Fact #2: It’s like a mini factory

The thyroid gland is like a special factory! The cells inside your thyroid make chemicals called hormones.

Thyroid hormones act like messengers that tell your body how to use energy from food. They help your body burn energy so you can grow big and strong.

Here are some more fun facts about thyroid hormones:

  • They make your heartbeat speed up.
  • They make you breathe faster and take in more oxygen
  • They activate bone growth in kids.

Iodine is a mineral found in seaweed. It’s also in other foods like fish, milk, and eggs.

When you eat food containing iodine, your body absorbs it and sends it to your thyroid gland.

Then, your thyroid gland uses iodine to make thyroid hormones.

Fact #4: It affects how you feel

The hormones from your thyroid gland can affect your emotions and energy level.

These thyroid facts are not so fun:

  • You could feel jittery and anxious if your thyroid gland makes too much hormone.
  • You could feel sad and sluggish if your thyroid gland does not make enough hormones.

Fact #5: You can live without your thyroid

It’s true: life can go on without a thyroid.

Sometimes, the thyroid gland can get sick. When that happens, it doesn’t work properly.

  • If it doesn’t make enough hormones, you might feel tired and have trouble growing. Your skin might feel dry, cold, and rough.
  • If the thyroid makes too many hormones, you might feel hyper and have trouble falling asleep.

But try not to worry. If there’s a problem with the thyroid, doctors can fix it with medicine or surgery. So, listening to your body and seeing your doctor if you feel sick is important.
