在脊椎动物中,哺乳类动物和鸟类动物体温恒定,大约在37℃左右。保持体温,减少对环境的依赖性,增强对环境的适应能力。例如狗、猫、鸽子、鹦鹉等。注意:不是所有哺乳动物都恒温,例如刺猬。刺猬是哺乳动物,但不恒温。
若人体与环境达成热平衡,以保持体温恒定,就谓之具有热舒适性。
Thermal comfort exists if the human body in thermal equilibrium with its environment, implying a constant temperature of the body.
恒温动物是指诸如现代鸟类和哺乳动物这种可以保持体温恒定的动物。
Endotherms are animals such as modern birds and mammals that keep their body temperatures constant.
但生活在深海中的无脊椎动物就就无需调整体温,可以保持体温恒定。
Furthermore many invertebrates live in the depth of the ocean never experience a change in the chill of deep water, their body temperatures remain constant.
