The Claim

Excessive activation of the sympathetic nervous system through adrenaline surges can trigger flare-ups of autoimmune thyroid disease independently of psychological stress perception.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

When your body releases a lot of adrenaline due to stress or other triggers, it might cause your thyroid to flare up—even if you don't feel stressed at all.

Excessive sympathetic nervous system activation via adrenaline surges can trigger autoimmune thyroid flare-ups independent of perceived psychological stress.

What the research says

2 studies
  1. Study: Thyroid test abnormalities in traumatic brain injury: correlation with neurologic impairment and sympathetic nervous system activation.

    When people suffer serious head injuries, their body releases stress chemicals like adrenaline, which can mess up thyroid function—even if they don’t feel stressed. This suggests that adrenaline surges alone, not just emotional stress, can trigger thyroid problems.

  2. Study: ADGRA1 negatively regulates energy expenditure and thermogenesis through both sympathetic nervous system and hypothalamus–pituitary–thyroid axis in male mice

    This study found that when a specific brain gene is turned off in male mice, their body's stress system goes into overdrive and causes their thyroid to produce more hormones—even without any emotional stress. This suggests that just having too much adrenaline can mess with the thyroid, which supports the idea in the claim.
