Which of the following hormones can lead to a feeling of being cold if insufficient?

Thyroid hormone plays a critical role in regulating metabolism and influencing body temperature. It is primarily responsible for how the body utilizes energy, and when there is an insufficient level, it can significantly slow down metabolic processes. This slowdown can lead to a decreased production of heat, resulting in the sensation of feeling cold.

Individuals with low thyroid hormone levels, a condition known as hypothyroidism, often report feeling cold more frequently than those with normal levels. The hormone's impact on metabolic rate is essential for maintaining thermal regulation in the body, thus highlighting its importance in feelings of warmth and overall energy levels. Moreover, thyroid hormone influences many other bodily functions, including the development of muscles and bones, and it helps regulate the overall metabolic rate, further linking its deficiency to cold sensitivity.
