How does Ramadan fasting impact my blood circulation?
South Asian Health — Ramadan & Religious Fasting20 October 2026
Fasting during Ramadan can have various effects on your blood circulation. When you fast, your body goes into a state of rest, which can help improve circulation as your heart gets a chance to pump more efficiently. However, dehydration from not drinking water during the fasting hours can negatively affect circulation. It's essential to ensure adequate hydration during non-fasting hours. Consuming nutrient-rich foods during suhoor and iftar can also support healthy blood flow. If you have existing circulation issues or cardiovascular conditions, discuss with your GP about how fasting may affect your health and if any adjustments are necessary during Ramadan.
