I'm waking up full of energy after a doctor helped me fix this simple sleep hygiene mistake I didn't realize I was making

Woman wakes smiling and stretching in a bed with light-coloured bedding.

Good sleep hygiene doesn't start when your head hits the pillow — the hours leading up to bedtime are just as important. As I discovered when I asked a sleep expert why I'm waking up tired and she identified my 'higher-stimulus' environment as the cause of my lower-quality sleep.

So what's a 'higher-stimulus' space? Think bright lights, social media scrolls and lots of flashing screens. Things I keep out of my bedroom but that I'm surrounded by in the hours before sleep.
