How Thyroid Dysfunction Can Cause Sleep Disorder

Sleep deprivation is one of the most common medical conditions in modern populations. The state may be a direct result of a degenerative disease, a mental health problem, musculoskeletal issues, or even hormone dysfunctions. Several other reasons may also be the cause of your sleep problems. There are various types of sleep disorders. However, most patients face two significant challenges:

  • Difficulty falling and staying asleep
  • Feeling sleepy all the time even following hours of rest

Role of thyroid in sleep

Can thyroid cause sleep disorder? The thyroid is a vital hormone that regulates various body functions. Synthesis and release thyroid takes place in the thyroid gland around your neck. According to studies, this hormone impacts every cell in the body, raising the basal metabolic rate (BMR). Other areas of influence include protein synthesis, digestive function, heart and brain development, bone maintenance, among many more. Thyroid dysfunction can cause sleep problems that require medical and therapeutic approaches to resolve. There are two main types of thyroid dysfunctions. Here is a look at how each can cause a sleep disorder.

Hyperthyroidism (overactive thyroid)

Hyperthyroidism is a condition that occurs when your body produces more thyroid than average. According to research, having an overactive thyroid will rapidly elevate the roles it plays in your cells. Results can include high BMRs, heating, sweating, increased heartbeat, irritability, mood swings, and restlessness, among others. The more thyroid your body produces, the more adverse these symptoms get eventually making it impossible to fall or stay asleep.

Diagnosing hyperthyroidism is challenging, primarily since the symptoms exist in several other conditions. During the initial stages, patients may feel energized and sharp. However, as it becomes more overactive, you will eventually drain your energy tanks, with the inability to fall asleep when you need to. This is very common among those suffering from insomnia.

Hypothyroidism (underactive thyroid)

Hypothyroidism is the opposite of an overactive thyroid. With this dysfunction, your body fails to produce adequate amounts of thyroid hormone. According to a study, an underactive thyroid may be the reason you feel tired all the time. It slows down processes eventually reducing your productivity. Patients of hypothyroidism find themselves needing more sleep than usual, even following several hours of sleep. Since the body processes are slow, you end up generating less energy and feeling exhausted.

Hypothyroidism symptoms include slowed heartbeat, sensitivity to cold, dry skin, constipation, and irritability, among others. The condition may also interfere with your breathing at night, causing disruptions and arousal. Patients of hypothyroidism can manage the symptoms by taking thyroid hormones such as Cytomel. Some signs exist in both hyperthyroidism and hypothyroidism. Therefore, it is recommended to consult your doctor for a thyroid test before taking OTC thyroid hormones.

Other thyroid dysfunctions

While overactive and underactive thyroids are the prevalent dysfunctions, there are different classifications. A famous example is Grave’s disease, which mostly stems from the auto-immune response. Goitre is another condition that can disrupt your sleep pattern. It is a result of inflammation and swelling in the thyroid area. Other examples are thyroid nodules (growths), Hashimoto’s disease thyroiditis, and thyroid cancer. These are merely conditions that affect how the thyroid works. Having any of these may lead to hyperthyroidism or hypothyroidism. You may also experience pain, difficulty breathing, and other symptoms that get in the way of your sleep. Since thyroid hormone interacts with all cells in the body, dysfunctions vary significantly from one subject to another.

Sleep disorders caused by thyroid dysfunction


Insomnia is a condition where patients find it difficult to fall asleep. Various factors can cause insomnia. The list includes chronic pain, sleep apnea, excessive caffeine intake, and medication. According to a study, an overactive thyroid can also lead to difficulty sleeping and maintaining sleep quality. Medical treatment is the recommendation given to insomnia patients. Complementary therapy with CBD and cannabis products can also aid muscle relaxation and relieve symptoms of hyperthyroidism. Now one can get premium-quality cannabis from online dispensary in Canada quickly right at your doorstep or your convenient location.

Obstructive Sleep Apnea (OSA)

Obstructive sleep apnea is another common sleep disorder that thyroid dysfunction may cause. Patients with this sleep disorder may experience difficulty breathing, excessive daytime sleepiness, apathy, and lethargic feelings. Those with an underactive thyroid have a higher risk of developing OSA. This may happen in various ways. Low thyroid may cause your tongue to enlarge and block airways during your sleep. It can also be a result of disrupted muscles or damaged nerves. OSA eventually leads to insomnia, especially if it continually disrupts your sleep.


Patients with any thyroid problems should seek medical attention from professional doctors in the field of endocrinology. When left untreated, you may experience a myriad of adverse side effects. Nonetheless, sleep disorders are not necessarily the result of thyroid dysfunction. You should never take any drugs before determining the root cause of your sleeping problem. The best way to go about treatment involves getting your thyroid hormone levels tested. If there is a need for thyroid hormone or complementary therapy, make sure you choose high-quality products and ingredients.
