Hey there! I have attached the sample answer provided by NESA in the spoiler below

Question 29 (b)
Sample answer:
The human body produces a lot of heat during exercise, and loses this heat mainly through
the evaporation of sweat from the skin. Evaporation is the process of converting liquid to gas.
On hot and humid days, temperature control becomes more difficult – it is more difficult to cool
the body by evaporation because the air is already saturated with water, which reduces the
body’s capacity for evaporation.
The heat produced in the body during exercise must be lost or serious problems can occur.
When the body’s core temperature moves outside of an acceptable range, the body’s capacity
to perform will be reduced. Athletes are commonly affected by heat or cold illness. If not
managed promptly and appropriately, these illnesses can become serious.

In cooler climates, heat loss is not usually a problem; however, if it is very cold, the body may
not produce enough heat to keep the core temperature within an acceptable range.
Airflow across the body results in heat loss by convection. Cold, windy conditions increase heat
loss by convection. Athletes should be aware of the increased potential for heat loss by this method
when exercising in these conditions. Clothing also influences heat transfer by convection.
Heat can radiate from a warm object to a cooler one. In a cold climate, an athlete will radiate
heat to the environment surrounding them. During exercise on a warm day, an athlete will absorb
heat from the surrounding environment.
Heat is also transferred when two objects of different temperatures contact each other; for
example an athlete will lose heat to the environment on a cold morning. Conduction is
particularly important when exercising in water. Water is an effective conductor of heat;
therefore, body heat will be lost very quickly in cool water.
If athletes are training in hot conditions, or travelling to a hot climate, they should allow for a
seven to 10-day acclimatisation period, which is needed for the body temperature regulation
system to adapt to the hotter conditions. Fluid replacement is very important when exercising in
hot conditions. Once acclimatised, a fitter person will sweat sooner and more, and lose less salt
in sweating than a less fit person. The fluid lost must be regularly replaced to allow the cooling
process to continue.
Wearing appropriate clothing is another important strategy athletes can use when exercising in
hot and humid conditions. Athletes should try to wear a minimal amount of light-coloured and
loose-fitting clothing, which also allows for adequate ventilation in order for sufficient
evaporation to occur.
Additional strategies that an athlete may utilise in order to allow cooling to occur during
competition and training are:
• exposing as much of the body surface as possible during breaks in play
• putting ice in the armpits, neck and groin during breaks in play
• using fans and shade during breaks in play.
Having longer breaks in play and shorter periods of play during extremes in temperature may
assist. Introducing more drink carriers in particularly hot and humid conditions, or utilising ice
jackets where available, can help.

So basically in your climatic conditions syllabus notes maybe include 2-3 ways to reduce the ill-effects of the things listed and use those for a question like that

Oh i know where they're coming from now, thanks.
Just a book i have that suggests an answer that's really not close to the syllabus and was confused.
