Yes, Humans are warm-blooded
The ability of an organism to regulate its internal body temperature independently of the environment is called homeotherms. They have a very narrow range of temperature fluctuation and are also called warm-blooded animals. All mammals and birds are warm-blooded animals.
They have the ability to regulate the internal body temperature, thus warm-blooded or homeothermic organisms. The internal human body temperature ranges between 36.1oC to 37.20C (97°F to 99°F). Any fluctuations beyond this range can be fatal.
Warm-blooded birds maintain a constant body temperature that does not change in response to changes in the ambient temperature. Birds use a range of metabolic processes that generate or release heat to maintain a constant body temperature. The feathers of the birds protect them from the heat and cold.
Animals cannot adjust their internal body temperature to the changing surroundings. They typically struggle to thrive in high-temperature environments. Reptiles and fish are two examples. This holds true for all animals, including worms, fish, amphibians, and reptiles, except mammals and birds. When an animal has a body temperature that is virtually identical to its environment, it is said to have "cold blood." The body temperature of a fish swimming in water that is 40°F will be pretty close to that temperature. The identical fish will have a body temperature of about 60° F in water that is 60° F.
