An organ shaped like a butterfly influences our state of mind, our weight, and our sleep pattern. And because the thyroid gland is so small and inconspicuous, most people do not immediately think of it if their hearts are racing, if everyday life becomes overwhelming due to fatigue, or a normal room temperature feels like a heat wave. In many cases, if we feel unwell, the cause is not old age, menopause, or depression — it is the inconspicuous thyroid gland. If it is not functioning correctly, the body’s metabolic balance is disturbed. This has serious consequences for our health and our sense of well-being. However, there are many things we can do to prevent that from happening.
