The Claim
The association between high-frequency heart rate variability (HF-HRV) and immune gene regulation remains significant after controlling for the use of β-adrenergic antagonist medications, indicating that parasympathetic nervous system influences on immune gene expression are independent of sympathetic blockade.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Even if someone is taking medication that blocks certain stress signals in the body, their heart’s natural rhythm patterns still seem to be linked to how their immune genes behave — meaning their body’s relaxation system might directly affect immunity, no matter what the stress drugs are doing.

The association between high-frequency heart rate variability (HF-HRV) and immune gene regulation persists after accounting for β-adrenergic antagonist medication use, suggesting that parasympathetic effects on immunity are independent of sympathetic blockade.
What the research says
1 studyThis study found that when your body’s 'rest and digest' system is more active (measured by heart rate patterns), your immune cells behave differently—fighting viruses better and calming inflammation—even in people taking heart medications that block the 'fight or flight' system. So, your nervous system can still help your immune system even if you’re on those meds.
