How does the winter affect your thyroid?

It’s not in your head — the dark and cold days of winter put an extra burden on the thyroid.

The top three reasons why, according to our research, are:

1. Vitamin D levels dip during the winter, which means you might experience more fatigue, problems with injuries healing, or bone and muscle pain.

Vitamin D is absolutely necessary for a healthy thyroid, healthy immune system, and healthy bones, to say the least. Although the majority of vitamin D comes from sun exposure, vitamin D3 supplements are an excellent solution to compensate during the winter months or even the whole year around, depending where you live.

2. Your thyroid needs to work harder to keep your body temperature up, so you might experience a dip in your fT3 and fT4.

Talk to your healthcare professional to see if it is necessary to change your dose during these months.This is a well-known phenomenon, and it usually does not require medicine adjustments. However, if you start feeling new or stronger symptoms, it might be a good time to talk to your doctor.

3. You might need extra time to warm up for your exercise routines, and you might feel your fitness level is not as high.

Our muscles and joints need warmth to be optimally stretched and ready to endure a standard exercise routine. Cold, in combination with lower than usual thyroid hormones, might mean you need to spend a little more time warming up. Keep up with your exercise routines and allow yourself extra time to get loose.

Have an awesome winter and keep your thyroid healthy all year round!
