The Thyroid Gland may be compared to the carburettor of an engine that provides the necessary fuel and oxygen to make the vehicle run. The Thyroid gland’s primary function is to regulate the speed at which your body works which is called metabolism, the system that governs the rate of energy expenditure in the body.

The pituitary gland, situated at the base of the brain as a compact mass of cells, performs a role akin to that of an accelerator pedal in a vehicle, overseeing and regulating the functioning of the thyroid gland.

The thyroid gland utilizes two hormones, namely T3 and T4, which are circulated through the bloodstream to communicate with all tissues and cells, thereby influencing vital bodily functions such as heart rate, energy levels, digestion, temperature regulation, and even your thoughts and feelings.

Effectively if the levels of the T4 hormone are too low the cells work too slowly and if it is too high the cells work much too fast.

The Brain constantly measures these hormone levels and if they a too low the pituitary gland issues a thyroid stimulant hormone TSH, to get the thyroid gland to improve T4 hormone secretion.

While the human body operates as a fully integrated system, the thyroid system can occasionally malfunction, especially as we get older. To gain a comprehensive understanding of one’s overall well-being and how to maintain good health, reading “The Healthiest Human” is undoubtedly a valuable investment. This book delves into every single facet of health and wellness.
