Benefits of Iodine

There are a lot of benefits associated with the presence of iodine in the body. From helping your body to providing the essentials for a fetus, the importance of iodine can’t be over-emphasized. The following benefits are as listed below:

Thyroid regulation: The thyroid gland is located in the front of the neck and wrapped around the windpipe. The gland plays a vital role in the growth and development of the body, metabolism, and the regulation of many functions in the body like body temperature and circulation, appetite, heart rate, blood sugar levels, cholesterol levels,  etc. The thyroid gland affects almost all organs in the body. The thyroid gland makes thyroid hormones by taking up little amounts of iodine. In the absence of iodine, there would be a decrease in thyroid hormones which leads to a condition termed hypothyroidism.

Foetus development:  During pregnancy, women will be required to consume more iodine than when they are not pregnant. Studies have shown that iodine is useful for the development of the brain of the fetus. Another study goes on to show that pregnant women who had iodine deficiency gave birth to babies that were likely to grow to exhibit lower IQ. Iodine is also useful for the overall development of a baby. It aids in producing healthy bones which in turn produces a healthy birth weight

Preventing goiter: Iodine in excess or minute amount leads to hyperthyroidism (overactive thyroid gland) or hypothyroidism (underactive thyroid gland) respectively. Either in the case of an overactive or underactive thyroid gland, the gland becomes enlarged (goiter) affecting the shape of the throat. The most common form of goiter in the world is as a result of an underactive thyroid gland.

Cognitive function for a child: The importance of iodine is as important for a fetus as it is for a child. Keeping up with a healthy brain for a child to reduce the risk of intellectual disability can be attributed to the right amount of iodine supplied through its diet.

Infection treatment: Industrialized iodine is used to treat infections and kill germs that might arise around cuts, scrapes, and breakages in the skin. It is one of the first ointments used in first aid treatment of certain injuries that have to deal with certain skin damages. However, it should not be used for deep cuts, burns, or animal bites.
