Chronic Fatigue is extra terrible because sufferers are often persecuted as 'being lazy' when it is very much a real disease out of their control. But what about their Glymphatic system? https://pubmed.ncbi.nlm.nih.gov/30037603/ this article presents an avenue for study.

People with chronic fatigue have a slower brain cleaning system — the worse the cleanup, the more exhausted and foggy they feel. Their brains are literally clogged with toxins that should’ve been flushed overnight. 🧠💧 https://s.fitbodyscience.com/7yxbMU

The breakdown

A sluggish brain cleanup system might be why chronic fatigue feels so crushing.

Other research found that people with chronic fatigue have a noticeably slower brain cleaning system compared to healthy people, and the worse the cleanup, the more exhausted and mentally foggy they feel — which is pretty striking. The study linked in the post doesn’t prove this connection yet, but it hints that something’s off with how the brain clears out toxins, like a clogged drain that might explain why the puddle won’t go away. It’s not the whole story, but it’s a compelling clue that fatigue might be tied to biology, not laziness.

Bottom line

It’s not proven yet, but there’s growing reason to think your brain might just be too tired to clean itself — and that could be part of why chronic fatigue feels so overwhelming.

ReliabilityThe evidence mostly supports this with some caveats
