The Claim

Ramadan intermittent fasting does not significantly alter systolic or diastolic blood pressure in adults with controlled hypertension who continue their antihypertensive medications, despite changes in circadian rhythms and meal timing.

Description
1 study reviewed
In plain English

In adults with controlled high blood pressure who take their blood pressure medications, fasting during Ramadan does not change their systolic or diastolic blood pressure readings, even though their eating and sleeping patterns change.

See the scientific wording

Ramadan intermittent fasting does not significantly alter systolic or diastolic blood pressure in adults with controlled hypertension who continue their antihypertensive medications, despite changes in circadian rhythms and meal timing.

Why this might work

When a person fasts for long periods, the body shifts from a state of stress to a state of rest by increasing calming signals from the nervous system and reducing activating signals. This shift keeps the heart rate steady and prevents blood pressure from rising or falling, even when eating and sleeping times change.

1 study
  1. Study: Impact of Ramadan Intermittent Fasting on the Heart Rate Variability and Cardiovascular Parameters of Patients with Controlled Hypertension

    For people with high blood pressure who take their medicine, fasting during Ramadan doesn’t make their blood pressure go up or down in a meaningful way — even if they eat and sleep at different times. Their blood pressure stayed the same.
