[00:00:00]If you're an adult dealing with that heavy, confused, brain fog feeling right after the alarm goes off, it has a name.

[00:00:06]It's called sleep inertia. It's why you don't remember turning off your alarm, why you say things that make no sense, why the first hour of the day feels like you're thinking through mud. And no, it's not because you're lazy or didn't sleep enough. Here's what's actually happening. Waking up isn't an on and off switch. It's a slow boot up, like a car engine on a cold morning. It turns on, but it needs time to warm up before it runs smoothly. Deep, primitive parts of your brain wake up first, but the front of your brain, the part responsible for thinking clearly and making decisions, that's the last to come online. For some people, it takes 15 minutes, for others, up to 2 hours. So, here's a research-backed routine called rise up that actually helps. R, refrain from snoozing. I, increase activity in the first hour. S, shower or wash your face.
