🧠 Sleep Science
Ever wake up feeling like your brain is still asleep?
That groggy, sluggish feeling has a name: sleep inertia.
It's a completely normal part of waking up, especially if you're pulled out of a deep stage of sleep. While it usually passes within an hour, things like inconsistent bedtimes, poor sleep quality, and not getting enough rest can make it stick around longer.
Sleep isn't just about how many hours you get; it's about how well those hours help you recover.
