TIL that if you wait about 90 minutes after waking for your first coffee, caffeine works with your body’s natural dip in alertness instead of overlapping your cortisol peak, which makes it more effective, reduces dependency, and improves sleep.
Huberman Labs podcast discusses it as well
This is perfect because 90 minutes after waking up is exactly when I normally have my second coffee anyway
AI bullshit. All of the reference links in this article pont to unrelated articles.
Possibly. I asked ChatGPT for an article.
In my defence it was also on the 4th August Huberman Labs podcast talking about controlling cortisol levels.
Possibly.
No. Definitely. Took less than 5 seconds to check.
In my defence
Respectfully, no. There is so defence for posting hallucinated misinfo.
Edit: Also, someone else already posted the video where Hoffman called out Huberman’s BS.
This is the type of micro optimization I just don’t want to care about. It’s cool research, don’t get me wrong, but I’m just gonna go about my day how I feel like.
Do the references work for anyone? For me they lead to completely unrelated studies with no connection to caffeine.
And the “article” itself is clearly AI created. It is all bot hallucinating lies.
James Hoffman called bullshit on this one and it’s fun to see Huberman squirm in the comments. https://youtu.be/yCJr49GU9yY
TLDR: it might nonsense.
Academics know a great deal about the field they study, more than the average person, but they know a lot about their specific niche. More than anyone else in the world — that’s the point. Other academics have their own niche, which may be adjacent, and they can discuss the general subject area knowledgeably, and learn from each others perspectives.
My experience with the conversations of academics when discussing their fields of study is that they swirl ideas around. New areas of research and how to conduct that research - “what if X?” I don’t listen to his podcast very much, but the huberman podcast is a lot of that discussion of ideas. Unfortunately people don’t realize that, while evidence suggests X, it may be a faulty conjecture. It’s not limited to Huberman, and it’s not a knock on the cast. It’s just important to be aware as a listener that not everything said is proven - and that which is may be generalized and extrapolated and may not be true for you.
discuss the general subject area knowledgeably, and learn from each others perspectives.
Wish Huberman did that. Instead, in the comment he went, “you’re wrong”, got defensive, and started gaslighting.
Within 30–45 minutes of rising, your brain releases a surge of cortisol — a hormone that supports alertness, metabolism, and stress response.
I fucking WISH?
The only thing my brain releases is a string desire to return to bed.
I haven’t experienced that morning surge of cortisol since I was nine.
Who the fuck has 90 minutes to chill out before you gotta go to work.
Just snooze 90 minutes before getting up!
As someone who has a lot of anxiety over things not going so well in life recently, I can tell you I get up way earlier than I should be because my mind won’t shut off. I then sit there trying to go back to sleep but can’t. So that’s one way!
Does this study assume a 9-5 schedule?
I don’t have a cortisol peak.
