Sleep Optimization: Fall Asleep Faster, Wake Up Rested

Most sleep advice stops at "get 8 hours," but duration is only half the picture — sleep quality, timing, and consistency matter just as much as the number of hours logged. This course walks through how sleep actually works: the 90-minute cycles your body moves through each night, why your circadian rhythm depends on light exposure more than anything else, and how to build a wind-down routine that gets you to sleep faster without a strict, guilt-inducing schedule.

You'll also learn to identify and fix the everyday habits most likely to be quietly wrecking your sleep — caffeine timing, screens, alcohol, and stress — plus how to set up a bedroom environment that works with your biology instead of against it. The final lesson covers where the line is between "a rough patch" and a sleep problem worth getting evaluated by a professional, including red flags for insomnia and sleep apnea.

Every lesson ends with a short flashcard set and a Quick Check quiz, and a final exam ties the whole system together.
