I heard sleeping 8 hours actually makes you more tired than staying up late?

Between 5 and 7 in the morning, your body naturally raises cortisol. Forcing yourself to lie back in bed is like making your brain misread “there’s a threat,” triggering defensive sleep.

When you close your eyes and open them again, your limbs feel like they’ve been filled with lead, but your head feels like it’s stuffed with cotton.

Am I the only one?
