If you’ve always been a good sleeper but recently find you can’t snooze through the night, it could signal a thyroid problem. An overactive thyroid pumps out certain hormones (triiodothyronine, known as T3, and thyroxine, known as T4) in excess, which can overstimulate the central nervous system and lead to insomnia, says Hossein Gharib, MD, a Mayo Clinic endocrinologist.
On the flip side, if you still feel tired after a full night’s sleep (or need to sleep more than usual), you might have an underactive thyroid, in which your body doesn’t produce enough hormones. Everyone should know these important thyroid facts.
If you’ve never struggled with anxiety but start to feel consistently anxious or unsettled, your thyroid might be hyperactive. Too many thyroid hormones often cause patients to feel jittery or anxious unrelated to anything specific, says Ashita Gupta, MD, an endocrinologist at Mount Sinai Roosevelt Hospital in New York City. “There’s more brain stimulation so it excites you to the point where you don’t feel good about it,” she says. Adopt these habits for a healthy thyroid.
