Water’s high specific heat capacity plays a vital role in maintaining stable body temperature in many organisms, including humans. It prevents sudden fluctuations in body temperature by absorbing excessive heat during physical activity or exposure to high temperatures. When the surrounding temperature is low, the stored heat in the body helps keep it warm.

An intriguing discovery related to water’s specific heat capacity was made by German physician and scientist Julius Robert Mayer in 1819. While treating patients with fever, Mayer observed that their body temperature would rise significantly without a proportional increase in the temperature of their surroundings. This observation led Mayer to conduct further research on heat and its interaction with water, ultimately contributing to our understanding of water’s unique thermal properties. Mayer’s groundbreaking work laid the foundation for subsequent investigations on water and its critical role in supporting life.
