Adaptation to a Cold Environment

Acute adaptation to a cold environment involves decreased heat loss by vasoconstriction of the cutaneous vascular bed and inhibition of sweating even during exercise. Shivering and increased muscular activity increase heat production, and generally heat balance can be maintained even by the nude body at temperatures as low as 0 to 4.5°C (32° to 40°F). As discussed earlier, individuals who have adapted to a cold climate over long periods also exhibit a limited ability to increase chemical thermogenesis by elevated catecholamine and thyroxin levels (particularly T3, but also T4; see Chapter 39), but the resulting stimulation of the thyroid gland leads to a greater incidence of goiters in populations in cold
