@yourbrainexplaineddaily: Some people may genuinely need far less sleep than you do — and genetics may be the reason. Most people can’t simply train themselves to function perfectly on four or five hours of sleep. But researchers have identified rare “natural short sleepers” who consistently sleep much less while still waking up feeling rested. Variants in genes including DEC2/BHLHE41, ADRB1, NPSR1, and GRM1 have all been associated with this unusual trait. The important difference is that these people aren’t just forcing themselves to stay awake or becoming used to exhaustion. Their biology appears to regulate sleep need differently. For everyone else, regularly cutting sleep short isn’t the same thing as naturally needing less of it. So while “everyone needs exactly eight hours” is an oversimplification, being able to thrive on very little sleep appears to be genuinely rare.

john raven :

𝐋𝐔𝐃𝐎𝐂𝐈𝐄𝐋 :

watching this at 3am

Andrea :

I sleep 5-6, no matter how much early I try to sleep to make it longer, I would only wake up earlier. if it has to do with my genes, I wonder how much of my genes have mutations... I don't have body odor, my body also doesn't react well to alcohol, I get sleepy after drinking coffee, and a lot other weirdness.

secret :

I just remember that I only sleep 10minites and go in school without sleeping

🪐🇰🇭 :

But if they want to sleep they can over 10 hours a day

Shannon Fernandez :

I cN go 2-3 days without sleeping then finally get 1-3 hours of sleep . if I do sleep daily I only sleep 2 -4 but don't sleep straight through I wake up several time during that time . if I sleep more than 3-4 Hours I feel tired , sluggish during the day

Todd whitacre :
