Heat sickness is fast
acting and dangerous. In some cases, it can induce coma and
even lead to death. Heat cramps are not dangerous but heat
strokes can be life threatening. It is fatal 50 percent of the
time and requires urgent medical care.
People at risk of heat-related illnesses are the elderly (65
and above) and weak with low levels of fluid in their bodies.
Overweight people and those with heart, kidney, lung problems
or high blood pressure are also at risk. People on
anticholinergics (sweat blocking medicine), beta-blockers
(reduces blood circulation to the skin), tranquillizers,
antibiotics and birth-control pills are also at risk.
Infants and children under 4, pregnant women (particularly if
their fluid/salt levels are low), people under the influence
of alcohol, and outdoorsy people who do not take sensible
precautions (such as drinking water) to guard against heat
illnesses are also at risk. Urban populations are at a higher
risk because concrete and asphalt retain and give off heat.
Whether or not you fall into any of the aforementioned
categories, good judgment dictates that simple, sensible
precautions be exercised to avoid potentially fatal
consequences of heat-related illnesses. This article is
intended to clue people in as to how best to protect
themselves.
The body cools itself by sweating. Under some conditions,
sweating is not enough and very high temperatures may damage
the brain or other vital organs. All activity should be
undertaken in order to aid the body’s cooling mechanisms.
Heat Cramps:
Forceful and painful muscle contractions in the gastronomies
or hamstring areas (back of calves) are a symptom of heat
cramps. Most of the time, it will feel as if a muscle has been
severely pulled. This is due to the loss and lack of
electrolytes in the body, usually lost by way of sweating.
Cramping can begin in the arms, legs or abdomen and may be a
precursor to heat exhaustion. Though not life threatening, if
not treated these can lead to complications.
Treating such cramps is simple. Stop all activity and rest.
Exposure to the sun must be avoided and the body placed in a
cool environment. Loose clothing is recommended. The person
must be sprayed with water and parked near a fan. Muscle areas
should be gently massaged to relieve spasms. Cold compresses
on the head, neck, armpits and the groin area may be
necessary. Medication must not be administered to lower the
fever. It is recommended that the patient be given slightly
slated water every 15 minutes. Alcohol and caffeine must be
avoided.
Heat Exhaustion:
A serious illness, heat exhaustion should be carefully
monitored. The exhaustion is the body’s response to an
excessive loss of water and salt through sweat. It occurs when
physical exhaustion (from strenuous exercise) together,
dehydration and extremities in the weather cause the body to
overreact.
The body temperature can rise to over 102°F causing pallor,
dizziness, nausea, and profuse sweating. Vomiting and fainting
spells can also occur in more severe cases. It is recommended
that rest be sought in a cool, shaded environment and lots of
fluids be taken. In other cases, fluids may have to be
administered intravenously to replace electrolytes. Placing
wet towels on the body can provide temporary relief. Since
this can lead to heat stroke, medical advice must be sought.
Heat Stroke:
If not diagnosed and treated immediately heat exhaustion can
lead to all out heat stroke, also known as sun stroke. This is
the worst heat-related malady in which the body becomes
overheated in a relatively short span of time. This can be a
life-threatening condition and requires urgent medical
attention. It occurs during hot, humid weather when the body
cannot dispose of excess heat in the normal way as the brain
loses its ability to regulate temperature.
The patient will be hot, flush and warm to the touch.
Temperature will be markedly high and there will be little
perspiration. A person with heat stroke who has been
exercising may still be sweating, but in both cases, the
person will have an elevated body temperature, greater than
41°C. Heat stroke can also cause nausea, loss of appetite,
muscular twitching, dilated pupils, dry mouth, confusion,
headaches, shallow and weak breathing, disorientation,
aggression and even unconsciousness.
If the temperature rises above 41°C, things can get
complicated. High blood pressure, heart failure, brain
swelling, convulsions, kidney or liver failure, coma and even
death can occur. Patients must be cooled as quickly as
possible. Loose clothing and cold compresses are recommended.
Cold compresses must be applied to the head, neck, armpits,
groin, wrists, ankles and knees to cool the larger blood
vessels.
An effective way to cool the patient is by wrapping him or her
in a wet sheet and then fanning these sheets to drop
temperatures through evaporation. Comfort levels of the
patient must be monitored. In case the patient shivers, the
fanning process must be slowed. Do not place the patient
directly in front of an air conditioner or some such cooling
device because this will cause vessels to contract.
If you fear you have any of the aforementioned symptoms, seek
medical assistance immediately. Again, do not take medication
to lower the fever. It will not be effective and may actually
worsen the situation. Do not feed the patient orally (even
water) until the condition stabilizes.
(Never give patients stimulants or hot drinks as treatment.)
These self-help measures are no substitute for proper medical
attention. Prevention is the best remedy and early warning
signs must be heeded.
Save Yourself:
It is possible
to avoid suffering the ill effects of heat related disorders
by taking a few simple precautions. The easiest way to avoid
heat stroke and other related disorders is to keep your body
well hydrated. During hot weather, you will need to drink more
liquids than your thirst indicates. This is especially true if
you are over 65 years of age. Avoid very cold beverages to
prevent stomach cramps or drinks containing alcohol, which
will cause you to lose more fluid. Drink plenty of salty
liquids (at least 3 to 5 litres a day) and fruit juices to
replace salt and minerals.
Some people perspire more than others. And these people must
gulp down fluids. If physical exertion is impossible to avoid,
ensure that you take in more salt than usual with meals. This
will help you retain water and ward off dehydration. If you
are on a low-salt diet, ask your medical professional on what
you may drink or eat. Wear light, ventilated and loose clothes
that will allow your body to breathe and cool itself
naturally.
Tight clothing restricts blood circulation and dark colours
absorb sunrays and heat. Woven materials are best to absorb
harmful ultraviolet (UV) rays. Sheer clothing or wet clothing
does not block UV rays. It is recommended you wear a hat when
out in the sun. If you feel hot, remove the hat or any other
item covering your head. Headgear prevents heat from escaping.
When temperatures hit 90 or higher, a fan will not prevent
heat-related illnesses. A cool shower or bath is the way to
go. When going outdoors use sun block lotion.
If you do not have air conditioner in your home, consider
spending time in a mall or a public library or any other
air-conditioned location. While indoors, use the fan and open
windows. Plan outdoor activities for before noon or in the
evening. When outdoors, step into the shade every now and
then. Do not leave infants, children or pets in a parked car.
Cars with windows closed become trap in heat. Protect your
pets by bringing them indoors. All children and infants must
also be dressed in loose clothing and shade them with a hat or
an umbrella. Do not bundle babies in blankets or heavy
clothing. Infants do not have developed sweat glands and they
cannot suffer heat as well as adults can. Ensure that all
children and infants get an adequate amount of water to drink.
Animals must also be given plenty of fresh water and hosed
down.
Heavy foods and meals must be avoided because they heat up the
body. Carry a bottle of boiled water. Summer is the season of
viral and bacterial infections that can spread through water
and food resulting in cholera, gastroenteritis, jaundice and
typhoid. Avoid drinks from the markets like “fresh-pressed”
juices and shun roadside foods. Water from shallow ground
wells may also be infected. Roadside drinks must be avoided
since they are highly susceptible to contamination. Boiled
water and fizzy bottled drinks are the best way to go.
Chugging saltwater with lemon is one of the best ways to
prevent disease and infection.
