Particularly after lunch, I feel a bit sleepy and I love to take a nap. But many of my friends insist that I take a bit of a walk after my lunch. They recommend it as a healthy habit that helps with digestion.

Is it true? Could anyone point me to some sources that prove or disprove this?

a walk after my lunch [is] a healthy habit that helps with digestion.

Walking may be a healthy habit but it does not specifically assist digestion.

Digestion is a process which takes place in resting conditions. Exercise is characterised by a shift in blood flow away from the gastrointestinal (GI) tract towards the active muscle and the lungs.

  • This answer pertaining to the redirection of blood away from the stomach/GI is most important in documenting the anti-digestive action of movement. – New Alexandria Oct 7 '12 at 18:40
  • Excellent. Thank you! I think now I can take a nap after food without any guilt. :--) – rpattabi Oct 8 '12 at 13:37
