If you've got hypothyroidism and you're sweating like crazy, you might be scratching your head because doctors usually say hypothyroidism makes you sweat less and feel chilly. But, surprise! Sometimes folks with hypothyroidism do break out in a sweat. This might sound confusing, but keep on reading to find out the link between hypothyroidism and sweating and what you can do to overcome it.

The thyroid gland - a brief overview

The thyroid gland rests just below your Adam's apple, and although small in size, it plays a massive role in your overall health. Its main function is to produce thyroid hormones, particularly triiodothyronine (T3) and thyroxine (T4). These vital hormones impact various aspects of your metabolism, such as the way your body uses energy, produces proteins, and responds to other important hormones.


Hypothyroidism is a thyroid disorder in which the thyroid gland doesn't produce enough hormones, leading to various symptoms and an overall imbalance in bodily processes. Thyroid dysfunction, such as hypothyroidism, can impact various aspects of a person's health, making it essential to monitor and manage the symptoms through proper treatment. Some of the most common symptoms of hypothyroidism are fatigue, weight gain, and cold intolerance.

There are numerous conditions that can cause hypothyroidism, such as Hashimoto's disease, goiter (enlarged thyroid gland), surgical removal of the thyroid, and the presence of a thyroid nodule. Thyroid nodules are growths that form within the thyroid gland but are usually non-cancerous.

How does the thyroid gland control body temperature?

The thyroid gland helps control body temperature

The thyroid gland acts as the body's built-in thermostat. A well-functioning thyroid sends out hormones throughout the body to produce and maintain a stable heat level. It's one of the primary controllers in keeping our body temperature steady at around 37°C (98.6°F). 

When it's chilly, T4 and T3 thyroid hormones kick into gear, stimulating the body to generate extra heat to keep us warm. On the flip side, when it's super hot outside, and the temperature gets higher than our ideal body temperature, the thyroid takes a break from releasing hormones that warm us up. The T4 and T3 hormones that are already traveling through our bodies change a bit, so they don't make heat anymore. These hormones shed an iodine atom, turning them into inactive forms, such as T4 becoming reverse T3 (rT3).

But thyroid disorders can throw this whole temperature-balancing system off its game. In cases where your thyroid hormone levels are low (hypothyroidism), the body receives insufficient signals to create energy for heat production. As a result, people with hypothyroidism often can't tolerate the cold, meaning they feel chilled even when the outside temperature isn't low enough to justify it.

So why am I sweating excessively when I have hypothyroidism?

Hypothyroidism is not usually associated with excessive sweating. Nevertheless, there are instances where individuals with hypothyroidism might experience sweating. This could possibly be attributed to thyroid hormones playing a vital role in regulating body temperature. In scenarios where there's a lack of these hormones, the body's temperature regulation might become unstable. However, it's essential to note that there's limited scientific evidence to support this idea.

There are other, more plausible explanations for excessive sweating in individuals with hypothyroidism. One such example involves the medication prescribed for hypothyroidism, called levothyroxine. This drug is designed to replace the thyroid hormones a person's body isn't producing in sufficient quantities. However, taking more levothyroxine than necessary can lead to side effects, including sweating.

When an individual has taken an excessive dose of levothyroxine, they might experience symptoms similar to a thyroid disease called hyperthyroidism (overactive thyroid gland), such as:

  • Sweating

  • Headaches

  • Anxiety or agitation

  • A racing heartbeat

  • Difficulty sleeping

  • Nausea or vomiting

  • Diarrhea

  • Chest pain

But sometimes, hypothyroid patients take the right amount of levothyroxine and still experience sweating. Levothyroxine is the synthetic form of thyroxine (T4), the inactive form of T3. Thus, your body needs to convert it to T3 in order to use it. However, some people can't convert T4 to T3 properly, causing an imbalance in hormone levels. This imbalance may cause symptoms similar to hyperthyroidism, including excessive sweating, even if the person is not taking too much levothyroxine.

Can hypothyroidism cause night sweats?

When it comes to hypothyroidism, night sweats aren't the top symptom that comes to mind. However, this doesn't mean they can't be connected. In some instances, hypothyroidism medication, like levothyroxine, might make someone feel unusually warm throughout the day or during the night. But is there more to the story than just medications?

Menopause might be a contributing factor

Female hormones and thyroid function might share a unique relationship. Women are five to eight times more likely to have hypothyroidism than men, suggesting that there could be a link between hormones and thyroid health. For most women, the first signs of menopause appear in their mid-to-late 40s, and this shift in hormone levels – a decrease in estrogen and progesterone – can lead to hot flashes and night sweats. These hormones are believed to play a role in regulating thyroid function.

During menopause, the thyroid might have difficulty meeting the body's fluctuating hormone demands. Research has discovered a direct effect of estrogen on thyroid cells, demonstrating the connection between female hormones and thyroid function. As a result, women experiencing menopause may also simultaneously deal with thyroid-related issues.

A study conducted in 2007 focused on women with either hypothyroidism or hyperthyroidism alongside severe menopause symptoms revealed that by addressing and treating thyroid dysfunction, the participants experienced significant improvements in severe menopausal symptoms, including night sweats.

It's essential to remember that night sweats can be linked to various other medical conditions, such as anxiety, neuropathy, infections, bone marrow disorders, and specific medications. Thus, for those living with hypothyroidism and experiencing night sweats, it's crucial to consult with a healthcare professional to pinpoint the cause and develop an appropriate treatment plan.

What helps with sweating and night sweats if you have hypothyroidism?

If you have hypothyroidism and are experiencing sweating and night sweats, there are several strategies that can help alleviate these symptoms:

1. Adjust your dose

If you're experiencing sweating and night sweats due to your thyroid medication, consult your healthcare provider about adjusting your dosage. They'll likely perform blood tests, such as thyroid stimulating hormone (TSH) and T4 tests, to check your thyroid hormone level. These tests can help determine the right amount of medication for your condition, ensuring that your thyroid hormone levels are balanced and well-regulated.

2. Find the right thyroid hormone replacement therapy

If you're dealing with a thyroid condition like hypothyroidism or Hashimoto's thyroiditis, your body needs thyroid hormone replacement medication or supplements to function at its best. By providing your body with the necessary thyroid hormone, your metabolism can regulate body temperature more efficiently. Keep in mind that there isn't a universal solution when it comes to choosing thyroid medication, so it's important to work closely with your doctor to find the right fit for you.

For menopausal women, the appropriate thyroid medication might help alleviate symptoms such as night sweats and hot flashes. Plus, keeping your thyroid levels balanced can reduce the risk of complications related to both hypothyroidism and menopause.

The most common thyroid medication is levothyroxine. However, many hypothyroid patients prefer Natural Desiccated Thyroid or NDT.

Also known as desiccated thyroid extract, NDT is derived from pig thyroid glands and contains T3 and T4 hormones. NDT has been found to be effective for some people who do not respond well to levothyroxine and experience various symptoms from synthetic medication.

NDT is available in several brands, including Armour Thyroid, NP Thyroid, and ERFA Thyroid. It's also available in supplement form. One interesting option is VitaliThy, a natural desiccated thyroid you can buy online.

3. Avoid consuming triggers such as caffeine, alcohol, and smoking

Aside from addressing the thyroid problem itself, it might be a good idea to make some lifestyle changes.

Caffeine and alcohol are known triggers for increased heartbeat and sweating, especially at night. Therefore, avoiding these substances is advisable, especially in the evening. Caffeine, which is found in coffee, tea, and some soft drinks, can stimulate the central nervous system and increase body temperature, leading to night sweats.

Alcohol, on the other hand, can cause the blood vessels to dilate, leading to heat loss and subsequent sweating. Additionally, you also need to avoid spicy foods, as they may worsen your sweating.

4. Sleep in a cool, well-ventilated room

Sleeping in a cool, well-ventilated room can also help alleviate night sweats. Keep your bedroom temperature at a comfortable level and use breathable bedding to avoid overheating. Using a fan or air conditioner to circulate cool air can also be helpful. Additionally, keeping your bedroom well-ventilated by opening windows or using a dehumidifier can prevent excessive sweating.

5. Practice relaxation techniques, such as meditation or yoga, to reduce stress

Stress and anxiety activate the sympathetic nervous system, increasing heart rate and body temperature, which can trigger sweating. By practicing relaxation techniques, you can activate the parasympathetic nervous system, which helps to reduce the body's stress response, helps you to regulate body temperature, and promote a sense of calm. This can lead to a decrease in sweating and better sleep quality.

Conclusion: Hypothyroidism may sometimes lead to excessive sweating

While hypothyroidism is not commonly associated with excessive sweating, it can occur due to the thyroid gland's role in regulating body temperature. Additionally, medication prescribed for hypothyroidism, such as levothyroxine, can also cause sweating as a side effect. Night sweats may also be a symptom of hypothyroidism or a side effect of medication, but menopause could also contribute to this symptom.

To alleviate sweating and night sweats, you can adjust their medication dosage, find the right thyroid hormone replacement therapy, avoid triggers like caffeine and alcohol, sleep in a cool room, and practice relaxation techniques to reduce stress. By working with healthcare professionals to manage hypothyroidism symptoms, you can improve their quality of life.

If you're still looking for the best thyroid hormone replacement therapy for you, why not consider VitaliThy, a natural desiccated thyroid you can buy online.
