Thermal regulation is the process by which an organism maintains its internal temperature within a narrow range, despite changes in its external environment. This is crucial for animals to function properly, as many cellular processes are temperature-dependent. In mammals, for example, the hypothalamus in the brain controls thermoregulation by constantly monitoring temperature and adjusting bodily functions such as sweating, shivering, and blood vessel dilation to maintain a stable internal temperature. Research in thermal regulation focuses on understanding the mechanisms and biological processes involved in maintaining temperature homeostasis, as well as how organisms adapt to fluctuations in temperature. This research is important for understanding how environmental changes, such as climate change, may impact the ability of organisms to regulate their temperature and survive in different ecosystems.
