Doctors Debunk 13 Caffeine Myths | Debunked

[kurei.]

I think the myth for coffee being unhealthy is related to other factors and lifestyle choices. Usually if you see a friend drinking an excessive amount of coffee it's because they're overworking themselves or lacking in sleep which is harmful and we just associate that with the coffee because it's used as a crutch to maintain the unhealthy lifestyle. like everything else, moderation is the key.

Thanks INSIDER for having us on! We clearly had a lot of fun digging into the science of caffeine!

This was actually super fascinating. These two have an undeniable chemistry, and it's nice to see some of the health benefits coffee DOES actually provide being highlighted.

I would love to hear these two doctors talk on other topics - clear, relaxed presentation.

"Coffee stunts your growth" was clearly a scary story to keep kids from getting a caffeine buzz and annoying their parents.

The cancer thing is something I’ve actually read studies on. They applied patches of caffeine on cancer cells, and over time, it actually reduced the cancer cells. It also can help rebuild synapsis in the brain (to a degree of course). It thrills me that it can reduce the risk of stroke. I certainly love me some coffee, and only take breaks from it due to the tolerance I build up. It’s just part of my routine, and it is the only way I like to have milk in my daily diet.

They talk so calmly. I can hear them narrating all day

I wish they had discussed caffeine and anxiety and caffeine sensitivity. Still a great video. Very informative.

[Keef_Chief]

Caffeine gives me anxiety. I stopped drinking coffee after a bad anxiety attack. After I stopped drinking coffee, I started having the most vivid dreams.

[AverageBear-ly]

Like many other people have said...these are the people who I would LOVE to have as my doctor. Relaxed, knowledgeable and experienced....they really give a sense of confidence to a patient.

[Brattybat]

I think the “coffee stunts your growth” myth started as a way to get children not to drink it. My grandma would always jokingly say that to me while handing me a cup of coffee when I was young

[breal]

No one addressed the yellowing of the teeth due to caffein stains. Other than that, this was informative and entertaining.

[prague]

These two have great chemistry (doctor jokes aside). I'd love to hear them educate on most anything. Bravo.

Good stuff, thanks for this video. On the subject of caffiene and sleep: I avidly read Matthew Walker's "Why We Sleep, " and have followed a lot of the conversations subsequently with other sleep researchers, and this Q & A here is almost 100% consistent with those conversations. The one point that jumped out at me as not being consistent was about caffiene and sleep. I believe(?) the hypothesis that later-in-the-day caffiene consumption doesn't affect your sleep, or that it will for some and not for others, has been largely rejected. Dr. Iroku kinda touched on this during the discussion, which is that the average half-life of caffiene in your system means that if you drink it in the evening, "sleep hygiene" is negatively impacted... in *all* people. No doubt the impact is greater in some than in others, but Walker is pretty adamant from his work and his reading of others' sleep research that, even if you can 'fall asleep' after an evening espresso, the quality of sleep you are getting is measurably and consistently not as good quality, across pretty much all test subjects. Anyway, thank you for highlighting the importance of sleep, and also that coffee/caffiene is not the devil!

“Caffeine is not addictive but expect withdrawal symptoms after going cold turkey” 😂

[monicatoro]

The chemistry of these two is amazing! Hope to see them together again in a video! :)

[jimholmes]

As a chemist, yes caffeine is additive by definition, it is also an easy to break addiction. Fast acting drugs tend to build tolerance and dependency fast, but are relatively easy to break. Caffeine and nicotine are at the top of that list, whereas alcohol is towards the bottom and much more dangerous to go cold turkey with.

[anahitaariadne]

Just wanted to say how lovely I find these two doctors! Thanks for explaining everything so well.

[firbolg]

As someone who drank 8 espressos per day while trying to juggle work and finishing my engineering degree... while sleeping less than 5h per day for 5 years... I can attest it's a bad idea! I ended up burning out and suffering from serious health issues due to not listening to my body.

[GodOfReality]

Slight nitpick, as far as I know something is "addictive" if there are withdrawl symptoms. It's not about severity, it's about if they exist at all. The fact that stopping your intake of caffeine leads to measurable and concrete withdrawl symptoms means it absolutely is addictive. It's just a very minor addiction that is relatively easy to ease off from. It seems somewhat harmful to say things are "addictive" only if they're "addictive enough."
