, 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]
Question 1: Negative Consequences of
Evaporative Heat Loss
Evaporation is a crucial mechanism for regulating
body temperature, especially in hot environments or
during physical activity. However, excessive
reliance on evaporative cooling can have several
negative consequences:
1. Dehydration – When sweat evaporates, it
removes heat but also leads to fluid loss.
Excessive sweating without adequate fluid
replacement can result in dehydration, causing
symptoms such as dizziness, fatigue, dry mouth,
and decreased urine output.
2. Electrolyte Imbalance – Sweating not only
removes water but also essential electrolytes like
sodium, potassium, and chloride. A significant
loss of these minerals can lead to muscle
cramps, weakness, confusion, and in severe
