Nature took great care of man, making it possible to make up for the deficiency of nutrients from food, the environment, and water. However, people did not appreciate this gift. Pollution of air, water, production of non-natural products led to various unpleasant consequences. One of them was iodine deficiency. Why is this trace element needed? And what are the consequences of its lack?
Why does a person need iodine
Iodine is a water soluble trace element. It is found in many foods (in shrimp, seaweed). They are rich in sea air and water. In the human body, iodine is responsible for the proper functioning of the thyroid gland. Thanks to this microelement, the most important hormones are synthesized – thyroxine and triiodothyronine. They provide the correct course of metabolism, cell division, heat transfer in the body and many other functions.
If we talk about iodine, then it participates in the following functions:

Since ancient times, a person woke up with the first rays of the sun and fell asleep when it began to get dark on the street. This mode of life corresponds to the internal biological clock. By the way, circadian rhythms (changes in the intensity of biological processes in accordance with the time of day) are inherent not only to people, but also to animals and even flowers. Remember how in the morning the bud opens, and in the evening the petals begin to close. Continue reading
