The Claim

Long-term fasting is associated with a reduction in systolic blood pressure (p < 0.05) in healthy adults, independent of confinement status.

In plain English

People who fast for extended periods have lower systolic blood pressure compared to those who do not, regardless of whether they are confined or not.

See the scientific wording

Long-term fasting is associated with a reduction in systolic blood pressure (p < 0.05) in healthy adults, regardless of whether they are confined or not, suggesting a consistent physiological effect of energy restriction on vascular tone.

Why this might work

When the body goes without food for a long time, it reduces signals that tighten blood vessels and increases signals that relax them, causing blood pressure to drop.

What the research says

  1. Study: Effects of long-term fasting and confinement on the cardiovascular activity

    When people fast for 10 days, their blood pressure goes down—even if they’re stuck inside or free to move around. This means fasting itself, not being confined, is what lowers blood pressure.
