The Link Between Overactive Thyroid and Anxiety: Understanding Sleep Troubles

Have you ever felt really anxious and found it hard to sleep? Sometimes, these issues can be caused by something called an overactive thyroid. Let’s take a closer look at what an overactive thyroid is, why it can make you feel anxious and have trouble sleeping, and what you can do about it.

What is an Overactive Thyroid?

Think of your thyroid as a little control center in your neck. It makes hormones that act like power boosts, telling your body how fast to work. An overactive thyroid, also known as hyperthyroidism, is like this control center working overtime, making too many hormones. It’s like pushing a car’s accelerator pedal too hard, making the engine run too fast.

Why Does It Cause Anxiety and Trouble Sleeping?

1. Anxiety:

When your thyroid is overactive, your body feels like it’s always in fast-forward mode. This can make you feel jittery, nervous, or anxious. It’s like being on a rollercoaster that won’t stop – your heart beats faster, and you feel on edge all the time.

2. Trouble Sleeping:

Having too much thyroid hormone can also mess with your sleep. It can make you feel too energized to fall asleep, or wake you up in the middle of the night. Imagine trying to sleep in a room that’s too bright or noisy. That’s what it’s like trying to sleep with an overactive thyroid.

Recognizing the Signs:

Apart from feeling anxious and having sleep troubles, there are other signs of an overactive thyroid. These include losing weight even if you eat the same amount, feeling hot, having sweaty skin, or a fast heartbeat. If you notice these changes, it might be time to see a doctor.

What Can You Do?

If you think your symptoms might be due to an overactive thyroid, here’s what you can do:

  • See a Doctor: A doctor can do a simple blood test to check if your thyroid is overactive. They can also help find the right treatment for you.
  • Manage Anxiety: Practice relaxation techniques like deep breathing or meditation to help calm your nerves.
  • Create a Good Sleep Environment: Make your bedroom comfortable for sleeping by keeping it cool, dark, and quiet. Also, try to have a bedtime routine to help your body wind down.
  • Healthy Lifestyle: Eating a balanced diet and getting regular exercise can also help manage symptoms.


An overactive thyroid can make you feel anxious and disrupt your sleep, but understanding this connection is the first step towards feeling better. With the right care and lifestyle changes, you can manage these symptoms and lead a more relaxed, restful life. Remember, it’s important to talk to a doctor if you’re experiencing these symptoms, so you can get the help you need.
