Surviving the
Heatwave
It’s becoming a norm these
days for European countries to be experiencing bouts of heatwave during the
summer season. Heatwave has serious health implications, such as sunburn, skin
cancer, heat cramps and heat exhaustion, and in more severe cases such as heat
stroke, it can prove to be fatal if not treated properly and immediately. With
temperatures soaring to as high as 36 degrees celcius – even hotter than some
parts of Asia – it is therefore important to ensure that you take all necessary
precautions before heading for Europe this summer, particularly worst-hit
countries like Spain, Germany, Greece, Italy, France and London.
How heat affects the body
Humans naturally dissipate
excessive heat from their body by perspiration. But sweating alone does not help
cool the body, unless the sweat is quickly evaporated. High levels of humidity
which is often associated with heatwave hinders the process of evaporation.
When heat gained by the body
exceeds the amount of heat the body dissipates, and when the salt & water lost
through perspiration is not quickly replaced, this would cause a chemical
imbalance in the body as the body’s temperature rises and the body continues to
lose more water and salt, leading in heat-related symptoms.
Preventative measures in the
event of a heatwave
Don’t wait until it’s too
late – prevention is still better than cure. It is best to follow the steps as
outlined below to avoid developing symptoms associated to heatwave.
Slap on lots of sunscreen
Apply some sunscreen all over
your body before going out into the sun. Use a high SPF no lower than 30. If you
sweat excessively while wearing it, make sure that you keep reapplying the
sunscreen once every hour or more. This could prevent you from getting sunburn,
and thus developing skin cancer in the long run. 
Drink plenty of plain water
Carry a 2-litre bottle of
plain water, preferably mineral water, with you at all times, to replenish the
fluid lost through sweating. Sip from the bottle regularly from time to time.
Refrain from taking diuretics such as caffeinated drinks (cola, coffee & tea)
which help disperse liquid from your body faster, as well as carbonated drinks.
Avoid alcohol at all costs.
Wash often
Sweaty and oily skin is the
perfect breeding ground for bacteria, leading to all kinds of skin problems.
However, more than just for hygienic purposes, dousing yourself in cold water
every now and then helps to reduce body temperature and cool down the body. Do
not take hot baths as this helps evaporate moisture from your body faster.
Wear appropriate clothing
Wear something cool and light
on your body. Cotton is best as it provides good ventilation as well as absorbs
sweat effectively. Wear white or light colours and refrain from wearing black as
it absorbs the heat faster. Shield your eyes from the sun’s harmful rays with
UV-protective sunglasses. Wear a large, wide-brimmed hat on your head or carry a
large umbrella with you – you may look silly, but it’s better to be silly than
sorry. Wear comfortable, breathable shoes – preferably open-toe sandals – to
minimize the chances of getting painful blisters and chafing on your feet as you
walk around in the hot weather.
Carry the barest minimum
Make sure you only carry what
is absolutely necessary on you when you walk around town in the hot sun.
Carrying excessive load such as a huge backpack only makes you sweat more and
exhausts you faster. Just bring passport, money, keys, sunscreen, mineral water,
travelcards and some medications, plus a few essentials.
Avoid peak travel times
In most large cities in
Europe, the entire transport network, especially the subway, is at its busiest
during peak hours, which is generally from 12 noon to 2 o’clock in the
afternoon, and all day during the weekends, especially on Saturday. Some of them
have no proper ventilation and air-conditioning system to cope with the extreme
heat during summer, so it can be very hot and stifling inside which further
increase the risk of heat exhaustion and dehydration. Avoid travelling during
peak hours – if you can’t avoid it, try not to take the public transportation.
Eat well
Stock up on a lot of
carbohydrates, such as pasta, bread, rice and potatoes, to help you sustain your
energy during the hot days. Taking these food constantly in moderate amounts
could help boost your energy levels and help your body to function better in
such conditions. Decrease your intake of protein such as meat and nuts as it
increases your metabolic rate, thus resulting in the production of more heat
within your body.
Get plenty of rest.
Do not literally exhaust
yourself to death. Get adequate rest in-between travels, and get a good night’s
sleep at the end of it. A tired and sleep-deprived body only increases your
chances of suffering from heat exhaustion, especially since European daylight
time is often much longer during summer, especially up north where it can last
up to 18 hours.
Bear in mind that those who
are most vulnerable to heat-related symptoms are children, elderly people, those
on medications and those with weight and alcohol problems, so be extra vigilant
and prudent when travelling in the company of such people.
In the event of more serious
symptoms such as severe heat exhaustion and heat stroke, do not panic. Carry the
afflicted person to a cooler place and try to further bring down the body
temperature by cold-water sponging and fanning. Do not give them water under any
circumstance – this could prove to be lethal. Call for medical help immediately
– do not delay any longer than what is necessary.
