On most days, I'm a stickler for routine, especially when it comes to sleep. I get ready for bed well before I begin to feel tired: changing into my pyjamas, cleaning my teeth, and doing an overly elaborate skin care routine. I leave my phone in the dining room where it stays overnight, then retire to my bedroom. A half-hour of fiction reading follows, before turning the lights out at roughly 11pm.
Eight-and-a-half hours later, my alarm rings and I wake up feeling…tired. I am early mid-life, exercise regularly, and am, as far as I know, healthy (knock on wood). Why, then, does being bright-eyed and bushy-tailed elude me most mornings, despite sufficient sleep?
