Do you drink caffeine??

I don’t trust ABC for anything. Going to need to see more information from a trusted and uncorrupted doctor or scientist.

Not saying this isn't true, but, it seems I should be in a vegetative state with the amounts I drink.

From Grok - Drinking coffee actually has the opposite effect on blood flow in the brain. Caffeine, the primary active ingredient in coffee, is a stimulant that can increase blood flow to the brain in the short term. Here's how it works: Caffeine blocks adenosine receptors: Adenosine is a neurotransmitter that promotes sleepiness and reduces brain activity. By blocking these receptors, caffeine prevents adenosine from having its calming effect, which can lead to increased neuronal activity. Vasoconstriction: While caffeine can cause vasoconstriction (narrowing of blood vessels) in other parts of the body, in the brain, there's often a net effect of increased cerebral blood flow due to increased neural activity. However, this might not be uniform; some areas might see a decrease in flow due to vasoconstriction, but overall, the brain's metabolic demand increases, leading to more blood flow to meet that demand. Acute vs. Chronic Use: With acute consumption, you might see an increase in cerebral blood flow. However, with chronic use, there could be some adaptation where the effect might not be as pronounced, or there might be slight reductions in blood flow in certain brain regions due to vasoconstriction. Study Variability: Research on this topic can vary, but many studies indicate that caffeine increases cerebral blood flow in areas involved in attention, alertness, and cognitive processing. However, the exact impact can depend on factors like dosage, frequency of consumption, and individual physiological responses.

Lmao this is false af. If bloodflow was decreased 40% your cognitive function would be so far gone you’d basically be mentally retarded

Whatever the mainstream media tells you, do the opposite! 🤨

BS. 40% drop in blood flow would cause all kinds of problems.

Was your "drink" full of sugar or was it black coffee?

for some reason i think they mixed the results and its opposite ... caffeine is a stimulate meaning higher blood flow ,...

Again Barbara Oneill showing you holistic science. Caffeine is a neurotoxin that after 1 cup of coffee the flow of blood to your brain reduces by 40%, making your IQ equal to suffering from Down Syndrome. That's how you start your day? Drink superfood Red Rooibos tea instead! 👆

Yes Love coffee, tea., Dark Chocolate. No this does not make sense. Evidence Needed SVP. Caffeine can have many health benefits when used in moderation that people can look up and experience for themselves if they are so inclined. As everything, it is definitely not for everyone.🙌🙏🏿🌈
