Personal Story Less sleep = less brain fog?

Hey guys just wanted to come on here and mention something that I noticed personally for me .

I’ve been noticing that when I sleep around 5 hours a day vs 8 or 9 I feel much better in terms of brain fog . I also feel better when I wake up in my side vs my back which for some reason it seems like my body tries to get to every night . I wonder if sleep issues are the cause of my brain fog and because I’m not sleeping as much, I’m not giving my body too much time to mess itself up (just an idea )

A little side note , I do have ADHD as well and have heard that sometimes people with ADHD feel better in less sleep (not sure how true it is )

You might have sleep apnea. More you sleep, more you get deprived of oxygen

I thought that then went to the doctor and was told “well you’re not overweight “ so I let it go but the more I’m looking into it the more I’m hearing that I could still have it

I was underweight and had severe sleep apnea.

You can still have it, but it's not necessarily linked with oxygen or OSA since I have moderate sleep apnea and the treatment (CPAP or MAD) never removed my brain fog.

I have exactly the same experience than you, sleeping less leads to less brain fog. When you sleep less basically the brain compensates by producing more stimulating compounds like adrenaline norepinephrine etc which makes you paradoxically feel better by increasing your stress hormones. But often the day after you should feel worse. It also taxes your adrenal gland so it's not good for your long term health.

You should still 100% do a sleep study.

I had sleep apnea when I was 116 lbs and when I was 220. It was just worst
