This Is What 5–6 Hours of Sleep Does to Your Discs
Everyone thinks “I’ll catch up on sleep later.”
Your spine doesn’t work like that.
Your discs are ~90% water.
They need a full 7–8 hours at night to rehydrate.
When your spine isn’t supported and neutral:
– Discs don’t refill
– They start to bulge or herniate
– Nerves get pinched
– You get pain and spasms
For men, those short nights also drag testosterone down.
So one bad habit hits your spine AND your hormones at the same time.
Change your sleep, change your spine, change your mornings.
(Not medical advice. Always consult your doctor about back pain or hormone issues.)
