Sleep Better
How to use this course
Fifteen short lessons take you from “why does sleep matter” to a personal plan you can run for two weeks. Most lessons take 10 to 15 minutes to read and end with something small to try that night or the next morning.
Sleep is different from learning a drum machine: you can’t practise it harder. What you can do is change the conditions around it (light, timing, caffeine, your bedroom, your evening) and let sleep take care of itself. Most of this course is about those conditions.
Everything here comes from published research or recognised health bodies: the Sleep Health Foundation and healthdirect in Australia, the US Centers for Disease Control and Prevention (CDC), the American Academy of Sleep Medicine (AASM) and peer-reviewed studies. Each lesson lists its sources at the end. Where something is a popular tip or a personal habit rather than tested science, the lesson says so.
How to work through it
- Lessons 1 to 3 explain what sleep is and how much you need. Read these first; they make everything else make sense.
- Lessons 4 to 9 are the day-to-day levers: light, caffeine and drinks, your bedroom, winding down, switching off, and what to do when you wake in the night.
- Lessons 10 to 13 are for when sleep is properly broken: the CBT-I techniques sleep clinics use, sleep trackers, shift work and jet lag, sleeping pills and when to see a doctor.
- Lesson 14 pulls it together into a two-week reset you can start tonight.
- Lesson 15 is a toolkit: quick techniques for the nights sleep won’t come (cognitive shuffling, NSDR, breathing and more) and what the evidence says about magnesium and other supplements.
What you need
- A notebook or notes app for a simple sleep diary (Lesson 14 has a template)
- A sleep tracker or smartwatch if you have one (optional; Lesson 11)
- About two weeks of patience: most changes to sleep take one to two weeks to show
Important
This course is general information, not medical advice. See your doctor if you have trouble sleeping most nights for more than a few weeks, if someone has noticed you stop breathing or gasp in your sleep, or if you are sleepy enough to nod off while driving. Lesson 13 covers the warning signs in more detail.
Exercise 0
Before you change anything, write down three numbers for last night: roughly what time you went to bed, what time you got up, and how rested you felt on a scale of 1 to 10. That’s your starting point.
