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 crucial role in thermoregulation by helping
to dissipate excess heat from the body, particularly through
sweating. However, there are several negative consequences
associated with this mechanism of heat loss. Below are some of
the key drawbacks:
1. Dehydration
Excessive sweating leads to the loss of water and essential
electrolytes (sodium, potassium, chloride).
If not replenished, dehydration can cause fatigue, dizziness,
confusion, and heat exhaustion.
2. Electrolyte Imbalance
Sweating depletes vital minerals necessary for muscle
function and nerve signaling.
This can lead to muscle cramps, weakness, irregular
heartbeats, and, in severe cases, heat stroke.
3. Reduced Blood Volume and Circulatory Strain
Fluid loss from sweating decreases blood plasma volume.
