Question 1 Evaporation is an important mechanism for
eliminating heat, particularly on a hot day or when exercising.
What are some of the negative consequences of this mechanism
of heat loss? [5]
Evaporation plays a critical role in thermoregulation by allowing
the body to dissipate excess heat through the evaporation of
sweat. However, this mechanism of heat loss has several
negative consequences, particularly in extreme conditions or
when the body’s ability to regulate temperature is compromised.
Below are some of the key negative consequences:
1. Dehydration
Excessive sweating leads to significant fluid loss, which
can result in dehydration if fluids are not replenished.
Dehydration can cause dizziness, weakness, confusion, and
in severe cases, heat exhaustion or heatstroke.
The loss of essential electrolytes (such as sodium,
potassium, and chloride) can lead to muscle cramps,
fatigue, and impaired nerve function.
2. Electrolyte Imbalance
Sweating removes vital electrolytes from the body, leading
to an imbalance that can disrupt cellular functions.
