Although we have seen findings that show coffee decreases blood flow in the brain, studies are actually showing that drinking coffee can increase blood flow within the body. In one study that analyzed 27 adults, age 22-30 who did not regularly drink coffee, it was found that drinking just one cup of coffee significantly increased blood flow within their fingers. Measuring the blood flow within the fingers in indicative of how well the body’s smaller vessels are pumping blood. When caffeinated coffee was compared with decaffeinated coffee, the caffeinated version was found to increase blood flow by 30% over a period of 75 minutes. While research on the effects of coffee on the blood is still relatively new, increased blood flow is beneficial to overall health and promotes heart, muscle and artery health along with increased oxygen levels in the blood.
