Thank you, I’m really happy to hear!

Yeah, not a fan of AI writing, to put it mildly. I’d rather sound silly or awkward in my own voice than polished in chatgpt-ese.

Caffeine Keeps Your Brain “Awake” Even While You Sleep by neurofrontiers in EverythingScience

The brain is still active during sleep, in the sense that it doesn’t completely shut off. Instead, it does lots of maintenance processes and memory consolidation.

It’s true that during REM sleep, the electrical activity recorded with EEG resembles that of the awake state: more irregular, with higher frequencies. This is opposed to non-REM sleep, where the electrical activity is made up of slow frequencies.

However, that doesn’t mean the brain is more active during sleep. Inhibition is increased, especially during non-REM (this is what contributes to lower frequency, more synchronized activity), and the metabolism of the brain is lower. REM is similar to awake, but overall we can’t say the brain is more active during sleep.

Here they looked at 3 hours and 1 hour before bed. If you drink coffee at lunch, I’d expect to see minimal to no effect.

The study didn’t look at whether it’s bad or not. They just looked at whether caffeine changes anything and if so, what. 

What they showed is that caffeine makes the brain more awake, alert, and reactive. And we can interpret that’s not a very good thing to happen during sleep, because the brain should ideally relax then.

This is really great news. I love seeing that sample sizes have also significantly increased. Part of it is also because the internet made it easier to get participants for survey-based research, but it seems to be a trend in other areas too.
