Peripheral Circulatory and Metabolic Consequences of Thyrotoxicosis: V. Thermoregulation in Thyrotoxicosis in the Basal State and at Elevated Environmental Temperature

Abstract

Features of the thermoregulation have been studied in normal and thyrotoxic individuals at room temperature of 26°C and 35°C. It was found that thyrotoxicosis of moderate degree represents a considerable stress on the thermoregulation, particularly on the blood circulation. Thyrotoxic subjects show signs of being well adapted to the demand for increased dissipation of heat, but their thermoregulation was not sufficiently effective to prevent rectal temperature from rising after one hour's exposure to 35°C.

Key Words:

• Thyrotoxicosis
• blood flow
• oxygen consumption
• body temperature regulation
