PROTECTIVE MEASURES AGAINST THE EFFECTS OF HARMATTAN
Continuation (2ND AND THE LAST PART)
Climatologists describe harmattan as a hot, dry and dusty
wind that blows over West Africa.
They note that this northeasterly wind blows from the Sahara
Desert into the Gulf of Guinea between the end of November and the middle of
March. On its passage over the desert, the wind picks up fine dust and sand
particles, while the air is particularly dry and desiccating when the wind
blows over the region.
At morning, low temperatures can easily be as low as 15 °C
(59 °F) or 20 °C (68 °F). At afternoon, high temperatures easily soar to more
than 30 °C (86°F) and can reach as high as 40 °C (104 °F) sometimes, while the
relative humidity drops under 10 per cent.
In a nutshell, harmattan induces desert-like weather
conditions: it lowers the humidity, dissipates cloud cover, prevents rainfall
formation and sometimes creates big clouds of dust or sand which can even
result in violent dust-storms or sandstorms. However, when the haze effect is
weak, this dry wind creates beautiful sunny days with plenty of clear skies
Medical experts, nonetheless, insist that the dry weather
conditions, which are associated with harmattan, have various health
implications on humans, affecting their respiratory system, skin and eyes.
Dr Sopuru Chineke, a general physician at Mary’s Catholic
Hospital, Gwagwalada, says that harmattan predisposes people to upper
respiratory tract infections.
He adds that such infections could be contracted through
dust inhaled during the harmattan season.
Besides, Chineke says that people can also contract
gastroenteritis or infectious diarrhoea during the season because of scarcity
of water, saying that once there is inadequate water supply, environmental
hygiene is usually poor.
``The harmattan season is the dry season and during that
period, a lot of things happen.
``The wind is usually dusty and a lot of infections also
take place; some people end up contracting upper respiratory tract infections.

``During the season, people inhale dusty air. By the time
the dust gets into the nasal tract, the respiratory defence system tries to
treat the substances and remove the dust.
``Unfortunately, people inhaling dusty air can catch upper
respiratory tract infections, which can be transmitted from one person to
another,” he says.
Moreover, Chineke says that some people usually do not
remember to wash their hands after using the toilet; adding that when such
people use their tainted hands to prepare meals, such meals could be
contaminated.
``These are some of the ways through which infections can
spread during the harmattan season,’’ he adds.
The medical doctor, however, says that upper respiratory
tract infections can cause catarrh, nasal congestion (nasal discharge) and
cough, adding that if there is a bacterial infection, fever may also occur.
``Furthermore, the symptoms of gastrointestinal infection
include vomiting and frequent stooling as well as abdominal pain, while its
treatment depends largely on the severity of the condition,’’ he says.
Chineke explains that in event of severe gastroenteritis
infection, the infected person would be admitted in the hospital and given
fluids, so as to restore the fluids which the body system have lost due to
vomiting and stooling.
``There is also the need to treat the cause of such
infections because bacteria are usually involved. Antibiotics and other supportive therapy could be given to stop the
vomiting and stooling if the infected person is an adult,’’ he says.
Chineke, however, says that antibiotics and antipyretics are
usually used for the treatment of upper respiratory tract infections.
He says that the drugs would help to control the fever,
while efforts should be made to ensure that ``the patient does not continue to
take cold drinks or get exposed to cold’’.
He also says that consumption
of fruits and foods that are rich in Vitamins C and A will help to boost
the people’s immune system, thereby preventing infections.
Chineke, however, underscores the need to keep infected
persons in isolated areas, so as to guard against the spread of the infection
to others, particularly children.
Sharing similar sentiments, Dr Kennedy Ishaya, Gombe State’s
Commissioner for Health, advises the public to adopt precautionary measures to
prevent the occurrence of ailments associated with the harmattan season.
He lists conjunctivitis and skin problems as some of the
infections that usually occur during the harmattan season.
Ishaya urges the people to wear protective eye glasses that can prevent dust from entering
their eyes.
He, however, warns the people against bush burning in order
to ensure the preservation of trees, which are wind breakers and protectors of
the ecosystem.
Speaking on the effects of harmattan on the skin, Dr
Olanrewaju Falodun, a Senior Consultant Dermatologist at the National Hospital,
Abuja, says that human skin can become dry during harmattan season as a result
of the dry wind.
His words: ``When the skin is dry, it becomes wrinkled; the
skin can also have cracks which can degenerate into bruises and lesions.’’
Falodun says that people also have a tendency to develop
skin rashes during harmattan season, adding that the skin rashes can also
induce itching.
``When the weather is dry, a lot of itching takes place and
when people scratch the itchy skin, they may inadvertently introduce infections
to the skin,’’ he says.
He emphasizes that harmattan can also predispose people to
asthmatic attacks, sneezing and coughs.
Falodun, however, underscores the need for the people to be
well-hydrated during the period, saying: ``It
is a period when people should drink a lot of water because water helps to
hydrate the skin.’’
He also advises the people to use emollient creams which
help in moisturising the skin.
``If one has bad cracks on the skin, there is the need to
wear clothes that will cover the feet and other parts of the body prone to
dryness,’’ he says.
All the same, Falodun urges the people to refrain from
wearing clothes that can generate excessive heat during harmattan since the
season is typified by the two weather extremes.
``The harmattan period is usually characterised by heat
during the day while it gets very cold at night,” he adds.
The, the dermatologist calls on people to avoid immoderate
uses of antiseptic soaps, insisting that the use of very strong antiseptics
tends to make the skin to dry up.
Here Are
Some Notable Points Raised That Are Needed To Be Emphasized On, Or, Worked On By
All!
§ There is need for people to use protective glasses
which will help in preventing dust from entering their eyes.
§ Keeping of environment moist in other to bring down
the dust in the air, after sweeping the house and mopping, should be generally practiced
by people.
§ Bush burning should be curtailed because some of the trees
were wind breakers and protectors.
§ During the season, sicklers mostly suffer from cold
and dehydration, hence the need for prevention.
§ People need to buy to the advice of using thick clothing
kinds to protect their skin from excessive dryness; same should apply to small
children in order to protect them from any infection.
§ Avoidance of excessive uses of antiseptic soaps could
be necessary, because “the uses of very
strong antiseptics tends to make the skin to dry up” insisted the
dermatologists.
