Shivering
D
Increased metabolic rate
Verified step by step guidance
1
Identify the body's normal cooling mechanisms. The body has several ways to regulate temperature, including sweating, vasoconstriction, shivering, and changes in metabolic rate.
Understand the role of sweating in thermoregulation. Sweating is a process where sweat glands produce moisture on the skin surface, which evaporates and helps cool the body.
Differentiate between cooling and warming mechanisms. Vasoconstriction, shivering, and increased metabolic rate are typically associated with warming the body, not cooling it.
Recognize that sweating is a primary cooling mechanism. It is the body's natural response to overheating, helping to dissipate excess heat through evaporation.
Conclude that among the options provided, sweating is the correct answer as it directly contributes to cooling the body by facilitating heat loss through evaporation.
