Hashimoto’s and exercise

It’s been long known that regular physical activity is important for virtually every person in order to maintain a healthy body and mind.

Physical activity reduces the risk of cardiovascular diseases, certain cancers, diabetes type 2, depression, and bone and joint diseases (1).

In case of people suffering from Hashimoto’s, certain modifications or restrictions to exercise routines should be incorporated, in order to accommodate the specific needs of each person and the unique demands of the disease. But physical activity is still important to further prevent progression of the disease.

However, the topic of sports and Hashimoto’s is not thoroughly researched [2], but here are several things that we do know, or can conclude from the scientific research that has been published so far.

1. Too much sports might work against your thyroid

Too intense, too lengthy or too frequent exercise may not allow enough time for restoring normal levels of thyroid hormones T3 and T4 (3, 4).

As thyroid hormones are absolutely necessary for the utilization of our body’s energy reserves by all the cells, if they did not recover, you might feel unexpectedly tired after exercise.

General recommendations are to allow a day or two resting period between workouts, and to establish what is a good balance of exercise for yourself [3]. Try sticking to a certain routine for two weeks and track your energy and focus levels. This will help you find a good zone for you.

2. Sports are crucial to maintain healthy weight and healthy body

Regular exercise is indispensable for preventing health complications. It will improve insulin sensitivity (5, 6) (important for diabetes), reduce blood pressure (7) and reduce the risk of heart related complications (8, 9).

Whether you want to maintain or reduce your body weight, increase your muscle mass or anything else, it is good to track your activity and see if you have any side effects from exercise.

3. Regular sports are important for proper functioning of the immune system

Regular exercise strengthens the immune system, and makes us more resistant to certain infections, such as the common cold [10].

Doing sports reduces inflammation in the body [11, 12], which is a hallmark of autoimmune diseases. Exercising in regular intervals might help in reducing Hashimoto’s triggered flare-ups.

Physical exercise reduces stress levels, which are found in excess in Hashimoto’s thyroiditis [13]. Finding a correlation between regular sports activity and signs of autoimmune flare-ups, such as disturbed digestion, will help you to establish healthy routines that fit your personal health.
