Scientists discovered that sleep deprivation damages a key brain circuit responsible for social memory, making it harder to recognize familiar individuals. In laboratory studies, caffeine restored communication between neurons in this pathway and reversed the memory deficits caused by lost sleep. The effect was remarkably targeted, helping the impaired circuit recover without overstimulating normal brain function.

Apparently all the coffee I'm drinking is the only thing holding me together. Well, I'm already feeling the effects of impaired memory even with that, but good to know the irreversible brain damage could be even worse, I guess.

Same boat my man.

My wife said I was snoring a lot and made me get a sleep study.

Turns out I stop breathing and my SpO2 got down to the 70s. Basically hypoxia. Thankfully only very briefly.

But wait, there's more! No N2 or REM sleep was recorded.

So not only do I stop breathing, I also don't even get to the important part of sleep. I'm basically wasting my time laying there all night with my eyes shut. I wake up knowing that I "slept" but not realizing that it was horrible, worthless sleep that almost killed me.

I got a special type of mouthguard/nightguard/bite splint, or whatever this thing is called in English, that holds my lower jaw in front when I sleep, basically an underbite. This way, I can breath more easily, my wife says I don't snore anymore and I don't wake up in the middle of the night. Sleep apnea got way better. Been using it for several months now, so I don't know what years of usage will eventually bring, but for now I'm happy.

Lowest SpO2 recorded was 68 for me.

Until I got my CPAP, I was literally getting more tired by sleeping. I was more energetic and attentive when I only slept ~3 hours at night.

Now any time I hear anyone complain about being tired constantly, or snoring or suffocating in their sleep, I tell them to get a sleep study done.

Funnily enough, people mostly go there because of the snoring, but the snoring isn't dangerous part. You have to be breathing to snore! That bit of course ruins your wife's sleep though.

I thought Ginkgo had no proven health benefits? I'm keeping an eye on Lion's Mane Mushroom though.

[-] boonhet@sopuli.xyz 2 points 1 week ago

Screw the ginkgo supplements, plant a ginkgo tree instead. They're cool.

Now this I can get behind. As a coelacanth I am unsurprisingly quite fond of living fossils.

[-] ChicoSuave@lemmy.world 1 points 1 week ago

Could be. I only remember ginkgo claims from 30 years ago and since it never crossed my path I haven't looked into it.

Bruh

The title of the original paper is “# Caffeine reverses sleep deprivation-induced synaptic and social memory deficits via adenosine receptor modulation in the male mouse hippocampal CA2 region”

I think OP made a pretty good title of that

Which is less approachable way to same the same exact thing

[-] Viceversa@lemmy.world 2 points 1 week ago

More accurate > less approachable

I’m done wasting my time with an idiot troll like you. You called it clickbait, its a perfectly accurate title, fuck off.

This is one of the less click-baity titles I've seen in a while. What are you talking about?

[-] Viceversa@lemmy.world 2 points 1 week ago

It says "Memory problems" , which without clarification reads as "all memory problems"

This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
