What are heat intolerances associated with thyroid disorders and the impact on exercise?
Heat Intolerances and Thyroid Disorders
Thyroid disorders, such as hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), can affect the body's ability to regulate temperature, leading to heat intolerance.
Hypothyroidism
In hypothyroidism, the body's metabolic rate is slowed down, which can make it more difficult to dissipate heat. This can lead to heat intolerance, especially in warm or humid environments. Symptoms of heat intolerance in hypothyroidism may include:
* Feeling overheated and sweaty, even in mild temperatures
* Difficulty cooling down after exercise or other activities
* Feeling tired or weak in hot weather
* Headaches or dizziness in hot weather
* Difficulty concentrating in hot weather
Hyperthyroidism
In hyperthyroidism, the body's metabolic rate is increased, which can also lead to heat intolerance. However, heat intolerance in hyperthyroidism is often less common than in hypothyroidism. Symptoms of heat intolerance in hyperthyroidism may include:
* Feeling overheated and sweaty, even in mild temperatures
* Difficulty cooling down after exercise or other activities
* Feeling tired or weak in hot weather
* Headaches or dizziness in hot weather
* Difficulty sleeping in hot weather
* Increased thirst
* Weight loss
Impact on Exercise
Heat intolerance can have a significant impact on exercise performance. In hot or humid weather, people with thyroid disorders may find it more difficult to exercise at their usual intensity and duration. They may also experience more fatigue, muscle cramps, and heat-related illnesses, such as heat exhaustion or heat stroke.
Tips for Exercising with Thyroid Disorders in Hot Weather
If you have a thyroid disorder and you experience heat intolerance, there are several tips you can follow to help you stay safe and comfortable while exercising in hot weather:
* Exercise in the early morning or evening when the temperatures are cooler.
* Choose shady spots for your workouts.
* Wear loose, lightweight clothing that will help you stay cool and dry.
* Drink plenty of fluids before, during, and after your workout.
* Listen to your body and take breaks if you feel overheated or tired.
* Avoid exercising outdoors on days when the heat index is above 90 degrees Fahrenheit.
Talk to your doctor
If you have a thyroid disorder and you are concerned about exercising in hot weather, talk to your doctor. They can give you personalized advice on how to stay safe and comfortable while exercising.
