Insulation (fat retains heat and hairs trap warm air) & vasoconstriction (arterioles constrict to move blood away from the skin) are methods to keep warm. Shivering also generates heat through muscle activity.
La aislamiento (grasa que retiene el calor y pelos que atrapan aire caliente) y la vasoconstricción (arteriolas que se contraen para alejar la sangre de la piel) son métodos para mantener el calor. El temblor también genera calor a través de la actividad muscular.
