Are humans warm blooded?
Humans are warm blooded, meaning we can regulate our internal body temperature regardless of the environment. From here sweat glands and muscles are automatically triggered to ensure the body’s core temperature remains constant.
Do cold blooded humans exist?
In the modern world, humans could become cold-blooded (technically, poikilothermic) with no great problems at all. This is because we increasingly live in controlled-temperature environments.
