Change in heart rate and trouble learning and remembering

Your heart rate is the number of times your heart beats each minute. It might be influenced by your iodine levels. A lack of this mineral may cause your heart to beat slower than normal, while a surplus may cause your heart to beat faster than usual. An abnormally slow heart rate might result from an acute iodine shortage. This might make you feel weak, tired, dizzy, and perhaps faint.

A lack of iodine may impair your capacity to learn and recall. A study of over 1,000 people indicated that those with greater thyroid hormone levels outperformed those with lower thyroid hormone levels on learning and memory tasks. Thyroid hormones aid in the growth and development of your brain. That is why a lack of iodine, which is essential for the production of thyroid hormones, might impair brain development. In fact, studies have discovered that those with low thyroid hormone levels have a smaller hippocampus, the portion of the brain that governs long-term memory.
