READING PASSAGE 1
You should spend about 20 minutes on Questions 1–13, which are based on Reading
Passage 1 below.

Chronobiology might sound a little futuristic – like something from a science
fiction novel, perhaps – but it’s actually a field of study that concerns one of the oldest
processes life on this planet has ever known: short-term rhythms of time and their effect
on flora and fauna.
This can take many forms. Marine life, for example, is influenced by tidal
patterns. Animals tend to be active or inactive depending on the position of the sun or
moon. Numerous creatures, humans included, are largely diurnal – that is, they like to
come out during the hours of sunlight. Nocturnal animals, such as bats and possums,
prefer to forage by night. A third group are known as crepuscular: they thrive in the lowlight
of dawn and dusk and remain inactive at other hours.
When it comes to humans, chronobiologists are interested in what is known as
the circadian rhythm. This is the complete cycle our bodies are naturally geared to
undergo within the passage of a twenty-four hour day. Aside from sleeping at night and
waking during the day, each cycle involves many other factors such as changes in blood
pressure and body temperature. Not everyone has an identical circadian rhythm. ‘Night
people’, for example, often describe how they find it very hard to operate during the
morning, but become alert and focused by evening. This is a benign variation within
circadian rhythms known as a chronotype.
Scientists have limited abilities to create durable modifications of
chronobiological demands. Recent therapeutic developments for humans such as
artificial light machines and melatonin administration can reset our circadian rhythms, for
example, but our bodies can tell the difference and health suffers when we breach these
natural rhythms for extended periods of time. Plants appear no more malleable in this
respect; studies demonstrate that vegetables grown in season and ripened on the tree
are far higher in essential nutrients than those grown in greenhouses and ripened by
laser.
Knowledge of chronobiological patterns can have many pragmatic implications
for our day-to-day lives. While contemporary living can sometimes appear to subjugate
biology – after all, who needs circadian rhythms when we have caffeine pills, energy
drinks, shift work and cities that never sleep? – keeping in synch with our body clock is
important.
The average urban resident, for example, rouses at the eye-blearing time of 6.04
a.m., which researchers believe to be far too early. One study found that even rising at
7.00 a.m. has deleterious effects on health unless exercise is performed for 30 minutes
afterward. The optimum moment has been whittled down to 7.22 a.m.; muscle aches,
headaches and moodiness were reported to be lowest by participants in the study who
awoke then.
Once you’re up and ready to go, what then? If you’re trying to shed some extra
pounds, dieticians are adamant: never skip breakfast. This disorients your circadian
rhythm and puts your body in starvation mode. The recommended course of action is to
follow an intense workout with a carbohydrate-rich breakfast; the other way round and
weight loss results are not as pronounced.
Morning is also great for breaking out the vitamins. Supplement absorption by the
body is not temporal-dependent, but naturopath Pam Stone notes that the extra boost at
breakfast helps us get energised for the day ahead. For improved absorption, Stone
suggests pairing supplements with a food in which they are soluble and steering clear of
caffeinated beverages. Finally, Stone warns to take care with storage; high potency is
best for absorption, and warmth and humidity are known to deplete the potency of a
supplement.
After-dinner espressos are becoming more of a tradition – we have the Italians to
thank for that – but to prepare for a good night’s sleep we are better off putting the
brakes on caffeine consumption as early as 3 p.m. With a seven hour half-life, a cup of
coffee containing 90 mg of caffeine taken at this hour could still leave 45 mg of caffeine
in your nervous system at ten o’clock that evening. It is essential that, by the time you
are ready to sleep, your body is rid of all traces.
Evenings are important for winding down before sleep; however, dietician
Geraldine Georgeou warns that an after-five carbohydrate-fast is more cultural myth
than chronobiological demand. This will deprive your body of vital energy needs.
Overloading your gut could lead to indigestion, though. Our digestive tracts do not shut
down for the night entirely, but their work slows to a crawl as our bodies prepare for
sleep. Consuming a modest snack should be entirely sufficient.
