Question

What changes would occur if a person moved from a cold swimming pool to a very warm changing room?

Answer 1

When a person moves from a cold swimming pool to a very warm changing room then the changes are :

a) During cold temperature environment skeletal muscles contract rapidly and shivering where skin hairs stand upright takes place that involve in release of heat for homeostasis. Hence vasoconstriction takes place.

But when shifted to very warm changing room sweating increases where heat is dissipated out through sweat and blood vessels become wider which allow more heat to be lost to the surroundings. Hence vasodilation takes place and people stop shivering.

This thermal regulation is regulated by thermal regulatory center present in the hypothalamus of the brain where thermoreceptors are activated based on the surroundings temperature.
